Sharpening
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.
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.
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).
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.
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.
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.
— If you suspect that any cutter top plate will
be shorter than
1
⁄
4
" in length after being
sharpened, replace that link or replace the
chain.
4. DISCONNECT MACHINE FROM POWER!
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.
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.
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.
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.
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.
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.
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.
