13.Never install a fastener in free air. Personal injury from fastener ejecting may
occur.
14.Where applicable, always clear spent pintail out of nose assembly before installing
the next fastener.
15.Check clearance between trigger and work piece to ensure there is no pinch point
when tool is activated. Remote triggers are available for hydraulic tooling if pinch
point is unavoidable.
16.Do not abuse tool by dropping or using it as a hammer. Never use hydraulic or air
lines as a handle or to bend or pry the tool. Reasonable care of installation tools
by operators is an important factor in maintaining tool efficiency, eliminating down-
time, and preventing an accident which may cause severe personal injury.
17.Never place hands between nose assembly and work piece. Keep hands clear
from front of tool.
18.Tools with ejector rods should never be cycled with out nose assembly installed.
19.When two piece lock bolts are being used always make sure the collar orientation
is correct. See fastener data sheet for correct positioning.

warnings should not be ignored. The operator should tell the employer and consult
a qualified health professional.
V. ACCESSORIES HAZARDS:
1. Disconnect tool from energy supply before changing inserted tool or accessory.
2. Use only sizes and types of accessories and consumables that are recommend-
ed. Do not use other types or sizes of accessories or consumables.
VI. WORKPLACE HAZARDS:
1. Be aware of slippery surfaces caused by use of the tool and of trip hazards caused
by the air line or hydraulic hose.
2. Proceed with caution while in unfamiliar surroundings; there could be hidden haz-
ards such as electricity or other utility lines.
3. The assembly power tool is not intended for use in potentially explosive environ-
ments.
4. Tool is not insulated against contact with electrical power.
5. Ensure there are no electrical cables, gas pipes, etc., which can cause a hazard if
damaged by use of the tool.
VII. NOISE HAZARDS:
1. Exposure to high noise levels can cause permanent, disabling hearing loss and
other problems such as tinnitus, therefore risk assessment and the implementation
of proper controls is essential.
2. Appropriate controls to reduce the risk may include actions such as damping mate-
rials to prevent workpiece from ‘ringing’.
3. Use hearing protection in accordance with employer’s instructions and as required
by occupational health and safety regulations.
4. Operate and maintain tool as recommended in the instruction handbook to prevent
an unnecessary increase in the noise level.
5. Select, maintain and replace the consumable / inserted tool as recommended to
prevent an unnecessary increase in noise.
6. If the power tool has a silencer, always ensure that it is in place and in good work-
ing order when the tool is being operated.

When the trigger is
depressed, a solenoid operated valve
in the POWERIG® directs pressurized
hydraulic fluid through the PULL hose
to the front side of the piston, and
allows fluid on the RETURN side to
flow back to the tank (Fig 1a). The
piston and nose assembly collet moves
rearward installing the fastener. When
the piston reaches the end of the PULL
stroke, it uncovers flats on the rear
end of the Dump Valve. These flats
are designed to provide a passage for
hydraulic fluid from the PULL side to
the RETURN side of the piston,
unloading or “dumping” the pressur‐
ized fluid back to the tank (Fig 1a).
When the trigger is released the sole‐
noid is de‐energized and the valve
directs pressurized fluid to the rear
side of the piston and allows fluid on the PULL side to flow back to the tank (Fig. 1b). This causes piston and collet to
move forward and pushes the nose assembly and tool off the swaged (installed) fastener. When the piston reaches the end
of the return stroke, pressure is built up, causing the POWERIG® to shut off, completing the cycle.

the appropriate POWERIG Instruction Manual.
TOOL MAINTENANCE
At regular intervals, depending on use, replace all O-
rings and back-up rings in the tool. Spare Parts Kits
should be kept on hand. Inspect cylinder bore, piston
and piston rod and unloading valve for scored sur-
faces, excessive wear or damage, and replace as
necessary.
NOSE ASSEMBLY MAINTENANCE
Daily cleaning of the nose assembly is recommended.
This can usually he accomplished by dipping nose
assembly in mineral spirits, or other suitable solvent,
to clean jaws and wash away metal chips and dirt. If
more thorough cleaning or maintenance is necessary,
disassemble the nose assembly. Use a sharp pointed
“pick” to remove imbedded particles from the pull
grooves of the jaws.
