SAFE USE  
CAUTION!  
Never operate a chain saw with one hand only. Doing so may lead to i serious injury  
to operator, helpers or bystanders. An electric chain saw is designed for operation  
with both hands.  
DANGER!  
Use of accessories not conforming to the recommendations outlined in the  
Operating Instructions could lead to injury.  
• Dress safely. Avoid jewellery and loose-fitting clothing,  
which may be caught in moving parts. Approved safety  
mitts and sturdy footwear which gives a good footing are  
recommended (also for helpers).  
Wear: - Approved face mask or safety goggles  
- Approved hearing protection  
- Approved helmet  
- Approved safety boots with protective rein-  
forcement, steel toecap and non-slip soles  
- Clothing which is snug without hampering  
movement  
- Approved gloves with protective reinforcement  
Always keep a rst-aid kit on hand!

See to it that others keep their distance as long as the  
chain is in motion. Keep onlookers, children and animals  
away from the work area. Do not let inexperienced persons  
handle the chainsaw or power cable.  
Ensure that you can move and stand safely at all times.  
Watch out for roots, stones, branches, holes, mounds  
and so forth when moving around. Be particularly careful  
when working on slopes. Work with the trunk to your right,  
keeping the log between you and the guide bar. Always grip  
your chain saw with both hands, holding it as close to your  
body as possible for best control. Wherever possible, let  
the log take the weight of the chain saw. Always keep the  
log between you and the guide bar when moving forward.  
Keep work area clear and well-lighted. Do not operate chain  
saw under wet or humid conditions, around water or in rain  
or snow. Ingress of moisture into the motor can cause short-  
circuiting.  
Show caution, care and common sense. Do not operate  
the chain saw when you are tired or under the influence  
of alcohol or drugs which may affect vision, judgement or  
physical control. Keep all body parts well away from the  
chain as long as the motor is running. Always ensure that  
the chain is not touching anything before starting the chain  
saw.  
Do not bear down hard when cutting. With the chain  
properly sharpened, light pressure is sufficient. Forcing the  
saw at the end of a cut can make you lose control when you  
break through.  
Secure short logs before sawing.  
Show particular care when cutting small branches, and  
avoid sawing bushes or many small branches at once.  
Small branches can get caught in the chain with a violent  
jerk and cause serious personal injury.  
Be on your guard against electric shock. Avoid touching  
metal objects imbedded in or in electrical contact with the  
ground.  
Do not abuse power cables. Never lift or carry the chain  
saw by the power cable, and never disconnect the power  
by jerking on the cable. Keep cable away from water, oil  
and sharp objects. Avoid crushing cable in or against  
doors, fences, or other metal objects which can conduct  
electricity.  
We recommend limiting tree diameter to guide bar length so  
that the NOTCH and FELLING CUT may be done with single  
cuts. (See «Technical Specifications» for recommended  
guide bar lengths for your chain saw model).  
Inspect the chain saw and power cable before use. Do not  
use a chain saw with a damaged cable. Get it repaired by  
qualified service personnel. Keep handles clean, dry and  
free of grease and oil.  
See to it that all tools are removed from the chain saw  
before connecting the power.  
Ensure that the extension cord is in good condition and  
approved for outdoor use. It must be of sufficient dimension  
for the chain saw’s rated power. See section «IMPORTANT!  
READ BEFORE USING CHAIN SAW» on page 1.  
The chain will keep rotating a short while after releaseing  
the power trigger (slowness).  
When carrying the chain saw, stop the motor, keep your  
finger AWAY from the power trigger and turn the saw with  
the guide bar to the rear and pointing away from your  
body.  
Disconnect power supply before servicing chain saw.  
Your chain saw complies with all relevant safety standards.  
Repairs should be performed only by qualified service  
personnel using only original parts.  
Connect chain saw to a power supply equipped with a  
current-operated earth-fault protection device.  
Examine saw closely for damaged parts before use to avoid  
malfunctions and to ensure safe and efficient operation.  
Verify that all moving parts are fitted and adjusted correctly.  
Except for the maintenance described in this operator’s  
manual, damaged parts must be replaced at an authorized  
service centre. Defective power triggers are to be replaced  
by authorized service personnel. Do not operate the saw if  
the power trigger does not work properly.  
Double-insulated! Your electric chain saw is double-  
insulated for added protection against electric shock. A  
double-insulated electric tool is designed with two separate  
«layers» of electrical insulation or one layer of insulation  
of double thickness between the operator and the tool’s  
conducting parts. Double-insulated tools do not use earthed  
mains connections and may therefore be connected to any  
normal 220-240 VAC outlet. Observe the same precautions  
required with all electric tools. Double insulation gives  
added protection only against defective insulation.  
Store the chain saw in a safe, dry place out of the reach of  
children, with the power disconnected and the guide bar  
scabbard in place.  
Use chain saw only on wood. Do not attempt to cut metal, plastic,  
masonry or any non-wood building materials. Do not use the  
guide bar to push away branches, roots or other objects.

