4. For safe operation  
1. Never operate a chain saw when you are  
fatigued, ill, or upset, or under the  
influence of medication that may make  
you drowsy, or if you are under the  
influence of alcohol or drugs.  
8. Before you start the engine, make sure  
the saw chain is not contacting anything.  
9. Always carry the chain saw with the  
engine stopped, the guide bar and saw  
chain to the rear, and the muffler away  
from your body.  
2. Use safety footwear, snug fitting clothing  
and eye, hearing and head protection  
devices.  
10. Always inspect the chain saw before  
each use for worn, Ioose, or changed  
parts. Never operate a chain saw that is  
damaged, improperly adjusted, or is not  
completely and securely assembled. Be  
sure that the saw chain stops moving  
when the throttle control trigger is  
released.  
3. Always use caution when handling fuel.  
Wipe up all spills and then move the  
chain saw at least ten(10) feet(three(3)  
m) from the fueling point before starting  
the engine.  
3a) Eliminate all sources of sparks or  
flame (ie. smoking, open flames, or  
work that can cause sparks) in the  
areas where fuel is mixed, poured, or  
stored.  
11. All chain saw service, other than the  
items listed in the Operator’s Manual,  
should be performed by competent chain  
saw service personnel. (e.g., if improper  
tools are used to remove the flywheel, or  
if an improper tool is used to hold the  
flywheel in order to remove the clutch,  
structural damage to the flywheel could  
occur which could subsequently cause  
the flywheel to disintegrate).  
3b) Do not smoke while handling fuel or  
while operating the chain saw.  
4. Do not allow other persons to be near  
the chain saw when starting the engine  
or cutting a wood. Keep bystanders and  
animals out of the work area. Children,  
pets, and bystanders should be a  
minimum of thirty(30) feet away when  
you start or operate the chain saw.  
12. Always shut off the engine before setting  
it down.  
13. Use extreme caution when cutting small  
size brush and saplings because slender  
material may catch the saw chain and be  
whipped toward you or pull you off  
balance.  
5. Never start cutting until you have a clear  
work area, secure footing, and planned  
retreat path from the falling tree.  
6. Always hold the chain saw firmly with  
both hands when the engine is running.  
Use a firm grip with thumb and fingers  
encircling the chain saw handles.  
14. When cutting a limb that is under  
tension, be alert for spring back so that  
you will not be struck when the tension in  
the wood fibers is released.  
7. Keep all parts of your body away from  
the saw chain when the engine is  
running.  
15. Keep the handles dry, clean and free of  
oil or fuel mixture.

4. For safe operation  
16. Operate the chain saw only in well  
ventilated areas. Never start or run the  
engine inside a closed room or building.  
Exhaust fumes contain dangerous  
carbon monoxide.  
19. When transporting your chain saw, make  
sure the appropriate guide bar scabbard  
is in place.  
20. This chain saw is equipped with a spark  
arrester built-in muffler. Periodically  
check the arrester to keep it in good  
order.  
17. Do not operate a chain saw in a tree  
unless specially trained to do so.  
18. Guard against kickback. Kickback is the  
upward motion of the guide bar which  
occurs when the saw chain at the nose  
of the guide bar contacts an object.  
Kickback can lead to dangerous loss of  
control of the chain saw.  
KICKBACK SAFETY PRECAUTIONS FOR  
CHAIN SAW USERS  
– WARNING –  
Kickback may occur when the nose or tip of the guide bar touches an object, or when the  
wood closes in and pinches the saw chain in the cut. Tip contact in some cases may  
cause a lightning fast reverse reaction, kicking the guide bar up and back towards the  
operator. Pinching the saw chain along the top of the guide bar may push the guide bar  
rapidly back towards the operator. Either of these reactions may cause you to lose  
control of the saw which could result in serious personal injury.  
Do not rely exclusively on the safety devices built into your saw. As a chain saw user you  
should take several steps to keep cutting jobs free from accident or injury.  
(1) With a basic understanding of kickback you can reduce or eliminate the element of  
surprise. Sudden surprise contributes to accidents.  
(2) Keep a good grip on the saw with both hands, the right hand on the rear handle, and  
the left hand on the front handle, when the engine is running. Use a firm grip with  
thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce  
kickback and maintain control of the saw. Don’t let go.  
(3) Make certain that the area in which you’re cutting is free from obstructions. Do not let  
the nose of the guide bar contact a log, branch, or any other obstruction which could  
be hit while you are operating the saw.  
(4) Cut at high engine speeds.  
(5) Do not overreach or cut above shoulder height.  
(6) Follow manufacturers sharpening and maintenance instructions for saw chain.  
(7) Only use replacement bars and chains specified by the manufacturer or the  
equivalent.

3. Fit the chain tensioner nut into the lower hole of  
the guide bar, then install the chain cover, and  
fasten the mounting nut to finger tightness.  
(SE3)  
NOTE  
When installing the chain cover, be sure to fit the  
hook completely at the rear end of the cover. (SE4)  
SE3  
4. While holding up the tip of the bar, adjust the  
chain tension by turning the tensioner screw until  
the tie straps just touch the bottom side of the  
bar rail. (SE5)  
5. Keep holding the guide bar up, tighten the  
mounting nut firmly with the attached socket  
wrench.  
6. Rotate the saw chain by hand, wearing a  
protective glove, to see if it turns smoothly  
without noticeable gap between the tie straps  
and the guide bar.  
SE4  
NOTE  
A new chain will expand its length in the beginning  
of use. Check and readjust the tension frequently  
as a loose chain can easily derail or cause rapid  
wear of itself and the guide bar.

