Chain oil
Chain oil
•
The chain lubrication system is automatic.
Always use special chain oil with good adhesive characteristics.
•
In countries where no special chain oil is available,
gear oil EP 90 may be used.
•
Never use waste oil. Doing so may result in damage to the chain,
bar and oil pump.
•
It is important to use oil of the correct viscosity appropriate to the air
temperature.
•
In temperatures below 0°C (32°F) some oils become more sluggish.
That puts an added strain on the oilpump and may cause damage
to oil pump parts.
•
Contact your service dealer for help in choosing the right chain oil.
Check that the chain brake is disengaged by moving the front
hand guard towards the front handle.
Take off the bar nuts and remove the clutch cover.
WARNING!
Always pull out the plug before fitting parts or adjusting the saw.
Wear gloves when working with the chain in order to protect
your hands from injury.
STOP
Fit the chain around guide bar nose with the top cutters facing
forwards. Holding the chain over the guide bar nose, position
the back end of the guide bar against the drive sprocket at a
45° angle to the power head. Pass the free end of the chain
around the drive sprocket, swing the guide bar into place over
the mounting bolt and against the power head, and guide the
chain into the guide bar groove.
Seat the guide bar on the adjusting pin and replace the clutch
cover. Check that the drive links fit correctly on the drive
sprocket and that the chain is in the groove on the bar.
Tighten bar nuts finger tight. Adjust chain tension, using
combination wrench to turn adjustment screw clockwise to
tighten. Tighten adjustment screw until the chain is drawn
snugly against the underside of the bar.
Support the tip of the bar while adjusting the chain. Chain tension
is correct when there is no slack on the underside of the bar, but
the chain may still be turned easily by hand. Hold up the bar tip
and tighten the bar nuts with the combination wrench.
When a new chain has been fitted, check tension frequently until
the chain has been broken in.
Check chain tension regularly. A chain that is correctly adjusted
gives good cutting performance and lasts longer.
