5.
Plug power cord into outlet. Use correct power source.
See page 2 for specifications. Keep power cords short
to avoid power losses. The console motor may
function at lower voltage, but motor speed and oil flow
will be reduced and motor may become damaged.
6.
Press “I” on the console switch to turn power on.
Pressing “I” activates the electrical circuit, but does
not turn the console motor on. The console motor is
activated by the pendant switch.
5.1 Pendant Operation
The pendant has two push button switches (See Figure
5). Press momentary push button (1) for “Advance.”
Release “Advance” and the torque wrench piston will
retract. Use the (2) “Motor off” push button if you need to
shut the unit off at any time.
NOTE:
The electric motor keeps running after the pendant
is released. Within 15 seconds of your last command
from the pendant, the motor will time-out and turn
off, preventing heat build-up and unnecessary wear.
5.2 Air Removal
When the wrench is first connected to the console, air will
be trapped in the components. To ensure smooth and safe
operation, remove air by cycling wrench several times
without load. Cycle until wrench advances and retracts
without hesitation.
Check oil level before operation.
NOTE:
Perform Air Removal and Pressure (Torque)
Adjustment:
1.
during initial operation or start-up.
2.
when connecting a different wrench to the console.
3.
when changing torque value (pressure adjustment
only).
5.3 Pressure (Torque) Adjustment
WARNING:
Make these adjustments BEFORE
putting torque wrench on nut or bolt head. The
console pressure setting may be above the pressure
needed to provide the required torque for your application.
Exceeding required torque will cause equipment damage
and may lead to serious personal injury.
REFER TO TORQUE WRENCH INSTRUCTIONS FOR
WRENCH OPERATING PROCEDURE.
1.
The console is supplied with a pressure gauge
installed. See torque wrench instructions for amount
of pressure required to produce desired torque. Note
that the maximum pressure varies for different
wrenches and accessories.
2.
Loosen locknut and back out relief valve to prevent
unintended pressure build-up. See Figure 1.
3.
Turn the console on.
4.
Press and hold the “Advance” push button and read
pressure gauge.
5.
While holding the “Advance” push button, turn relief
valve in (clockwise) to increase pressure or out
(counter-clockwise) to decrease maximum pressure.
Repeat until correct pressure is obtained.
NOTE:
When adjusting the pressure while the pump is
running the pressure must always start out at a
lower setting and then adjust the pressure
upwards.
6.
Tighten locknut on relief valve to maintain setting.
7.
Run the console several times to test the pressure
setting.
6.0 MAINTENANCE
6.1 Adding oil to the console
Check reservoir hydraulic oil level every 40 hours of
operation. Add hydraulic oil when necessary to bring oil
level up to 1 inch below the vent/fill opening.
6.2 Changing the oil
Completely drain the reservoir after every 100 hours of
operation. If console is operated in very dusty areas or at
high temperatures, drain and refill after 50 hours of
operation.
1.
Remove the vent/fill plug from reservoir.
2.
Tip the console until all old oil has drained out.
3.
Add new hydraulic oil through vent/fill opening until
the oil level is 1 inch below the vent/fill opening.
Reservoir capacity is 0.75 gallon (2.8 liters).
4.
Replace the fill plug.
5.
DISPOSE OF USED OIL PROPERLY
6.3 Cleaning the reservoir
The reservoir can be removed for cleaning, and should be
cleaned at least once a year.
1.
Remove vent/fill plug from reservoir. Tip the console
until all old oil has drained out.
2.
DISPOSE OF USED OIL PROPERLY.
3.
You will need to remove the blue shroud to get at the
screws that hold the console to the reservoir. Use a
hex wrench to remove the six screws securing shroud
to the reservoir.
4.
Disconnect wire(s) from solenoid valve. Mark wires
before disconnecting them from the 4-way valve.
