Do not use the pole chain saw to cut vines and/or small
underbrush.
Prior to each cutting session, run through the daily checklist
(see pg. 18).

WARNING!
Do not cut trees near electrical wires.

WARNING!
Failure to lubricate the chain will cause
damage to the bar and chain. Use only a good quality bar and
chain oil designed specifically for use with chain saws. One
minute of use will consume approximately 0.15 fl oz. (4 ml) of oil.
NOTE: It is normal for oil to seep from the saw when not in
use. To prevent seepage, empty the oil tank after each use.
When storing the unit for a long period of time (3 months or
longer), be sure the chain is lightly lubricated; this will prevent
rust on the chain and bar sprocket.

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. 25). 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 chain 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. 26). 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 with the chain saw head is designed for trimming
small branches and limbs up to recommended 6.5 in.
(16.5 cm), not to exceed a Max. cut of 7.5 in. (19 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. 26).
• 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.
