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:

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

E Needle bearing maintenance

A

The clutch drum is equipped with one of the following chain sprockets:

• Spur sprocket (A) (the chain sprocket is welded on the drum)

• Rim sprocket (B)

B

(exchangeable)

Both versions have built-in needle bearing at the drive shaft, whitch has to be greased regularly (once a week).

FChecking wear on cutting equipment

Saw chain

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.

If the chain lubrication system is still not working after carrying out the above measures you

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.
