INTRODUCTION

INTRODUCTION / INTRODUCCIÓN

Page 3 — English

WARNING:

Read and understand all instructions. Failure

to follow all instructions listed below, may result

in electric shock, fire and/or serious personal

injury.

READ ALL INSTRUCTIONS

Know your tool. Read the operator’s manual

carefully. Learn the saw’s applications and lim-

itations as well as the specific potential hazards

related to this tool.

 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 reaction, kicking the guide

bar up and back toward the operator. Pinching

the saw chain along the top of the guide bar

may push the guide bar rapidly back toward the

operator. Either of these reactions may cause

you to lose control of the saw, which could result

in serious personal injury. Do not rely exclusively

upon the safety devices built into the saw. As a

chain saw user, you should take several steps

to keep your cutting jobs free from accident or

injury.

• With a basic understanding of kickback,

you can reduce or eliminate the element

of surprise. Sudden surprise contributes to

accidents.

• Keep a good firm grip on the saw with both

hands when the engine is running. Place your

right hand on the rear handle and your left

hand on the front handle with your thumbs

and fingers encircling the chain saw handles.

A firm grip together with a stiff left arm will

help you maintain control of the saw if kick-

back occurs.

• Make sure that the area in which you are

cutting is free from obstructions. DO NOT

let the nose of the guide bar contact a log,

branch, fence, or any other obstruction that

could be hit while you are operating the saw.

• Cut at high engine speeds. Always cut

with the engine running at full speed. Fully

squeeze the throttle trigger and maintain a

steady cutting speed.

• Do not overreach or cut above chest height.

• Follow the manufacturer’s sharpening and

maintenance instructions for the saw chain.

• Only use replacement bars and chains spec-

ified by the manufacturer or the equivalent.

Do not operate a chain saw with one hand.

Serious injury to the operator, helpers, bystand-

ers, or any combination of these persons may

result from one-handed operation. A chain saw

is intended for two-handed use.

Do not operate a chain saw when you are

fatigued. Fatigue causes carelessness. Never

operate a chain saw when you are tired or under

the influence of medication, drugs, or alcohol.

Use safety footwear. Wear snug-fitting cloth-

ing, protective gloves, and eye, hearing, and

head protection devices.

 Heavy protective clothing may increase oper-

ator fatigue, which could lead to heat stroke.

During weather that is hot and humid, heavy

work should be scheduled for early morning

or late afternoon hours when temperatures are

cooler.

Do not stand on any unstable surface while

using the chain saw, such as ladders, scaffolds,

trees, etc.

Use caution when handling fuel. Move the

chain saw at least 30 feet from the fueling point

before starting the engine.

Do not allow other persons to be near the

chain saw when starting or cutting with the

chain saw. Keep bystanders and animals out

of the work area.

Do not start cutting until you have a clear

work area, secure footing, and a planned retreat

path from the falling tree.

Keep all parts of your body away from the

saw chain when the engine is running.

Always carry the chain saw with the engine

stopped and the brake engaged, the guide bar

and saw chain to the rear, and the muffler away

from your body. When transporting the chain

saw, use the appropriate guide bar scabbard.

GENERAL SAFETY RULES

Page 4 — English

WARNING:

The warnings, labels, and instructions found

in this section of the operator’s manual are for

your safety. Failure to follow all instructions may

result in serious personal injury.

Do not cut vines and/or small underbrush (a

diameter of less than 3 in.).

Muffler surfaces are very hot during and after

operation of the chain saw; keep all body parts

away from the muffler. Serious burns may occur

if contact is made with the muffler.

Always hold the chain saw with both hands

when the engine is running. Use a firm grip

with thumbs and fingers encircling the chain

saw handles.

Never let anyone use the chain saw who

has not received adequate instructions in its

proper use. This applies to rentals as well as

privately owned saws.

Before you start the engine, make sure the

saw chain is not contacting any object.

Do not operate a chain saw that is damaged,

improperly adjusted, or not completely and

securely assembled. Be sure that the saw chain

stops moving when the throttle control trigger

is released.

Shut off the engine before setting the chain

saw down. Do not leave the engine running

unattended. As an additional safety precaution,

apply the chain brake prior to setting down the

saw.

Use extreme caution when cutting small-size

brush and saplings because slender material

may catch the saw chain and be whipped

toward you or pull you off balance.

When cutting a limb that is under tension,

be alert for springback so that you will not be

struck when the tension in the wood fibers is

released.

