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.
