SETTING THE TORQUE

After determining the desired torque, use the torque conversion chart on the Shroud or the torque conversion

charts on page 5 to determine the pressure that is necessary to achieve that torque.

1. Connect the tool to the power supply and turn the pump on.

2. Depress the advance remote control button causing the pressure to be shown on the gauge.

3. Adjust the pressure by first loosening the nut that locks the pressure adjustment handle and then rotate the

handle clockwise to increase the pressure and counter clockwise to decrease the pressure.

When decreasing pressure, always lower the pressure below the desired point and then bring the pressure

gauge back up to the desired pressure.

4.When the desired pressure is reached, retighten the lock nut and cycle the tool again to confirm that the

desired pressure setting has been obtained.

SETTING THE REACTION ARM

The function of a reaction device is to hold the tool in position against the forces generated to tighten or loosen

bolts or nuts. Hydraulic wrenches generate tremendous force.

Make sure the Reaction Arm is positioned correctly. (Refer to Drawing 01).

The Reaction Arm can be positioned in numerous places within a 360

correctly positioned, it must be set within a 90

between the protruding Square Drive and the bottom of the Housing away from the Swivel Inlets. It will always

be toward the lower half of the Housing and on one side of the Housing when tightening and the other side

when loosening.

OPERATING THE WRENCH

The position of the Square Drive relative to the Shroud determines whether the action will tighten or loosen the

nut. (Refer to Dwg. 02 for application examples).

The power stroke of the Piston Assembly will always turn the Square Drive toward the Shroud.

WRENCH POSITIONS

1. Place the Square Drive in the socket, insert the socket retainer ring and pin, and place the socket on the nut.

Make certain the Square Drive and socket are the correct size for the nut and that the socket fully engages the

nut

2. Position the reaction arm against an adjacent nut, flange or solid system component. Make certain that there

is clearance for the hoses and uni-swivel coupling. DO NOT allow the tool to react against the hoses, or uni-

swivel coupling. When reacting directly off the tool body ie., with reaction arm removed DO NOT react off the

exposed End Plug Spigot.

3. After having turned the Pump on and presetting the pressure for the correct torque, depress the remote

control advance button to advance the Piston Assembly

4. When the wrench is started, the reaction surface of the wrench or Reaction Arm will move against the contact

point and the nut will begin to turn. Once the piston reaches the end of its stroke depress the remote control

return button to retract the piston.

5. Continue this cycling operation of advance

and retract until the nut is no longer turning and the Pump Gauge reaches the preset pressure. The piston rod

will retract when the retract button is pressed and under normal conditions, an audible "click" will be heard as

the tool resets itself.

6. Continue to cycle the tool until it "stalls" and the preset psi/torque has been attained.

7. Once the nut stops rotating, cycle the tool one last time to achieve total torque.
