personal injury.
12. Never remove any safety guards or pintail deflectors.
13. Never install a fastener in free air. Personal injury from fas-
tener 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 trig-
gers 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
downtime, 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

The nose assembly is placed over the end of the fastener
until the tool's puller bottoms on the fastener. When the
trigger is pressed, a solenoid‐operated valve in the powerig
directs pressurized hydraulic fluid through the PULL hose to
the rear side of the piston and allows fluid on the RETURN
side to flow back to the tank. The piston moves forward to
start the swaging process.
After the fastener is fully swaged, the trigger must be
released, at which point the solenoid is de‐energized and the
valve directs pressurized hydraulic fluid to the front side of
the piston and allows fluid on the PULL side to flow back to
the tank. This causes the piston to move back while pushing
the anvil off of the swaged collar, releasing the tool from the
fastener.

O
OPERATING PERATING I INSTRUCTIONS NSTRUCTIONS
For safe operation. Please read completely
WARNING: To avoid severe personal injury,
wear approved eye and ear protection. Ensure
adequate clearance for Operator’s hands
before proceeding with fastener installation.
WARNING: Do not pull on a pin without plac-
ing fastener/collar in a workpiece. This can
cause pin to eject with great velocity and
force if pintail breaks off or teeth or grooves
strip. This may cause severe personal injury.
CAUTION: Remove excess gap from between
the sheets. This permits enough pintail to
emerge from collar for ALL puller teeth to
engage with pintail. If ALL teeth do not engage
properly, jaws will be damaged.
WARNING: To avoid pinch point, never
place hand between nose assembly and
work piece.
WARNING: Only use compatible equip-
ment with this tool.

dance with local lawful and safe practices.
PREVENTIVE MAINTENANCE
NOTE: For supplementary information refer to
T
TROUBLESHOOTING ROUBLESHOOTING, Parts Lists, and D DISASSEMBLY ISASSEMBLY
AND
AND A ASSEMBLY SSEMBLY procedures in this manual.
SYSTEM INSPECTION
Operating efficiency of the installation tool is directly
related to performance of the complete system,
including the tool with nose assembly, hydraulic
hoses, trigger and control cord, and POWERIG.
Therefore, an effective preventive maintenance pro-
gram includes scheduled inspections of the system to
detect and correct minor troubles.
1. Inspect tool and nose for external damage.
2. Verify that hydraulic hose fittings and couplings
and electrical connections are secure.
3. Inspect hydraulic hose for signs of damage or
aging. Replace hoses if damaged.
.4. Inspect tool, hose, and POWERIG during operation
to detect abnormal heating, leaks, or vibration.
POWERIG MAINTENANCE
Maintenance instructions and repair procedures are in
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 Kit
SFBTT15KIT should be kept on hand. Inspect cylin-
der bore, piston and piston rod and unloading valve
for scored surfaces, 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.
CAUTIONS:
- Consult MSDS before servicing tool.
- Keep dirt and other material out of
hydraulic system.
- Separated parts most be kept away
from dirty work surfaces.
- Dirt/debris in hydraulic fluid causes
Dump Valve failure in Tool and in POW-
ERIG® Hydraulic Unit’s valves.
- Always check tool assembly drawing
for the proper direction of the flats on
the Dump Valve.
CAUTION: Always replace seals, wipers,
and back-up rings when tool is disassem-
bled for any reason.
CAUTION: Do not use TEFLON®tape on
pipe threads. Pipe threads may cause tape
to shred resulting in tool malfunction.

GENERAL PRECAUTIONS
During disassembly and assembly, take the following
precautions to avoid damaging tool or components:
(a) Always work on a clean surface.
(b) Use relatively soft materials, such as brass,
aluminum or wood, to protect tool when applying
pressure.
(c) Apply a continuous strong pressure, rather than
sharp blows, to disassemble or assemble a com-
ponent. An arbor press provides steady pressure
to press a component in or out.
(d) Never continue to force a component if it “hangs
up” due to misalignment. Reverse the procedure
to correct misalignment and start over.
(e) Smear LubriplateTM 13OAA or equivalent on O-
rings and mating surfaces to aid assembly and
prevent damage to O-rings. (A handy tube of
Lubriplate 13OAA is available from Huck as part
number 502723).
(f) Coat pipe plug threads, hose fitting threads, and
quick connect fittings with Threadmate™, which
is available from Huck in a 4oz. tube as part
number 508517. DO NOT use Teflon tape on
hose fitting threads.
DISASSEMBLY AND ASSEMBLY TOOLS
Standard hand tools such as wrenches, drifts, copper
or lead hammers, screwdrivers, socket screw hexa-
gon keys, long forceps (tweezers), etc. which can be
purchased at most local supply firms are required. If
possible, an arbor press and vise with soft jaws
should be available.
SPARE PARTS AND SPARE PARTS KITS
The quantity of spare parts that should be kept on
hand varies with the application and number of tools
in service. However, spare parts kits containing per-
ishable parts such as O-rings, back-up rings, etc.,
should be kept on hand at all times.
POWERIG MAINTENANCE
Maintenance instructions and repair procedures are in
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 Kit
SFBTT15KIT should be kept on hand. Inspect cylin-
der bore, piston and end cap for scored surfaces,
excessive wear or damage, and replace as neces-
sary.
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. Apply anti-seize lubricant, part
number 505565, to outside of puller and inside of
anvil.
