Checking wear on cutting equipment
A. Saw chain
Check the saw chain daily
for:
• Visible cracks in rivets and
links.
• Whether the chain is stiff.
• Whether rivets and links
are badly worn.
Compare the existing chain
with a new chain to decide
how badly it is worn.
When the length of the
cutting teeth has worn down
to only 4 mm the chain must
be replaced.
SAFETY INSTRUCTIONS
C. Checking chain lubrication
• Check the chain
lubrication each time you
refuel.
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.
• Check that the oil channel
in the bar is not
obstructed. Clean if
necessary.
Check also that the O-
ring is in position and is
undamaged.
• 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 the
above measures you
should contact your
service agent.
Procedure if the lubrication does not
function:
min 4 mm
(0,16")
WARNING!
Using faulty cutting equipment may
increase the risk of accidents.
B. Chain drive wheel
D. Guide bar
Check regularly:
• Whether there are burrs
on the edges of the bar.
Remove these with a file if
necessary.
• Whether the groove in the
bar has become badly
worn. Replace the bar if
necessary.
• Whether the tip of the bar
is uneven or badly worn.
If a hollow forms on one
side of the bar tip this is
due to a slack chain.
• To prolong the life of the
bar you should turn it
over daily.
!
D. Adjusting chain lubrication
• When cutting dry or hard
species of wood it may be
necessary to increase
lubrication. To increase
the oil flow, first undo
screw (A) then turn the
adjuster screw (B)
anticlockwise. Re-tighten
screw (A). Remember that
this will increase the oil
consumption and you
should therefore check the
level in the oil tank more
frequently.
Check regularly the degree of
wear on the drive wheel.
Change if it is irregularly
worn.
A
B
C.Vibration damping
system
Check regularly that the
vibration damper i free from
cracks.
Check regularly the degree of
wear on the rubber elements.
Change if worn.
