POLE SAW OPERATING PROCEDURES
• Keep bystanders, especially children and pets, at least
50 ft (15 m) away.
• Wear safety glasses or goggles that are marked as
meeting ANSI Z87.1 standards, and ear/hearing
protection when operating this unit. Wear a face or
dust mask if the operation is dusty. Wear a hard hat.
• Wear heavy, long pants, boots, gloves and a long sleeve
shirt. Do not wear loose clothing, jewelry, short pants,
sandals or go barefoot. Secure hair above shoulder level.
• Use the unit only in daylight or good artificial light.
•
Use the right tool. Only use this tool for the purpose
intended.
• Always stop the engine/motor when operation is
delayed or when walking fr
om one location to another.
• Use only genuine factory replacement parts and
accessories for this unit. These are available from
your authorized service dealer. Use of any unauthorized
parts or accessories could lead to serious injury to the
user or damage to the unit, and void your warranty.
KICKBACK SAFETY PRECAUTIONS
• With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
• Grip saw firmly. Hold the pole saw firmly with both
hands when the motor is running. Keep a good firm grip
on the saw with both hands, the right hand on the r
ear
handle, and the left hand on the front handle.
• Do not let the nose of the guide bar contact a log,
branch, gr
ound or other obstr
uction.
•
Always cut with the engine r
unning at full speed. Fully
squeeze the throttle trigger and maintain a steady
cutting speed.
RULES FOR SAFE OPERATION
• Do not over reach.
• Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
• Use only replacement bars and chains specified by the
manufacturer or the equivalent.
OTHER SAFETY PRECAUTIONS
• DO NOT operate a pole saw with one hand! Serious
injury to the operator, helpers, or bystanders may
result from one-handed operation. A pole saw is
intended for two-handed use.
• Do not operate a pole saw if you are fatigued.
• Do not wear loose clothing or jewelry, as they can get
caught in moving parts. Non-skid footwear is
recommended when working outdoors. Wear
protective hair covering to contain long hair.
• Use safety glasses, safety footwear, snug fitting
clothing, protective gloves, and protective hearing and
head gear.
• Use caution when handling fuel. Move the pole saw at
lest 10 feet (3 m) from the fueling point before starting
the engine.
• Do not allow other persons to be near the pole saw
when starting or cutting with the pole saw. Keep
bystanders and animals out of the work area.
• Keep the work area clean. Cluttered areas invite
injuries. Do not start cutting until you have a clear
work area, secure footing, and a planned retreat path
from the falling branches.
• Stay Alert. Watch what you are doing. Use common
sense. Do not operate the pole saw when you are
tired. Keep all parts of your body away from the saw
chain when the motor is operating. Before you start
the saw, make sure the saw chain is not contacting
anything.
• Disconnect the pole saw when not in use, before
servicing, and when changing accessories and
attachments such as saw chain and guard.
•
Check damaged par
ts. Befor
e fur
ther use of the pole
saw, a guard or other part that is damaged should be
carefully checked to determine that it will operate
pr
operly and per
for
m its intended function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions
that may af
fect its operation. A guar
d or other par
t that
is damaged should be properly repaired or replaced by
an authorized service center, unless otherwise
indicated in this instr
uction manual.
Kickback may occur
when the nose or tip
of the guide bar touches an object, or when
the wood closes in and pinches the saw
chain in the cut. Tip contact in some cases
may cause a lightning-fast reverse action,
kicking the guide bar rapidly back towards
the operator. Pinching the saw chain along
the top of the guide bar may push the guide
bar rapidly back towards the operator.
Either of these reactions may cause you to
lose control of the saw, which could result in
serious injury to the user.
Do not rely exclusively upon the safety
devices built into your saw. As a pole saw
user, you should take several steps to keep
your cutting jobs fr
ee fr
om accident or injury.
WARNING:
5
• Use extreme caution when cutting small sized brush
and sapling, as slender material may catch the saw
chain and be whipped towar
d you or pull you off
balance. Do not operate a pole saw in a tree unless
you are specifically trained to do so. When cutting a
limb that is under tension, be alert for spring back so
that you will not be struck when the tension in the
wood fibers is r
eleased. Do not expose the pole saw
to rain. Do not use the pole saw in damp or wet
locations. Do not use the pole saw in the presence of
flammable liquids or gases.
• All pole saw service, other than the items listed in the
user manual safety and maintenance instructions,
should be performed by competent pole saw
personnel. Do not attempt to repair it yourself; there
are no user serviceable parts inside.
•
When not in use, pole saws should be stored out of
the r
each of children, in a dry, high or locked-up place.
When storing saw, use a scabbard or carrying case.
• The pole saw will do a better and safer job when used
at the rate for which it was intended.
• Use the right tool. Cut wood only. Do not use the pole
saw for purposes for which it was not intended. For
example, do not use the pole saw for cutting plastic,
masonry, or non-building materials.
• Use devices, such as low-kickback chain, guide bar
nose guards and special guide bars, which reduce the
risks associated with kickback.
• There are no other replacement components for
achieving kickback protection in accordance with CSA
Z62.3.
• Do not operate a pole saw that is damaged,
improperly adjusted, or not completely and securely
assembled. Be sure that the saw chain stops moving
when the trigger is released.
•
Do not attempt operations beyond your capacity or
experience.
• Never remove, modify or make inoperative any safety
device furnished with your unit.
•

Fig. 13
SAW CHAIN TENSION ADJUSTMENT
Pr
oper tension of the saw chain is extremely important
and must be checked before starting, as well as during,
any cutting operation. Taking the time to make needed
adjustments to the saw chain will result in improved
cutting performance and prolonged chain life.
