POLE SAW NAMES
AND TERMS
Coupling Nut Threaded collar (loosen to
slide inner pole, tighten to hold pole in
position).
Guide Bar Metal bar that extends from saw
body. The guide bar supports and guides
chain.
Inner Pole The moveable section of tubing
to which the saw is attached.
Kickback Quick backward and upward
motion of guide bar. Kickback may occur
when tip of guide bar touches an object
while chain is moving. The guide bar will
kick up and back towards operator.
Oiler Control System for oiling guide bar
and chain.
Outer Pole Retains the moveable inner
pole.
Saw Chain (Chain ) Loop of chain having
cutting teeth for cutting wood. The motor
drives chain. The guide bar supports chain.
Sprocket Toothed wheel that drives chain.
Switch Device that completes or interrupts
electrical circuit to motor of saw.
Switch Lockout Device that reduces acci-
dental starting of saw.
Trigger Device that turns saw on and off.
Squeezing trigger turns saw on.
Releasing trigger turns saw off.
Trimming (Pruning) Process of cutting
limb(s) from a living tree.
Undercut An upward cut from underside of
log or limb. This is done while in normal

on saw backwards. If chain is

and will not cut.
Make sure cutting edges of chain are facing
in the right direction. Position chain so cut-
ting edges on top of guide bar face guide bar
nose (see Figure 2).

SAW CHAIN TENSION
ADJUSTMENT
WARNING: Maintain proper
chain tension. A loose chain will
increase the risk of kick back. A
loose chain may jump out of guide
bar groove. This may injure op-
erator and damage chain. A loose
chain will cause chain, guide bar
and sprocket to wear rapidly.
1. To adjust chain tension, make sure
guide bar nuts are only finger tight.
Also make sure adjusting block is in
oval adjusting hole on guide bar.
2. Turn adjusting screw clockwise until
all slack is out of chain.
Note: There
should be no gap between side links of
chain and bottom of guide bar.
3. Wearing protective gloves, move chain
around guide bar. Chain should move
freely. If chain does not move freely,
loosen chain by turning adjusting screw
counterclockwise.
4. After chain tension is correct, tighten
guide bar nuts firmly. If not, guide bar
will move and loosen chain tension.
This will increase the risk of kickback.
This can also damage saw.
