SECTION 2: POWER SuPPLy

Availability

Circuit Requirements

This machine is prewired to operate on a 110V

power supply circuit that has a verified ground and

meets the following requirements:

Before installing the machine, consider the avail-

ability and proximity of the required power supply

circuit. If an existing circuit does not meet the

requirements for this machine, a new circuit must

be installed. To minimize the risk of electrocu-

tion, fire, or equipment damage, installation work

and electrical wiring must be done by a qualified

electrician in accordance with all applicable codes

and standards.

Nominal voltage ...............................110v/120v

Cycle..........................................................60 Hz

Phase........................................... Single-Phase

Circuit Size.......................................... 15 Amps

A power supply circuit includes all electrical

equipment between the main breaker box or fuse

panel in your building and the incoming power

connections inside the machine. This circuit must

be safely sized to handle the full-load current that

may be drawn from the machine for an extended

period of time.

Electrocution, fire, or

equipment damage may

occur if machine is not

correctly grounded and

connected to the power

supply.

For your own safety and protection of

property, consult a qualified electrician if

you are unsure about wiring practices or

electrical codes in your area.

full-Load Current Rating

The full-load current rating is the amperage a

machine draws at 100% of the rated output power.

On machines with multiple motors, this is the

amperage drawn by the largest motor or sum of all

motors and electrical devices that might operate

at one time during normal operations.

Note: The circuit requirements listed in this man-

ual apply to a dedicated circuit—where only one

machine will be running at a time. If this machine

will be connected to a shared circuit where mul-

tiple machines will be running at the same time,

consult a qualified electrician to ensure that the

circuit is properly sized for safe operation.

full-Load Current Rating at 110v........ 2 Amps

The full-load current is not the maximum amount

of amps that the machine will draw. If the machine

is overloaded, it will draw additional amps beyond

the full-load rating.

If the machine is overloaded for a sufficient length

of time, damage, overheating, or fire may result—

especially if connected to an undersized circuit.

To reduce the risk of these hazards, avoid over-

loading the machine during operation and make

sure it is connected to a power supply circuit that

meets the requirements in the following section.

-7-

model t23108 (mfg. since 7/10)

Download from Www.Somanuals.com. All Manuals Search And Download.

Improper connection of the equipment-grounding

wire can result in a risk of electric shock. The

wire with green insulation (with or without yellow

stripes) is the equipment-grounding wire. If repair

or replacement of the power cord or plug is nec-

essary, do not connect the equipment-grounding

wire to a live (current carrying) terminal.

grounding & Plug Requirements

In the event of certain types of malfunctions or

breakdowns, grounding provides a path of least

resistance for electric current—in order to reduce

the risk of electric shock.

This machine is equipped with a power cord that

has an equipment-grounding wire and a ground-

ing plug (similar to the figure below). The plug

must only be inserted into a matching receptacle

(outlet) that is properly installed and grounded in

accordance with all local codes and ordinances.

Check with a qualified electrician or service per-

sonnel if you do not understand these grounding

requirements, or if you are in doubt about whether

the tool is properly grounded. If you ever notice

that a cord or plug is damaged or worn, discon-

nect it from power, and immediately replace it with

a new one.

Serious injury could occur if you connect

the machine to power before completing the

setup process. DO NOT connect to power

until instructed later in this manual.

Extension Cords

We do not recommend using an extension cord

with this machine. If you must use an extension

cord, only use it if absolutely necessary and only

on a temporary basis.

GROUNDED

Extension cords cause voltage drop, which may

damage electrical components and shorten motor

life. Voltage drop increases as the extension cord

size gets longer and the gauge size gets smaller

(higher gauge numbers indicate smaller sizes).

5-15 RECEPTACLE

Grounding Prong

Any extension cord used with this machine must

contain a ground wire, match the required plug

and receptacle, and meet the following require-

ments:

5-15 PLUG

Neutral Hot

figure 2. typical 5-15 plug and receptacle.

Minimum gauge Size...........................14 AWg

Maximum Length (Shorter is better).......50 ft.

DO NOT modify the provided plug or use an

adapter if the plug will not fit your receptacle.

