SAFETY INSTRUCTIONS
Lubricating cutting equipment
Chain oil
Chain oil must demonstrate good adhesion to the chain and
also maintain its flow characteristics regardless of whether it
is warm summer or cold winter weather.
As a chain saw manufacturer we have developed an optimal
chain oil which has a vegetable oil base. We recommend the
use of our own oil for both maximum chain life and to minimise
environmental damage. If our own chain oil is not available,
standard chain oil is recommended.
In areas where oil specifically for lubrication of saw chains is
unavailable, ordinary EP 90 transmission oil may be used.
Never use waste oil! This is dangerous for yourself, the
machine and the environment.
Filling with chain oil
• All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also adjustable.
• The sizes of the chain oil tank and fuel tank have been
chosen so that the engine will run out of fuel before
running out of oil. This means that you should never run
with a dry chain.
However, this safety feature requires that you use the right
sort of chain oil (if the oil is too thin it will run out before the
fuel), and that you adjust the carburettor as recommended
(a weak mixture may mean that the fuel lasts longer than
the oil) and that you also use the recommended cutting
equipment (a bar that is too long will use more chain oil).
The above conditions also apply to chain saw models with
an adjustable oil pump.
Checking chain lubrication
• Check the chain lubrication each time you refuel.
Aim the tip of the bar at a light coloured surface about 20
cm (8 inches) 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:
• Check that the oil channel in the bar is not obstructed.
Clean if necessary.
• Check that the groove in the edge of the bar is clean.
Clean if necessary.
• Check that the bar tip sprocket turns freely and that the
lubricating hole in the tip sprocket is not blocked. Clean
and lubricate if necessary.
If the chain lubrication system is still not working after carrying
out the above checks and associated measures you should
contact your service agent.
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.
Needle bearing lubrication
The clutch drum is fitted with one of the following drive
sprockets:
A Spur sprocket (the chain sprocket is welded on the drum)
B Rim sprocket (replaceable)
Both versions have a needle bearing on the drive shaft, which
has to be greased regularly (once a week). CAUTION! Use
only high quality bearing grease or engine oil.
!
WARNING! Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
