5. With the spark plug removed, the
choke control pushed in and the
ignition control in the “OFF”
position, clear any excess fuel in
the engine by rapidly and repeat-
edly pulling the starter until no
evidence of fuel is seen escaping
from the spark plug opening.
6. Replace the spark plug and install
the spark plug lead and access
cover.
7. Refer to the Engine Start and Stop
section and follow the instructions
for starting a warm engine.
8. If the engine still fails to start,
refer to the Troubleshooting
Section.
If the carburetor choke is closed
(choke control fully extended) and
after repeated attempts, the engine
fails to start, the engine may be
flooded with fuel. The following steps
are recommended to clear a flooded
engine.
The ignition switch must be in the
“OFF” position to prevent the chance
of igniting fuel and/or fuel vapors
escaping from the engine during this
procedure.
2. Push the choke control completely
in to open the choke.
3. Remove the spark plug access
cover and disconnect the plug
wire. Remove the spark plug using
the scrench supplied with the
chain saw or other suitable tool.
4. Inspect the spark plug for damage
or excessive wear and replace if
necessary. If the spark plug
electrode is fuel soaked, or coated
with carbon deposits, clean and
set the plug gap. Refer to page 16
of this manual in the maintenance
section for spark plug information.

䡵
Use two cuts when bucking the
outboard end of an unsupported
log. Your first cut should be an
underbuck, cutting upward
through approximately 1/3 the
diameter of the tree. Finally, move
to the top of the log and finish the
cut by bucking down
(overbucking) to your first cut.
Limbing
Limbing a standing tree is usually
accomplished in the same manner as
bucking, with a third and final cut
used to remove the remaining stub of
the limb.
NOTE:
When cutting unsupported logs or limbs,
starting with an underbuck cut will minimize
the possibility of the wood splitting during
the bucking cut.
First Cut (underbuck)
About 1/3 of Tree Diameter
Second Cut (overbuck)
Bucking
Techniques
䡵
If the log is well supported, start
your cut from the top of the log.
Keeping the guide bar parallel to
the ground, cut straight down but
do not allow the saw to cut into
the ground.
䡵
Cutting downed timber, or "buck-
ing," increases the possibility of
the wood settling and pinching
the guide bar. Driving one or more
soft plastic or wooden bucking
wedges can help prevent bar-
pinching during a cut.
䡵
Use two cuts when bucking near
the inboard end of an unsup-
ported log.
1. Make the first cut as an overbuck
approx. 1/3 the diameter of the
log.
2. Finish the job with an underbuck
coming up from beneath and
joining the first cut.
WARNING!
Always cut downed timber from the
uphill side of the wood! Be alert for
potential injury from rolling or shifting
logs! Downed timber may shift or roll
unpredictably during cutting or
handling operations!
WARNING!
Kickback danger increases in over-
height or out of position cutting! Do
not overreach, or attempt to cut
above shoulder height!