Instead, have a qualified electrician install

the proper receptacle on a power supply

circuit that is grounded and meets the

requirements for this machine.

Site Considerations

Weight Load

Physical Environment

makesurethat thesurfaceupon which themachine

is placed will bear the weight of the machine,

additional equipment that may be installed on

the machine, and the heaviest workpiece that will

be used. additionally, consider the weight of the

operator and any dynamic loading that may occur

when operating the machine.

the physical environment where your machine

is operated is important for safe operation and

the longevity of its components. For best results,

operate this machine in a dry environment that is

free from excessive moisture, hazardous chemi-

cals, airborne abrasives, or extreme conditions.

Extreme conditions for this type of machinery are

generally those where the ambient temperature

range exceeds 41°–104°F; the relative humidity

range exceeds 20–95% (non-condensing); or the

environment is subject to vibration, shocks, or

bumps.

Space Allocation

Consider the largest size of workpiece that will

be processed through this machine and provide

enough space around the machine for adequate

operator material handling or the installation of

auxiliary equipment. With permanent installations,

leave enough space around the machine to open

or remove doors/covers as required by the main-

tenance and service described in this manual.

See below for required space allocation.

Electrical Installation

Mounting

Bolt

the base of this machine has holes for mounting

it to a workbench. Because of the forces applied

to the machine during operation, you must

firmly mount it to a workbench to prevent it

from tipping or shifting during operation. an

unexpected movement could result in injury or

property damage.

Flat Washer

Machine Base

Workbench

Lock Washer

place the base flat on the workbench, slide it

back until the stop flanges (see figure 5) are

against the front of the workbench. mounting the

sharpener in this manner will allow the necessary

access to the chain holder lock knob.

Chain Pitch: the distance between any three

consecutive rivet centers divided by 2 is known as

the chain pitch (see figure 15).

Top Plate Angle: the profile of the cutter link is

shaped like a number "7", and is comprised of

the top plate and side plate (see figure 17). the

rake that the top plate angles back from the side

plate is called the top plate angle and is generally

25°–35°. this makes a sharp point that begins the

cut.

the chain pitch is the same for all links in the

chain. the smallest chain pitch for handheld chain

saws is ⁄4", with ⁄8" and 0.325" being the most

popular.

Chain gauge: the chain gauge is the thickness

of the drive link tang (see figure 16) where it fits

into the guide bar groove. the guide bar groove

must match the width of the chain gauge.

Top Plate Cutting Angle: the top plate cutting

angle (see figure 17) is a chisel-like downward

bevel on the underside leading edge of the top

plate that usually is 60°. the combination of this

cutting angle and the top plate angle serves to

remove wood chips from the kerf.

Chain gauges for handheld chain saws range

from 0.050" for smaller chains to 0.122" for larger

ones.

Side Plate Angle: the ground angle of the side

plate leading edge is instrumental in forming the

cutting point between the side and top plates. this

angle is the same as the top plate cutting angle,

which is typically 60° (see figure 18).

gullet Angle: the cutter gullet (see figure 18)

provides a space for the wood chips so they can

be removed by the top plate. on some chains, it

is necessary to have a 10° downward bevel on the

bottom of the gullet that forces the chips into the

path of the top plate for removal.

Clearance Angle: the clearance angle (see

figure 19) is the amount that the top plate angles

down from the leading edge to the rear of the cut-

ter link. this clearance angle allows the cutter link

to pivot up into the wood and then down again

(refer to How the Chain Cuts in the next section

for more information).

Depth gauge: the depth gauge (see figure 19)

is a critical element of the cutter link and is often

overlooked in chain saw sharpening. the height

of the depth gauge must be below the leading

edge of the top plate by the correct amount for

your chain saw. refer to How the Chain Cuts in

the next section and Depth gauge Setting on

Page 28 to better understand the purpose of the

depth gauge.

Left- & Right-Hand Cutters: Chain saws have

left- and right-hand cutter links that together make

the cut. the sharpener must be set up differently

when sharpening left- and right-hand cutters (see

figure 20) because the angles on the cutters are

reversed. it is important to clearly identify the ori-

entation of the cutter before sharpening it.

after sharpening the cutter, always remember to

check, and if necessary, adjust the depth gauge

setting.

the depth gauge setting determines how big of a

bite the cutter takes ("2–3"). it is imperative that

the depth gauge is set below the leading edge

of the top plate by the proper amount so that the

cutter can move into the wood.

