Warning – McCulloch MAC 838 User Manual

Page 4

Make sure the chain will not make contact

with any object while starting the engine.

Never try to start the saw when the guide

bar is in a cut.

Do not put pressure on the saw at the end of

the cut. Applying pressure can cause you to

lose control of the chain saw when the cut is

completed and may cause serious personal

injury.

Stop the engine before setting the saw down.

Do not operate a chain saw that is dam-

aged, improperly adjusted, or not com-

pletely and securely assembled. Always

replace bar, chain, hand guard, or chain

brake immediately if it becomes damaged,

broken or is otherwise removed.

With the engine stopped, hand carry the

chain saw with the muffler away from your

body, and the guide bar and chain to the

rear, preferably covered with a scabbard.

CHAIN SAW SAFETY EQUIPMENT

NOTE:

In this section, the safety features of

the chain saw and their function are explained.

For inspection and maintenance, see instruc-

tions in the CHECKING, MAINTAINING AND

SERVICING CHAIN SAW SAFETY EQUIP-

MENT section. See instructions under the

WHAT IS WHAT? section, to find where these

parts are located on your chain saw. The life

span of the machine can be reduced and the

risk of accidents can increase if machine

maintenance is not carried out correctly and

if service and/or repairs are not carried out

professionally. If you need further informa-

tion, please contact your nearest service

dealer.
S

Chain brake. Your chain saw is equipped

with a chain brake that is designed to stop

the chain from moving.

WARNING

: The chain brake is de-

signed to stop the chain immediately if you

get a kickback. The chain brake reduces the

risk of accidents, but only you can prevent

them. DO NOT ASSUME THAT THE CHAIN

BRAKE WILL PROTECT YOU IN THE

EVENT OF A KICKBACK.
S

Throttle trigger lock--out. The throttle

lock--out is designed to prevent accidental

operation of the throttle trigger.

Chain catcher. The chain catcher is de-

signed to catch the saw chain if it breaks.

Vibration damping system. Your chain

saw is equipped with a vibration damping

system that is designed to minimize vibra-

tion and make operation easier.

SAFETY NOTICE:

Exposure to vibrations

through prolonged use of gasoline powered

hand tools could cause blood vessel or nerve

damage in the fingers, hands, and joints of peo-

ple prone to circulation disorders or abnormal

swellings. Prolonged use in cold weather has

been linked to blood vessel damage in other-

wise healthy people. If symptoms occur such

as numbness, pain, loss of strength, change in

skin color or texture, or loss of feeling in the fin-

gers, hands, or joints, discontinue the use of

this tool and seek medical attention. An anti-

vibration system does not guarantee the avoid-

ance of these problems. Users who operate

power tools on a continual and regular basis

must monitor closely their physical condition

and the condition of this tool.
S

ON/STOP switch. The ON/STOP switch

should be used to stop the engine.

CHECKING, MAINTAINING AND

SERVICING CHAIN SAW SAFETY

EQUIPMENT

WARNING

: Never use a chain saw

with defective safety equipment. Safety

equipment must be inspected and main-

tained. If your chain saw does not pass in-

spection, take the saw to your nearest ser-

vice dealer for repair.
S

Chain brake. Brush off any wood dust,

resin and dirt from the chain brake and

clutch drum. Dirt and wear can impair op-

eration of the brake. For additional infor-

mation, see OPERATING YOUR UNIT

section.

Throttle trigger lock--out. Check that the

throttle trigger can not be operated until the

throttle lock--out is pressed.

Chain catcher. Check that the chain

catcher is not damaged and is firmly at-

tached to the body of the chain saw.

Vibration damping system. Regularly

check the vibration damping units for

cracks or deformation. Make sure the

vibration damping units are securely at-

tached to the engine unit and handle unit.

ON/STOP switch. Start the engine and

make sure the engine stops when you

move the ON/STOP switch to the STOP

position.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

Have all chain saw service performed by a

qualified service dealer with the exception of

the items listed in the maintenance section of

this manual. For example, if improper tools

are used to remove or hold the flywheel

when servicing the clutch, structural damage

to the flywheel can occur and cause the fly-

wheel to burst.

Make certain the saw chain stops moving

when the throttle trigger is released. For

correction, refer to CARBURETOR AD-

JUSTMENTS.

Never modify your saw in any way. Use

only attachments supplied or specifically

recommended by the manufacturer.

Keep the handles dry, clean, and free of oil

or fuel mixture.

Keep fuel and oil caps, screws, and fas-

teners securely tightened.

Use only McCullochR accessories and re-

placement parts as recommended.

HANDLE FUEL WITH CAUTION

Do not smoke while handling fuel or while

operating the saw.

Eliminate all sources of sparks or flame in

the areas where fuel is mixed or poured.

There should be no smoking, open flames,

or work that could cause sparks. Allow en-

gine to cool before refueling.
