Tools and Supplies Needed:
•
Chainsaw File Holder
•
5/32" Round Chainsaw File
•
Wire Brush
•
Depth Gauge jointer
•
Flat File
•
Safety Glasses
•
Gloves
Note:
Occasionally remove filing from the file with a wire brush.
1.
Position the File into a left hand cutter with the holder and file at a 30° angle
to the Bar (
Figure 29 and 30
).
2.
Keep the file level with the top plate of the tooth and do not let the file dip
or rock.
3.
Use light but firm pressure to stroke towards the front corner of the tooth
and lift file away from the steel on the return stroke.
4.
Sharpen every left hand tooth in the same direction.
5.
Move to the other side and file the right hand cutters in the opposite
direction remembering to lift file away from the steel on each return stroke.
Note:
Every time the chain is filed, check the depth gauge clearance with a depth
gauge Jointer. The depth gauge should be maintained at a clearance of .025
in. (0.6 mm) (
Figure 31
). Depth gauge jointers are available in .020 in. to
.035 in. (0.5 mm to 0.9 mm). Use a .025 in. (0.6 mm) depth gauge jointer.
6.
Position the Depth Gauge Jointer (
Figure 32
) onto the top of the cutters
with a Raker (Depth Gauge) in the slot at the end of the jointer.
7.
If the Raker is above the Jointer, use a flat file to adjust the Raker down to
be as close to level with top surface of the jointer without filing the Jointer.
Note:
Depth gauges must be adjusted with the flat file in the same direction the
adjoining cutter was filed with the round file. Use care not to contact cutter
face with the file when adjusting depth gauges.
8.
Check all remaining Rakers with the Depth Gauge Jointer and file as
needed.
9.
After lowering each depth gauge, restore original shape by rounding the
front. Be careful not to damage adjoining drive links with the edge of the file
(
Figure 33
).
