Disconnect the ignition cable (D) from the spark plug by
pulling and twisting it simultaneously (Fig. 32).

Remove the spark plug using a spark plug wrench. DO NOT
USE ANY OTHER TOOLS.
5
Clean the spark plug with a copper wire brush or fit a
new one.
Carburetor setting
The carburetor 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.
Chain bar maintenance
Regular lubrication of the chain bar (guide rail for the chain and
teeth) is essential. The chain bar needs the maintenance
described in the following section in order for the saw to work
at an optimum level of performance.
Caution:
The sprocket tip on your new saw has been
pre-lubricated at the factory. Failure to lubricate 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 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 .34).
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.
