7
Preparation for Use
1. Rub Slic-Tite® TEFLON® thread compound, or
equivalent, on pipe threads to prevent leaks and for ease
of assembly.
2. Use Huck Powerig® Hydraulic Power Source®, or
equivalent, that has been prepared for operation per
instruction manual. Check both PULL and RETURN
pressures, and ensure they are adjusted to pressures
given in SPECIFICATIONS of this manual. See both
hydraulic unit instruction manual and T-124883CE
instruction manual before and during checking
procedure. Visually inspect for leaks and to verify that
End Cap is installed correctly.
3. First, turn hydraulic unit to OFF; then disconnect power
supply from hydraulic unit. Disconnect trigger control
system from hydraulic unit.
4. Connect tool hoses to hydraulic unit. If required, adjust
position of trigger assembly on return pressure hose.
Connect trigger control system to hydraulic unit.
5. Connect hydraulic unit to power supply (air or electric).
Turn hydraulic 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.
6. Select the appropriate nose assembly for the fastener to
be installed. Disconnect hydraulic unit from power
supply. Disconnect tool’s trigger control system from
hydraulic unit. Attach nose assembly to tool.
7. Reconnect tool’s trigger control system to hydraulic unit;
reconnect unit to power supply. Check operation of nose
assembly. Install fasteners in test plate of correct
thickness with proper size holes. Inspect installed
fasteners. If fasteners do not pass inspection, see
TROUBLESHOOTING section of this manual to locate
and correct malfunction.
8. Operator should receive training on proper use of Huck
equipment from qualified personnel.proceed logically,
eliminating each possible cause until the defective part is
located. Where possible, substitute known good parts
for suspected defective parts. Use Trouble Shooting
Chart as an aid for locating and correcting trouble.
CAUTIONS:
Do not let disconnected hoses and couplers
contact a dirty floor. Keep harmful material out
of hydraulic fluid. Dirt in hydraulic fluid causes
valve failure in tool and in Powerig Hydraulic
Unit.
Do not use TEFLON
®
tape on pipe threads. Pipe
threads may cause tape to shred resulting in
tool malfunction. (Slic-Tite is available in stick
form as Huck P/N 503237.)
WARNINGS:
Correct PULL and RETURN pressures are
required for operator safety and for
installation tool function. Gauge p/n
T-124883CE is available for checking pressures.
See Tool specifications and gauge instruction
manual. Failure to verify pressures may result
in severe personal injury.
Be sure to connect Tool’s hydraulic hoses to
Powerig® Hydraulic Power Source before
connecting Tool’s switch control cord to unit. If
not connected in this order, severe personal
Injury may occur.
