See Figures 1 & 5. Model 940 POWERIG
®
Hydraulic Unit
is a portable, electrically operated power source designed
to operate all Huck hydraulic installation equipment exclud-
ing Huck-Spin
®
tools. Model 940 operates on 115 volt AC,
50-60 Hz, one-phase electrical power. The
power cord
is a
10/3 SJTO cord with a NEMA L5-30 plug. The
motor
on the
Powerig is rated at 115V, 50/60Hertz, 25A.
An
electrical enclosure
contains a motor contactor, trans-
former, relay and circuit breaker. Hydraulic pressure is
developed by a two-stage, gear-piston
pump
driven by a 1
1/8 horsepower universal electric
motor
. Pressurized fluid is
directed by a
four-way directional valve
to either the PULL
or RETURN port of the installation equipment. The four-way
directional valve is operated by a 24 volt AC control circuit.
The
high pressure relief valve
controls PULL pressure
(maximum pressure of the unit) and is adjustable by the
operator. An internal relief valve is preset at the factory to
protect the Operator and equipment. The internal relief is
not adjustable by the operator. A
pressure switch
controls
RETURN pressure and turns off the POWERIG Hydraulic
Unil at the end of an installation cycle. Pressures are adjust-
able to match Huck equipment being used. See applicable
tool instruction manual for pressure settings for other Huck
installation equipment.
Hydraulic fluid is stored in the
reservoir
which also serves
as the base. Remove the
filler cap/dipstick
to check fluid
level and to add fluid.
Hydraulic quick disconnect cou-
plers
are furnished for connecting hoses from installation
equipment.