Keep the handles dry, clean, and free of oil or

fuel mixture.

Do not start or operate the engine in a con-

fined space, building, near open windows,

or in other unventilated space where dan-

gerous carbon monoxide fumes can collect.

Carbon monoxide, a colorless, odorless,

and extremely dangerous gas, can cause

unconsciousness or death.

Do not operate a chain saw in a tree unless

you have been specifically trained to do so.

Do not cut from a ladder; this is extremely

dangerous.

All chain saw service, other than the items

listed in the instruction manual and all main-

tenance, should be performed by competent

chain saw service personnel. (For example, if

improper tools are used to remove the flywheel

or if an improper tool is used to hold the flywheel

in order to remove the clutch, structural damage

to the flywheel could occur and subsequently

could cause the flywheel to burst.)

Always have a fire extinguisher available

when using chain saw.

Use only the replacement guide bars and low

kickback chains specified for the saw.

Do not adapt the powerhead to a bow guide

or use it to power any attachments or devices

not listed for the saw.

The gas powered saw (or electrically pow-

ered saw) is classified by CSA as a Class 1C

(or Class 2C) saw. It is intended for infrequent

use by homeowners, cottagers, and campers,

and for such general applications as clearing,

pruning, cutting firewood, etc. It is not intended

for prolonged use. Prolonged periods of opera-

tion can cause circulatory problems in the user’s

hands due to vibration.

Save these instructions. Refer to them

frequently and use to instruct other users. If

you loan someone this tool, loan them these

instructions also.

GENERAL SAFETY RULES

SPECIFIC SAFETY RULES

Page 5 — English

SPECIFIC SAFETY RULES

Wear snug-fitting clothing. Always wear heavy

long pants, boots, and gloves. Do not wear

jewelry, short pants, sandals, or go barefoot.

Do not wear loose fitting clothing, which could

be drawn into the engine or catch the chain

or underbrush. Wear overalls, jeans, or chaps

made of cut-resistant material or ones that

contain cut-resistant inserts. Secure hair so that

it is above shoulder level.

Wear non-slip safety footwear and heavy-

duty gloves to improve your grip and to protect

your hands.

Wear eye protection with side shields marked

to comply with ANSI Z87.1, along with hear-

ing and head protection, when operating this

equipment.

Keep bystanders and animals out of the work

area. Do not allow other persons to be nearby

during starting or cutting with the chain saw.

NOTE: The size of the work area depends on the

job being performed as well as the size tree or

workpiece involved. For example, felling a tree

requires a larger work area than making other

cuts (i.e., bucking cuts, etc.).

Keep SAFE-T-TIP™ anti-kickback nose guard

properly mounted on the guide bar to prevent

rotational kickback.

Follow the sharpening and maintenance

instructions for the saw chain.

Never operate a chain saw that is damaged,

improperly adjusted, or is not completely

and securely assembled. Be sure that the saw

chain stops moving when the throttle control

trigger is released. If the saw chain moves at

idle speed, the carburetor may need adjusting.

Refer to Adjusting the Carburetor in the Main-

tenance section of this manual. If the saw chain

still moves at idle speed after adjustment has

been made, contact a qualified service center

for adjustment and discontinue use until the

repair is made.

This product is intended for infrequent use

by homeowners and other occasional users

for general applications such as clearing, prun-

ing, cutting firewood, etc. It is not intended for

prolonged use. Prolonged periods of operation

can cause circulatory problems in the user’s

hands due to vibration. For such use, it may be

appropriate to use a product having an anti-

vibration feature.

REFUELING (DO NOT SMOKE!)

To reduce the risk of fire and burn injury,

handle fuel with care. It is highly flammable.

Mix and store fuel in a container approved for

gasoline.

Mix fuel outdoors where there are no sparks

or flames.

Select bare ground, stop the engine, and

allow it to cool before refueling.

Loosen the fuel cap slowly to release pressure

and to keep fuel from escaping around the cap.

Tighten the fuel cap securely after refueling.

Wipe spilled fuel from the unit. Move 30 feet

away from refueling site before starting engine.

Never attempt to burn off spilled fuel under

any circumstances.

KICKBACK

Kickback is a dangerous reaction that can

lead to serious injury. Do not rely only on the

safety devices provided with the saw. As a

chain saw user, you must take special safety

precautions to help keep your cutting jobs free

from accident or injury. See the General Safety

Rules and Operation sections of this manual

for added information on kickback and how to

avoid serious personal injury.

