CHECK CHAIN
S HARPNESS
A sharp chain makes wood chips. A dull
chain makes a sawdust powder and
cuts slowly. See CHAIN SHARPENING in
the SERVICE AND ADJUSTMENTS sec-
tion.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw outs to one side or at an angle.
• Saw has to be forced through the
cut.
• Inadequate
supply of oil to the bar
and chain.
Check the condition of the guide bar be-
fore each use and each time the chain
is sharpened.
A worn guide bar will
damage the chain and make cutting diffi-
cult.
After each use, with unit disconnected
from power source, clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
• Disconnect
the chain saw from the
power source.
• Firstly remove screw. Loosen knob
slightly by turning
knob counter-clo-
ckwise and then turn the chain ten-
sion ring counter-clockwise
to relief
chain tension.
To remove the spro-
cket cover, trun knob counter-clock-
wise. Remove bar and chain from
saw.
• Clean the oil holes and bar groove
after each 5 hours of operation.
• Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
• When rail top is uneven, use a flat
file to restore square edges and
sides.
