MAINTENANCE
WARNING:
All maintenance work on the chainsaw apart from the work described

Chain brake operational test
Test the chain brake periodically to ensure proper function.
Perform a chain brake test prior to initial cutting, following extensive cutting, and definitely
following any Chain brake service.
Test chain brake as follows:
1. Place saw on a clear, firm, flat surface.
2. Start engine.
3. Grasp the rear handle (Fig 21-A) with your right
hand.
4. With your left hand, hold the front handle (Fig 21-
B) [not chain brake lever (Fig 21-C)] firmly.
5. Squeeze the throttle trigger to 1/3 throttle, then
immediately activate the chain brake lever (Fig 21-C).
6. Chain should stop abruptly. When it does, immedi-
ately release the throttle trigger.
7. If chain brake functions properly, turn the engine off and return the chain brake to the DIS-
ENGAGED position.

If chain does not stop, turn engine off and take your unit to the nearest
authorised service centre for service.

dirt will be drawn into engine and damage it. The air
filter must be cleaned after 20 hours of service.
