the guide bar sprocket tip as explained below will
result in poor performance and seizure, voiding the
manufacturer's warranty.
Tools for lubrication
The Lube Gun (optional) is recommended for
applying grease to the guide bar sprocket tip. The
Lube Gun is equipped with a needle nose tip which is
necessary for the efficient application of grease to the
sprocket tip.
To lubricate sprocket tip
Lubrication of the sprocket tip is recommended after
10 hours of use or once a week, which ever occurs
first. Always thoroughly clean guide bar sprocket tip
before lubrication.
Note: The saw chain does not have to be removed in
order to lubricate the teeth of the chain bar.
Lubrication is possible during work, with the engine
switched off.
Warning: Wear heavy duty work gloves when
handling the bar and chain.
1. Set the On/Off switch to Stop (0)".
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (optional), insert needle nose
into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig .22).
4. Rotate saw chain by hand. Repeat lubrication
procedure until the entire sprocket tip has been
greased.
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the
saw with chain that is TOO TIGHT will contribute to
rapid bar wear.
To help minimize bar wear, the following guide bar
maintenance procedures are recommended.
Warning: Always wear protective gloves during
maintenance operations. Do not carry out
maintenance when the engine is hot.
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. 23A)
Check the bar rails frequently for wear and, if
necessary, remove the burs and square-up the rails
using the flat file. (Fig. 23B)
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 oiler
Your chain saw is equipped with an automatic gear
driven oiler system. The oiler automatically delivers
the proper amount of oil to the bar and chain. As the
engine speed increases, so does the oil flow to the
bar pad. There is no flow adjustment. The oil reservoir
will run out at approximately the same time as the fuel
supply runs out.
9.8 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. 24)
Sharpen the chain using protective gloves and a
round file of ø3/16" (4.8mm).
Always sharpen the cutters only with outward strokes
(Fig. 25) observing the values given in Fig. 24.
After sharpening, the cutting links must all have the
same width and length.
Warning: A sharp chain produces well-defined
chips. When your chain starts to produce sawdust, it
is time to sharpen.
After the blades have been sharpened 3-4 times,
check the height of the depth limiter and if necessary
lower it with a flat file and then round off the front
corner (Fig. 26).
Chain tension
Check the chain tension frequently and adjust as
often as necessary to keep the chain snug on the bar,
but loose enough to be pulled around by hand. (see
also point 5.3)
