GENERAL SAFETY PRECAUTIONS
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 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! Using waste oil can be dangerous to you and damage the machine and environment.
IMPORTANT! When using vegetable based saw chain oil, dismantle and clean the groove in the bar and saw chain before
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).
Checking chain lubrication
•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.
•Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.
Chain drive sprocket
The clutch drum is fitted with one of the following drive sprockets:
