SAFETY GUIDELINES
Note: Carefully read and understand all the instructions in this manual before using the tool. Ensure
that the operator has read and understood these instructions.
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.
• Keep air hose away from heat, oil, and sharp edges. Check air hose for
wear before each use and ensure that all connections are proper.
• Always ensure that the workpiece is firmly secured leaving both hands free
to control the tool.
• Always ensure that the tool has stopped before putting it down after use, for
safety purposes and to prevent possible damage to the tool/user.
• Keep proper footing at all times in order to ensure correct balance.
• 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 the 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 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
towards the user or other personnel.

• Risk for breathing: 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 the Air-powered
3-in-1 Nailer.
• Do not use the Air-powered 3-in-1 Nailer for any task other than that it is
designed to perform.
• Locate the compressor in a well-ventilated area for cooling, and 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 an elevated position that
could allow the unit to fall or be tipped over.
• Always replace a damaged gauge before operating the unit again.

CAUTION!
Potential hazard that may result in moderate injury or damage to
equipment.
• Always ensure that the tool has stopped before connecting to the air supply.
• Do not wear watches, rings, bracelets, or loose clothing when using any airpowered tool.
• Do not overload the tool. Allow the tool to operate at its optimum speed for
maximum efficiency.
• 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.
• For optimal safety and tool performance, inspect the tool daily in order to
ensure free movement of the trigger, safety mechanisms, and springs.
• Always keep your air tool clean and lubricated. Daily lubrication is essential
to avoid internal corrosion and possible failures.
• Ensure the floor is not slippery and wear non-slip shoes. Floors should be
kept clean and clear.
• Always follow all workshop safety rules, regulations, and conditions when
using the Air-powered 3-in-1 Nailer.
• Carry the tool by the handle only, keeping fingers away from the trigger. Do
not carry the tool by the hose, magazine, or any other parts.
• Do not use the tool near or below freezing point, as doing so may cause tool
failure.
• Do not store the tool in a freezing environment to prevent ice formation on
the tool’s operating valves, as doing so may cause tool failure.
• Handling and storage of oil: Use with adequate ventilation. Avoid contact of
oil with eyes, skin, and clothing. Avoid breathing spray or mist. Store in a
tightly closed container in a cool, dry, well-ventilated area free from
incompatible substances.

Note: Recycle unwanted materials rather than disposing of them as waste. Sort the tools, hoses, and
packaging in specific categories and take to the local recycling centre or dispose of in an
environmentally safe way.
CAUTION!
Potential hazard that may result in moderate injury or damage to
equipment.
• Disconnect tool from the air supply and turn off the
compressor before performing any maintenance or changing
accessories, when clearing a jammed fastener, when the
tool is not in use, when it is being handed to another
person, and when it is left unattended. Failure to comply
may result in moderate injury or damage to equipment.
• Use safety goggles and ear protection:
Wear safety glasses with side shields when operating the
tool/compressor and verify that others in the work area are
also wearing safety glasses. Safety glasses must conform to
American National Standards Institute (ANSI Z87.1)
requirements and must provide protection from flying
particles from the front and the sides.
Air-powered tools are loud and the sound can cause hearing
damage. Always wear ear protection to prevent hearing
damage and loss. Failure to comply may result in moderate
injury.
