SAFETY GUIDELINES

DANGER!

Potential hazard that will result in serious injury or loss of life.

• Keep children away from the work area. Do not allow children to handle
power tools.

• Do not use a tool that is leaking air, that has missing or damaged parts, or
that requires repairs. Verify that all screws are securely tightened.

• Never attempt to override tool safety features.

• Do not use oxygen or any other combustible or bottled
gas to power air-powered tools. Failure to observe this
warning can cause explosion and serious personal injury
or death. Use only the compressed air to power air­powered tools. Use a minimum of 25' (7.6 m) of hose to
connect the tool to the compressor. Failure to comply will
result in serious injury or loss of life.

• Risk of electric shock: Do not expose a compressor to rain. Store it indoors.

Disconnect the compressor from the power source before servicing.
Compressor must be grounded. Do not use grounding adaptors.

• Risk of personal injury: Do not direct compressed air from the air hose
toward the user or other personnel.

• Risk of inhallation: Never directly inhale the air produced by the compressor.

• Risk of bursting: Do not adjust the pressure switch or safety valve for any

reason. They have been preset at the factory for this compressor’s maximum
pressure. Tampering with the pressure switch or the safety valve may cause
personal injury or property damage.

• Risk of burns: The pump and the manifold generate high temperatures. In
order to avoid burns or other injuries, do not touch the pump, the manifold,
or the transfer tube while the compressor is running. Allow the parts to cool
down before handling or servicing. Keep children away from the compressor
at all times.

• Risk of bursting: Make sure the regulator is adjusted so
that the compressor outlet pressure is set lower than the
maximum operating pressure of the tool. Before starting
the compressor, pull the ring on the safety valve to make
sure the valve moves freely. Drain water from tank after
each use. Do not weld or repair tank. Relieve all pressure
in the hose before removing or attaching accessories.

WARNING!

Potential hazard that could result in serious injury or loss of life.

•

Do not allow unskilled or untrained individuals to operate an Air-powered
Right Angle Die Grinder or any other air-powered tool.

• Always ensure that the workpiece is firmly secured leaving both hands free
to control the tool.

• Always keep your air tool clean and lubricated. Daily lubrication is essential
to avoid internal corrosion and possible failure.

• Do not overload the tool. Allow the tool to operate at its optimum speed for
maximum efficiency. Excessive overload can cause the tool casing to split,
and may also lead to excessive wear on moving parts and possible failure.

• Use only the lightweight coil hoses for connecting the tool to the
compressor coupling. Do not fit quick-change couplings onto the tool, as the
vibration can lead to damage or failure of the coupling.

• Always ensure that the tool has stopped before connecting it to the air
supply.

• Always ensure that the accessories are rated/designed for use with the tool.

• Ensure that the accessories are correctly and securely fastened before
connecting the tool to the air supply. Failure to comply could result in

serious injury or loss of life.

• Locate the compressor in a well-ventilated area for cooling, at a minimum of
12" (31 cm) away from the nearest wall.

• Protect the air hose and the power cord from damage and puncture. Inspect
them for weak or worn spots every week, and replace them if necessary.

• Always wear hearing protection when using the air compressor. Failure to do
so may result in hearing loss.

• Do not carry the compressor while it is running.

• Do not operate the compressor if it is not in a stable position.

• Do not operate the compressor on a rooftop or in an elevated position that
could allow the unit to fall or be tipped over.

• Always replace a damaged gauge before operating the unit again.
