GENERAL SAFETY PRECAUTIONS
14 – English
Tensioning the chain
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.
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.
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.
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, with its vegetable oil base, is also 
biodegradable. 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!  Using waste oil can be dangerous 
to you and damage the machine and 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 saw chain oil tank and the fuel tank are designed 
so that the fuel runs out before the saw chain oil.
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).
!
WARNING! A slack chain may jump off 
and cause serious or even fatal injury.
!
WARNING! Poor lubrication of cutting 
equipment may cause the chain to snap, 
which could lead to serious, even fatal 
injuries.
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.
