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.

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.

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.
