SAFETY INSTRUCTIONS

C Checking chain lubrication

•Check the chain lubrication

each time you refuel.

Aim the tip of the saw at a light coloured surface about 20 cm 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:

E Lubricating the clutch drum bearing

•Between the engine drive shaft and the clutch drum is a needle bearing that must be lubricated daily. Use the specially designed grease gun and a good quality

bearing grease.

FChecking wear on cutting equipment

Saw chain

1Check that the oil channel in the bar is not obstructed. Clean if necessary.

2 Check that the groove in the edge of the bar is clean. Clean if necessary.

3 Check that the bar tip sprocket turns freely and that the lubricating hole in the tip is not blocked. Clean and lubricate if necessary.

Check the saw chain daily for:

•Visible cracks in rivets and links.

•Whether the chain is stiff.

•Whether rivets and links are badly worn.

We recommend you compare the existing chain with a new chain to decide how badly it is worn.

When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.

min 4 mm

(0,16")

If the chain lubrication system is still not working after carrying out the above measures you should contact your service agent.

D Lubricating the bar tip sprocket
