2624 & 2630 series Hydraulic Installation Tools (HK1052)
Upon pressing trigger, a solenoid-operated
valve in the Powerig
®
hydraulic power
source
directs pressurized fluid through the
PULL hose to the front side of the piston;
fluid on the RETURN side flows back to the
tank (Fig 1a). The piston and nose assembly
collet move rearward, installing the fastener.
When the piston reaches the end of the PULL
stroke, it uncovers flats on the rear end of
the dump valve, providing a passage for fluid
from the PULL side to the RETURN side of
the piston, “dumping” the pressurized fluid
back to the tank (Fig 1a).
Upon releasing trigger, the solenoid
is de-energized and the valve directs
pressurized fluid to the rear of the piston;
fluid on the PULL side flows back to the tank
(Fig. 1b). The piston and collet move forward,
pushing the nose assembly and tool off the
installed fastener. When the piston reaches
the end of the RETURN stroke, pressure
builds, causing the Powerig to shut off,
completing the cycle.
Principle of Operation
POWER SOURCE CONNECTIONS
Use a Huck Powerig
® h
ydraulic power source, or
equivalent, that has been suitably prepared for operation.
1.
Turn OFF the Powerig and disconnect its power supply.
2.
Coat the tool’s hose-fitting threads with Loctite
®
243
™
or equivalent, and then connect the hoses to the
Powerig.
3.
Connect the tool’s control switch cord to the Powerig.
4.
Connect the Powerig to the power supply and turn it
ON. Press and hold the tool trigger for 30 seconds; then
press trigger a few times to cycle the tool and circulate
the hydraulic fluid. Observe the action of the tool and
check for leaks. Turn OFF the Powerig.
5.
Disconnect tool’s control switch cord from the Powerig;
disconnect the Powerig from the power supply. Select
a nose assembly for the fastener to be installed and
attach it to the tool.
6.
Reconnect the Powerig to the power supply and the
tool’s switch control cord to the Powerig.
7.
Check the operation of nose assembly; install fasteners
in a test plate of correct thickness with proper size
holes. Inspect installed fasteners.
NOTE: If fasteners do not pass inspection, see
Troubleshooting
to investigate possible causes.
Preparation for Use
WARNINGS:
Read entire manual before using tool.
A 30-minute training session with qualified personnel is recommended before using Huck equipment.
When operating Huck equipment, always wear approved eye and hearing protection.
Huck Powerig® hydraulic power sources should be used to power Huck tools. Hydraulic power units that
deliver high PULL and RETURN pressures, but which are
not equipped with relief valves,
are specifically
NOT RECOMMENDED and may be dangerous.
Connect tool hydraulic hoses to Powerig
before
connecting tool switch-control cord to Powerig. If not
connected in this order and
disconnected in the reverse order
, severe personal injury may occur.
Set
PULL and RETURN pressures as specified in Specifications
. Failure to properly set these pressures
may result in serious personal injury.
Huck Pressure Gauge T-124833CE is available and should be used as indicated in its instruction manual.
Ensure there is adequate clearance for the operator’s hands before proceeding.
CAUTION:
Keep disconnected hoses and couplers and hydraulic fluid free of foreign matter.
Contaminated fluid can cause valve failures. Apply Parker Threadmate, Loctite 567, or Slic-tite stick to
male pipe threads per manufacturer’s instructions.
