Table of Contents
Keep cutting equipment well lubricated and properly
maintained! A poorly lubricated chain is more likely to
break and lead to increased wear on the bar, chain and
drive sprocket.
WARNING! Never use a machine with faulty
safety equipment. The machine's safety
equipment must be checked and maintained
as described in this section. If your machine
fails any of these checks contact your
service agent to get it repaired.
WARNING! Always stop the engine before
doing any work on the cutting attachment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.
Specification of bar and saw chain
When the cutting attachment supplied with your machine has
to be replaced, because it is worn out or damaged, you must
only fit the types of bar and saw chain recommended by us.
Length (inches/cm)
Number of teeth on bar tip sprocket (T). Small number =
small tip radius = low risk of kickback.
Chain pitch (inches). The spacing between the drive links
of the chain must match the spacing of the teeth on the
bar tip sprocket and drive sprocket.
Number of drive links. The number of drive links is
determined by the length of the bar, the chain pitch and
the number of teeth on the bar tip sprocket.
Bar groove width (inches/mm). The groove in the bar must
match the width of the chain drive links.
Saw chain oil hole and hole for chain tensioner pin.
Saw chain pitch (inches). (The distance between three
drive links, divided by two.)
Drive link width (mm/inches)
Number of drive links.

WARNING! The risk of kickback is increased
with a badly sharpened chain!
General information on sharpening cutting teeth
Never use a blunt chain. When the chain is blunt you have
to exert more pressure to force the bar through the wood
and the cuttings will be very small. If the chain is very blunt
it will not produce any cuttings at all. Wood powder would
be the only result.
A sharp chain eats its way through the wood and
produces long, thick cuttings.
