12.2 Insufficient chain lubrication
If after running the chain saw for about 20 minutes only a little lubricating oil has left the
container, the cause may be blockage of the oil duct (8) in the saw and/or the oil hole (16) in
the guide bar. If so, they should be cleaned.
To clean the oil duct (8) the cover plate (7) can be removed, if necessary, after unscrewing its
fastening screw.
12.3 To carry the chain saw
After use, the guide bar and chain should be covered with the chain guard that is supplied with
the tool.
12.4 Saw chains
Working with a blunt saw chain causes the chain, guide bar and drive sprocket to wear rapidly
and may even lead to the chain breaking and so it is important that the saw chain be
sharpened in good time.
It is advisable to have the chain be re-sharpened by a competent workshop.
The relevant angles on the saw-chain cutters are:
side-plate filing angle 85°
top-plate cuffing angle 60°
top-plate angle 30°
A 4 mm dia. round file should be used for sharpening the chain.
12.5 Guide bar
A small amount of ball-bearing grease should be fed occasionally with a grease gun through
the grease holes situated near the four rivets holding the nose sprocket on the guide bar.
The bottom edge of the bar is exposed to relatively heavy wear and so the bar should be
turned top to bottom whenever the chain is sharpened and at the same time the groove in the
bar and the oil holes (16) should be cleaned.
12.6 Drive sprocket
If the teeth of the drive sprocket (13) show any signs of wear. the sprocket should be replaced.
The drive sprocket should be changed with every second replacement of the chain.
12.7 Carbon brushes
When the chain saw's brushes are worn beyond a certain limit, a tripping device in the
brushes automatically stops the motor.
The brushes should be replaced by a specialist who has the right equipment. The saw can
then be given a thorough inspection at the same time and the motor be cleaned.
