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.
Model # G3440
4” Angle Grinder

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
The air regulator can be used as an air throttle for setting positive speed control. Turn the air
regulator lever up for maximum speed.
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.
WARNING: Make sure the RPM rating of the grinding discs correspond with the
manufacturer’s recommended speed of the tool.
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.
