SAFETY INSTRUCTIONS

1Undo the bar nuts that

hold the clutch cover and chain brake, using the combination spanner. Then tighten the nuts by hand as tight as you can.

2 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 not hang slack on the underside of the bar.

3 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 is not slack on the bottom of the bar.

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

4 Lubricating cutting equipment

Poor lubrication of cutting equipment may cause the chain to snap and lead to serious, even fatal injuries.

A Chain oil

•Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather.

•As a chainsaw 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 saw and the environment.

BFilling with chain oil

• 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 saw 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 carburetor as recommended (a weak mixture may mean that the fuel lasts longer than the oil). You should also use the recommended cutting equipment (a bar that is too long will use more chain oil). The above conditions also apply to models with an adjustable oil pump.
