C Checking chain lubrication
• Check the chain lubrication
each time you refuel.
Aim the tip of the saw at a
light coloured surface about
20 cm away. After 1 minute
running at 3/4 throttle you
should see a distinct line of
oil on the light surface.
If the chain lubrication is not working:
1 Check that the oil channel
in the bar is not
obstructed. Clean if
necessary.
2 Check that the groove in
the edge of the bar is
clean. Clean if necessary.
3 Check that the bar tip
sprocket turns freely and
that the lubricating hole in
the tip is not blocked.
Clean and lubricate if
necessary.
If the chain lubrication
system is still not working
after carrying out the
above measures you
should
contact your
service agent.
D Lubricating the bar tip sprocket
• Lubricate the bar tip
sprocket each time you
refuel. Use the special
grease gun and a good
quality bearing grease.
SAFETY INSTRUCTIONS
E Lubricating the clutch drum bearing
• Between the engine drive
shaft and the clutch drum is
a needle bearing that must
be lubricated daily. Use the
specially designed grease
gun and a good quality
bearing grease.
F Checking wear on cutting equipment
Saw chain
Check the saw chain daily for:
• Visible cracks in rivets and
links.
• Whether the chain is stiff.
• Whether rivets and links are
badly worn.
We recommend you
compare the existing chain
with a new chain to decide
how badly it is worn.
When the length of the
cutting teeth has worn down
to only 4 mm the chain must
be replaced.
G Chain drive sprocket
The clutch drum is fitted with one of the following drive
sprockets:
A SPUR (integral drive
sprocket)
B RING (replaceable)
Regularly check the
degree of wear on the
drive sprocket. Replace if
wear is excessive.
Replace the drive
sprocket whenever you
replace the chain.
