MAC TOOLS MPH1911 Manual De Funcionamiento Y Mantenimiento página 6

• The use of a hose whip is recommended. A coupler connected directly to the air inlet increases tool bulk
and decreases tool maneuverability.
• For maximum performance, the coupler on the wall should be the next size larger than the coupler used on
the tool. The coupler closest to the tool should not be less than the proper air supply hose size.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the
work by hand or against the body is unstable and can lead to loss of control.
• When not in use, disconnect tool from air supply to prevent accidental or unauthorized use in the absence
of the operator.
• Do not alter any part/component/accessory of this tool in any way.
• Mesh air strainer at air inlet occasionally becomes clogged with debris, blocking air supply, and decreasing
the tool's performance. If this occurs the mesh air strainer needs to to be cleaned.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Place the tool on the work surface before starting the tool. Do not point or indulge in any horseplay with
this tool.
• When cutting off, the workpiece shall be supported such that the slot is kept at constant or increasing
width during the complete operation.
• If the bit becomes jammed in a cut slot, shut off the hammer and ease the bit free. Check that the bit is
still correctly secured and not damaged before continuing the operation.
4) SERVICE
• Tool service must be performed by qualified repair personnel, using only Mac Tools authorized, identical
replacement parts. Use only lubricants recommended by Mac Tools.
ADDITIONAL SPECIFIC SAFETY RULES FOR AIR HAMMERS
• lnspect the bit before use. Do not use bits which (possibly) have been dropped or which are chipped,
cracked or otherwise defective.
• Ensure that the bit is correctly mounted and tightened before use and run the saw at no-load speed for at
least 1 min in a safe position; stop immediately if considerable vibration or other defects are detected and
determine the cause of these defects.
• When chipping or scaling in potentially explosive environment, use spark resistant chisels (usually made of
beryllium copper).Consult the tool manufacturer before using tool in this manner.
• Use only chisels, scalers or other attachments suitable for use with impacting tools.
• Do not use tool without chisel retainer being properly secured to tool.
• Chisels that are worn or blunt at the cutting edge or shank should not be used as such conditions promote
tool breakage, reduce efficiency and increase vibration. A chisel which breaks can cause injury by creating
unexpected movement.
• Do not store chisels at 32°F (0°C) or lower temperatures. Freezing temperatures can make hardened
steels brittle, which can cause breakage and lead to injury.
• Do not run tool unless steel/chisel/needles are in contact with the working surface. Running tool without
steel/chisel/needles in contact with working surface can damage tool and chisel retainer.
• The tool's power is controlled by the pressure exerted on the trigger, firmly grip the tool and squeeze the
trigger to operate.
