Air Supply And Connections - Bostitch P50 Serie Manual De Operación Y De Mantenimiento

AIR SUPPLY AND CONNECTIONS

Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.
Always disconnect air supply: 1. Before making adjustments; 2. When servicing the tool;
3. When clearing a jam; 4. When tool is not in use; 5. When moving to a different work area,
as accidental actuation may occur, possibly causing injury.
The air supply system must be capable of maintaining the required air pressure at the tool
when it is operated at its highest cycle speed. Inadequate air supply will result in a loss
of power and inconsistent driving after the first cycle when the tool is operated in high
speed bursts.
Always attach a free-flow connector plug to the plier. If a wrong fitting is used, the tool can remain
charged with air after disconnecting, and thus will be able to cycle even after the air line is unplugged.
NOTE: Air compressors used to supply compressed air to this plier should comply with the
requirements of the American National Standards Institute Standard B19.3, Safety Standard for
Compressors for Process Industries.
NOTE: Make sure air lines and fittings are clean before connecting.
OPERATING PRESSURE:
The operating pressure of the P50 series plier is 30 to 55 p.s.i. (2.1 to 3.9 kg/cm
Do not exceed 55 p.s.i. (3.9 kg/cm
SETTING THE CORRECT PRESSURE:
The air requirements will vary, depending on the material to be stapled and the staple size. Do not use more
air pressure than is required to drive the staple in the specific job. To determine best setting, start at low
pressure and increase pressure until drive is satisfactory. Using excess pressure increases tool wear on the
plier and wastes compressed air.
QUICK DISCONNECT FITTINGS:
Install a free-flow connector plug on the nailer. Thread is 1/4" N.P.T. Install a
connector socket on the air hose. For best performance, fitting should have
minimum inside diamater. of .190".
REGULATORS:
Most air supply equipment will produce pressures that exceed the P50's maximum operating pressure, 55 p.s.i.
(3.9 kg/cm ). A pressure regulator is required to control the operating pressure. The flow capacity must be
2
sufficient for the air usage at the installation.
HOSES:
Air supply hoses should have a 85 p.s.i. (6.0 kg/cm
pressure that could be produced in the air system.)
AIR CONSUMPTION:
The P50 requires 1.75 cubic feet per minute of free air to operate at the rate of 100 staples per minute, at 55
p.s.i. Take the actual rate at which the plier will be run to determine the amount of air required. For instance, if
your staple usage averages 50 staples per minute, you need 50% of the 1.75 c.f.m. which is required for
running at 100 staples per minute.
FILTER:
Dirt and water in the air supply are major causes of wear in pneumatic tools. A filter will help to get the best
performance and minimum wear from the tool. The filter must have adequate flow capacity for the specific
installation. The filter has to be kept clean to be effective in providing clean compressed air to the tool. Consult
the manufacturer's instructions on proper maintenance of your filter. A dirty and clogged filter will cause a
pressure drop which will reduce the tool's performance.
