Adjusting chain lubrication
When cutting dry or hard species of wood it may be
necessary to increase lubrication. Turn the adjuster screw
anticlockwise to increase the oil flow. Remember that this
will increase oil consumption, check the level in the oil
tank regularly. Turn the adjuster screw clockwise to
decrease the oil flow.
What to do if lubrication does not work:
• Check that the oil channels in the bar are not
obstructed. Clean if necessary.
• Check that the oil channel in the gear housing is
clean. Clean if necessary.
• Check that the bar tip sprocket turns freely. If the chain
lubrication system is still not working after carrying out
the above checks you should contact your service
workshop.
GENERAL SAFETY PRECAUTIONS
Checking wear on cutting equipment
Saw chain
Check the 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 the existing chain is worn.
When the length of the cutting teeth has worn down to
only 5/32 inch (4 mm) the chain must be replaced.
Chain drive sprocket
Regularly check the degree of wear on the drive sprocket.
Replace if wear is excessive.
Guide bar
Check regularly:
• Whether there are burrs on the edges of the bar.
Remove these with a file if necessary.
• Whether the groove in the bar has become badly
worn. Replace the bar if necessary.