STARTING AND STOPPING  
CAUTION!  
Make certain at all times that your footing is  
secure and that the chain touches nothing  
but the wood you are cutting.  
Keep bystanders away from your work area.  
Starting  
Grip the front handle firmly with your left hand.  
Grip the rear handle firmly with your right hand.  
Press and hold the power trigger lockout button with the inside of your  
hand and squeeze the power trigger with your index finger.  
Stopping  
Stop the saw by releasing the power trigger. If the saw does not stop,  
trip the chain brake and disconnect the power cable.  
DAILY INSPECTION AND MAINTENANCE  
CAUTION!  
Always disconnect the power before cleaning or performing maintenance.  
Here are a few general instructions for maintaining your hand-  
saw. If you are in doubt on any of these points, contact your  
service dealer.  
1. Inspect power cable and plug for defects.  
A damaged power cable or plug must be replaced.  
2. Clean ventilation openings and keep them open.  
3. Check automatic chain lubrication.  
4. Turn guide bar over at regular intervals to distribute the  
wear on both sides. Check to see that the oil passage is  
clear. Clean the guide bar groove.  
5. Check chain tension, sharpen the cutters and ensure that  
chain turns easily.  
6. Check drive sprocket for abnormal wear, replacing it if  
necessary.  
7. Remove any burrs from the edges of the guide bar

KICKBACK PREVENTION  
DANGER!  
Kickbacks occur suddenly and without warning. A kickback may be violent enough to throw a  
chainsaw back at the user. A running chain can inict severe and even fatal injury. It is imperative  
for users to be familiar with the causes of kickbacks in order to exercise the proper care and use  
working techniques to prevent kickback.  
CAUTION!  
Improperly sharpened cutters or the wrong chain and guide bar combination will  
increase the risk of kickback. See «Technical Specications» on page 3.  
CAUTION!  
Do not let the chain come in contact with the ground or any objects. Chain link and wire fencing  
materials present a particular kickback hazard.  
Observe all safety rules in order to avoid kickbacks and other  
accidents which may cause injury.  
A kickback is a sudden reaction in which a chain saw is  
thrown back as a result from contact with the upper part of  
the bar nose known as the kickback danger zone.  
The direction of a kickback is always in the same plane as  
the guide bar. The most common reaction is that the guide  
bar and saw are thrown up and back towards the operator.  
The saw can be thrown in other directions, depending on  
the position of the saw at the moment of kickback.  
Basic rules  
Take extreme care when cutting with the top chain (on the  
underside of a log). The force of the chain action pushes the  
saw backwards, and if the operator does not maintain firm  
control, the kickback danger zone may move far enough  
back into the kerf to produce a kickback. Cutting with the  
bottom chain (on the top side of the log) pulls the saw for-  
ward. This presses the power head firmly against the tree,  
providing a steady support and giving the operator added  
control over the saw and consequently over the kickback  
danger zone.  
Knowing the cause and nature of a kickback helps reduce  
or eliminate the element of surprise. Surprise increases the  
danger of an accident. Most kickbacks are small, but some  
are violent, and all are lightning-fast.  
Always grip the chain saw firmly with thumb and fingers  
wrapped around the handles, right hand on the rear handle  
and left hand on the front handle. All users, whether right or  
left-handed, must use this grip, which will reduce the effect  
of a kickback and help keep the saw under control.  
Do not let go of the chain saw handles!  
Most accidents caused by kickbacks take place in con-  
nection with limbing. Make certain your footing is secure  
and that there are no objects nearby which may trip you  
or make you lose your balance. If you are not careful, the  
kickback danger zone could make contact with a branch,  
a nearby tree or some other object which could cause a  
kickback.  
Follow the maintenance and sharpening instructions for the  
chain and guide bar. When replacing chains and guide bars,  
use only combinations recommended by us. See «Technical  
Specifications».  
The smaller the bar nose radius, the smaller the kickback  
danger zone and thus  
Never use a chain saw to cut above shoulder height, and  
do not cut with the guide bar nose. Never operate a chain  
saw while holding it with only one hand!  
the kickback tendency.  
By using low-kickback  
cutting equipment and  
keeping the cutters  
properly sharpened, the  
strength of a kickback  
can be greatly reduced.  
Maintain full speed while cutting.

