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.
Adjusting chain lubrication
When cutting dry or hard species of wood it may be
necessary to increase lubrication. Turn the adjuster screw
clockwise to increase the oil flow. Remember that this will
increase oil consumption, check the level in the oil tank
regularly. Turn the adjuster screw anticlockwise 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
GENERAL SAFETY PRECAUTIONS
the above checks you should contact your service
workshop.
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.
