Each time before using the Powerig Hydraulic Unit:
1.
Check the fluid level in the reservoir and add
hydraulic fluid as required.
2.
Inspect hoses for damage and wear. If hoses
show wear that has removed more than the sur-
face texture, they must be replaced.
3.
Check the entire system and repair any leaks.
4.
Check electrical cord and extension for abrasion
and replace as required.
OPERATING TOOLS
Plug the power cord into a grounded wall outlet. If an
extension cord is used, it should be UL type SO or
STO, 600 volt, 12/3 if 25 feet long and 10/3 if 50 feet
long.
Check pressures and adjust as necessary. See the
appropriate sections in this manual.
WARNINGS
MUST BE UNDERSTOOD BEFORE CHECKING
PRESSURES.
Connect a Huck hydraulic tool to the Powerig
Hydraulic Unit using a hose kit.
Be sure that:
1. Hose from PULL PRESSURE on the control
panel runs to the port stamped with a letter
P
on
the tool.
2. Hose from RETURN PRESSURE on the control
panel runs to the port stamped with letter
R
on
the tool.
Plug the control cable from the tool into the two-
prong socket on the Powerig Hydraulic Unit control
panel.
Depress the tool trigger switch and let the the
Powerig Hydraulic Unit operate for a few minutes to
circulate fluid and remove air from the system.
Attach a nose assembly to the installation equipment.
Fasteners may now be installed. Follow instructions
in the tool manual.

PREVENTIVE MAINTENANCE
An effective preventive maintenance program
includes scheduled inspections to detect and correct
minor troubles. Perform the following steps monthly
during normal use:
Inspect hydraulic and electrical fittings to be sure
they are secure.
Inspect hoses for signs of damage. Replace hoses if
abrasion is deeper than the surface texture.
Rotate hoses end-for-end to equalize wear and
fatigue.
Inspect during operation to detect any abnormal
heating, vibration or leakage.
Inspect hydraulic fluid. If contamination (particles,
water, sludge, etc.) is detected, clean the reservoir
and replace fluid.
Clean exterior surfaces.
Check supply voltage. Do not operate the POWERIG
Hydraulic Unit if the line voltage is more than 5 per-
cent above or below 220 Volts.
