Chain Saw Maintenance
Do not use the chain saw with the
blunt or damaged chain. If high
pressure is required during operation
of the chain saw and sawdust is ne
instead of large chippings, check
whether the edge on the chain is
damaged. Grind the edge to keep the edge angle the same as that
of new product. The service life of the chain can be prolonged
by grinding the edge. Check whether the chain saw is damaged
or worn each time after fuel lling.
If the chain teeth are less than 4mm long as a result of wear,
replace the chain.
Grinding tools

The following tools are required to properly grind the chain.
A. Round le and clamp
B. Flat le
C. Depth gauge
Use the le (4.0mm round le) and clamp of appropriate
specifications to achieve good grinding effects.
Consult POWERKING for appropriate grinding tools and
specifications.

1. Fix the chain and push the hand guard forwards. Push the
hand guard in the opposite direction of the front handle to
rotate the chain.
2. The cutting edges for operation of the chain with the left
and right hand are distributed alternately. Grinding must
be done from inside to outside.
3. Keep the angle of the le clamp and the linear parallelism
of the chain location and le the back of the cutting edge
until the damaged part (lateral or top part) is ground.
4. Keep the le parallel.
5. Sharpen the seriously worn edge at rst, and then grind all
the edges to the same length.

1. The wood cutting thickness depends on the grinding
depth. Therefore, the chain must be properly maintained
during operation.
2. If the length of the cutting edge is reduced, the bottom
height must be reduced at the same time.
3. Use the depth gauge for positioning, and le the
protruding part.
4. Round the front part of the bottom to smooth the cutting
process.