CAUTION: User not to use a replacement saw

chain unless it has been designated as meet-

ing the kickback performance requirements in

ANSI/OPEI B175.1-2012 on that specific power

head, or has been designated as low-kickback

outdoors. If the engine is hot, allow to cool for

at least five minutes before adding fuel. Imme-

diately replace fuel cap after fueling and tighten

securely. Move at least 30 ft. from refueling site

before starting the engine. Do not smoke and

stay away from open flames and sparks. Fail-

ure to heed this warning can result in possible

personal injury.

BAR AND CHAIN LUBRICATION

See Figure 3.

The bar and chain require continuous lubrication.

Lubrication is provided by the automatic oiler

system when the oil tank is kept filled. Lack of

lubricant will quickly ruin the bar and chain. Too

little lubricant will cause overheating shown by

smoke coming from the chain and/or discolor-

ation of the bar. Lubrication can be increased or

decreased by turning (up to 1/4 turn maximum)

the adjustment screw located on the bottom of

the crankcase with the screwdriver end of the

included combination wrench.

WARNING:

NEVER adjust the automatic oiler system when

the engine is running. Failure to do so could

cause serious personal injury.

OPERATION

ADDING BAR AND CHAIN LUBRICANT

See Figure 3.

Use a bar and chain lubricant designed for lubri-

cating chain saw chains. They are formulated to

extend bar and chain life by protecting against

wear and reducing friction and heat. Chain saw

should use approximately one tank of lubricant

per tank of fuel.

oil pump, bar, or chain.

Carefully pour the bar and chain lubricant into

the oil tank.

Fill the oil tank every time you fuel the engine.

OPERATING THE CHAIN BRAKE

See Figures 4 - 5.

Check the operating condition of the chain brake

prior to each use.

Using the back of your left hand, engage the

chain brake by pushing the chain brake lever/

hand guard toward the bar while the chain is

rotating rapidly.

Reset the chain brake back into the RUN posi-

tion by grasping the top of the chain brake lever/

hand guard and pulling toward the front handle

until you hear a click.

WARNING:

If the chain brake does not stop the chain imme-

diately, or if the chain brake will not stay in the

run position without assistance, take the saw to

a qualified service center for repair prior to use.

STARTING THE ENGINE

See Figures 6 - 10.

The starting method differs depending on whether

the engine is cold or warm.

WARNING:

Keep your body to the left of the chain line.

Never straddle the saw or chain, or lean over

past the chain line.

Place the chain saw on level ground and ensure

that no objects or obstructions are in the imme-

diate vicinity that could come in contact with the

bar and chain. To prevent rapid dulling of the

chain, do not allow the bar and chain to contact

dirt on the ground.

 Hold the front handle firmly with your left hand

and put your right foot onto the base of the rear

handle.

STOP

STOPPING THE ENGINE

See Figures 11 - 12.

Release the throttle trigger and let the engine

return to idle. To stop the engine, move the on/

stop switch to the STOP ( ) position. Do not put

the chain saw on the ground when the chain is still

moving. For additional safety, set the chain brake

when the saw is not in use.

In the event that the on/stop switch will not stop the

saw, pull the choke knob out to the fully extended

position (FULL CHOKE / ) and engage chain

brake to stop the engine. If the on/stop switch will

not stop the saw when set to the STOP position,

have the on/stop switch repaired before using the

chain saw again to prevent unsafe conditions or

serious injury.

NOTE: When you are finished using the saw,

always relieve tank pressure by loosening, then

retightening, the chain oil and fuel mix caps. Allow

the engine to cool before storing.

ADJUSTING IDLE SPEED

See Figure 13.

WARNING:

The chain will move around the guide bar when

adjusting the idle speed. Wear all protective

clothing and keep all bystanders, children, and

pets at least 50 ft. away. Make adjustments

with the unit supported on a stable surface so

that the chain/guide bar does not contact the

ground or any object. Keep all parts of your

body away from the chain/guide bar and muf-

fler. Failure to follow these instructions could

result in serious personal injury.

If the engine starts, runs, and accelerates,

but will not idle, turn the idle speed screw “T”

clockwise to increase idle speed.

If the chain turns at idle, turn the idle speed

screw “T” counterclockwise to reduce the

idle RPM and stop the chain movement. If the

saw chain still moves at idle speed, contact

a qualified service center for adjustment and

discontinue use until the repair is made.

