Model 964 Powerig® Hydraulic Power Source is a portable, battery-operated power source designed to operate
all Huck hydraulic installation equipment, excluding Huck-Spin® tools. It operates using a 18 volt DC LI-ion 9Ah
battery, which is recharged on a charger using 115 volt AC, 50-60 Hz, one-phase electrical power. The motor is
rated at 18 volt DC, 144 W. The standard charger uses 110 – 120 volts AC, 2.1 amps AC, and supplies 18 volts
DC, 3.0 amps. Separately, a 220 – 240 volts AC charger is optionally available which uses 1.15 amps and supplies
18 volts DC, 3.0 amps. Hydraulic pressure is created by a two-stage, gear-piston pump driven by the motor.
Pressurized hydraulic fluid is directed by a four-way, three-position manual directional valve to either the PULL
or RETURN port of the installation equipment. When the tool trigger is connected to the supplied control cable,
the motor is turned on by pressing the trigger on the tool, which operates a 18 volt DC control circuit. When the
tool trigger is released the motor turns off. The motor may also be started by pressing the start button on the
handle of the unit behind the valve, but this button is overridden when the supplied control cable is plugged in.
The external pressure relief valve controls both the PULL and RETURN maximum pressure, and is adjustable by
the operator. The maximum pressure should generally be set to PULL pressure required by the Huck installation
equipment being used. The RETURN pressure will be the same as the PULL pressure, and will often be higher
than the recommended RETURN pressure required by the HUCK installation equipment. This is generally
acceptable given the low speeds and limited rate of use for tools using the Model 964B Powerig® Hydraulic
Power Source. If you have any questions or concerns regarding this, please contact your authorized Huck
distributor.
An internal relief valve is preset at the factory to protect the operator and the equipment. The internal relief is
not adjustable by the operator. Hydraulic fluid is stored in the bladder reservoir located inside the unit. Hydraulic
quick disconnect couplers are furnished for connecting hoses from installation equipment.
