Huck Model Series 2400, 2500 and 2600 (families) Sound Level
SEL = 75.8 dB (A)
peak value = 108.2 dB (C)
For an eight hour work day, installing 3000 typical Huck fasteners will result in an
equivalent noise level (Leq) of 66 dB (A).
To calculate equivalent noise level for other quantities of fasteners in an eight hour
period, use the formula:
Leq = SEL + 10 log (n/28,800)
where n = number of fasteners in eight hours
Huck Model Series 2400, 2500 and 2600 (families) Vibration Level
For an eight hour work day, installing 3000 typical Huck fasteners will result in an
equivalent weighted RMS vibration level (Aeq) of 12.50m/s2.
To calculate the equivalent vibration level for other quantities of fasteners in an eight
hour period, use the formula:
Equivalent Vibration Level, Aeq (m/s2) = (n/480) x 2.00
where n = number of fasteners in eight hours, and 2.00(m/s2) = Aeq for 60 seconds
Test data to support the above information is on file at Huck International, Inc., Kingston, NY, USA. Vibration
measurements are frequency weighted in accordance with ISO 8041 (1990).

SAFETY GLOSSARY
WARNINGS must be understood to avoid
severe personal injury.
Cautions show conditions that will damage
equipment and/or structure.
Notes are reminders of required procedures.
Italic type and underlining strengthens a
specific instruction.
WARNINGS
When operating Huck installation equipment
always wear approved eye protection.
Whenever within the working environment,
wear approved eye protection, with side
shields, to protect from anything that
breaks on the fastening system including:
Erupting fluid lines, flying fastener particles
or any other dirt/debris that could cause eye
injury. Where applicable, refer to ANSI
Z87.I - 1989.
Disconnect primary power source before
doing maintenance on Huck equipment.
• For electrically operated POWERIG®
Hydraulic Units, unplug the power cord
from the socket, If there is no plug, turn
off the power at the disconnect switch.
Follow lockout/tagout procedures in
force by your employer.
• For equipment powered by compressed
air, disconnect the air hose before doing
any maintenance.
• For hydraulic tools, or other hydraulic
equipment, disconnect the hydraulic
hoses from the hydraulic unit before
doing any maintenance.
If any equipment shows signs of damage or
leakage, DO NOT connect it to the primary
power supply (either electrical or
compressed air) - - and do not continue to
use equipment that develops erratic
symptoms. If equipment is damaged, or
there are other serious discrepancies,
affected equipment may rupture violently
- - parts may strike the operator, and/or
other personnel, and cause severe personal
injury. Ensure that ALL air and/or
hydraulic hose and/or electrical
plugs/connectors are correctly connected
before switching on power supply to
equipment. If incorrectly connected, the
tool may respond erratically and cause
severe personal injury. 7-1-97

DESCRIPTION
Model 2600 Hydraulic Installation Tool (HIT) with appropriate nose
assembly installs a wide range of Huck blind fasteners and HUCKBOLT®
Fasteners. This lightweight and compact mini tool is particularly adapted to
installing fasteners in limited clearance areas. Each tool is complete with
hydraulic hoses and couplings; electric switch and cord. The tool is
basically a cylinder and piston assembly. An unloading valve, designed to
relieve hydraulic pressure at end of the PULL stroke, is positioned by the
piston. End of piston rod is threaded and retaining nut and stop are
included for attaching nose assemblies.
Huck Hydraulic Installation Tools are designed to be powered by Huck
POWERIG® Hydraulic Units. The 2600 is designed to operate at
maximum of 5,700 psi (39,000 kPa) PULL and 2,800 psi (19,300 kPa)
RETURN pressures as supplied by Huck POWERIG Hydraulic Unit
Models 913, 918, 918-5, 940, 943, or equivalent.
A specific nose assembly is required for each fastener type and size. Nose
assemblies must be ordered separately - - see your Huck representative.

PRINCIPLE OF OPERATION
Refer to Figure 2
An electric trigger controls PULL and RETURN strokes of tool. Press
trigger to direct hydraulic pressure to PULL side of piston - - fastener
installation begins.
At end of PULL stroke, before trigger is released, piston uncovers flats of
unloading valve - - pressure is unloaded by allowing fluid to flow back to
POWERIG hydraulic unit. Release trigger at end of PULL stroke when
fastener is installed - - pressure is directed to RETURN side of piston and
moves piston forward. Nose assembly, with tool, is pushed off fastener.
WARNINGS
Operators of Huck Installation equipment must always wear approved
eye protection.
Only Huck POWERIG ® Hydraulic Units are recommended as the
power source for Huck tools. Units that deliver high pressure for both
PULL and RETURN, and are not equipped with relief valves, are
specifically not recommended. Severe personal injury or damage to
equipment may occur when using other units.
Proper PULL and RETURN pressures are important for
proper function of Installation Tools. Severe personal injury
or damage to equipment may occur without correct pressures.
Gauge Set-up, P/N T-10280, is available for checking these
pressures using instructions furnished with T-10280 and in
applicable POWERIG Hydraulic Unit instruction manuals.
See Checking and Adjusting Output Pressures.
CAUTION
Keep dirt and other foreign matter out of hydraulic systems
of the tools, hoses, couplers and POWERIG hydraulic Unit.
Do not let hose fittings and couplers contact a dirty floor or
unclean working surface. Foreign matter in hydraulic fluid may
cause hydraulic unit valves and tool valves to malfunction.

PREPARATION FOR USE
CAUTION: Do not let disconnected hoses and couplers contact a dirty floor.
Dirt/debris in hydraulic fluid causes valve failure in the equipment.
Checking and Adjusting Output Pressures
POWERIG® Hydraulic Unit pressures must be checked and adjusted at first time
start-up, after overhauling the unit and when troubleshooting.
WARNINGS: Correct PULL and RETURN pressures are required for operator’s
safety and for installation tool’s function. Gauge Set-up, T-10280, is available for
checking pressures - - see tool’s Table 1 - Specifications and INSTRUCTION
MANUAL, T-10280. Failure to verify pressures may result in severe injury.
Be sure to connect tools hydraulic hoses to POWERIG Hydraulic Unit before
connecting tools switch control cord to unit. IF NOT CONNECTED IN THIS
ORDER, severe personal injury may occur.
1. Use Huck POWERIG Hydraulic Unit, or equivalent, that has been
prepared per INSTRUCTION MANUAL. Check both PULL and
pressures and adjust to pressures given in Table 1 - Specifications of
this manual. See both hydraulic unit’s and T-10280’s manuals.
2. First, turn hydraulic unit to OFF, then, disconnect unit’s power supply.
3. Connect tool’s switch electrical cord to hydraulic unit.
4. Connect hydraulic unit to power supply. Turn unit to ON. Hold tool
trigger depressed for 30 seconds; depress trigger a few times to cycle
tool and to circulate hydraulic fluid. Observe action of tool and check
for leaks. Turn unit to OFF.
5. Select nose assembly from NOSE ASSEMBLY SELECTION
CHART for fastener to be installed. Disconnect tool’s control switch
electrical cord from hydraulic unit; disconnect hydraulic unit from power
supply. Attach nose assembly to tool as given by instructions on NOSE
ASSEMBLY DATA SHEET.
6. Reconnect hydraulic unit to power supply; reconnect tool’s switch
control cord to unit. Check operation of nose assembly - - see NOSE
ASSEMBLY DATA SHEET - - install fasteners in test plate of
correct thickness with proper size holes. Inspect installed fasteners.
If fasteners do not pass inspection, see TROUBLESHOOTING
to locate and correct tool malfunction.
