the branch will fall.
Branches may fall in unexpected directions. Do not
stand directly under the branch being cut.
The most typical cutting application is to position the
unit at an angle of 60° or less, depending on the specific
situation, as shown in Figure 8 and 9. As the angle of
the pole saw shaft to ground increases, the difficulty of

increases.
Remove long branches in several stages.

more room to fall.
Work slowly, keeping both hands on the saw with a
firm grip. Maintain secure footing and balance.
Keep the tree between you and the chain while
OLPELQJ&XWIURPVLGHRIWUHHRSSRVLWHEUDQFK\RXDUH
cutting.
Do not cut from a ladder; this is extremely dangerous.
Leave this operation for professionals.
Do not make the flush cut next to the main limb
or trunk until you have cut off the limb further out
to reduce the weight. Following proper cutting
procedures will prevent stripping the bark from the
main member.
Do not use the pole saw for felling or bucking.
To prevent electrocution, do not operate within 15m of
overhead electrical lines.
Keep bystanders at least 15m away.
MAINTENANCE
WARNING:
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust
mask.
WARNING:
Before inspecting, cleaning or servicing the unit,
stop the motor, wait for all moving parts to stop,
and disconnect from power supply. Failure to
follow these instructions can result in serious
personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline,
petroleumbased products, penetrating oils, etc.,
FRPHLQFRQWDFWZLWKSODVWLFSDUWV&KHPLFDOVFDQ
damage, weaken, or destroy plastic, which may
result in serious personal injury.
All chain saw service, other than the items listed in the
instruction manual maintenance instructions, should be
performed by competent chain saw service personnel.
CHAIN TENSION
See Figures 10-11
WARNING
To avoid possible serious injury, never touch or
adjust the chain while the motor is running. The
saw chain is very sharp; always wear protective
gloves when performing maintenance to the
chain.
Stop the motor and disconnect from power supply
before setting the chain tension. Make sure the
guide bar nut is loose to finger tight, turn the chain
tensioning screw clockwise to tension the chain.
Refer to
Replacing the Bar and Chain
for additional
information.
NOTE:
A cold chain is correctly tensioned when there
is no slack on the underside of the guide bar, the
chain is snug, but it can be turned by hand without
binding.

the drive links hang out of the bar groove as shown in
Fig. 10.
During normal operation, the temperature of the chain
will increase. The drive links of a correctly tensioned
warm chain will hang approximately .050 in. out of the
bar groove, as shown in fig. 11.
NOTE:
New chain tends to stretch; check chain
tension frequently and tension as required.
