To adjust the raker clearance you will need a flat file and a 
raker gauge.

•

Place the gauge over the raker lip.

•

Place the file over the part of the lip that protrudes through 
the gauge and file off the excess. The clearance is correct 
when you no longer feel any resistance as you draw the 
file over the gauge.

The more you use a chain the longer it becomes. It is 
therefore important to adjust the chain regularly to take up the 
slack.

Check the chain tension every time you refuel. NOTE! A new 
chain has a running-in period during which you should check 
the tension more frequently.

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

Tension the chain as tightly as possible, but not so tight that 
you cannot pull it round freely by hand.

•

Undo 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.

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.

•

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.
