This pneumatic-hydraulic installation tool is designed to be driven by the appropriate compressed air pressure for quickly
fastening the work pieces together firmly with a suitable size lockbolt, or with a structural blind rivet on one-side work. The work
pieces to be fastened are various, such as metals, concrete, wood, plastic, leather, canvas and more. The Forged Aluminum
Alloy Hydraulic Cylinder has super strength and excellent durability. The applications are widely used in the production and
repairs of aircraft, automobiles & vehicles, boats, building construction, electric/electronic appliances, etc.
This pneumatic-hydraulic installation tool is designed and produced primarily for the professional users, the non-professional
users must read the operation manual thoroughly, and consult the manufacturer, authorized local agent or distributor for real
understanding. A half hour long hands-on training session with qualified personnel is essential and strongly recommended
before using this tool.

WARNING
3.1 SAFETY PRECAUTIONS

2
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.

3.7 NOISE HAZARDS
Disconnect the assembly power tool from the energy source when changing parts or accessories.
Be aware that failure of the work pieces or accessories or even of the parts itself can generate high-velocity projectiles.
Always wear impact-resistant eye protection during operation of the tool. The grade of protection required should be assessed
for each use.
The risks to others should also be assessed at any time.
Ensure that the work pieces are securely fixed.
Check that the means of protection from ejection of fastener and/or stem is in place and is operative.
There is possibly forcible ejection of installation mandrels from the front of the assembly power tool.

3.2 PROJECTILE HAZARDS
Use of the tool can expose the operator's hands to hazards, including crushing, impacts, cuts and abrasions and heat. Wear
suitable gloves to protect hands.
Operators and maintenance personnel shall be physically able to handle the bulk, weight and power of the tool.
Hold the tool correctly; be ready to counteract normal or sudden movements and have both hands available.
Maintain a balanced body position and secure footing.
Release the start-and-stop device in the case of an interruption of the energy supply.
Use only oils and lubricants recommended by the manufacturer.
Avoid unsuitable postures, as it is likely for these positions not to allow counteracting of normal or unexpected movement of the tool.
If the assembly power tool is fixed to a suspension device, make sure that the fixation is secure.
Beware of the risk of crushing or pinching if nose equipment is not fitted.

3.3 OPERATING HAZARDS
When using an assembly power tool, the operator can experience discomfort in the hands, arms, shoulders, neck or other
parts of the body.
While using an assembly power tool, the operator should adopt a comfortable posture whilst maintaining a secure footing and
avoiding awkward or off-balance postures. The operator should change posture during extended tasks; this can help avoid
discomfort and fatigue.
If the operator experiences symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness,
burning sensations or stiffness, these warning signs should not be ignored. The operator should tell the employer and consult
a qualified health professional.

3.
3.4 REPETITIVE MOTIONS HAZARDS
Disconnect the assembly power tool from the energy supply before changing the part or accessory.
Use only sizes and types of part, accessories and consumables that are recommended by the manufacturer of assembly
power tool; do not use other types or sizes of accessories, parts or consumables.
1.
2.
3.5 PART AND ACCESSORY HAZARDS
Slips, trips and falls are major causes of workplace injury. Be aware of slippery surfaces caused by use of the tool and aware
of trip hazards caused by the air line or hydraulic hose.
Proceed with care in unfamiliar surroundings. There can be hidden hazards, such as electricity or other utility lines.
The assembly power tool is not intended for use in potentially explosive atmospheres and is not insulated against contact with
electric power.
Ensure that there are no electrical cables, gas pipes, etc., which can cause a hazard if damaged by use of the tool.

3.6 WORKPLACE HAZARDS

3
The tool must be checked and maintained in a safe working condition at all times.
Do not use the tool outside the intent of design and use.
Do not dismantle the tool without prior reference to this manual.
Any modification to the tool and tool parts shall be prohibited.
Always use original spare parts to ensure safe operation and satisfactory performance.
Be sure to disconnect the tool from air supply before attempting to adjust, change nose assembly or dismantle tool’s parts.
For safety work, the operator and other persons in the vicinity are always required to wear the safety goggles to protect against
spent pin or mandrel ejection.
Be sure to adopt a firm footing or stable position before and during operating the tool.
Do not point the tool towards any person(s) or operator.
Do not operate the tool without firmly installing the nose assembly, adapter (2), retaining nut (1) and the pintail deflector (16).
Do not operate the tool without firmly locking the oil screw plug & sealing washer (7 & 6), noise silencer lock nut (22), valve
end cap (42), air cylinder end cap (49) and air inlet end cap (51).
Be sure to install the correct and recommended nose assembly for perfect installation of lockbolt or structural blind rivet.
The Operating Air Pressure shall not exceed 7.0 bar or 100 psi.
Excessive priming of hydraulic oil in the tool should be avoided.
After setting each lockbolt, to insert the next same size lockbolt’s pin into the anvil insert of nose assembly, and the spent pin
is therefore pushed out of tool through the pintail deflector (16).
After setting each blind rivet, the spent mandrel 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.
Take care to ensure the pin’s/mandrel’s sharp end and spent pins/mandrels are not to create any hazards.
Ensure that noise silencer (21) and vent holes do not become blocked or covered, and that air hose is always in good condition.
Always keep the tool and grip (55) dry and clean for the best possible grip and operation.
Take care to avoid entanglement of loose clothes, ties, long hair, cleaning rags, etc. in the moving parts of the tool.
When carrying the tool from place to place, always keep hands away from the trigger (25) to avoid inadvertent start up.
Take care to use the tool. Do not drop the tool. Do not use the tool as a hammer or other uses that will damage and wear the tool.
The tool should be examined at regular intervals for function and damage. Any questions regarding the correct operation of
tool and operator safety should consult the manufacturer, authorized local agent or distributor.
