FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY

USING THE TOOL

•Keep hands, loose clothing and long hair away from the reaction arm and working area during

operation. Do not attempt to support the tool with your hands during operation.

•This tool will exert a strong reaction force. Use proper mechanical support and correct reaction arm

positioning to control these forces. Do not position the reaction arm so that it tilts the tool off the axis

of the bolt and never use the swivel inlets as a reaction stop.

•Avoid sharp bends and kinks that will cause severe back-up pressure in hoses and lead to premature

hose failure.

•Use accessories recommended by Hi-Force.

•Use only impact sockets and accessories. Do not use hand (chrome) sockets or accessories.

•Use only sockets and accesssories that correctly fit the bolt or nut and function without tilting the

tool off the axis of the bolt.

•This tool is not designed for working in explosive atmospheres

•This tool is not insulated against electric shock. When using this tool with a pump having an electrical

power source or circuits, follow the pump instructions for proper grounding.

hose. Do not use damaged, frayed or

deteriorated hydraulic hoses and fittings.

Keep body stance balanced and firm. Do not

overreach when operating this tool.

PLACING THE TOOL IN SERVICE

CONNECTING THE TOOL

1. Attach the twin line hose to the uni-swivel coupling of the Square Drive Torque Wrench using the spring–

loaded quick connect ends. Make certain that they are fully engaged.

2. Connect the opposite ends of the hose to the Pump in the same manner.

ADJUSTMENTS

SETTING THE SQUARE DRIVE FOR

ROTATION

The position of the Square Drive when looking toward the Shroud will determine if the tool is set to tighten or

loosen the nut. When the Square Drive extends to the left when looking at the Shroud from the front, the tool is

set to loosen the nut. When the Square Drive extends to the right, the tool is set to tighten the nut. To change

the direction of rotation press the push button release on the drive retaining plate and pull the Square Drive out

of the Housing. Insert the Square Drive into the opposite side of the Housing and secure it by installing the push

button release retaining plate into the end of the drive.

TDS1288

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.

WARNING

An improperly positioned reaction arm may

result in operator injury or damaged tooling.

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

The Reaction Arm can be positioned in numerous places within a 360O circle. However, for the Arm to be

correctly positioned, it must be set within a 90Oquadrant of that circle. That quadrant is the area located

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.

PLACING THE TOOL IN SERVICE

LUBRICATION

Marine Grade Moly Lube

Lubrication frequency is dependent on factors known only to the user. The amount of contaminants in the work

area is one factor. Tools used in a clean room environment will obviously require less service than a tool used

out-doors and dropped in loose dirt or sand. Marine Grade Moly Lube is formulated not to wash out of the tool in

areas where lubrication is critical.

Whenever lubrication is required, lubricate as follows:

1. Remove the Drive Plate, Ratchet, Segment Pawl and Drive Sleeves and wash the components in a suitable

cleaning solution in a well–ventilated area.

2. After drying the components, wipe a film of Moly Lube (Marine Grade) onto the wear surface of both Drive

Sleeves and the ends of the Ratchet.

3. Spread a light film of Moly Lube (Marine Grade) onto the inner face and both sides of the Drive Plate.

Do not pack the teeth of the Segment Pawl or Ratchet with lube. It can prevent the teeth from engaging

properly.
