Before filing:
1. Make sure the saw chain is held securely.
2. Make sure the engine is stopped.
3. Use a round file with the proper size for your chain.
Note:
Chain type: Oregon 91PJ063X. File size: 5/32 in (4mm).
Place your file on the cutter and push straight forward. Place the file in position, as
illustrated.
After every cutter has been set, check the depth gauge and file it to the proper level, as
illustrated.
Make sure every cutter has the same length and angle, as illustrated.
Chain bar
1. Reverse the bar occasionally to prevent partial wear.
2. The bar rail should always have parallel internal faces (see diagram). Check for wear
of the bar rail by applying a ruler to the bar and the outside of a cutter. If a gap is
observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar
needs to be corrected or replaced.
Storage
Store the chainsaw after emptying the lubrication tank and fuel tank. Allow the engine to
cool before storing in any enclosure.
To reduce the fire hazard, keep the engine, silencer and petrol storage area free of hedge,
leaves, or excessive grease.
Troubleshooting
WARNING!
Always switch off the engine and pull the ignition cable before starting any
inspection or adjustment work.
If after making an adjustment or repair to the engine you let it run for a few
minutes, remember that the exhaust and other parts will get hot. Thus, do not
touch parts that emanate heat, as these may burn you.