CHAIN BRAKE WITH KICKBACK GUARD  
The chain brake may be activated manually or by the force  
of inertia depending on the strength of the kickback and  
the position of the saw in relation to the object which made  
contact with the kickback danger zone.  
Your chain saw is equipped with a chain brake designed to  
stop the chain instantaneously in the event of a kickback.  
A chain brake can reduce the risk of accident, but only the  
operator can prevent accidents from happening. Be extremely  
careful when operating a chain saw and do not allow the kick-  
back danger zone to make contact with anything.  
- If the kickback is sufficiently violent and the left hand  
is too far from the kickback guard, the chain brake is  
activated by the INERTIA of the chain brake against the  
force of the kickback.  
The chain brake (A) is activated either manually (with the left  
hand) or by the force of inertia (the inertia of the kickback  
guard resisting the motion of the saw from the force of the  
kickback). However it is activated, the kickback protection  
mechanism works in the opposite direction to the force of  
the kickback. The saw incorporates a slip clutch which pro-  
tects the saw against overload. If the chain stops while the  
motor is running, the saw is overloaded. Ease up on the  
cutting pressure until the chain starts running again. If the  
saw jams in the tree, stop the saw immediately and free it.  
- In the event of smaller kickbacks or when the left hand  
is near the kickback guard, the chain brake is activated  
manually with the left hand.  
When the chain saw is turned on its side and the operator  
is holding the side of the front handle, the kickback guard  
will not strike the left hand in the event of a kickback and  
will thus not activate the chain brake. In a situation of this  
type, inertia is the only thing that can activate the chain  
brake, but like manual activation, it will not work in every  
situation.  
Kickback guard inspection  
The chain brake is also activated when the kickback guard  
(B) is pushed forward. This releases a springloaded mecha-  
nism which jerks the brake band tightly around the brake  
drum.  
Inspect kickback guard for visible defects, such as cracks.  
Move kickback guard back and forth to ensure that it moves  
freely without being loose.  
Manual chain brake function check  
Check chain brake daily or every time the saw is used.  
Holding the running saw firmly with the left hand on the  
front handle and the right hand on the rear handle, twist  
your left wrist, pushing the kickback guard to activate the  
chain brake without letting go of the front handle. The chain  
should stop instantaneously. If the chain brake does not  
perform as required, have it serviced by authorized per-  
sonnel.  
The purpose of the kickback guard is not only to activate  
the chain brake. Its other important function is to reduce  
the danger of contact with the chain in the event that the  
operator loses his grip on the front handle.  
Inertia chain brake function check  
Use the chain brake as a «parking brake» when carrying  
the chain saw around or putting it down for short periods!  
Besides automatic activation in the event of a kickback, the  
chain brake may also be activated manually and must be  
activated in the event of any inadvertent contact with a ro-  
tating chain.  
Hold the running saw level with the guide bar approximately  
45 cm above a stump or other solid wooden object.  
Release the power trigger.  
Release the front handle, letting  
the chain saw pivot in your  
right hand as the guide bar falls  
down and strikes the stump.  
The brake should activate when  
the bar nose hits the stump.  
An activated chain brake is released by pulling the kickback  
guard back towards the front handle.  
As pointed out on page 7, a kickback can be extremely  
violent and lightning-fast. Most kickbacks are small and do  
not activate the chain brake. When this happens, it is im-  
portant to maintain a firm grip on the saw and not let go.

