SAFETY GUIDELINES
N
ote: 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.
• 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 before putting it down after use, in
the interest of safety and to prevent possible damage to the tool/user.
• K
eep proper footing at all times in order to ensure correct balance.
• 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 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 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 Clipped-Head Framing Nailer.
• Do not use the Air-powered Clipped-Head Framing Nailer for any task other than that it is designed to perform.
• Do not use the Air-powered Clipped-Head Framing Nailer unless it has been instructed to use.
• L
ocate the compressor in a well-ventilated area for cooling, at a minimum of
12" (31 cm) away from the nearest wall.
• P
rotect the air hose and the power cord from damage and puncture. Inspect
t
hem for weak or worn spots every week, and replace them if necessary.
• A
lways wear hearing protection when using the air compressor. Failure to do
so may result in hearing loss.
• D
o not carry the compressor while it is running.
• D
o not operate the compressor if it is not in a stable position.
• D
o not operate the compressor on a rooftop or an elevated position that
could allow the unit to fall or be tipped over.
• A
lways replace a damaged gauge before operating the unit again.

AIR-POWERED CLIPPED-HEAD FRAMING NAILER 058-8434-4
CAUTION!
Potential hazard that may result in moderate injury or damage to e
quipment.
• Always ensure that the tool has stopped before connecting it to the air
s
upply.
• D
o not wear watches, rings, bracelets, or loose clothing when using any air
tool.
• D
o 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, with missing or damaged parts, or that
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
lways 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. Floor should be kept clean and clear.
• Always follow all workshop safety rules, regulations, and conditions when
using the Air-powered Clipped-Head Framing Nailer.
• C
arry the tool by the handle only, keeping the finger away from the trigger.
Do not carry the tool by the hose, magazine or any other parts.
• D
o not use the tool near or below the freezing condition, as doing so may
cause tool failure.
• D
o not store the tool in a freezing environment to prevent ice formation on
the operating valves of the tool, as doing so may cause tool failure.
• H
andling 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.

GUIDELINES FOR PROPER USE AND OPERATION
Be sure to use a proper air compressor with Mastercraft
®
air-powered tools. The compressor should be able to supply a minimal air delivery of 6.63 SCFM @ 90 psi to ensure the compressor can run continuously with the Mastercraft Air-powered Clipped-Head Framing Nailer.
Features of the Clipped-Head Framing Nailer
• This lightweight Mastercraft® Air-powered Clipped-Head Framing Nailer drives 2 to 3 1/2" (50 to 90 mm) long clipped-head framing nails.
• It features
– a hardened one-piece piston and an open magazine designed for easy extraction of
jammed nails.
– a rubber grip handle for improved control and added comfort, even during extended use.
– a tool-free driving depth adjustment for driving nails flush or countersunk into various
materials, which keeps projects moving.
– additional trigger included to allow advanced bump-fire use.
– a rear-loading magazine made of extruded aluminum for lighter weight and added
durability.
– a 360º air deflector that can be pointed in any direction.
• The hardened claw tip reduces wear and limits slippage when the tool is driven at an angle.
• The rubber covers at the end of the magazine and on both the sides of the main body protect
both the operator and the workpiece.
• This framing nailer is ideal for construction framing, wall sheathing, roof sheathing, floor decking and similar applications.

IMPORTANT INFORMATION

AIR-POWERED CLIPPED-HEAD FRAMING NAILER 058-8434-4
Air system
•Always use clean, dry, regulated compressed air at 4 to 7 bar (60 to 100 PSI).
• Do not exceed the maximum and minimum pressures. Operating the tool at the wrong pressure will cause excessive noise, fast wear or misfiring.
• It is recommended that a filter-regulator-lubricator be used and be located as close to the tool
as possible.
• If a filter-regulator-lubricator is not installed, place up to 6 drops of compressor oil into the air inlet plug before each use.
• If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the air pressure to the tool, which will cause a reduction in power, efficiency, and general performance.
• For optimal performance, install a quick connector to the tool and a quick coupler on the hose, if applicable.
• Verify that all of the connections in the air supply system are sealed in order to prevent air from leaking.
N
ote: Please note that the filter-regulator-lubricator and air hose are sold separately.
