Exposure to high noise levels can cause permanent, disabling hearing loss and other problems, such as tinnitus (ringing,
buzzing, whistling or humming in the ears). Therefore, risk assessment and the implementation of appropriate controls for
these hazards are essential.
Appropriate controls to reduce the risk may include actions such as damping materials to prevent work pieces from ”ringing”.
Use hearing protection in accordance with employer's instructions and as required by occupational health and safety regulations.
Operate and maintain the assembly power tool for mechanical fasteners as recommended in the instruction handbook, to
prevent an unnecessary increase in the noise level.
Select, maintain and replace the consumable/part as recommended in the instruction handbook, to prevent an unnecessary
increase in noise.
If the power tool has a silencer, always ensure that it is in place and in good working order when the power tool is being operated.

10. OPERATION INSTRUCTIONS
This pneumatic-hydraulic installation tool is well assembled and tested before delivery; however, the necessary setting and
testing are still strongly suggested before operating tool. Carefully read this OPERATION INSTRUCTIONS 10.2 - 10.5 to
check the setting of tool, follow the 10.6 OPERATION PROCEDURE to do the pilot test before operating tool.
The compressed air pressure should be in the suggested working range.The nose assembly size, lockbolt size, structural blind
rivet size and work pieces’ hole diameter must be well matched; the pilot test can verify the fastening work is correct or not.
1.
2.
10.1 SETTING AND TESTING
This pneumatic-hydraulic installation tool is operated with compressed air at an optimum air pressure of 90 psi or 6.2 bar.
This pneumatic-hydraulic installation tool is recommended to connect with COMPRESSED AIR SUPPLY SYSTEM (Fig. 1)
including air compressor, main air supply line, air preparation unit (air filter, air pressure regulator with gauge, air lubricator)
and air hose. These should be fitted within 3 meters or 10 feet from air pressure regulator to the tool to ensure maximum tool
life and minimum tool maintenance.
The air pressure regulator is used to adjust the operating air pressure not to exceed the maximum operating air pressure 100
psi or 7.0 bar.
The air hose should resist a minimum 150% of maximum operating air pressure (100 psi or 7.0 bar) produced in the
COMPRESSED AIR SUPPLY SYSTEM, that is to resist the highest air pressure 145 psi or 10 bar. The air hose should be oil
resistant, and have an abrasion resistant exterior. The air hose must have a minimum inner diameter of 3/8˝ or 10 mm. Be sure
to expel the accumulated dirt and water from air pipeline before connecting air hose to the tool.
1.

10.2 COMPRESSED AIR SUPPLY SYSTEM (Fig.1)
This pneumatic-hydraulic installation tool is designed to quickly fasten the work pieces together firmly with a suitable size
lockbolt or blind rivet by depressing the trigger (25) to suck the compressed air into the air cylinder (19), to activate the air
piston assembly (46AY) upwards, to drive hydraulic oil, to force the oil piston assembly (8AY) backwards, to drive the collet
assembly backwards to deform collar or rivet body and break off the pin or rivet mandrel with the minimum vibration, eventually
the work pieces are fastened together firmly. Above fastening process is completed in one second.
After setting lockbolt or blind rivet, release the trigger (25) to stop the fastening work, the powerful return springs (11 & 12)
push the oil piston assembly (8AY) and collet assembly forwards to drive hydraulic oil and to release spent pin or spent
mandrel, to push the air piston assembly (46AY) downwards to the original position, the air is therefore expelled from the air
cylinder (19) to the air exhaust through the noise silencer (21) with low noise. The fastening cycle is completed, and the tool is
ready for setting the next lockbolt or blind rivet.
When inserting the next same size lockbolt’s pin into the anvil insert of nose assembly, the spent pin is therefore pushed out
of tool through the pintail deflector (16).
While the spent mandrel of blind rivet can be cleared out of tool through the pintail deflector (16) by tilting nose assembly
upwards.
So that the spent pins or spent mandrels shall be not jammed in the tool after setting the next lockbolt or blind rivet.

10.4 EXCHANGE NOSE ASSEMBLY
Disconnect the tool from the compressed air supply system.
Choose the correct size nose assembly as the new working
nose assembly.
NOTE: The patented RIVET SIZE HOLE GAUGE Design™ at
the bottom of air cylinder end cap (49) provides a great
assistance for checking the rivet body diameter of the blind rivet
to be fastened. Insert rivet body into the holes to find out the
matched size (for example ★Ø3/16˝ or 4.8 mm) marked beside
the hole gauge, then choose the matched size nose assembly
(for example ★Ø3/16˝ or 4.8 mm) as the working nose
assembly, so as to avoid the spent mandrel being stuck in tool
after setting blind rivet (Fig. 2).
