GENERAL SAFETY PRECAUTIONS • In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used. • Never use waste oil! This is dangerous for yourself, the machine and the environment. Filling with chain oil regularly. Turn the adjuster screw anticlockwise to decrease the oil flow. The oil pump is preset at the factory to satisfy most lubrication requirements. A full oil tank normally lasts about the same time as a full fuel tank. Therefore check the amount of oil in the oil tank when filling the fuel to prevent damage to the saw chain and bar that may arise due to a lack of lubrication. What to do if lubrication does not work: • Check that the oil channel in the bar is not obstructed. Clean if necessary. Checking chain lubrication • Check the chain lubrication each time you refuel. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface. • Check that the oil channel in the gear housing is clean. Clean if necessary. • Check that the bar tip sprocket turns freely. If the chain lubrication system is still not working after carrying out the above checks you should contact your service workshop.

GENERAL SAFETY PRECAUTIONS
14 – English
1153411-49 Rev. 8 2012-02-16
•
In areas where oil specifically for lubrication of saw
chains is unavailable, ordinary EP 90 transmission oil
may be used.
•
Never use waste oil!
This is dangerous for yourself,
the machine and the environment.
Filling with chain oil
The oil pump is preset at the factory to satisfy most
lubrication requirements. A full oil tank normally lasts
about the same time as a full fuel tank. Therefore check
the amount of oil in the oil tank when filling the fuel to
prevent damage to the saw chain and bar that may arise
due to a lack of lubrication.
Checking chain lubrication
•
Check the chain lubrication each time you refuel. Aim
the tip of the bar at a light coloured surface about 20
cm (8 inches) away. After 1 minute running at 3/4
throttle you should see a distinct line of oil on the light
surface.
Adjusting chain lubrication
When cutting dry or hard species of wood it may be
necessary to increase lubrication. Turn the adjuster screw
clockwise to increase the oil flow. Remember that this will
increase oil consumption, check the level in the oil tank
regularly. Turn the adjuster screw anticlockwise to
decrease the oil flow.
What to do if lubrication does not work:
•
Check that the oil channel in the bar is not obstructed.
Clean if necessary.
•
Check that the oil channel in the gear housing is
clean. Clean if necessary.
•
Check that the bar tip sprocket turns freely. If the chain
lubrication system is still not working after carrying out
the above checks you should contact your service
workshop.

Saw chain
Check the chain daily for:
•
Visible cracks in rivets and links.
•
Whether the chain is stiff.
