SAFETY INSTRUCTIONS
D. Correction of raker clearance
Chain lubrication
WARNING!
A slack chain may jump off and cause
serious or even fatal injury.
A. Checking
• Check the chain
lubrication each time the
petrol is replenished.
Aim the tip of the saw at a
light coloured surface
about 20 cm away. After 1
minute running at 3/4
throttle you should see a
distinct line of oil on the
light surface.
The oil flow can be
regulated with the screw
(A) on the hydraulic
motor.
Turn the screw anti-
clockwise to increase the
flow.
• The more you use a
chain the longer it
becomes. It is therefore
important to adjust the
chain regularly to take
up the slack.
• Check the chain tension
every time you refuel.
NOTE! A new saw chain
has a running-in period
during which you should
check the tension more
frequently.
• Tension the chain as
tightly as possible, but
not so tight that you
cannot pull it round
freely by hand.
Tensioning the saw chain
• When correction of the
raker clearance is made
the teeth must be newly
sharpened.
We recommend that you
adjust the raker clearance
every third time you
sharpen the chain.
NOTE! This
recommendation
assumes that the length
of the cutting teeth is not
reduced excessively.
• A FLAT FILE and an
RAKER CLEARANCE
GAUGE are required to
correct the raker
clearance.
• Place the gauge over the
raker lip.
• Place the file over the
part of the lip that
protrudes through the
gauge and file off the
excess. The clearance is
correct when you no
longer feel any resistance
as you draw the file over
the gauge.
