State and Local Requirements

Your saw is equipped with a temperature limiting muffler and a spark arresting screen in order to comply
with the requirements of SAE Recommended Practice J335 and California Codes 4442 and 4443. All

national forest land and land managed by the states of California, Maine, Washington, Idaho,
Minnesota, New Jersey and Oregon require internal combustion engines to be equipped with a
spark arrester screen by law. Other states and federal agencies are enacting similar regulations.

If you operate a chain saw in a state or locale where such regulations exist, you are legally responsible for
maintaining the operating condition of these parts. Failure to do so is a violation of a law. Spark arrester

maintenance is described in the Maintenance-Spark Arresting Muffler Section of the manual.
Note: When using a chainsaw for logging purposes, refer to Code of Federal Regulations, Parts

1910 and 1928.

WARNING:The ignition system of your unit produces an electromagnetic field of a very low
intensity. This field may interfere with some pacemakers. To reduce the risk of serious or
fatal injury, persons with pacemaker should consult their physician and the pacemaker
manufacturer before operating this tool.

WARNING: 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.

SAFETY RULES

Basic Safety Precautions

• Read this manual carefully until you completely understand and
can follow all safety rules, precautions, and operating instruc­tions before attempting to use the unit.

• Restrict the use of your saw to adult users who understand and
can follow safety rules, precautions, and operating instructions
found in this manual. Minors should never be allowed to use a
chainsaw.

• Do not handle or operate a chain saw when you are fatigued,
ill, or upset, or if you have taken alcohol, drugs, or medication.
You must be in good physical condition and mentally alert.
Chain saw work is strenuous. If you have any condition that
might be aggravated by strenuous work, check with your doctor
before operating a chain saw (Fig. 1). Be more cautious before
rest periods and towards the end of your shift.

• Keep children, bystanders, and animals a minimum of 35 feet
(10 meters) away from the work area. Do not allow other peo­ple or animals to be near the chain saw when starting or ope­rating the chain saw (Fig. 2).

• Major cases of chainsaw accidents happen when the chain hits
the operator. While working with the chainsaw, always use
safety protective approved clothing. The use of protective
clothing does not eliminate injury risks, but reduces the injury
effects in case of accident. Consult your trusted supplier to
choose equipment in compliance with legislation. The clothing
must be proper and not an obstacle. Wear adherent anti-cut
clothing.

Anti-cut jackets (Fig.3), dungarees (Fig.3) and

leggings are ideal.

Do not wear clothes, scarves, ties or
bracelets that may get stuck in wood or twigs. Tie up and pro­tect long hair (example with foulards, cap, helmets, etc.).

Safety
shoes or boots having skid-proof sole and anti-piercing
insert (Fig.4). Wear protective helmet (Fig.5) in places
where there can be falling objects.Wear protective goggles
or face screens! Use protections against noises: for exam­ple noise reduction ear guards (Fig.5) or earplugs.

The use
of protections for the ear requests much more attention and
caution, because the perception of danger audio signals
(screaming, alarms, etc.) is limited.

Wear anti-cut gloves

(Fig.6, page 8).

• Only loan your saw to expert users who are completely familiar
with saw operation and correct use. Give other users the
manual with operating instructions, which they have to read
before using the saw.

• Check the chain saw each day to ensure that each device,
whether for safety or otherwise, is functional.

• Never use a damaged, modified, or improperly repaired or
assembled chain saw. Do not remove, damage or deactivate
any of the safety devices. Only use bars of the length indicated
in the table (page 13). Always replace bar, chain, hand guard,
or chain brake immediately if it becomes damaged, broken or is
otherwise removed.

• Carefully plan your sawing operation in advance. Do not start
cutting until you have a clear work area, secure footing, and, if
you are felling trees, a planned retreat path.

• All saw service, other than the operations shown in the present
manual, have to be performed by competent personnel.

• The chain saw must only be used for cutting wood. It is unadvi­sable to cut other types of material.

• It is unadvisable to hitch tools or applications to the P.t.o. that
are not specified by the manufacturer.

SAFETY RULES

Fuel Handling

WARNING: Gasoline is an extremely flammable fuel.
Use extreme caution when handling gasoline or fuel
mix. Do not smoke or bring any fire or flame near the
fuel or the chainsaw (Fig. 7).

• 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 (Fig. 8).

• Mix fuel outdoors where there are no sparks or flames.

• Select bare ground, stop engine, and allow to cool before
refueling.

• Loosen fuel cap slowly to release pressure and to keep fuel
from escaping around the cap.

• Tighten fuel cap securely after refueling. Unit vibration can
cause an improperly tightened fuel cap to loosen or come off
and spill quantities of fuel.

• Wipe spilled fuel from the unit. Move 10 feet (3 m) away from
refueling site before starting engine (Fig. 9).

