DESCRIPTION
Huck’s 2502 and A2502 series of Hydraulic Installation
Tools installs a wide range of Huck Blind Fasteners
and HUCKBOLT® Fasteners. These mini-tools are
lightweight and compact, which make them ideal for
installing fasteners in limited-clearance applications.
The 2502 tool series is designed to be powered by a
®
Huck POWERIG
Hydraulic Unit (or equivalent hydraulic
unit) with maximum operating pressures of:
• RETURN: 2400 psi (165.48 bar) and
• PULL: 5700 (see NOTE) psi (393.02 bar)
NOTE: The PULL pressure must be set at 8400
psi (579.18 bar) to install -12 diameter fasteners
in MG, GP, and LGP only.
Model 2502 has an electric switch and should be used
with POWERIG models 918, 918-5, 940, and 943-913.
Model A2502 has an air trigger and is suitable for use
with POWERIG models 942 and 970-3. NOTE: Model
970-3 may be used when lower PULL and RETURN
pressures are suffi cient.
Each tool is complete with 12 ft. hydraulic hoses and
couplings, an electric switch and cord (2502) or an
air trigger and tubing (A2502). 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
†
.
When the hydraulic hoses and trigger control are
connected to the POWERIG, an air or 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 end of the PULL stroke, the piston uncovers fl ats of
the unloading valve, and the pressure is unloaded by
allowing the fl uid to fl ow back to the POWERIG.
†
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 specifi c information on fastener
type and sizing.

PRINCIPLEOF OPERATION
When the hydraulic hoses and trigger control are
connected to the POWERIG® Hydraulic Unit, an air or
electric trigger controls the PULL and RETURN strokes
of 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 fl ats of
the unloading valve, and the pressure is unloaded by
allowing the fl uid to fl ow back to the POWERIG.
WARNING: 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 specifi cally NOT
RECOMMENDED and may be dangerous.
Set the PULL and RETURN pressures
as specifi ed in Specifi cations. 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.