MOUNTING GUIDE BAR AND ADJUSTING CHAIN  
CAUTION!  
Always disconnect power before performing cleaning or maintenance work.  
CAUTION!  
A loose chain can jump out of its groove during operation and cause serious  
or even fatal injury.  
6. Replace the chain drive cover and screw  
the mounting nut hand tight.  
1. Pull kickback guard back against the front handle  
to ensure that the chain brake is not applied.  
7. Tension the chain by screwing the  
tensioning screw clockwise using the  
screwdriver tip on the combination  
tool.  
2. Screw out the guide bar nut and remove  
the chain drive cover.  
8. Tighten chain firmly but not so hard that it does not turn easily  
by hand force. Push the button to release the chain brake. To  
avoid contact between your hands and the chain, use gloves  
to turn the chain.  
8
2
3. Fit the chain around guide bar nose with  
the top cutters facing forwards.  
9. Tighten the mounting nut with the combination tool while hold-  
ing the tip of the guide bar up.  
4. Holding the chain over the guide bar nose, position the  
back end of the guide bar against the drive sprocket at a  
45° angle to the power head. Pass the free end of the chain  
around the drive sprocket, swing the guide bar into place  
over the mounting bolt and against the power head, and  
guide the chain into the guide bar groove.  
The tension of a new chain must be checked frequently until it  
is broken in. Continue to check the tension at regular intervals  
to ensure good performance and a long service life.  
Wear causes a chain to become looser with use. Regular  
tensioning is important to compensate for this wear.  
5. Seat the guide bar tensioner pin in its hole in the guide bar.  
Check the chain tension at least every time you refill the chain  
oil reservoir.

CHAIN CATCHER  
The chain catcher is designed to catch a chain which breaks or jumps out of its groove.  
This problem will generally be avoided, however, if the chain is tensioned properly (see  
chapter on «Mounting guide bar and adjusting chain» page 9) and the chain and guide  
bar properly maintained.  
Ensure that the CHAIN CATCHER is undamaged.  
RIGHT HAND GUARD  
The right hand guard protects the right hand in the event that the chain breaks or  
jumps out of its groove, as well as keeping twigs and branches from interfering with  
your grip on the handle.  
Ensure that the RIGHT HAND GUARD is undamaged.  
SLIP CLUTCH  
Your chain saw features a slip clutch which protects it from overload.  
The slip clutch may require cleaning after long periods of operation.  
Contact your nearest service dealer in the event of malfunction.  
ELECTRONIC OVERLOAD PROTECTION 2000W  
The 2000W electric chain saw is provided with electronic overload protection.  
When the overload protection trips, the saw stops.  
Release the power trigger. Ensure that the chain is not stuck.  
Squeeze the power trigger.  
CUTTING EQUIPMENT  
This section explains how correct maintenance and use of the  
right cutting equipment:  
Ensure that the cutter teeth are always  
correctly sharpened! Follow our  
instructions and use the recommended  
ling guide. A chain which is damaged or  
improperly maintained increases the risk  
of accident.  
Reduces kickback tendencies  
Reduces the frequency of chain derailing and breakage  
Achieves maximum cutting effect  
Maintain the correct depth-gauge height.  
Worn depth gauges increase the risk of  
kickback.  
Increases the service life of the chain  
Keep chain properly tensioned!  
A loose chain derails more easily and  
accelerates wear on guide bar, chain  
and drive sprocket.  
The ve basic rules  
Use only the recommended cutting equipment!  
See «Technical Specifications» on page 3.  
Ensure that the automatic oiling system  
works and that the cutting equipment is  
properly maintained.

