SERVICING PROCEDURES
1. Changing Nosepieces:
Hook up the tool to the air line and depress the lever. While
continuing to hold the lever down, use the maintenance tool to
remove the unwanted nosepiece and tighten the new nosepiece
in place again. When the lever is released and the tool is at rest, a
circular opening should be visible when looking through the
hydraulic section from the rear gland to the nosepiece.
2. Cleaning and Changing of the Jaws:
Disconnect the tool from the air line and then remove the head
with the maintenance tool. Hold the jaw housing coupler firmly
and remove the jaw housing. Clean the jaws with either a steel
brush or solvent. If excessive wear is apparent, replace them with
new jaws. Before reassembling, apply a thin coat of oil to the
sliding surface of the jaws. Reassemble the tool in the reverse
order while making sure that the chamfered end of the jaw pusher
is in contact with the jaws properly.
3. Jaw Opening Adjustment:
To obtain the maximum stroke of the tool, proper distance setting
between the jaw housing and the head is very important. First
loosen the lock nut. A rivet is then inserted into the nosepiece
which should be selected to match the rivet size to be set. While
screwing or unscrewing the head to achieve the minimum opening
of the jaws, check if the rivet mandrel can be removed and
inserted freely. Fasten the lock nut after the adjustment.
MAINTENANCE
1. Check the tightness of the connections between the jaw housing
coupler, nut, jaw housing, and the hydraulic plunger, the nosepiece,
the head and the lock nut.
2. If the jaws show excessive wear and/or are dirty, follow the steps
provided in the servicing procedures section.
AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool. Higher pressure (over 90
psig; 6.2 bar) raises performance beyond the rated capacity of the
tool, which will shorten tool life and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in the
air line will cause damage to the tool. Drain the water from air lines
and compressor prior to running tool. Clean the air inlet filter screen
weekly. The recommended hookup procedure can be viewed in FIG. 1.
The air inlet used for connecting air supply has standard 1/4" NPT.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D.
and fittings should have the same inside dimensions and be tightly
secured.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
LUBRICATION AND MAINTENANCE
Lubricate the air motor daily with high quality air tool oil. If no air line
oiler is used, run 1/2 oz. of oil through the tool. The oil can be squirted
into the tool air inlet or into the hose at the nearest connection to
the air supply, then run the tool. A rust inhibitive oil is acceptable for
air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
OPERATION
Always turn off the air supply, drain hose of air pressure and
detach tool from air supply before installing, removing or adjusting
any part or accessory on this tool, or before performing any
maintenance on this tool.
When the Lever/Trigger is depressed, the throttle valve is moved
down off its seat by the valve tube. Air enters the bottom of the air
cylinder, forcing the piston assembly up. As the piston assembly
rises, the plunger rod forces hydraulic fluid in to the upper part of
the hydraulic section, retracting the hydraulic plunger. Meanwhile,
the jaws grip the mandrel of the rivet, pulling until the rivet is set and
breaking the mandrel in the process.
When the lever is released, the throttle valve resets and shuts off the
air supply. The valve tube spring then lifts the valve tube and exhausts
the air throughout the hollow of the valve tube. The return spring
returns the hydraulic plunger to its original position. This opens the
jaws, releases the mandrel, and retracts the piston assembly back to
its original static site.
NOTE: During operation, safety goggles should always be worn to
guard against flying debris (users and bystanders).
