SAFETY INSTRUCTIONS

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.

Lubricating cutting equipment

WARNING! Poor lubrication of cutting

!equipment may cause the chain to snap, which could lead to serious, even fatal injuries.

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.

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.

Filling 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 engine 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 carburettor as recommended (a weak 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). The above conditions also apply to chain saw models with an adjustable oil pump.

Checking chain lubrication

•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 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.
