•

Loosen the bar nuts that hold the clutch cover/chain brake. 
Use the combination spanner. Then tighten the bar nuts 
by hand as tight as you can.

•

Raise the tip of the bar and stretch the chain by tightening 
the chain tensioning screw using the combination 
spanner. Tighten the chain until it does not sag from the 
underside of the bar.

•

Use the combination spanner to tighten the bar nuts while 
lifting the tip of the bar at the same time. Check that you 
can pull the chain round freely by hand and that it does not 
sag from the underside of the bar.

The position of the chain tensioning screw on our chain saws 
varies from model to model. See instructions under the 
heading What is what? to find out where it is on your model.

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.

Never use waste oil!  This is dangerous for yourself, the 
machine and the environment.

•

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 carburetor as recommended 
(a lean 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).

•

Check the chain lubrication each time you refuel. See 
instructions under the heading Lubricating the bar tip 
sprocket.

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.

IMPORTANT! When using vegetable based saw chain oil, 
dismantle and clean the groove in the bar and saw chain 
before long-term storage. Otherwise there is a risk of the 
saw chain oil oxidizing, which will result in the saw chain 
becoming stiff and the bar tip sprocket jamming.