How the Chain Cuts

as illustrated in figure 21 below, when the cutting

point at the top of the cutter moves against the

wood ("1"), the front of the cutter pivots up until the

depth gauge meets the wood ("2"), which forces

the cutter to pivot even farther into the wood ("3")

to make the cut.

if the depth gauge is too high or too low, it will

prevent the cutter from pivoting forward and self-

feeding into the wood. refer to Depth gauge

Setting on Page 28 for additional information.

When the rear of the top plate meets the wood

("4"), it forces the cutter to continue pivoting for-

ward and move out of the kerf, producing wood

chips which are carried away by the top plate

angle in the final position ("5") to complete the

cut.

also important is the amount of the clearance

angle. the downward slope of the top plate

enables the cutter to move into the wood ("2")

and then forces it out again ("3–4") to complete

the cut.

always use the chain manufacturer's specifica-

tions for the cutter specifications when sharpen-

ing the chain.

the goal of this rocking motion is to allow the

chain saw to self-feed into the wood and do the

work without requiring the operator to force the

chain into the wood. this makes the job easier

and reduces wear on the saw and chain.

figure 23, gently tap the wheel with a non-

metallic object, such as a screwdriver handle

or wooden mallet.

Wheel Inspection &

Ring Test

do not assume that a grinding wheel is in sound

condition just because it is new or looks okay.

often damage can occur in shipping, with age,

or with exposure to moisture, and may not be

visible. inspect every wheel for damage before

installation.

First, do a visual inspection. look for any cracks,

chips, nicks or dents in the surface of the wheel. if

you see any of these, do not use the wheel.

second, do a ring test. this test will give you an

indication of any internal damage that may not be

obvious during a visual inspection. if the wheel

does not pass the ring test, do not use the

wheel.

figure 23. tapping locations for a ring test.

4. an undamaged wheel will emit a clear metal-

lic ring or “ping” sound in each of the four

spots. a damaged wheel will respond with a

dull thud that has no clear tone.

To perform a ring test:

1. make sure the wheel that you test is clean and

dry—otherwise, you may get false results.

—if you determine from the results of the ring

test that the wheel is damaged, do not

usE it!

2. if size permits, balance the wheel with your

finger in the center hole. if this is not possible,

hang the wheel in the air with a piece of cord

or string looped through the bore.

5. read and understand all the safety instruc-

tions listed in the beginning of this manual

and included with the chain saw owner's

manual.

Operation

in the following sharpening procedure, you adjust

the sharpener settings to grind the correct angles

for the chain, then sharpen each cutter link one

at a time.

6. make sure the sharpener is firmly secured to

the workbench.

7. select and test the grinding wheel that is right

for your chain, as instructed in the Wheel

Inspection & Ring Test procedure on Page

21.

after properly sharpening all of the cutter links,

you need to check, and if necessary, adjust the

depth gauge setting—the distance between the

top plate leading edge and the top of the depth

gauge. Even though the cutter may be properly

sharpened, if the depth gauge setting is not cor-

rect, the chain will not effectively cut the wood.

8. after successful completion of Step 7, install

the grinding wheel onto the sharpener, as

instructed in the Installing grinding Wheel

procedure on Page 14.

the t23108 is not designed to adjust the depth

gauge setting, and it is beyond the scope of this

manual to explain the many methods to perform

this important task (refer to Depth gauge Setting

on Page 28 for additional information).

NOTICE

Always refer to the chain manufacturer's

specifications when setting up the sharp-

ener. However, if this information is not

available, use the chart in Figure 22 on

Page 20 as a general guide.

To sharpen the chain cutters:

1. Clean the chain with a non-flammable clean-

er to remove any oil, dirt, and grime, then use

compressed air to thoroughly dry the chain.

Note: The following instructions begin by

sharpening the right-hand cutters. If you

choose to start with left-hand cutters, keep in

mind the chain holder rotation angle and, if

used, chain holder tilt will be different.