NOTE: A new chain and bar will need r
eadjustment after
as few as 5 cuts. This is normal during the
break-in period, and the interval between future
adjustments will lengthen quickly (Fig. 13).
If a chain is too loose
or too tight, the bar,
chain and saw bearings will wear more
rapidly. Refer to Figure 14 for information
concerning correct cold tension (A), correct
war
m tension (B), and a chain in need of
adjustment (C).
CAUTION:
A
C
B
To adjust the saw chain tension:
1. Loosen the bar retaining nuts so they are hand tight
(Fig. 8a).
2. Holding the nose of the bar up, use the screwdriver or
scr
ench (if pr
ovided in your unit’
s har
dwar
e pack) to
turn the guide bar adjustment screw clockwise to
tighten the chain (Fig. 8b). Turning the screw
counterclockwise loosens the chain on the guide bar.
3.
While wearing heavy duty work gloves (after you’ve
made the adjustment), move the saw chain back and
forth on the guide bar to be sure the chain moves
fr
eely and is in pr
oper mesh with the sprocket. Never
move the chain with your bare hands.
NOTE: IF the chain is difficult to rotate or if it binds on
the guide bar
, ther
e is too much tension applied
and it must be adjusted. T
o decr
ease tension,
turn the adjustment screw counterclockwise,
slowly
. Move the chain back and for
th until it
moves fr
eely
.
4.
Holding the nose in upper position, secur
ely tighten
the bar retaining nuts.
12
OILING THE CHAIN
The pole saw chain is self-lubricating. Oil is dispersed
onto the chain as the unit is used. Keep an adequate
amount of oil in the oil tank. Use the bar-chain oil
provided in the hardware pack. Always use bar-chain
and sprocket oil or similar chain saw oil.
GUIDE BAR MAINTENANCE
NOTE: Proper maintenance of the guide bar is essential
to the performance of your pole saw. Proper
guide bar maintenance will keep your saw in
good working order.
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge
settings cause most guide bar problems, primarily
resulting in uneven bar wear. As the bar wears unevenly,
the rails widen, which may cause chain clatter and
difficulty in making straight cuts.
Insufficient guide bar lubrication and operating the saw
with a chain that is
too tight will contribute to rapid bar
wear. Refer to Saw Chain Tension Adjustment.
To help minimize bar wear, the following guide bar
maintenance is recommended:
Bar Wear
Turn guide bar frequently at regular intervals (for
example, after 5 hours of use), to ensure even wear on
top and bottom of bar.
Ensur
e that the unit
is off and the spark
plug is disconnected (gas powerheads) before
performing any maintenance on your saw.
WARNING:
Bar Grooves
Bar grooves (or rails which support and carry the chain)
should be cleaned if the saw has been heavily used or if
the saw chain appears dirty. Rails should always be
cleaned every time the saw chain is removed.
T
o clean guide bar rails:
1. Remove sprocket cover, bar and chain. Refer to Saw
Chain Replacement / Installation
.
2. Using a screwdriver, putty knife, wire brush or other
similar instrument, clear residue from the rails on the
guide bar (Fig. 14).
This will keep the oil passages open to provide
proper lubrication to the bar and chain.
3. Reinstall the bar, chain and bar bolt retaining nuts.
Refer to
Saw Chain Replacement / Installation.
MAINTENANCE AND REPAIR INSTRUCTIONS
Fig. 14
Oil Passages
Oil passages at bar pad should be cleaned to insure
proper lubrication of the bar and chain during operation.
This can be done using a soft wire small enough to insert
into the oil discharge hole.

MAINTENANCE AND REPAIR INSTRUCTIONS
CHAIN MAINTENANCE
A low-kickback saw chain should always be used in
conjunction with other kickback protection devices such
as the hand guard, which is furnished with your unit.
Always use a r
eplacement saw chain designed as “low-
kickback” or a saw chain which meets the low-kickback
per
formance.
A standard saw chain (a chain which does not have the
kickback reducing guard links) should only be used by
an experienced professional chain saw operator.
Low-Kickback Saw Chain
A low-kickback saw chain is a chain which has met the
kickback performance requirements of ANSI B175.1. Do
not use other replacement chain unless it has met these
requirements for your specific model.
By keeping the saw chain in good working condition and
correctly serviced as recommended in this manual, you
will be able to maintain the safety system of your chain
saw over the life of the product.
Ensure that the unit
is off and the spark
plug is disconnected (for gas powerheads)
when working on the saw chain. Wear heavy
duty gloves too.
WARNING:
Never remove,
modify or make
inoperative any safety device furnished with
your unit. The low kick back saw chain is a
major safety feature provided for your
protection.
WARNING:
Unless you have
experience and
specialized training for dealing with
kickback (see Important Safety Instructions),
always use a low-kickback saw chain,
which significantly reduces the danger of
kickback. Low-kickback saw chain does not
completely eliminate kickback. A low-
kickback or “safety chain,” should never be
regarded as total protection against injury.
WARNING:
Chain Tension
Check the chain tension frequently and adjust as often
as necessary to keep the chain snug on the bar, but
loose enough to be pulled around by hand. Refer to
Saw
Chain Tension Adjustment.
Br
eaking in a New Saw Chain
A new chain and bar will need readjustment after as few
as 5 cuts. This is normal during the break-in period, and
the interval between future adjustments will begin to
lengthen quickly.
Over a period of time, however, the moving parts of the
saw chain will become worn, resulting in what is called
chain stretch. This is normal. When it is no longer
possible to obtain correct chain tension adjustment, a
link will have to be removed to shorten the chain. See
your TrimmerPlus Authorized Service Center to have this
repair performed.
Never use a loop of
chain that has more
than 3 links removed from it. This could
damage the sprocket.
