Sharpen cutters on one side of the chain first.
File from the inside of each cutter to the
outside. Then, turn the chain saw around and
repeat the process for the other side of the
chain.
File on the forward stroke only. Use 2 or 3
strokes per cutting edge.
Keep all cutters the same length when filing.
File enough to remove any damage to cutting
edges (side plate and top plate of cutter).
File chain to meet the specifications as
shown.
WARNING: Maintain the proper hook
angle according to the manufacturer’s
specifications for the chain you are
using. Improper hook angle will increase
the chance of kickback which can result
in serious injury.
4. Check and lower depth gauges.
Place gauge tool on cutter.
If the depth gauge is higher than the depth
gauge tool, file it level to the top of the depth
gauge tool.
Maintain rounded front corner of depth gauge
with a flat file.
NOTE: The very top of the depth gauge should
be flat with the front half rounded off with a flat
file.
GUIDE BAR
Conditions which require guide bar
maintenance:
Saw cuts to one side or at an angle.
Saw has to be forced through the cut.
Inadequate supply of oil to bar/chain.
Check the condition of guide bar each time
chain is sharpened. A worn guide bar will
damage the chain and make cutting difficult.
After each use, ensure ON/STOP switch is in
the STOP position, then clean all sawdust from
the guide bar and sprocket hole.
To maintain guide bar:
1. Move ON/STOP switch to STOP.
2. Loosen and remove bar nuts and clutch
cover. Remove bar and chain from saw.
3. Clean the oil holes (A) and bar groove (B).
4. Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
5. When rail top is uneven, use a flat file to
restore square edges and sides.
Replace guide bar when the groove is worn,
the guide bar is bent or cracked, or when
excess heating or burring of the rails occurs. If
replacement is necessary, use only the guide
bar specified for your saw in the repair parts list
or on the decal located on the chainsaw.
