service.
1.
Set the On/Off switch to Stop (0)”.
2.
Remove the top cover (A) by undoing the cover
fastening screw (B) on the cover. You can then
remove the cover (Fig. 18A).
3.
Disconnect the ignition cable (D) from the spark
plug by pulling and twisting it simultaneously (Fig.
18B).
4.
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.
7.2.5 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.
7.2.6 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 (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 .20).
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. 21A)
Check the bar rails frequently for wear and, if
necessary, remove the burs and square-up the rails
using the flat file. (Fig. 21B)
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. 26/ 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.
