OPERATING THE WRENCH SYSTEM
By depressing the extend button on the remote control, the rear of the tool will be
pushed back until its reaction bar contacts its reaction member. Continue to hold
down the button as the socket turns pressure builds very rapidly to signify
that the hydraulic cylinder inside the tool is fully extended and will not turn
the nut any further. The rapid buildup of pressure should be to the point of
where the pressure was preset prior to applying the wrench.
IMPORTANT: This rapid buildup of pressure does not indicate that this
pressure (torque) is being applied to the fastener. It only
indicates that the cylinder is fully extended and can not turn the
socket further until the tool is retracted to pick up the next tooth
on the ratchet wheel.
Depressing the retract button on the remote control will retract the cylinder, the
tool will reset itself and the operator will hear a few audible “clicks” indicating he
can again push the remote control button and the socket will turn. Each time the
cylinder is extended and retracted, it is called a cycle. Successive cycles are
made until the tool “stalls” at the pre set pressure (torque).
NOTE: Always attempt one final cycle to insure the “stall” point has been
reached.
LOOSENING PROCEDURES
First, set the pump at the maximum pressure the tool can be used. Flip the tool
over so that it will loosen and apply the tool, assuring the reaction bar abuts
squarely off a solid reaction point. Press and hold the remote control button.
Pressure will build up as the socket begins to turn. Cycle the wrench until the
fastener is loose enough to turn by hand.
If the socket does not turn using the above procedure, it is an indication that you
will require the next larger size tool to loosen the fastener.
