Periodic
care
and
maintenance
(cont.)
5. SPARK PLUG:
Check
for carbon, fouling and cracks.
Keep
clean and
adjust
spark
plug gap to .025
inch.
6.
MAGNETO:
Do not
inspect
or
adjust
unless absolutely necessary.
The quantity
of
spark from the spark plug
will
indicate magneto condition. Breaker
point
gap
should be .020 inch. In event of removal all magneto parts must be replaced in
correct setting and location.
It is recommended that if magneto service work is
required, the chain saw be taken to your
local
servicing dealer (figure 12).
7.
CARBURETOR:
Do not screw adjustments
in too tight.
Remove the pump
base
portion for inspection and cleaning (figure 11). It is recommended that carburetor
overhaul
should be performed
by your servicing
dealer.
8. CLUTCH:
The clutch is
automatic,
designed to apply at a predetermined
motor
speed.
Do not slip clutch through
overloading as it
will
wear out lining.
Im-
mediately release the throttle
if chain is pinched.
9. OUTTER BAR: Make sure the bar is clean at
all
times to
assure
sufficient chain
lubrication
(figure 13).
Check the cutter bar for wear at regular
intervals
and
turn it over from time to time to
make sure
the wear is distributed
evenly. As
wear takes place, a sharp edge is left on the extreme edge of the groove and this
should be removed with a file
. . .
Care must be exercised in servicing bar to
prevent damage to chain groove. Use Bar Gauge No. 426235.
