Turning the chain bar
The bar should be reversed every 8 working hours to ensure
uniform wear. Keep the bar groove and lubrication hole clean
using the bar groove cleaner supplied optional. (Fig. 35)
Check the bar rails frequently for wear and, if necessary,
remove the burs and square-up the rails using the flat file.
(Fig. 36)
Warning:
Never fit a new chain to a worn chain bar.

Oil passages
Oil passages on the bar should be cleaned to ensure proper
lubrication of the bar and chain during operation.
Note:
The condition of the oil passages can be easily checked.
If the passages are clear, the chain will automatically give off
a spray of oil within seconds of starting the saw. Your saw is
equipped with an automatic oiler system.
Automatic chain lubrication.
The chain saw is equipped with an automatic oil lubrication
system with a toothed wheel drive. It automatically supplies the
bar and the chain with the right quantity of oil. The moment
the engine is accelerated, the oil also starts to flow through the
bar plate more quickly as well.
The chain lubrication system has been set to its perfect
adjustment at the factory. If it requires adjusting, take the saw
to your nearest authorized after-sales service outlet.
A setting screw for adjusting the chain lubrication
(Fig. 37/ Item A) is located on the underside of the chain
saw. Turning the screw counter-clockwise increases the chain
lubrication, turning it clockwise decreases the chain lubrication.
To check the chain lubrication, hold the chain saw, with the
chain, over a piece of paper and run it at full speed for a few
seconds. You will be able to judge the set amount of oil from
the paper.
Chain maintenance
Chain sharpening
Chain sharpening requires special tools to ensure that cutters
are sharpened at the correct angle and depth. For the
inexperienced chain saw user, we recommend that the saw
chain be professionally sharpened by the nearest professional
Service Center. If you feel comfortable sharpening your own
saw chain, special tools are available from the professional
Service Center.
Chain sharpening (Fig. 38)
Sharpen the chain using protective gloves and a round file of
ø3/16” (4.8mm).
Always sharpen the cutters only with outward strokes (Fig. 38)
observing the values given in Fig. 39.
