SAFETY INSTRUCTIONS

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.

•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 service agent.

Lubricating the bar tip sprocket

Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease.

Needle bearing lubrication

The clutch drum is fitted with one of the following drive sprockets:

ASpur sprocket (the chain sprocket is welded on the drum)

BRim sprocket (replaceable)

Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil.

Checking wear on cutting equipment

Check the chain daily for:

•Visible cracks in rivets and links.

•Whether the chain is stiff.

•Whether rivets and links are badly worn.
