PRINCIPLE OF OPERATION
PULL PRESSURE
PULL Cycle (FIGURE 1A)
When the Trigger Switch is pressed, a solenoid-
operated valve in the POWERIG®directs pressurized
hydraulic fluid through the PULL hose to the front side
of the Piston; fluid on the RETURN side flows back
to the tank (Figure 1A). The piston and nose assembly
collet move rearward, installing the fastener.
When the piston reaches the end of the PULL stroke,
it uncovers flats on the rear side of the Dump Valve.
These flats provide a passage for the hydraulic fluid
from the PULL side to the RETURN side of the piston,
“unloading” or “dumping” the pressurized fluid back to
the tank POWERIG (Figure 1A).
RETURN PRESSURE
RETURN Cycle (FIGURE 1B)
When the trigger is released, the solenoid is
de-energized and the valve directs pressurized fluid to
the rear side of the piston; fluid on the PULL side flows
back to the POWERIG tank (Figure 1B). The piston and
collet to move forward, and the tool and nose assembly
are pushed off the swaged (installed) fastener. When
the piston reaches the end of the RETURN stroke,
pressure builds up causing the POWERIG to shut off,
completing the cycle.

OPERATING INSTRUCTIONS
Review all CAUTIONs and WARNINGs prior to
installing fasteners. If the tool malfunctions, consult the
TROUBLESHOOTING section before attempting any repairs.
GENERAL
- Operators should receive training from qualified
personnel.
- Do not bend tool to free if stuck.
- Tool should only be used to install fasteners. Never
use as a jack/spreader or hammer.
- Reasonable care of tools by operators is an important
factor in maintaining efficiency and reducing
downtime.
TO INSTALL A HUCKBOLT® FASTENER:
1. Place a fastener in the workpiece and place the
collar over the fastener.
NOTE: If the collar has one tapered end, that end
must be out toward tool; not next to the sheet.
2. Hold the fastener in the hole and push the nose
assembly onto the fastener protruding through the
collar until the nose assembly anvil touches the
collar. Hold the tool at a right-angle (90 degrees) to
the work.
3. Move hands away from fastener and structure.
Keep hands away from the front of the tool during
operation; the tool anvil advances forward.
4. Press and hold the trigger until the collar is swaged
and the pintail breaks. Release the trigger; the tool
will perform its RETURN stroke.
The pressure is re-directed; the piston moves forward;
and the tool is pushed off the fastener and ready for the
next installation cycle.
CAUTIONS:
- To avoid structural and tooI damage, be
sure there is sufficient clearance for the
nose assembly at full stroke.
- Do not abuse the tool by dropping it,
using it as a hammer, or otherwise
causing unnecessary wear and tear.
- Do not connect tool’s hoses to each other
or use hoses as a handle for carrying.
R i ll CAUTION d WARNING i t
WARNINGS:
- Wear approved eye and hearing
protection.
- Ensure adequate clearance for operator’s
hands before installing fasteners.
- Be sure that pintail deflector is attached
to the tool and directed away from all
personnel.
- Do not pull on a pin without placing a
fastener/collar in a workpiece. Make sure
that the collar chamfer is out, toward the
tool. Pins eject with great velocity when
pintails break off or teeth/grooves strip,
which could cause serious injury.
1 Place a fastener in the workpiece and place the
CAUTION: Remove the excess gap from
between the sheets to ensure that enough
of the pintail emerges from the collar
for ALL chuck jaw teeth to engage with
the pintail. If ALL teeth do not engage
properly, chuck jaws will be stripped and/
or damaged.
NOTE: “Gap” is the space between
sheets. Gap is “excessive” if not enough
pintail sticks through the collar for the
nose assembly jaws to grip.

The operating efficiency of your tool is directly related
to performance of the entire system, including the
tool and nose assembly, hydraulic hoses, control
trigger assembly, and the POWERIG®Hydraulic Unit.
Therefore, an effective preventive maintenance program
includes scheduled inspections of the system to detect
and correct minor troubles.
NOTE: Where a part number (P/N) is given, Huck
sells that part.
SYSTEM INSPECTION
- Inspect the tool daily. Check hoses, fittings, and
couplings for leaks and damage. Clear air-lines of dirt
and water.
- Service the tool in a clean, well-lighted area. Take
special care to prevent contamination of pneumatic