6. Fuel and chain oil  
FUEL  
The RedMax engines are lubricated by oil specially  
formulated for air-cooled 2-cycle gasoline engine  
use. If RedMax oil is not available, use an anti-  
oxidant added quality oil expressly labeled for air-  
cooled 2-cycle engine use.  
RECOMMENDED MIXING RATIO  
GASOLINE 32 : OIL 1  
Exhaust emission are controlled by the  
fundamental engine parameters and  
components (eq., carburation, ignition timing  
and port timing) without addition of any major  
hardware or the introduction of an inert  
material during combustion.  
These engines are certified to operate on  
unleaded gasoline.  
WARNING  
The fuel is highly flammable. Do not smoke or  
bring any flame or sparks near fuel.  
HOW TO MIX FUEL  
1. Measure out the quantities of gasoline and oil to  
be mixed.  
2. Put some of the gasoline into a clean, approved  
fuel container.  
3. Pour in all of the oil and agitate well.  
4. Pour in the rest of gasoline and agitate again for  
at least one minute.  
5. Put a clear indication on the outside of the  
container to avoid mixing up with gasoline or  
other containers.  
FOR YOUR ENGINE LIFE, AVOID;  
1. FUEL WITH NO OIL(RAW GASOLINE) – It will  
cause severe damage to the engine inner parts  
very quickly.  
2. GASOHOL – It can cause deterioration of rubber  
and/or plastic parts and disruption of engine  
lubrication.  
3. OIL FOR 4-CYCLE ENGINE USE or WATER  
COOLED 2-CYCLE ENGINE USE – It can  
cause spark plug fouling, exhaust port blocking,  
or piston ring sticking.

too slow, turn the screw clockwise. (OP8)  
4. Make a test cut adjust the H needle for best  
cutting power, not for maximum speed. (OP8)  
CHAIN BRAKE  
The chain brake is a device designed to stop the  
saw chain quickly when kickback occured.  
The brake system equipped on the G310TS units  
is designed to work automatically by sensing  
reaction force. It can also be activated manually by  
pushing the brake lever (front hand guard) down  
forward.  
A yellow cone popping up from the base of the  
brake lever indicates that the brake is on.  
OP9  
Releasing the Brake  
Pull the brake lever up toward the front handle until  
it clicks. (OP9)  
NOTE  
• When the brake worked, immediately release  
the throttle lever and slow down the engine  
speed. Running the engine at high speed while  
braking the saw chain can cause clutch failures.  
• Before starting the day's job, check the condition  
of the brake system as follows:  
1) Start the engine and grasp the handles  
securely with both hands.  
2) While pulling the throttle lever, slowly push  
the brake lever (front hand guard) forward  
with the back of your left hand.

8. Sawing  
NOTE  
• Before proceeding to your job, read “For Safe  
Operation” section. It is recommended to first  
practice sawing easy logs. This also helps you  
get accustomed to your unit.  
• It is not necessary to force the saw into the cut.  
Apply only light pressure while running the  
engine at full throttle.  
• Racing the engine with the chain seized in a  
cutaway can damage the clutch system. When  
the saw chain is caught in the cut, do not  
attempt to pull it out by force, but use a wedge or  
a lever to open the cut.  
GUARD AGAINST KICKBACK  
• This saw is equipped with a special “low  
kickback” chain that greatly reduces the severty  
of kickback should it occur.  
• The saw chain has been tested in accordance  
with American National Standard Safety  
Specifications for gasoline powered chain saw  
(ANSI B175.1 1985) as having an acceptable  
low kickback level. On this saw never use any  
chain other than those recommended on page  
18 of this manual, or which is not designated as  
meeting the ANSI B175.1 kickback levels on this  
saw.  
• Low kickback saw chains are chains which have  
met the kickback requirements of ANSI B175.1  
when tested on the representative samples of  
chain saws below 3.8 C.I.D. specified in ANSI  
B175.1.  
• The guide bar supplied with this saw has an  
under 1.2 inch radius sprocket nose which  
produces a specific kickback energy. Never use  
a bar with a larger nose radius. Use only those  
recommended on page 18.  
• The length of bars has a great effect on  
kickback. Use only those length as specified on  
page 18.  
• This saw is also equipped with a chain brake  
that will stop the chain in the event of kickback if  
operating properly. You must check the chain  
brake operation before each usage by running  
the saw at full throttle for 1 or 2 seconds and  
pushing the front hand guard forward. The chain

8. Sawing  
should stop immediately with the engine  
at full speed. If the chain is slow to stop or  
does not stop then replace the brake band  
and clutch drum before use.  
SA1  
• It is extremely important that the chain  
brake be checked for proper operation  
before each use and that the chain be  
sharp in order to maintain the kickback  
safety level of this saw. Removal of the  
safety devices, inadequate maintenance,  
or incorrect replacement of the bar or  
chain may increase the risk of serious  
personal injury due to kickback. (SA1)  
FELLING A TREE (SA2)  
WARNING  
When you fell a tree, be sure to warn your  
neighboring workers of the danger.  
SA2  
1. Decide the felling direction considering the  
wind, Iean of the tree, location of heavy  
branches, ease of job after felling, and  
other factors .  
2. While clearing the area around the tree,  
arrange a good foothold and retreat path.  
3. Make a notch cut one-third of the way into  
the tree on the felling side.  
4. Make a felling cut from the opposite side  
of the notch and at a level slightly higher  
than the bottom of the notch.  
LOGGING AND LIMBING  
WARNING  
1. Always ensure your foothold as well as  
stability of the tree.  
2. Be alert to the rolling over of a cut log.  
3. Read the instructions in “For safe  
operation” to avoid kickback of the  
saw.  
Before starting work, check the direction of  
bending force inside the log to be cut.