• Never attempt to burn off spilled fuel under any circumstances.

• Do not smoke while handling fuel or while operating the saw.

• Store fuel in a cool, dry, well ventilated place.

• Never place the saw in a combustible area such as dry leaves,
straw, paper, etc.

• Store the unit and fuel in an area where fuel vapors cannot
reach sparks or open flames from water heaters, electric
motors or switches, furnaces, etc.

• Never take the cap off the tank when the engine is running.

• Never use fuel for cleaning operations.

• Take care not to get fuel on your clothing.

Operation and Safety

WARNING: 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 (Fig. 10).

• 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 chain
brake engaged, the guide bar and saw chain to the rear, and
the muffler away from your body. When transporting your chain
saw, use the appropriate guide bar scabbard (Fig. 11). When
transporting in a vehicle, keep chain and bar covered with the
chain guard. Properly secure your saw to prevent turnover, fuel
spillage and damage to the saw.

• Apply chain brake prior to any repositioning of the operator in
the cutting area.

•

Do not operate a chain saw with one hand! Serious injury
to the operator, helpers, bystanders, or any combination of
these persons may result from one-handed operation.

A chain

saw is intended for two-handed use.

• Before you start the engine, make sure the saw chain is not
contacting any object. Never try to start the saw when the guide
bar is in a cut.

• Shut off the engine before setting down the saw. Do not leave
the engine running unattended.

SAFETY RULES

• As an additional safety precaution, apply the chain brake prior
to setting down the saw.

• Only use the chain saw in well-ventilated places, do not opera­te the chain saw in explosive or flammable atmospheres or in
closed environments (Fig. 12). Beware of carbon monoxide poi­soning.

• Do not operate saw from a ladder or in a tree. Always cut from
a firm-footed and safe position.

• Do not put pressure on the saw at the end of the cut. Applying
pressure can cause you to lose control when the cut is com­pleted.

• Do not cut near electric cables.

• Keep the handles dry, clean, and free of oil or fuel mixture.

• When the chain saw is running, grip the front handle firmly with
your left hand and the back handle with your right hand (Fig.

10).

• When cutting a limb that is under tension, be alert for spring­back so you will not be struck when the tension in the wood
fibre is released.

• Take great care when cutting small branches or shrubs which
can block the chain, be thrown back towards you or cause you
to lose your balance.

• Never cut with the chain saw above shoulder height (Fig. 13).

• Never start up the chain saw without the chain cover fitted.

Precautions Against Kickback

WARNING: Avoid kickback which can result in
serious injury. Kickback is the backward, upward or
sudden forward motion of the guide bar occurring
when the saw chain near the upper tip of the guide
bar contacts any object such as a log or branch, or
when the wood closes in and pinches the saw chain
in the cut. Contacting a foreign object in the wood
can also result in loss of chain saw control.

• Rotational Kickback can occur when the moving chain con­tacts an object at the upper tip of the guide bar. This contact
can cause the chain to dig into the object, which stops the chain
for an instant. The result is an extremely fast, reverse reaction
which kicks the guide bar up and back toward the operator
(Fig. 14-15 and Fig. 16 page 10).

•

Pinch-Kickback can occur when the wood closes in and
pinches the moving saw chain in the cut along the top of the
guide bar and the saw chain is suddenly stopped. This sudden
stopping of the chain results in a reversal of the chain force
used to cut wood and causes the saw to move in the opposite
direction of the chain rotation. The saw is driven straight back
toward the operator.

•

Pull-In can occur when the moving chain contacts a foreign
object in the wood in the cut along the bottom of the guide bar
and the saw chain is suddenly stopped. This sudden stopping
pulls the saw forward and away from the operator and could
easily cause the operator to lose control of the saw.

Avoid Pinch-Kickback:

• Be extremely aware of situations or obstructions that can cause
material to pinch the top of or otherwise stop the chain.

• Do not cut more than one log at a time.

SAFETY RULES

• Do not twist the saw as the bar is withdrawn from an undercut
when bucking.

Avoid Pull-In:

• Always begin cutting with the engine at full speed and the saw
housing against wood.

• Use wedges made of plastic or wood. Never use metal to hold
the cut open.

Reduce the Risk of Kickback

Recognize that kickback can happen. With a basic
understanding of kickback, you can reduce the
element of surprise which contributes to accidents.

• Never let the moving chain contact any object at the tip of the
guide bar.

• Keep the working area free from obstructions such as other
trees, branches, rocks, fences, stumps, etc. Eliminate or avoid
any obstruction that your saw chain could hit while you are cut­ting through a particular log or branch.

• Keep your saw chain sharp and properly tensioned. A loose or
dull chain can increase the chance of kickback occurring.
Follow manufacturer’s chain sharpening and maintenance
instructions. Check tension at regular intervals with the engine
stopped, never with the engine running. Make sure the chain
brake nuts are securely tightened after tensioning the chain.

