Safety
1. Always wear approved eye protection.
2. Have throttle in “off” position when connecting to air supply.
3. Disconnect tool before performing service, changing accessories, or when not in use.
4. Always be in a safe working distance from others when using tools.
5. Keep tools clean and oiled for best and safest performance.
6. Follow instructions for lubricating and changing accessories.
7. Do not wear loose fitting clothing and remove watches and rings.
8. Always use proper hose and fittings. Never use quick change couplings attached at tool.
9. Keep proper footing and balance at all times.
10. Never carry tools by the hose. Keep hoses from heat, oil, and sharp edges. Check hoses
for weak or worn condition before each use, making certain that all connections are
secure.
Lubrication
Lubricate the tool daily with a good grade of air tool oil. The oil can be applied directly into
the air inlet of the tool and then run the tool. A rust inhibitor oil is acceptable for air tools.
Air Supply
Tools of this class operate on a wide range of air pressure. It is recommended that air pressure
of these tools measure 90 PSI at the tool while running free. Higher pressure and unclean air
will shorten the tool’s life and may create a hazardous condition.
Water in the airline will cause damage to the tool. Ensure that the air tank is drained daily
Clean the air inlet filter screen on at least a weekly basis. The recommended hookup
procedure can be viewed in the illustration below.

3/8” Reversible Pistol Grip Drill
with Comfort Handle Grip

The air inlet, used for connecting the air supply, has standard 1/4” NPT American Thread.
Line pressure should be increased to compensate for unusually long air hoses (over 25 feet).
Minimum hose diameter should be 1/4” I.D. and fittings should have the same inside
dimensions.
Operating Instructions
Locate the center of the hole to be drilled by using a center punch. Place drill bit tip in punch
mark. Hold drill square to the work piece and start motor. Apply steady, even pressure. Do not
force. Too much pressure can cause bit to break or over heat and can cause personal injury.
Too little pressure will keep bit from cutting and cause it to overheat.
If the drill jams in the work, release the throttle immediately. Disconnect the drill before
removing bit. Do not attempt to free the bit by starting and stopping the motor. When
changing bits, always disconnect the tool from the air line. A faulty start can cause personal
injury.
The air inlet used for connecting air supply has standard 1/4” NPT thread. Have throttle in “off”
position when connecting to air supply. Disconnect tool before performing service, changing
accessories and when not in use. Always use tool at a safe distance from other people in the
work area.
Maintenance
Other factors outside the tool may cause loss of power or erratic action. Reduced Compressor
output, excessive drain on the air line, moisture or restriction in air lines or the use of hose
connections of improper size or poor condition may reduce air supply. Dirt or gum deposits in
the tool may cut power. This may be corrected by cleaning the air strainer and flushing out
the tool with gum solvent oil. If outside conditions are in order and tool is out-of-warranty,
clean, reassemble, and re-lubricate, or take tool to any air tool service center. For tools in
warranty period, send tool direct to Warranty Center.

Notice
90% of all Air Tool problems are caused by moisture in air lines
This problem can be avoided by using Air Tool Lubricant (See
“Lubrication” & “Air Supply” section of this manual)
FAILURE TO OIL can void your warranty
