InStRuctIOnS.  
This tool vibrates during use.  
Repeated or long-term exposure to  
vibration may cause temporary or  
permanent physical injury, particularly to  
the hands, arms and shoulders. To reduce  
the risk of vibration-related injury:  
1. Anyone using vibrating tools regularly  
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,  
nervous system disorders, diabetes,  
or Raynaud’s Disease should not  
use this tool. If you feel any medical  
or physical symptoms related to  
vibration (such as tingling, numbness,  
and white or blue fingers), seek  
medical advice as soon as possible.  
2. Do not smoke during use. Nicotine  
reduces the blood supply to the  
hands and fingers, increasing the risk  
of vibration-related injury.

and filter for best service, as shown  
in the diagram above. An in-line  
shutoff valve is an important  
safety device because it controls  
the air supply even if the air hose  
is ruptured. (See Fig. 2.)  
5. Close the in-line safety valve between  
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.  
note: If an automatic oiler system is not  
used, add a few drops of Pneumatic  
Tool Oil to the airline connection  
before operation. Add a few more  
drops after each hour of continual  
use. Oiling location is engraved into  
the bottom of the handle next to the  
drill’s air inlet.  
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.  
2. Attach an air hose to the  
compressor’s air outlet. Connect  
the air hose to the air inlet of the  
tool. Other components, such as  
a connector and quick coupler, will  
make operation more efficient, but  
are not required.  
8. Inspect the air connections for leaks.  
Repair any leaks found.  
9. If the tool will not be used at this  
time, 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 to prevent accidental  
operation.

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  
performance, can be hindered by  
undersized 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.

3. When drilling wood, place the bit  
at the point to be drilled. If you are  
drilling a hard, smooth surface, use  
a punch to mark the drill location.  
Grasp the drill firmly with both hands  
while slowly squeezing the Trigger  
(8). Never force the tool. Only apply  
light pressure when horizontal drilling.  
8. Securely clamp your workpiece.  
Work piece and Work Area Set up  
1. Designate a work area that is clean  
and well-lit. The work area must not  
allow access by children or pets to  
prevent injury and distraction.  
Note: When drilling plastics or plastic coated  
chip board, follow the same directions  
as stated in number 9 for wood.  
2. Route the air hose along a safe  
route to reach the work area without  
creating a tripping hazard or exposing  
the air hose to possible damage.  
The air hose must be long enough  
to reach the work area with enough  
extra length to allow free movement  
while working.  
Note: If a bit becomes wedged into the  
workpiece, remove it from the drill  
and use the appropriate hand tools to  
remove it.  
4. When drilling metal, always use a  
punch to mark the drilling position.  
Use a cutting oil with most metals, to  
prolong the life of the bit and increase  
the drilling action. With steel, tin, and  
sheet metal use a light machine oil,  
with aluminum, use paraffin. Do not  
use lubricants with brass, copper, and  
cast iron. Grasp the drill firmly with  
both hands and follow the directions  
given in #9 above.  
3. Secure loose workpieces using a vise  
or clamps (not included) to prevent  
movement while working.  
4. There must not be hazardous objects  
(such as utility lines or foreign  
objects) nearby that will present a  
hazard while working.  
general Operating Instructions  
1. If an automatic oiler is not used, add  
a few drops of Pneumatic Tool Oil  
to the airline connection before use.  
Add a few drops more after each  
hour of continual use.  
5. When done drilling, release pressure  
on the Trigger (8). The drill will slow  
to a stop. Disconnect the Air Drill  
from the air compressor hose.  
6. To prevent accidents, turn off the  
tool, detach the air supply, safely  
discharge any residual air pressure in  
the tool, and release the throttle and/

high quality and durability standards, and warrants to the original purchaser that  
this product is free from defects in materials and workmanship for the period of one  
year from the date of purchase (90 days if used by a professional contractor or if  
used as rental equipment). This warranty does not apply to damage due directly or  
indirectly, to misuse, abuse, negligence or accidents, repairs or alterations outside  
our facilities, normal wear and tear, or to lack of maintenance. We shall in no event be  
liable for death, injuries to persons or property, or for incidental, contingent, special  
or consequential damages arising from the use of our product. Some states do not  
allow the exclusion or limitation of incidental or consequential damages, so the above  
limitation of exclusion may not apply to you. THIS WARRANTY IS ExPRESSLY IN  
LIEU OF ALL OTHER WARRANTIES, ExPRESS OR IMPLIED, INCLUDING THE  
WARRANTIES OF MERCHANTABILITY AND FITNESS.  
To take advantage of this warranty, the product or part must be returned to us  
with transportation charges prepaid. Proof of purchase date and an explanation of the  
complaint must accompany the merchandise. If our inspection verifies the defect, we  
will either repair or replace the product at our election or we may elect to refund the  
purchase price if we cannot readily and quickly provide you with a replacement. We will  
return repaired products at our expense, but if we determine there is no defect, or that  
the defect resulted from causes not within the scope of our warranty, then you must  
bear the cost of returning the product.  
This warranty gives you specific legal rights and you may also have other rights  
which vary from state to state.
