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.
Bar
• 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.
• Lubrication hole and hole for the chain tensioner.
Chain
• Saw chain pitch (inches). (The distance between
three drive links, divided by two.)
• Drive link width (mm/inches)
• Number of drive links.
Sharpening your chain and adjusting
raker clearance
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.
• The cutting part of the chain is called the cutting link
and this consists of a cutting tooth (A) and the raker lip
(B). The cutting depth is determined by the difference
in height between the two.
• When you sharpen a cutting tooth there are five
important factors to remember.
!
WARNING! The risk of kickback is
increased with a badly sharpened chain!
