Installation
Location
The Petol Hydra-Tork Unit should be located in an area with adequate room to work the
downhole tools. The unit may be located indoors or outdoors upon solid level ground or a
finished shop floor. No special foundation is required.
Setup
Locate the hydraulic console in a convenient location and connect the hoses to the main
hydraulic cylinder and the lift cylinder.
Electrical Wiring
Connect electrical power to the console at the disconnect switch located in the access door of
the main electrical panel at the top of the console. The electrical supply should be made by a
qualified electrician in accordance with all applicable local codes and standards. If the unit
voltage must be changed to match the available supply voltage (e.g. after relocation), change
the motor wiring at the motor in the lower section of the console, change the primary leads
on the control transformer in the main electrical panel, and change the motor starter heater
elements in the main electrical panel. The spare parts list describes the heater elements
needed for all voltages.
Startup
Verify that the oil level is within the operating limits as shown on the console sight glass.
Use Chevron AW-ISO46 or equal (30 gallons). Turn on the disconnect switch to power up
the console. Start the hydraulic pump and immediately press any one of the cylinder control
buttons. If the cylinder does not move and if no hydraulic pressure is indicated (1)
immediately turn off the power; (2) lock out the power supply to the console; and (3) reverse
any two of the power supply leads to obtain the correct pump rotation.
If the main cylinder will only extend and not retract (1) turn off the power; (2) lock out the
power to the console; and (3) reverse the hoses attaching the console to the main cylinder.
If the lift cylinder operates opposite from the switch functions (1) turn off the power; (2) lock
out the power to the console; and (3) reverse the hoses attaching the console to the lift
cylinder.
Cycle the cylinder several times to clear the system of any entrapped air.
