Safety
1. Always use impact type sockets that are designed for impact wrenches.
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.
Model # G3431
1/2” Impact Wrench
The air inlet, used for connecting 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
For removal of frozen nuts, soak nuts in penetrating oil and break rust seal before removing
with wrench. If nut does not start to move in three to five seconds, use a larger size impact
wrench. Do not use impact wrench beyond rated capacity as this will drastically reduce tool
life.
To remove nuts, set the regulator to the maximum setting. To install nuts, set the regular to
the minimum to medium setting. Do not over tighten the nuts.
WARNING: Do not use hand tool sockets (chrome), use impact quality sockets only. Hand tool
sockets can shatter and cause serious injury if used with air tools. Loose attachments, such as
extension bars, can cause serious injury.
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
Warning: Dust created by power sanding, sawing, grinding, drilling, and other activities
contains particles and chemicals known to cause cancer, birth defects or reproductive harm.
Some examples of these chemicals are:
⚫Lead from lead-based paints
⚫Crystalline silica from bricks, cement and other masonry products
⚫Arsenic and chromium from chemically treated lumber
To reduce your exposure to these chemicals, work in well ventilated areas with approved
safety equipment specially designed to filter out microscopic particles.
