b. For a warm engine:
IJLeave choke lever in off position. Figure 14.
2. ) Pull the starter rope quickly with your right
hand until the engine starts. Figure 15 .
3. ) Stop the engine by moving the Start/Stop
Switch to the “Stop” position. Figure 14 .
c. For a refueled warm engine after running
out of fuel:
1. ) PuU the choke lever to full choke. Figure 14.
2. ) Pull the starter rope quickly with your right
hand until the engine attempts to start.
3. ) Push the choke lever to off. FHgure 14.
4. ) Pull the starter rope quickly with your right
hand imtil the engine starts. Figure 15.
3. IMPOIOVUilT POINTS TO №MEMBER
a. When pulling the starter rope, do not use the
full ^ent of the rope as this can cause the rope to
break. Do not let the starter rope snap back—
hold the handle and let the rope rewind slowly.
b. If the engine floods, let the unit sit for a few
minutes, then repeat starting procedure using the
half-choke position.
c. For cold weather starting, allow the engine to
warm up (1-2 min.) at the half-^hoke position,
then move choke to the“Off” position. Do not cut
material with choke at “Full” or “Half” position.
TYPES OF CUTTING
a.

c.
A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
Cut wood only. Do not cut metal* plastics; ma­
sonry; non-wood building materials; etc.
Stop the saw if the chain strikes a foreign
object. Inspect the saw ^d repair or replace
p^s as necessary.
Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain and
thus increase the possibility of kickback.
A WARNING
Kickback can occur when the moving chain con­
tacts an object at the upper portion of the tip of the
guide bar or when the wood closes in and pinches
the saw chsw in the cut. Cont
tion of the tip of the guide bar can cause the chai
to dig into the object and stop the chain for an in­
stant. The result is a lightning fast, reverse reac­
tion which kicks the guide bar up and back toward
the operaton If the saw chain is pinched along the
tpp of the guide bar, the guide oar can be drivjen
rapidly back toward ike operaton Either of these
reactions can cause loss of saw control which can
result in serious injury,_________________________

2. UNDERSTANDm FORCES
Pinch-kickback and Pull-In occur when the
chain is suddenly stopped by being pinched,
caught, or by contacting a foreign object in
the wood. This stopping of the chain results in a re­
versal of the chain force used to cut wood and causes
the sawto move in the opposite direction of chain ro­
tation. Either reaction can result in loss of control
and possible serious injuiy.
• Pinch-Kickback—
occurs when the chain on top of the bar is sudden­
ly stopped.
— rapidly drives saw straight back toward operator
• PuU-In~
— occurs Tiriien the chain on the bottom of the bar is
suddenly stopped.
— pulls the saw rapidly forward.
3. PROCEDURE
Practice cutting a few small logs using the following
technique to get the “feel” of using your saw before
you begin a m^'or sawing operation.
a. Accelerate engine to full throttle before
entering cut by squeezing the throttle trigger.
b. Begin cutting with the saw frame against
the lo^ Figure 16.
c. Keep the engine at full throttle the entire
time you are cutting.
d. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, dam^
to the bar, chain, or engine can result.
e. Release the throttle trigger as soon as the
cut is completed, allowing the engine to idle. K
you run tiie saw at full throttle without a cutting
load, imnecessaiy wear can occur to the chain,
bar, and engine.
f To avoid losing control when cut is complete, do
not put pressure on saw at end of cut.
g. : Stop the engine before setting the saw down af­
ter cutting.

at all times.
Study the natural conditions that can cause
the tree to fall in a particular direction.
1.
) The WIND direction and speed.
2. ) The LEAN of the tree. The lean of a tree
might not be apparent due to uneven or slop-

ing tenain. Use a plumb or level to determine
the direction of tree lean.
3. ) WEIGHTED and BRANCHES on one side.
4. ) Surrounding TREES and OBSTACLES.
Look for decay and rot. If the tnink is rotted, it
can snap and fail toward the operator.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the
tree to fall. Maintain a distance of 2 1/2 tree
lengths from the nearest person or other objects.
Engine noise can drown out a warning call.
