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.
FITTINGS:
Install a male plug on the tool which is free flowing and which will release air pressure from the tool when disconnected
from the supply source.
HOSES:
Air hoses should have a minimum of 150 p.s.i. (10.6 kg/cm
2
) working pressure rating or 150 percent of the maximum
pressure that could be produced in the air system. The supply hose should contain a fitting that will provide “quick
disconnecting” from the male plug on the tool.
SUPPLY SOURCE:
Use only clean regulated compressed air as a power source for this tool. NEVER USE OXYGEN, COMBUSTIBLE
GASES, OR BOTTLED GASES, AS A POWER SOURCE FOR THIS TOOL AS TOOL MAY EXPLODE.
REGULATOR:
A pressure regulator with an operating pressure of 0 - 125 p.s.i. (0 - 8.79 KG/CM
2
) is required to control the operating
pressure for safe operation of this tool. Do not connect this tool to air pressure which can potentially exceed 200 p.s.i.
(14 KG/CM
2
) as tool may fracture or burst, possibly causing injury.
OPERATING PRESSURE:
Do not exceed recommended maximum operating pressure as tool wear will be greatly increased. The air supply must
be capable of maintaining the operating pressure at the tool. Pressure drops in the air supply can reduce the tool’s
driving power. Refer to “TOOL SPECIFICATIONS” for setting the correct operating pressure for the tool.
FILTER:
Dirt and water in the air supply are major causes of wear in pneumatic tools. This tool is equipped with an internal filter.
To maintain proper air flow the filter must be cleaned regularly. To clean the filter, remove the filter from the end cap
and use compressed air from a blow gun to blow the dirt from the filter.
An in-line 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.

OW TO CHANGE OPERATING MODES:
T
he LPF21PL is initially locked in the sequential trip operating mode. In order to enable the mode selection
feature, the mode locking pin must be removed as shown in FIG A.
B
e aware that once the mode locking pin is removed, the trigger is converted to a
selectable trigger, enabling either sequential trip or contact trip operating modes.
A
lways 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.
Selecting Contact Trip Mode: Refer to Fig A.
1
) Remove mode locking pin.
2) Push in pivot pin and hold.
3
) Rotate the selector 180 degrees counter-clockwise to
t
he contact trip position, while pushing in the pivot pin.
4) Ensure the selector is fully seated in the new position.
Always verify and be aware of tool operating
mode by inspecting the trigger before connecting
to an air supply and/or using the tool.
Selecting Sequential Trip Mode:
1) Remove mode locking pin (if installed).
2) Push in pivot pin and hold.
3) Rotate the selector 180 degrees clockwise to the
sequential trip position, while pushing in the pivot pin.
4) Ensure the selector is fully seated in the new position.
