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 this tool in the presence of flammable liquids or gases. Sparks
that are created during use may ignite gases.

• D

o not point the tool toward yourself or other people. Keep hands, feet and

all other parts of the body clear from work area.

• A

lways ensure that the workpiece is firmly secured, leaving both hands free

to control the tool.

• A

lways ensure that the tool has stopped after use, for safety purposes and

to prevent possible damage to the tool/user.

• Do not use oxygen or any other combustible or bottled
g

as to power air-powered tools. Failure to observe this
warning can cause explosion and serious personal injury
or death. Use only compressed air to power air-powered
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 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.

• 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 people.

• Breathing risk: 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 the 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.

• D

o not use the tool if it is leaking air, has missing or damaged parts, or if it

requires repairs. V

erify that all screws are securely tightened.

• For optimal safety and tool performance, i

nspect the tool daily in order to

ensure free movement of the trigger, safety mechanisms and springs.

• A
