Pull Pressure (Pull Cycle)
Fig. 1(a)

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
unloading 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
pressurized fluid back to the tank (Fig 1a).
When the trigger is released the solenoid 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 power rig to shut off,
completing the cycle.

ceeding with maintenance and repair. Use proper hand
tools in a clean and well-lighted area. Only standard
hand tools are required in most cases. Where a special
tool is required, the description and part number are
given.
•

While clamping tool or parts in a vise, and when parts
require force, use suitable soft materials to cushion
impact. For example, using a half-inch brass drift,
wood block and vise with soft jaws greatly reduces possibility of damaging tool. Remove components in a
straight line without bending, cocking or undue force.
Reassemble tool with the same care.

GOOD SERVICE PRACTICES

Tool Maintenance
Whenever disassembled and also at regular intervals
(depending on severity and length of use) replace all
seals, wipers and back-up rings in tool. Service Kits,
hoses and extra parts should be kept in stock. Inspect
cylinder bore, pistons and piston rods for scored surfaces and excessive wear or damage. Replace as necessary.

(continued)

Sealants, Lubricants, Hydraulic Fluid & Service Kits
• Rub SLIC-TITE TEFLON thread compound, or
equivalent, on pipe threads to prevent leaks and for
ease of assembly. CAUTION: Do not use TEFLON
tape on pipe threads. Particles of shredded tape
cause hydraulic unit valve failure. (SLIC-TITE in
stick form, 503237).
•

Smear LUBRIPLATE 130AA, or equivalent, on Orings and mating surfaces to prevent damaging Orings on rough or sharp surfaces. Also, increases
ease of assembly. (LUBRIPLATE in a tube, 502723).

•

Each Service Kit contains perishable parts for your
specific tool. As foreseeable use may indicate, keep
extra kits (O-rings, Back-up Rings, other standard
items) and tool parts in stock. When stock is depleted, you can get kit items from any regular retailer of
these items. See kit parts list for: O-ring size
(AS568- number); material; durometer. For kit parts
lists and related information, see General Notes.

Nose Assembly Maintenance
Clean nose assembly often. Dip in mineral spirits, or
similar solvent, to clean jaws and wash away metal
chips and debris. At regular intervals, as experience
shows, disassemble nose and use a sharp "pick" to
remove imbedded particles from grooves of jaws.

DISASSEMBLY - ALL MODELS
For component identification and Parts Lists refer
to Figures 8-12.
NOTE:
The following procedure is for complete disassembly of
tool. Disassemble only components necessary to
replace damaged O-rings, Quad-Rings, Back-up Rings,
and worn or damaged components. Always use soft jaw
vice to avoid damage to tool.

PREVENTIVE MAINTENANCE
System Inspection
Operating efficiency of the tool is directly related to the
performance of the complete system, including the tool
with nose assembly, hydraulic hoses, trigger switch and
control cord, and POWERIG Hydraulic Unit. Therefore,
an effective preventive maintenance program includes
scheduled inspections of the system to detect and correct minor troubles.

• Inspect tool and nose assembly for external damage.

WARNING: Be sure to disconnect tool's electric control trigger system from Hydraulic Unit
before disconnecting tool's hoses from unit.
Before any maintenance is done, DISCONNECT IN THIS ORDER (RECONNECT IN THE
OPPOSITE ORDER) to avoid possible severe
personal injury.

1. Disconnect electrical or air connector from Powerig.
Uncouple tool hydraulic hoses.