• Begin and continue cutting at full speed. If the chain is moving
at a slower speed, there is greater chance of kickback
occurring.

• Cut one log at a time.

• Use extreme caution when re-entering a previous cut.

• Do not attempt cuts starting with the tip of the bar (plunge cuts).

• Watch for shifting logs or other forces that could close a cut and
pinch or fall into chain.

• Use the Reduced-Kickback Guide Bar and Low-Kickback Chain
specified for your saw.

Maintain Control (Fig.17-18)

• Keep a good, firm grip on the saw with both hands when the
engine is running and don’t let go. A firm grip will help you redu­ce kickback and maintain control of the saw. Keep the fingers of
your left hand encircling and your left thumb under the front
handlebar. Keep your right hand completely around the rear
handle whether you are right handed or left handed. Keep your
left arm straight with the elbow locked.

• Position your left hand on the front handlebar so it is in a straight
line with your right hand on the rear handle when making
bucking cuts.Never reverse right and left hand positions for any
type of cutting.

• Stand with your weight evenly balanced on both feet.

• Stand slightly to the left side of the saw to keep your body from
being in a direct line with the cutting chain.

• Do not overreach. You could be drawn or thrown off balance
and lose control of the saw.

SAFETY RULES

• Do not cut above shoulder height. It is difficult to maintain con­trol of saw above shoulder height.

Kickback Safety Features

WARNING: The following features are included on
your saw to help reduce the hazard of kickback;
however, such features will not totally eliminate this
dangerous reaction. As a chain saw user, do not rely
only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this
manual to help avoid kickback and other forces
which can result in serious injury.

• Reduced-Kickback Guide Bar, designed with a small radius tip
which reduces the size of the kickback danger zone on the bar
tip. A Reduced-Kickback Guide Bar has been demonstrated to
significantly reduce the number and seriousness of kick-backs
when tested in accordance with safety requirements for gasoli­ne powered chain saws as set by ANSI B175.1 - 1991.

• Low-Kickback Chain, designed with a contoured depth gauge
and guard link that deflect kickback force and allow wood to
gradually ride into the cutter.Low-Kickback Chain has met kick­back performance requirements when tested on a representa­tive sample of chain saws below 3.8 cubic inch displacement
specified in ANSI B175.1 - 1991.

• Front Hand Guard, designed to reduce the chance of your hand
contacting the chain as your hand slips off the front handlebar.

• Position of front and rear handlebars, designed with distance
between handles and “in-line” with each other.The spread and
“in-line” position of the hands provided by this design work
together to give balance and resistance in controlling the pivot
of the saw back toward the operator if kick-back occurs.

Chain Brake

Chain brakes are designed to rapidly stop the chain from rotating.
When the chain brake lever / hand guard is pushed toward the
bar, the chain should stop immediately.

A chain brake does not

prevent kickback.

The chain brake Run Position (A) and Brake Position (B) are
illustrated on Fig. 19.
Chain brake should be cleaned and tested daily. Clean the chain
brake per the Maintenance-Chain Brake Section and test per the
Operation-Chain Brake Operation Section.

WARNING: Even with proper maintenance, the cor­rect operation at the chain brake under field condi­tions can not be certified.

SAFETY RULES

WARNING: WE DO NOT REPRESENT AND YOU SHOULD NOT ASSUME THAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK. DO NOT RELY UPON ANY OF
THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND
CAREFULLY TO AVOID KICKBACK.

Reduced-Kickback Guide Bar and Low-Kickback Chain

Reduced-kickback guide bars and low-kickback saw chains reduce the chance and magnitude of kickback
and are recommended. Your saw has a low kickback chain and bar as original equipment. Repairs on a
chain brake should be made by an authorized servicing dealer. Take your unit to the place of
purchase if purchased from a servicing dealer, or to the nearest authorized service dealer.

WARNING: Computed kickback angle (CKA) listed on your saw and listed in the CKA table
below represents angle of kickback your bar and chain combinations will have when tested
in accordance with CSA (Canadian Standards Association) and ANSI standards. When
purchasing replacement bar and chain, considerations should be given to the lower CKA
values. Lower CKA values represent safer angles to the user, higher values indicate more
angle and higher kick energies. Computed angles represented indicate total energy and
angle associated without activation of the chain brake during kickback. Activated angle
represents chain stopping time relative to activation angle of chain break and resulting kick
angle of saw. In all cases lower CKA values represent a safer operating environment for the
user.The following guide bar and chain combinations meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1 when used on saws listed in this manual. Use of bar
and chain combinations other than those listed is not recommended and may not meet the
CKA requirements per standard.

WARNING: Do not mount a bow guide on any Efco chainsaw. The risk of kickback is
increased with a bow guide because of the increased kickback contact area.
