GENERAL SAFETY PRECAUTIONS
•
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 nut while
holding up the tip of the bar. Check that you can pull the
saw chain round freely by hand, and that there is no slack
on 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 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.

Filling with chain oil

All our chain saws have an automatic chain lubrication

The saw chain oil tank and the fuel tank are designed so
that the fuel runs out before the saw chain oil.
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).

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

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.

Check that the oil channel in the bar is not obstructed.

WARNING! Poor lubrication of cutting

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.
