To tension the chain
WARNING: A saw chain with an incorrect
tension can derail from the guide bar and
cause serious injury or death.
A saw chain becomes longer when you use it. Adjust the
saw chain regularly.
1. Loosen the bar nut that hold the clutch cover/chain
brake. Use a wrench.
2. Tighten the bar nuts by hand as tightly as you can.
3. Lift the front of the guide bar and turn the chain
tensioning screw. Use a wrench.
4. Tighten the saw chain until it is tight against the
guide bar but still can move easily.
5. Tighten the bar nuts using the wrench and lift the
front of the guide bar at the same time.

6. Make sure you can pull the saw chain around freely
by hand and that it does not hang from the guide
bar.
To lubricate the cutting equipment
Chain oil
WARNING: Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
•
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.
•
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.
•
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.
To check the chain lubrication
1. 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 75% throttle you should see a distinct line of oil on
the light surface.