WARNING:

THE SAW CHAIN SHOULD NEVER TURN AT

clockwise to reduce the idle RPM and stop the

chain, or contact a qualified service center for

adjustment and discontinue use until the repair

is made. Serious personal injury may result from

the saw chain turning at idle.

PULL AND PUSH

See Figure 14.

The reaction force of the saw is always opposite to

the direction the chain is moving. Thus, the operator

must be ready to control the PULL when cutting

on the bottom edge of the bar and the PUSH when

cutting along the top edge.

NOTE: The chain saw has been fully factory tested.

It is normal to find some slight lubricant residue

on the saw.

WARNING:

KICKBACK occurs 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 saw chain in the cut. 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 saw chain is pinched along the top of the

guide bar, the guide bar can be driven rapidly

back toward the operator. Either of these reac-

tions can cause loss of saw control, which can

result in serious injury.

Do not rely exclusively upon the safety devices

built into the saw. As a chain saw user, you

should take steps to keep your cutting jobs

free from accident or injury. See General Safety

Rules for more details.

KICKBACK PRECAUTIONS

See Figures 15 - 16.

Rotational kickback occurs when the moving chain

contacts an object at the Kickback Danger Zone of

the guide bar. The result is a lightning-fast reverse

reaction, which kicks the guide bar up and back

towards the operator. This reaction can cause loss

of control, which can result in serious injury.

PREPARING FOR CUTTING

PROPER GRIP ON HANDLES

See Figure 17.

See General Safety Rules for appropriate safety

equipment.

Wear non-slip gloves for maximum grip and

protection.

Hold the saw firmly with both hands. Always

keep your left hand on the front handle and your

right hand on the rear handle so that your body

is to the left of the chain line.

WARNING:

Never use a left-handed (cross-handed) grip or

any stance that would place your body or arm

across the chain line.

Maintain a proper grip on the saw whenever the

engine is running. The fingers should encircle

the handle and the thumb is wrapped under the

handlebar. This grip is least likely to be broken

by a kickback or other sudden reaction of the

saw. Any grip in which the thumb and fingers

are on the same side of the handle is dangerous

because a slight kick of the saw can cause loss

of control.

PROPER CUTTING STANCE

See Figure 18.

WARNING:

Always use the proper cutting stance described

in this section. Never kneel when using the

chain saw, except when felling a tree as illus-

trated in Figure 23. Kneeling could result in

loss of stability and control of the chain saw,

resulting in serious personal injury.

Keep left arm with elbow locked in a “straight

arm” position to withstand any kickback force.

Keep your body to the left of the chain line.

Keep your thumb on underside of handlebar.

WORK AREA PRECAUTIONS

See Figure 19.

Cut only wood or materials made from wood;

no sheet metal, no plastics, no masonry, no

non-wood building materials.

Never allow children to operate the saw. Allow

no person to use this chain saw who has not

read this operator’s manual or received ade-

quate instructions for the safe and proper use

of this chain saw.

Keep everyone – helpers, bystanders, children,

and animals, a SAFE DISTANCE from the

cutting area. During felling operations, the safe

distance should be a least twice the height of the

largest trees in the felling area. During bucking

operations, keep a minimum distance of 15 feet

between workers.

Always cut with both feet on solid ground to

prevent being pulled off balance.

Do not cut above chest height as a saw held

higher is difficult to control against kickback

forces.

Do not fell trees near electrical wires or build-

ings. Leave this operation for professionals.

Cut only when visibility and light are adequate

for you to see clearly.

OPERATION

WARNING:

DO NOT operate the throttle trigger with your

left hand and hold the front handle with your

right hand. Never allow any part of your body

to be in the chain line while operating a saw.

CHAIN LINE

BASIC OPERATING/CUTTING

PROCEDURES

Practice cutting a few small logs 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 wood with

the saw idling.

Accelerate the engine to full throttle just before

entering the cut by squeezing the throttle trigger.

Begin cutting with the saw against the log.

Keep the engine at full throttle the entire time

you are cutting.

Allow the chain to cut for you; exert only light

downward pressure. Forcing the cut could result

in damage to the bar, chain, or engine.

Release the throttle trigger as soon as the cut is

completed allowing the engine to idle. Running

the saw at full throttle without a cutting load can

result in unnecessary wear to the chain, bar, and

engine.

Do not put pressure on the saw at the end of

the cut.

FELLING TREES

HAZARDOUS CONDITIONS

See Figures 20 - 23.

WARNING:

Do not fell trees during periods of high wind or

heavy precipitation. Wait until the hazardous

weather has ended.
