Specifications
Huck’s 2580 series of Hydraulic Installation Tools—when
tted with an appropriate nose assembly—installs a
wide range of Huck Blind Fasteners and HUCKBOLT®
Fasteners. These lightweight and compact mini-tools
are ideal for installing fasteners in limited-clearance
applications.
Each tool is complete with hydraulic hoses and
couplings, an electric switch and cord. The tool is
basically a cylinder and piston assembly. An unloading
valve, designed to relieve the hydraulic pressure at the
end of the PULL stroke, is situated near the piston. The
end of the piston rod is threaded, and a retaining nut
and stop are included for attaching nose assemblies†.
The 2502 series of tools is designed to be powered by
a Huck Powerig® Hydraulic Unit (models 913, 918, 918-
5, 940, and 956 or an equivalent hydraulic unit) with
maximum operating pressures of:
• PULL: 5700 psi (393.02 bar)
• RETURN: 3200 psi (220.64 bar) and
†Nose assemblies must be ordered separately. A distinct
nose assembly is required for each fastener, based on
type and size. Contact your Huck representative for
the appropriate Nose Assembly Selection Chart and the
various Huck Fastener Selection Chart for more specic
information on fastener type and sizing.

Principle of Operation
When the hydraulic hoses and trigger control are
connected to the Powerig® Hydraulic Unit, an electric
trigger controls the PULL and RETURN strokes of the tool.
The trigger is pressed and hydraulic pressure is directed to
the PULL side of the piston. Fastener installation begins.
When fastener installation is completed, the trigger is
released. Hydraulic pressure is directed to the RETURN
side of the piston, moving it forward. The tool and nose
assembly are pushed off the installed fastener. At the
end of the PULL stroke, the piston uncovers ats of the
unloading valve, and the pressure is unloaded by allowing
the uid to ow back to the Powerig.
WARNINGS:
Read entire manual before using tool.
A 30-minute training session with qualied personnel is recommended before using Huck equipment
When operating Huck equipment, always wear approved eye and hearing protection.
Be sure there is adequate clearance for the operator’s hands before proceeding.
Connect the tool’s hydraulic hoses to the Powerig®Hydraulic Unit before connecting the tool’s trigger
control system to it. If not connected in this order, severe personal injury may occur.
Huck recommends that a Huck Powerig be used to power Huck tools. (Only use the Powerig as indicated
in its instruction manual.) Hydraulic power units that deliver high PULL and RETURN pressures—but
which are NOT equipped with RELIEF VALVES—are specically NOT RECOMMENDED and may be
dangerous.
Set the PULL and RETURN pressures as specied in specIfIcatIons. Failure to properly set these pressures
could result in serious personal injury.
Use Huck Pressure Gauge, p/n T-124883CE, as indicated in its instruction manual. Improper pressure
settings may result in severe personal injury.
Preparation for Use
CHECKING & ADJUSTING OUTPUT PRESSURES
Check and adjust hydraulic pressures at rst time start-up,
after overhauling the unit, and when troubleshooting.
Use a Huck Powerig® Hydraulic Unit that has been suitably
prepared for operation.
NOTE: Review all WARNINGS on this page.

The operating efciency of Huck equipment is directly
related to performance of the entire system, including tool,
nose assembly, hoses, trigger assembly, and Powerig®.
An effective preventive maintenance program includes
scheduled inspections of the system to detect and correct
minor troubles.
SYSTEM INSPECTION/PREVENTIVE MAINTENANCE
- Inspect tool and nose assembly daily for damage
and wear. Before each use, verify that the tool, hoses,
ttings, couplings, and trigger connections are secure,
undamaged, and free of leaks; replace as necessary. Clear
air-lines of dirt and water.
- Inspect tool, hoses, and Powerig during operation to
detect abnormal heating, leaks, or vibration.
- Service the tool in a clean, well-lighted area. Take
special care to prevent contamination of pneumatic and
hydraulic systems.
- Carefully handle all parts and components. Before
re-assembly, examine them for damage and wear;
replace when necessary. Replace O-rings and Back-up
rings whenever the tool is disassembled.
- Have available all necessary hand tools (standard and
special); a half-inch brass drift and wood block; an arbor
press; and a soft-jaw vise. Unsuitable hand tools could
damage tool. See KIts & accessorIes.
- Follow the disassembly and assembly procedures in
this manual. If Huck-recommended procedures are not
followed, tool damage could result.
- Disassemble and assemble tool components in a straight
line. Do NOT bend, twist, or apply undue force. Always
apply continuous steady pressure to disassemble a
component. An arbor press provides steady pressure to
press a component into or out of an assembly.
- Never force a misaligned component. Reverse the
procedure, correct the misalignment, and start over.
FLUID MAINTENANCE
See specIfIcatIons for uid type. For uid maintenance,
refer to NAS 1638 class 9, ISO CODE 18/15, or SAE level
6. Dispose of uid in accordance with local environmental
regulations. Recycle steel, aluminum, and plastic parts in
accordance with local lawful and safe practices.
STANDARD SEALANTS, LUBRICANTS
- Apply Parker Threadmate®, Loctite®567, or Slic-Tite®to
male pipe threads per manufacturer’s instructions (to ease
assembly and to prevent leaks).
- Smear LUBRIPLATE®130-AA or SUPER-O-LUBE®on
rings and mating parts to ease assembly and to prevent
nicking/pinching rings on rough/tight spots.
POWERIG MAINTENANCE
Maintenance instructions and repair procedures are in the
appropriate Powerig Instruction Manual.
TOOL MAINTENANCE
Whenever disassembled, and at regular intervals,
depending on use, replace all O-rings and Back-up rings.
Tool-specic Spare Parts Service Kits should be kept
on hand. Inspect cylinder bore, piston, piston rod, and
unloading valve for scored surfaces, excessive wear, and
damage; replace as necessary.
NOSE ASSEMBLY MAINTENANCE
Clean nose assemblies in mineral spirits to clear jaws and
rinse metal chips and dirt. For a more thorough cleaning,
disassemble the nose assembly. Use a pointed “pick” to
remove embedded particles from the pull grooves of the
jaws. Clean all parts of any assembly with UNITIZEDTM Jaws
in mineral spirits or isopropyl alcohol only; do not let jaws
come in contact with other solvents. Do not let jaws soak;
dry them immediately after cleaning. Huck recommends
drying other parts before re-assembling.
Maintenance
CAUTIONS:
Consult the Material Safety Data Sheet
(MSDS) before servicing tool.
Keep foreign matter out of the hydraulic
system. Keep separated parts away from
