Safety Instructions:
Please read the following instructions carefully.
Never dissemble the tool without reading the following safety instructions.
Always use the tool in accordance with the specified safety instructions. Direct any
queries regarding safety and operation to our company.
Never connect the tool to any medium other than compressed air. Set the air pressure
between 42 to 101 psi.
Do not use the tool for purpose other than installing rivets.
The tool must be maintained in a safe working condition at all times and examined at
regular intervals for damage.
Do not dismantle this tool without prior reference to the maintenance and service
instructions.
Always disconnect the air pipe from the tool inlet before maintenance and service.
Do not point tool towards people or persons.
When using the tool, wear safety glasses.

Tool Preparation:
The tool must be connected to an air filter. This unit filters the compressed air to separate dirt
and condensate. A pressure regulator with a preferred setting of 87 psi must be installed. Air
supply must be free of moisture and particles.
Use dry and clean materials (hose, couplings, fittings, etc.) to connect the tool to the filter.
Check for leakage in the compressed air supply. If here is leakage, replace the damaged hoses
or coupling. Drain the condensate from the filter. Also check the dirt filter.
Check the compressed air supply pressure. The tool must be fitted with correct nosepiece (01)
and pusher (07) before operating.

Operating Instruction:
1. Connect the air supply, switch ON/OFF vale (48) to ON position. (See figure 1)
2. Adjust the vacuum security system clockwise or counter-
clockwise. Air suction will allow the rivet to be held in any orientation.
(See figure 2)
Attention: If you don’t want to use vacuum system, you can turn
vacuum security system clock wise and turn it off.
3. Direct the riveter with rivet to the hole and then pull the trigger. The stems
automatically reverse to the collector and the rivet is set.

Priming:
After 100,000 cycles, the stroke is reduced and rivets are not set by one operation, then the
tool needs to be oiled. Please use the attached bottle of lubrication oil in the box.
1. Disconnect air supply to tool and switch ON/OFF valve (48) to OFF position.
2. Remove seal screw (84) and seal (83). (See figure 3)
3. Screw the priming pump oil into the bleed screw hole.
Press down and release several times until resistance is felt.
(See figure 4)
4. Remove the priming pump and the excessive oil will
flow out. Clean out the excessive oil and replace the seal
screw and seal.

Head Cleaning and Oiling:
Every 10,000 cycles the tool should be oil on the jaws. (See figure 5)
1. Disconnect air supply and air valve switch.
2. Dismantle the riveter head by wrench.
3. Use wrench to disassemble head components and cleaning these parts, and then
lubricate them before assembling. (See figure 5)
Trouble Shooting
Symptoms
Possible Causes
Solutions
The jaws cannot release the
mandrel
The nosepiece, jaws, jaw
carrier and out cylinder
may not be assembled
correctly
The spring may be worn
out or broken
The oil may be insufficient
There is oil or air leakage
somewhere
Check the nosepiece,
jaws, jaw carrier and out
cylinder
Replace the defective
coupling and components
Add hydraulic oil
The rivet cannot be put into
the tool nosepiece
The stem may be
obstructed
The vacuum system may
not be in good condition
Check the jaws
Adjust the vacuum
security system to the
optimal volume
The tool works very slowly or
requires more than one
trigger-pull to set the rivet.
Hydraulic oil level is low
The air pressure is low
The nosepiece is filled
with dust and particles
Add hydraulic oil
Adjust air pressure to the
specific range
Clean and oil
