• Use only sockets and accessories that correctly t the bolt or nut and function without tilting the tool off the
axis of the bolt.
• This tool is not insulated against electric shock.
• This equipment must not be operated or serviced unless the operator read the operating instructions and
fully understands the purpose, consequences and procedure of each step.
• When operating a larger tool above waist height, employ a secondary means of support for safety
purposes. A tool sling or chains may be used. Consult your safety department for further suggestions.
Depending on the working environment your local health and safety regulations may require
you wear protective gear (i.e. safety shoes, hard hat, gloves, coveralls, etc.). In case external
forces are exerted on the equipment, non-compliance with these regulations may result in
injury. EAR PROTECTION MUST BE WORN WHEN OPERATING THIS TOOL.
The Torque Reaction Arm must be
positioned against a positive stop.
Do not use the arm as a dead
handle. Take all precautions to
make certain the operator’s hand
cannot be pinched between the
arm and a solid object.
Do not use damaged,
frayed or deteriorated
hydraulic hoses
and ttings.

PLACING THE TOOL IN SERVICE
CONNECTING THE TOOL
1. Attach the twin line hose to the swivel inlets of the square drive torque wrench using the
spring–loaded quick connect ends.
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 with the swivels away from you, 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
for models SQ-1 SQ-3, and SQ-10 simply push the square drive into the housing until the drive
projects out the opposite side of the tool. For the model SQ-5, loosen and remove the square
drive retaining knob, 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 knob in the splined end of the
drive.
SETTING THE TORQUE
After determining the desired torque, use the calibration certicate provided with the tool to
determine the pressure necessary to achieve that torque. You may also refer to the chart
engraved on the shroud of the tool or the chart provided on pages 8-11 of this manual.
1. Connect the tool to the power supply and turn the pump on.
2. Depress the remote control button causing the pressure to be shown on the gauge.
3. Adjust the pressure by loosening the wing nut that locks the pressure adjustment thumb
screw. Rotate the thumbscrew clockwise to increase the pressure and counterclockwise to
decrease the pressure. When decreasing pressure, always lower the pressure below the
desired point and then bring the gauge back up to the desired pressure.
4. When the desired pressure is reached, retighten the wing nut and cycle the tool again to
conrm that the desired pressure setting has been obtained.

4
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.
SETTING THE REACTION ARM
An improperly
positioned reaction
arm may result in
operator injury
or damage to tooling.
Square Drive Hydraulic Wrench Reaction Points (Dwg.01)
Make sure the reaction arm is positioned correctly.
(Refer to Dwg. 01).
The reaction arm can be positioned numerous
places within a 360O circle. However, for the arm to
be correctly positioned, it must be set within a 90O
quadrant 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 on the other side when loosening.
(Dwg. 01)

5
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.
1. Insert the square drive into the mating socket. Then,
insert the safety pin through the socket, and seat the
included O-ring into the groove to capture the pin.
Place the socket onto the nut making sure the socket
is the proper size and that all mating parts are fully
seated.
2. Position the reaction arm or surface against an
adjacent nut, ange or solid system component. Make
certain that there is clearance for the hoses, swivels,
inlets and end plug. DO NOT allow the tool to react
against the hoses, swivels, inlets or end plug.
3. After turning the pump on and presetting the
pressure for the correct torque, depress the remote control 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.
5. When the nut is no longer turning and the pump gauge reaches the preset pressure,
release the remote control button. The piston rod will retract when the button is released,
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. Cycle the tool one additional time to ensure full torque.

MARINE MOLY GREASE
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 outdoors and dropped in loose dirt or sand.
Marine Moly Grease 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, drive segment and sleeves as instructed in the
maintenance section, and wash the components in a suitable cleaning solution in a well
ventilated area.
2. After drying the components, wipe a lm of Marine Moly Grease onto the wear surface of
both sleeves and the ends of the ratchet.
3. Spread a light lm of Marine Moly Grease onto the inner face and both sides of the drive
plate. Do not pack the teeth of the drive segment or ratchet with lubricant. It can prevent
the teeth from engaging properly.
4. Place a daub of Marine Moly Grease in the piston rod recess of the drive plate before
linking the piston rod to the drive plate at assembly.
CRITICAL LUBRICATION
It is imperative to lubricate the piston rod recess of the drive plate to piston rod contact area
every 80 hours of continuous duty cycling.
Lubricate as follows:
1. Remove shroud screws, shroud, and roll pin.
2. Pry the drive plate assembly forward from the piston rod to expose the recessed contact
area in the drive plate.
3. With a rag, wipe clean the area, and apply a sizeable amount of Marine Moly Grease.
4. Reassemble as instructed in the maintenance section.

SQ Series Uni-Swivel Assembly
1. Clamp the post (1) in a copper-covered or leather-covered vice by the base.
2. Slide the post O-rings (9) onto the post starting from the top to the base.
3. Lightly lubricate the post.
4. Using hand pressure, press the joint (2) onto the post until it makes contact with the base of the
post and until the top of the post is ush with the top of the joint.
5. For CSS uni-swivels: Install the retaining ring (5) into the groove on the top of the post by
spreading it open slightly and working it around the post. For CSL uni-swivels: Install the cap (6)
and secure with the cap screws (13).
6. Slide the joint O-rings (10) onto the arms of the joint from outside to inside.
7. Lightly lubricate the arms of the joint.
8. Using hand pressure, press the swivels (3 & 4) onto the joint. Note: One of the arms of the joint
has an ‘R’ engraved on the end denoting that it is the retract side. Install the retract swivel (4) onto
this arm.
9. Swing the arms together so they interlock and fasten them together with the swivel screw (11).
10. Install the large and small swivel O-rings (7 & 8) into their glands in the cylinder housing.
11. Install the uni-swivel assembly onto the cylinder housing with the swivel post screws (12).
