INSTRUCTION MANUAL
OPERATION
1. 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. As the
Piston Assembly rises, the Plunger Rod forces hydraulic fluid into 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.
2. When the Lever/Trigger 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 through the hollow of the
Valve Tube. The Return Spring returns the Hydraulic Plunger to its original position. This
open the Jaws, releases the mandrel, and retracts the Piston Assembly back to its original
static site.
SERVICING PROCEDURES
1.CHANGING NOSEPIECES
Hook up the tool to the air line and depress the Lever/Trigger. While continuing to the
Lever/Trigger down, use the Multi-Wrench to remove the unwanted Nosepiece and tighten
the new Nosepiece in place again. When the Lever/Trigger 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.CLEANINGAND CHANGING OF THE JAWS
Disconnect the tool from the air line and then remove the Head with the Multi-Wrench. 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 OPENINGADJUSTMENT
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.
DAILY CARE
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.
MALFUNCTION & REPAIR
A. Rivet mandrel is gripped by the jaws but the rivet can not be set and mandrel can not be
broken
CAUSE : Low air pressure or loss of hydraulic fluid.
REMEDY : Increase air pressure to 7 bar ( 100 PSI ) maximum at tool. Make sure all fitting
including Rear Gland and Head are tightened. If malfunction persists, add
hydraulic fluid as follows:
Loosening the Lock Nut slightly and turn the tool upside down. Disassemble
Air Cylinder Body from the Hydraulic Section and remove the Head. Next,
make sure that the Hydraulic Plunger is at the bottom of its stroke. If it must
be pulled to the bottom of its stroke, replace the Return Spring.
Before adding hydraulic fluid, also check to see if any leaks appear in the Air
Cylinder Body, Head or Rear Gland, If fluid is found in any of these areas ,
replace the appropriate O-Rings . Pour hydraulic fluid slowly into the
Hydraulic Section until the fluid level reaches the top of the Hydraulic Rod
Guide. Wait a few seconds to allow any air bubbles to escape.
Reassemble the tool in reverse order. Use extreme care to avoid damage to
O-Rings. A good rubber lubricant must be applied on the bearing surfaces of
Plungers and cylinder bores before re-assembly . A slow rotational movement
coupled with gentle pressure will aid in reinserting the Plungers.
NOTE: To achieve proper fluid level, Head must be removed when refilling.
Use proper hydraulic fluid
for the best performance of the tool.
B. Mandrel dose not fit completely into Nosepiece or fails to eject
CAUSE : A. Jaw Housing distance incorrect.
B. Jaws are dirty or damaged.
C. Fatigued Jaw Pusher Spring.
D. Fatigued Return Spring.
E. Air leakage in vacuum system.
REMEDY : A. Loosen the Head and check the rated stroke length. If shorter, search for
worn or damaged O- Rings and replace it.
B. Clean or replace the Jaws.
C. Replace the Jaw Pusher Spring.
D. Replace the Return Spring.
E. Search for worn or damaged seals in the vacuum system and replace it.
C. Tool take more than one stroke under ideal conditions to set rivet and break mandrel
CAUSE : A. Insufficient hydraulic fluid.
B. Low air pressure.
C. Loose Nosepiece or improper size of Nosepiece.
D. Rivet Body too long for the thickness of the joint.
REMEDY : A. See Remedy under MALFUNCTION & REPAIR A.
B. Increase air pressure but do not exceed 7 bar ( 100 PSI ) at tool.
C. Tighten Nosepiece or use right size of Nosepiece.
D. The Rivet Body should be 3-6 mm longer than the thickness of the joint.

General preparation and connection:
1. Before connecting the air hose, apply 4 to 5 drops of SAE 10W-20 (ISO Viscosity Grade 46/32) Hydraulic Oil at the air inlet. Also, every
3 to 4 hours of operation, oiling is necessary. Twist Teflon thread tape to ensure a proper seal air inlet. Then tighten the air coupler into
air tool.
2. The supplied compressed air must be clean and dry, with the appropriate oil mist. Use an air treatment unit; filter, regulator and
lubricator.
3. Please refer Fig.1 illustration shows the correct mode of connection to the air supply system which will increase the efficiency and useful
life of the tool.
4. The quick connect coupling and hose must have sufficient air flow capacity. We recommend an air hose with a diameter of 10mm (3/8”).
5. To ensure a good performance. The operation pressure at the compressed air inlet should not exceed 6.3bar (90psi) (unless indicated
otherwise). Higher operating pressures may cause damaged or excessive wear. Operating pressures below 5.3bar may cause pressure
or power loss.
Risk of injury
