a. Stay alert. Watch what you are do-

ing and use common sense when

operating the tool. Do not use the

tool while tired or under the inﬂu-

ence of drugs, alcohol, or medica-

tion. A moment of inattention while

operating the tool increases the risk

of injury to persons.

Tool use and care

a. Use clamps or another practical

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.

b. dress properly. do not wear loose

clothing or jewelry. Contain long

hair. keep hair, clothing and gloves

away from moving parts. Loose

clothes, jewelry, or long hair increas-

es risk of injury to persons as a result

of being caught in moving parts.

b. do not force the tool. Use correct

tool for application. The correct tool

will do the job better and safer at the

rate for which the tool is designed.

c. do not use the tool if the switch

does not turn the tool on or off.

Any tool that cannot be controlled

with the switch is dangerous and

must be repaired.

c. Avoid unintentional starting. Be

sure the switch is off before con-

necting to the air supply. Do not

carry the tool with your ﬁnger on the

Trigger or connect the tool to the air

supply with the switch on.

d. disconnect the tool from the air

source before making any adjust-

ments, 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.

d. do not overreach. keep proper

footing and balance at all times.

Proper footing and balance enables

better control of the tool in unexpect-

ed situations.

use safety equipment. A

dust mask, non-skid safety

shoes and a hard hat must

be used for the applicable

conditions. Wear heavy-duty work

gloves during use.

e. Store the tool when it is idle out of

reach of children and other un-

trained persons. A tool is dangerous

in the hands of untrained users.

Always wear eye protec-

tion. Wear ANSI-ap-

g. Check for misalignment or bind-

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.

b. Never use oxygen, carbon dioxide,

combustible gases or any bottled

gas as an air source for the tool.

Such gases are capable of explosion

and serious injury to persons.

Vibration precautions

Speciﬁc Safety Instructions

This tool vibrates during use. Re-

peated or long-term exposure to vibra-

tion may cause temporary or permanent

physical injury, particularly to the hands,

arms and shoulders. To reduce the risk of

vibration-related injury:

1. The warnings and precautions dis-

cussed in this manual cannot cover

all possible conditions and situations

that may occur. It must be under-

stood by the operator that common

sense and caution are factors which

cannot be built into this product, but

must be supplied by the operator.

1. Anyone using vibrating tools regu-

larly or for an extended period should

ﬁrst be examined by a doctor and

then have regular medical check-

ups to ensure medical problems are

not being caused or worsened from

use. Pregnant women or people

who have impaired blood circulation

to the hand, past hand injuries, ner-

vous system disorders, diabetes, or

Raynaud’s Disease should not use

this tool. If you feel any medical or

physical symptoms related to vibra-

tion (such as tingling, numbness, and

white or blue ﬁngers), seek medical

advice as soon as possible.

2. WARNING: The brass components

of this product contain lead, a chemi-

cal known to the State of California

to cause birth defects (or other repro-

ductive harm). (California Health &

Safety code § 25249.5, et seq.)

3. Only use with accessories rated to

handle forces exerted by tool during

operation. Other accessories not de-

signed for the forces generated may

break and forcefully launch pieces.

4. Attach all accessories properly to the

tool before connecting the air sup-

ply. A loose accessory may detach or

break during operation.

2. Do not smoke during use. Nico-

tine reduces the blood supply to the

hands and ﬁngers, increasing the risk

of vibration-related injury.

5. Obey the manual for the air compres-

sor used to power this tool.

3. Wear suitable gloves to reduce the

vibration effects on the user.

6. Install an in-line shutoff valve to allow

immediate control over air supply in

emergency, even if hose is ruptured.

4. Use tools with the lowest vibration

when there is a choice between dif-

ferent processes.

7. Use this tool with both hands only.

Using tools with only one hand can

result in loss of control.

5. Include vibration-free periods each

day of work.

8. Do not lay the tool down until it has

come to a complete stop. Moving

parts can grab the surface and pull

the tool out of your control.

6. Grip tool as lightly as possible (while

still keeping safe control of it). Let

the tool do the work.

9. Do not force the tool. Use a larger

one if needed.

7. To reduce vibration, maintain tool as

explained in this manual. If abnormal

vibration occurs, stop immediately.

1. Incorporate an in-line oiler, shut-off

valve, regulator with pressure gauge,

and ﬁlter for best service, as shown in

the diagram above. An in-line shut-

off valve is an important safety

device because it controls the air

supply even if the air hose is rup-

tured.

Note: For additional information regarding

the parts listed in the following pages,

refer to the Assembly Diagram near

the end of this manual.

unpacking

When unpacking, make sure that

the item is intact and undamaged. If any

parts are missing or broken, please call

Harbor Freight Tools at the number shown

throughout the manual as soon as pos-

sible.

Note: If an automatic oiler system is not

used, add a few drops of Pneumatic

Tool Oil to the airline connection be-

fore operation. Add a few more drops

after each hour of continual use.

• This air tool may be shipped with a

protective plug covering the air inlet.

Remove this plug before set up.

2. Attach an air hose to the compres-

sor’s air outlet. Connect the air hose

to the air inlet of the tool. Other com-

ponents, such as a connector and

quick coupler, will make operation

more efﬁcient, but are not required.

9. If the tool will not be used at this

time, turn off and detach the air sup-

ply, safely discharge any residual air

pressure, and release the throttle

and/or turn the switch to its off posi-

tion to prevent accidental operation.

WARNINg! TO pREVENT SERIOuS

INjuRY FROm ACCIdENTAl

OpERATION:

do not install a female quick

coupler on the tool. Such a coupler

contains an air valve that will allow

the air tool to retain pressure and

operate accidentally after the air

supply is disconnected.

Note: Residual air pressure should not be

present after the tool is disconnected

from the air supply. However, it is a

good safety measure to attempt to

discharge the tool in a safe fashion

after disconnecting to ensure that the

tool is disconnected and unpowered.

Note: Air ﬂow, and therefore tool perfor-

mance, can be hindered by under-

sized air supply components.

3. The air hose must be long enough

to reach the work area with enough

extra length to allow free movement

while working.

4. Make sure the tool’s throttle or switch

is in the off position; refer to Opera-

tion section for description of con-

trols.

5. Close the in-line safety valve be-

tween the compressor and the tool.

6. Turn on the air compressor according

to the manufacturer’s directions and

allow it to build up pressure until it

cycles off.

7. Adjust the air compressor’s output

regulator so that the air output is

enough to properly power the tool,

but the output will not exceed the

tool’s maximum air pressure at any

time. Adjust the pressure gradually,

while checking the air output gauge

to set the right pressure range.

8. Inspect the air connections for leaks.

Repair any leaks found.
