INSTRUCTIONS

INSTRUCTIONS PERTAINING

TO A RISK OF FIRE,

ELECTRIC SHOCK, OR

INJURY TO PERSONS

WARNING – When using tools, basic pre-

cautions should always be followed,
including the following:

General

To reduce the risks of electric a.

shock, re, and injury to persons,

read all the instructions before us­ing the tool.

Work area

Keep the work area clean and well a.
lighted. Cluttered benches and dark

areas increase the risks of electric

shock, re, and injury to persons.

Do not operate the tool in explo-b.
sive atmospheres, such as in the

presence of ammable liquids,

gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.

Keep bystanders, children, and c.
visitors away while operating the

tool. Distractions are able to result in
the loss of control of the tool.

conditions. Wear heavy-duty work
gloves during use.

Personal safety

Stay alert. Watch what you are do-a.
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inu­ence of drugs, alcohol, or medica­tion. A moment of inattention while

operating the tool increases the risk

of injury to persons.

Dress properly. Do not wear loose b.
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.

Loose clothes, jewelry, or long hair
increases the risk of injury to persons

as a result of being caught in moving
parts.

Avoid unintentional starting. Be c.
sure the switch is off before con­necting to the air supply. Do not

carry the tool with your nger on the

switch or connect the tool to the air
supply with the switch on.

Remove adjusting keys and d.
wrenches before turning the tool
on. A wrench or a key that is left at-

tached to a rotating part of the tool

increases the risk of personal injury.

Do not overreach. Keep proper e.
footing and balance at all times.

Proper footing and balance enables
better control of the tool in unexpect­ed situations.

f. Use safety equipment. A

dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable

g. Always wear eye protec-

tion. Wear ANSI-ap­proved safety goggles.

h. Always wear hearing

protection when using
the tool. Prolonged expo-

sure to high intensity noise

is able to cause hearing loss.

Risk of Electric Shock. This tool i.
is not provided with an insulated
gripping surface. Contact with a

″live″ wire will also make exposed
metal parts of the tool ″live″ and

shock the operator.

Avoid body contact with grounded j.
surfaces such as pipes, radiators,
ranges and refrigerators. There is

an increased risk of electric shock if
your body is grounded.

Explore the workpiece to avoid k.
contact with hidden wiring. Thor-

oughly investigate the workpiece for
possible hidden wiring before per­forming work. Contact with live wiring
will shock the operator.

DANGER! Keep hands and body l.
away from cutting area and blade.
Keep your second hand on aux­iliary handle or motor housing.

Contact with the blade will result in a

serious injury.

Do not reach underneath the work-m.
piece. There is no guard to protect

you from the blade below the work­piece.

Never hold a piece being cut in n.
your hands or across your leg. It is

important to support the work proper-

ly to minimize body exposure, blade
binding, or loss of control.

Tool use and care

Use clamps or another practical a.
way to secure and support the
workpiece to a stable platform.

Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.

Do not force the tool. b. Use the
correct tool for the application. The

correct tool will do the job better and

safer at the rate for which the tool is
designed.

Do not use the tool if the switch c.
does not turn the tool on or off.

Any tool that cannot be controlled
with the switch is dangerous and
must be repaired.

Disconnect the tool from the air d.
source before making any adjust­ments, changing accessories, or
storing the tool. Such preventive

safety measures reduce the risk of
starting the tool unintentionally. Turn
off and detach the air supply, safely
discharge any residual air pressure,
and release the throttle and/or turn
the switch to its off position before
leaving the work area.

Store the tool when it is idle out of e.
reach of children and other un­trained persons. A tool is dangerous

in the hands of untrained users.

Maintain the tool with care. f. Keep a
cutting tool sharp and clean. A prop­erly maintained tool, with sharp cut­ting edges reduces the risk of binding
and is easier to control.

Check for misalignment or bind-g.
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-

aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools. There is a
risk of bursting if the tool is damaged.

Use only accessories that are h.

identied by the manufacturer for
the specic tool model. Use of an

accessory not intended for use with

the specic tool model, increases the
risk of injury to persons.

Always use blades with correct i.
size and shape (diamond vs.
round) arbor holes. Blades that do

not match the mounting hardware of
the saw will run unpredictably, caus­ing loss of control.

Never use damaged or incorrect j.
blade washers or bolts. The blade

washers and bolt were specially
designed for your saw, to provide
optimum performance and safety of
operation.

When blade is binding, or when k.
interrupting a cut for any reason,
release the trigger and hold the
saw motionless in the material un­til the blade comes to a complete
stop. Never attempt to remove
the saw from the work or pull the
saw backward while the blade is in
motion or KICKBACK may occur.

Investigate and take corrective ac­tions to eliminate the cause of blade
binding.

Service

Tool service must be performed a.

only by qualied repair personnel.

When servicing a tool, use only b.
identical replacement parts. Use
only authorized parts.

Use only the lubricants supplied c.

with the tool or specied by the

manufacturer.