CHAIN AND GUIDE BAR LUBRICATION  
CAUTION!  
Inadequate lubrication can lead to cutting equipment failure and serious or fatal  
personal injury.  
Chain oil  
A full reservoir is sufficient for 20 minutes of steady use.  
The chain and bar are lubricated by an automatic oiling  
system. We recommend using only chain saw oil, which is  
formulated for good adhesion and flow characteristics in hot  
or cold weather. Nonetheless, it is important to use the vis-  
cosity appropriate to the season. Oil thickens in subfreezing  
temperatures and can overload the oil pump and cause  
parts to fail.  
If the lubrication system does not seem to be working, and  
the following steps do not help, take your saw to a service  
dealer.  
-
Check the guide bar’s oil passage  
and clean if necessary.  
As a manufacturer of chain saws, we have developed an  
ideal chain oil which, being based on vegetable oils, is  
completely biodegradable. We recommend our oil for the  
sake of your chain and guidebar and for the sake of the  
environment.  
-
Check guide bar groove and  
clean if necessary.  
Where chain oil is not available, EP 90 gear oil may be used.  
If you need help choosing chain oil, contact your service dealer.  
Never use old motor oil! Used motor oil contains impurities  
which may be harmful to oil pump, guide bar and chain.  
-
Ensure that the nose sprocket  
turns easily and is not clogged.  
Clean and grease if necessary.  
Filling chain oil  
All our chain saw models feature automatic chain lubrication.  
Checking chain wear  
Inspect chain every day for:  
-
Visible cracks in rivets or links  
Stiffness

Start the chain saw and point the guide bar towards a fixed,  
light-coloured object at a distance of approximately 20 cm.  
After running the saw for a minute, a streak of oil spatter  
should be clearly visible on the light surface.  
Abnormal wear in rivets or links  
Min. 3 mm (1/8”) horizontal cutter length  
Any deviation on any of these points indicates a worn chain which  
must be discarded

FILING CHAIN  
See «Technical Specifications» for the details which apply to  
General instructions regarding cutters  
your chain. It is very difficult to file a chain saw correctly with-  
out the proper aids. We recommend the use of a file guide to  
ensure maximum cutting efficiency with the least tendency to  
kickback.  
Never cut wood using a dull chain. Having to press hard is a  
sure sign of a dull chain, as are very small chips. A very dull  
chain will produce sawdust rather than chips.  
Filing cutters  
To le cutters correctly, a ROUND FILE  
and a FILE GUIDE are required. Look  
under «Technical Specifications» for  
the correct file diameter and file guide  
for your saw and chain.  
A sharp chain will produce large chips, and the saw will  
feed itself through the wood.  
The part of the chain that saws is  
called the CUTTING LINK, which  
consists of a CUTTER (A) and  
DEPTH GAUGE (B). The difference  
in height between them determines  
the depth of the cut.  
File only with the chain  
properly tensioned. A loose  
chain wiggles, making it  
difficult to file.  
Always file from the inside of each  
cutter towards the outside. Lift  
the file on the return stroke.  
When filing a saw, pay close attention to:  
TOP-PLATE ANGLE  
CUTTING ANGLE  
HORIZONTAL FILE ANGLE  
FILE DIAMETER  
File the cutters on one side first.  
Then turn the saw around and file  
the cutters on the other side.  
Make certain that all cutters are of  
equal length. When the horizontal  
length is down to 3 mm (1/8”), the  
chain is worn out and must be dis-  
carded.  
FILE DEPTH  
CAUTION!  
Improperly led cutters heighten  
kickback tendencies!  
LIMBING  
CAUTION!  
Most kickback accidents take place when limbing. Pay very close attention to the  
kickback danger zone when cutting limbs under tension!  
All the principles which apply to crosscutting also apply when cutting thick branches.  
Cut complicated branches in several stages.  
Ensure that your footing is secure at all times, whether moving about or  
standing in one place. Always work with the log to your right. For best control,  
hold the chain saw as close to your body as possible.