2. Visually inspect the chain and replace any

severely damaged links that could break

apart during sharpening. if replacement is not

possible, use a different chain.

9. rotate the chain holder counterclockwise

(looking down on it) and align it with the cor-

rect rotation angle mark on the scale for the

chain, as instructed in the Top Plate Angle

procedure on Page 22. this setting deter-

mines the top plate angle.

3. make sure all of the cutter top plates will be at

least ¹⁄4" in length after the sharpening proce-

dure is completed. this is the recommended

minimum top plate length to avoid the cutter

link from breaking apart during cutting opera-

tion.

10. if required for your chain, set the grinding

wheel tilt to provide the correct gullet angle,

as instructed in the gullet Angle procedure

on Page 24.

—if you suspect that any cutter top plate will

be shorter than ⁄4" in length after being

sharpened, replace that link or replace the

chain.

13. position the edge of the advancement guide

behind the cutter to be sharpened, then pull

the chain to the left until the guide catches

and stops the chain (see figure 32).

If the grinding wheel should break apart

link is under the grinding wheel. this will be

the first link sharpened.

—if the wheel matches the gullet profile and is

against the top and side plates when com-

pletely lowered, the advancement guide is

properly set for now. tighten the knob lock

nut on the adjustment controls behind the

guide to secure the setting.

use chalk or a marker to note the first link to

be sharpened so that you will know when you

are finished with that side of cutters.

Note: If all of the top plates are approximately

the same length, then start with any cutter.

The concern is that all top plates are the

same length when the sharpening operation

is complete to ensure they cut away the same

amount during operation.

—if the wheel hits the top plate or depth

gauge and does not completely lower into

the gullet, or it is not against the top and

side plates, adjust the advancement guide

until it successfully stops the chain in the

proper position. Be sure to secure the set-

ting by tightening the knob lock nut.

and sharpen angles that may be worn or

damaged. Do not make the gullet any deeper

than is necessary to accomplish this.

25. release the chain from the clamp plates, turn

it around 180° so that the cutters on the other

side of the chain are ready for sharpening.

26. rotate the chain holder to align with the angle

marks on the other side of the rotation scale,

and, if the chain requires a gullet angle, tilt

the chain holder 10° in the opposite direc-

tion.

Also, taking deep cuts with the grinding wheel

could burn the metal, which will damage

the temper of the steel. Chain cutters that

are heated excessively during sharpening

become brittle and dull quickly.

27. When you are satisfied that the sharpener

settings are correct, repeat Steps 18–23

for the rest of the cutters on that side of the

chain.

It is better to make a few light passes than

one deep one!

17. Back the depth knob bolt away from the depth

stop by a small amount, then thread the knob

28. Check, and if necessary, adjust the height of

the depth gauges. refer to the next subsec-

tion for more information.

18. adjust the advancement guide so that the

chain moves slightly to the right. this will

remove a small amount from the top and side

plates and provide the sharpened angles.

29. Clean and lubricate the chain per the manu-

facturer's recommendation before re-install-

ing it onto the chain saw.

Note: This critical adjustment is a matter of

trial-and-error and experience.

19. Connect the sharpener to power and wait for

the wheel to come to full speed.

For optimum performance from your machine,

follow this maintenance schedule and refer to any

specific instructions given in this section.

figure 36. grinding wheel edge profile.

With use, the abrasive surface of the grinding

wheel becomes embedded with material from the

chain, which reduces its effectiveness. in addi-

tion, the side and bottom edge deform and fails

to effectively sharpen the cutter edges. When this

happens, the sharpened surfaces become burned

or discolored, instead of having a clean, silver fin-

ish. additionally, the angles will not be properly

sharpened.

Cleaning

Cleaning the model t23108 is relatively easy.

disconnect the machine from power and wipe

down the surfaces with a damp shop rag, then dry

them with a clean, dry cloth.

use the included wheel dressing block to expose

a new abrasive surface on the wheel and to re-

form the side and edge profiles.

Lubrication

there are not any parts on this sharpener that

require lubrication by the end user.

the bearings of the sharpener motor were lubri-

cated and permanently sealed at the factory and

do not need any further attention unless they

need replacement.
