WARNING:

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

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:

• 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. 11

Fig. 13

SAW CHAIN TENSION ADJUSTMENT

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:

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.

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

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

Holding the nose in upper position, secur

ely tighten

the bar retaining nuts.

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.

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.

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.
