Specifications
CHECKING PRESSURES
WARNINGS above must be understood.
Check PULL and
RETURN pressures before use, before troubleshooting, and
after overhauling. See pressures given in the specific tool
instruction manual. For checking pressures, use T-124833CE
Pressure Gauge and its instruction manual.
ADJUSTING PRESSURES
NOTE: Using gauge T-124833CE, set pressures according to
the specific installation equipment manual.
ADJUSTING PULL PRESSURE
NOTE: PULL pressure is the maximum Powerig
®
pressure.
Do not exceed the pressure rating of the installation
equipment. See the installation equipment manual for
pressure rating.
1. Loosen the jam nut of the high pressure relief valve.
2. Turn the adjusting screw clockwise to increase PULL
pressure OR counterclockwise to decrease PULL pressure.
3. Tighten the jam nut after PULL pressure has been
adjusted.
4. Check PULL pressure. Follow instructions in the
appropriate section of this manual.
ADJUSTING RETURN PRESSURE
1. Loosen the jam nut on pressure switch.
2. Turn the adjusting screw clockwise to increase RETURN
pressure OR counterclockwise to decrease RETURN
pressure.
3. Tighten the jam nut on pressure switch after return
pressure has been adjusted.
4. Check RETURN pressure. Follow instructions in the
appropriate section of this manual.
Checking and Adjusting Pressures
WARNINGS:
Maximum PULL pressure is 8400 psi. Refer to
specific tool instruction manual for PULL and
RETURN pressures. Severe personal injury may
occur if excessive pressures cause violent failure
of equipment. Higher than normal pressures will
also cause premature wear of equipment.
If recommended maximum pressure is exceeded,
violent failure of fastening system may occur.
This may cause severe personal injury.
Operation
Before each use:
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 surface 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.
Be sure that the hose from
PULL PRESSURE
on the
control panel runs to the port stamped with a letter
‘P’
on the tool, and the 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 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.
Operating Tools:
Plug the power cord into a grounded wall outlet.
Check pressures and adjust as necessary. See the appropriate
sections in this manual.
WARNINGS must be understood
before checking pressures.
Connect hydraulic hoses from a
HUCK hydraulic tool to the Powerig.
