Problem: Possible Cause: Corrective Action:
1) Trigger can not be
depressed.
Trigger safety is in the way. Turn the trigger safety to the side.
Warning: Do not remove or tamper with the trigger safety. It is there to
prevent accidental ring.
2) Stapler res but does
not shoot staples.
2. Air pressure is too low. Make sure staples are loaded correctly in the stapler (Fig. 7).
Adjust the regulator to increase output air pressure.
The optimum air pressure range for each stapler may vary. It also de-
pends on the type of wood one is stapling into.
Warning: Do not exceed maximum operating pressure of 105 psi.
Note: Most air compressors have two gauges: one gauge displays
the tank pressure and the other indicates the stepped down output air
pressure. After turning on the air compressor, wait until the air compres-
sor cuts off and the tank gauge stabilizes, then adjust the regulator. Set
initial air pressure to 70 psi and increase by 5 lb. increments until correct
pressure is achieved.
Caution: A faulty gauge or regulator may give incorrect pressure reading.
The only way to test this is to replace the gauge and/or the regulator.
3. Worn or cracked washer. Open the stapler magazine cover, remove the staples and shoot the
stapler several times while the magazine cover is open. If the piston
blade does not retract fully (totally disappears into the stapler body) at the
end of the cycle, it is very likely that the washer is worn and need to be
replaced. See How to Replace Washer or call Rowley Company.
4. Stapler has an air leak. Listen carefully for any air leak from the stapler. If air leak is detected from
air inlet plug, unscrew the inlet plug, wrap a strip of Teon® sealing tape
around the threads, screw in the inlet plug. If air leaks from other parts of
the stapler, call Rowley Company for further information.
Note: A burst of air follows each shooting cycle. This is normal.
5. Damaged piston. A damaged piston blade often damages the bumper.
Replace both (See How to Replace Piston and
Bumper), or call Rowley Company.
3) Stapler does not fully
drive staples.
1. Air pressure is too low. See corrective action for problem (2).
4) Piston blade appears
stuck, or sticking out of
the nose when not shoot-
ing, or stapler cycles
sluggishly.
1. Stapler does not have
adequate lubrication.
Add 2 drops of pneumatic lubricating oil through the stapler air inlet, or
install an in line lubricator and make sure the oil level in the lubricator is
adequate.
Note: Add one to two drops of oil at the start of each work day.
5) Stapler drives the
staples too deep and/
or damages the stapling
surface or cuts fabric or
make the fabric appear
buckled.
1. Operator presses the
stapler too rmly against the
stapling surface.
Unlike an electrical stapler, one does not need to and should not hold the
stapler rmly against the stapling surface. Rest the stapler nose lightly on
the stapling surface, then press the trigger. If the staples are still too deep,
tilt the stapler slightly, so stapler nose is at an angle from the stapling
surface.
Caution: Pressing hard on the stapler will not only damage the stapling
surface but could also damage the stapler piston and shorten the stapler
life.
