WARNING!
Always ensure the pole saw head is
securely locked! Do not attempt to use the pole chain saw with
the head in any other position or unlocked!

WARNING!
Kickback may occur when the moving
chain contacts an object at the upper portion of the tip of the
guide bar or when the wood closes in and pinches the chain
saw in the cut (Fig. 21). Contact at the upper portion of the
tip of the guide bar can cause the chain to dig into the object
and stop the chain for an instant. The result is a lightning-
fast reverse reaction, which kicks the guide bar up and back
toward the operator. If the pole saw is pinched along the top
of the guide bar, the guide bar can be driven rapidly back
toward the operator. Either of these reactions can cause loss
of saw control, which can throw the operator off balance and
result in serious injury. Do not rely exclusively upon the safety
devices built into the saw. As a user, you should take several
precautions to keep your cutting jobs free from accident or
injury.
Proper Cutting Stance
• Balance your weight with both feet on solid ground.
• Your body should always be to the left of the chain line.
• The most typical cutting application is to position the
unit at an angle of 60° or less depending on the specific
situation (Fig. 22). As the angle of the pole chain saw shaft
to the ground increases, the difficulty of making the first
cut (from the underside of limb) increases.

Basic Cutting Procedure
This unit is designed for trimming small branches and limbs
up to recommended 8.5 in. (21.6 cm), not to exceed a Max.
cut of 9.5 in. (24.1 cm) in diameter depending on type of
wood. Practice cutting a few small limbs using the following
technique to get the "feel" of using the saw before you begin a
major sawing operation.
• Take the proper stance in front of the tree with the
saw OFF (Fig. 22).
• Squeeze the On/Off switch and let the chain accelerate to
full speed before entering the cut.
• Keep the saw running the entire time you are cutting;
maintain a steady speed.
• Allow the chain to cut for you; exert only light downward
pressure. If you force the cut, damage to the bar, chain, or
unit can result.
• PUSH and PULL – This reaction force is always opposite
to the direction the chain is moving when it is in contact
with the wood. Thus, the operator must be ready to
control the PULL when cutting on the bottom edge of the
bar, and PUSH when cutting along the top edge.
• Do not put pressure on the saw at the end of the cut.
Pruning
Pruning is the process of trimming limbs from a live tree.
• Remove long branches in several stages.
• Cut lower branches first to allow the top branches more
room to fall.
• When pruning trees, it is important not to make the
finishing cut next to the main limb or trunk until you have
