INTRODUCTION
The Hyspan Pistol Grip hydraulic torque wrench is a hand held, non-impacting hydraulic driven,
reversible power tool designed to quickly and accurately apply torque to tighten and remove threaded
fasteners. The unit is ideal for all types of maintenance work, above and below ground, offshore and sub-
sea. It may be powered from the customers own hydraulic supply or via a Christie supplied power pack.
The direction is changed using the direction selector.
The unit is operated from a soft start trigger.
The Hyspan multiplier must always be operated with the following:-
Single acting hydraulic power pack capable of 2,000 psi (140 bar)
Power pack flow rate of 15-46 litres/minute (0.53-1.62 cfm)
Hydraulic mineral oil. (none synthetic, Grade 32 or equivalent.
Hydraulic hoses. Working pressure 4790 psi (330 bar), 3/8" (10mm) bore.
Impact quality sockets or adaptors
TRAINING REQUIREMENTS
Training on the correct use of the equipment is available. Please contact W. Christie (Industrial) Ltd for
more information.

GENERAL SAFETY
The improper use of hydraulic equipment is unsafe and may result in personal injury. It is important that
operators have read, understood and comply with all instructions in this user guide.
If more than one individual is involved in the operation of the equipment then all must read the operators
handbook. Good communication must be established to prevent accidents or misunderstandings.
Operators must be equipped with the following personal protective equipment (PPE):-
Eye Protection (Safety Glasses / Goggles)
Safety Footwear (Steel Toe Cap Boots)
Heavy Gloves
Impact quality sockets must be secured to the tool square drive by means of a pin and ring combination.
Care must be taken not to exceed the maximum working pressure of the equipment. See the torque chart
provided. Failure or breakup of components may result in personal injury.
Take care not to stand on, run over or trip over hydraulic hoses. Injury may result. To minimise danger
ensure that these lines are not run across walkways, ladders, roadways and doorways, etc and that people
likely to pass through the working area are aware of the danger.
To prevent entanglement with moving parts operators must not wear loose clothing, ties, jewellery etc…
Long hair must be tied back.
Always keep hands, fingers and body parts clear of the reaction foot at all times. Trapping in this area can
result in serious personal injury.
Before use, check the hydraulic hoses are not cut, split, kinked or damaged in any way. If in doubt Do not
use.
All hydraulic equipment and ancillary products should be inspected for damage and irregularities prior to
use. If in doubt Do not use.
Never lift or drag hoses or cables. This weakens the swagings and puts unnecessary stress on threads and
fittings. Subsequent failure may result in causing injury.
The end user of this equipment should carry out their own risk assessments prior to operating.
CAUTION: ANY MODIFICATION TO THE EQUIPMENT OR CHANGE OF USE BY
ANYONE OTHER THAN W. CHRISTIE WILL INVALIDATE W. CHRISTIE

ASSEMBLY
Push the Reaction arm onto the Hyspan Gearbox Serpentine and retain in place using spirolox clip.
Secure the impact socket to the wrench square drive using ring and pin combination
Ensure that the assembled wrench and socket fits comfortably on the application and there are no
restrictions to the fastening operation.
Connect the hoses to the hydraulic couplings on the Hyspan, ensuring the fittings are connected
correctly. (Refer to Typical Connection Layout on next page)
Connect the hoses to the power pack, ensuring the fittings are connected correctly. (Refer to

TYPICAL CONNECTION LAYOUT
TORQUE REACTION
When the Christie Hyspan Wrench is in operation the reaction arm rotates in the opposite direction to the
output square drive and must be allowed to rest squarely against a solid object or surface adjacent to the
bolt to be tightened. (See figure below).
Ensure the Reaction Arm is NOT resting on a sloping or bevelled face.
SPECIAL NOTICE - TIGHT FASTENERS
When tightening or releasing tight fasteners, the torque required to move the nut may be high enough to
keep the reaction locked in one position. This can cause the reaction plate to bend or cause gearbox
failure. To prevent failure, re-position the reaction plate after every two turns of the fastener, i.e operate
the tool briefly in the opposite direction.

SAFE REACTION ZONE
Care must be taken to ensure that the reaction arm is only used within the limitations shown in the figure
below. Failure to observe this instruction will result in premature wear or damage to the wrench. Do not
react on the reaction arm vertical crank. Extreme forces are created which may cause damage to the
wrench. If the application does not allow the use of a standard reaction arm, non-standard reaction arms
are available.
Customers must not modify reaction arms and are strongly advised to contact W. Christie (Industrial) Ltd
for technical assistance.

SETTING TORQUE AND OPERATING –TORQUE TIGHTENING
1. Ensure that the tool has been assembled as per the “Assembly” section.
2. Determine the required hydraulic pressure for the desired torque (See supplied calibration graph –
do not exceed maximum hydraulic pressure)
3. Set the hydraulic pressure.
4. Set the direction selector to the forward direction (test by briefly pressing the trigger and releasing
to ensure correct direction)
WARNING:- KEEP HANDS CLEAR OF REACTION.
5. Position the Hyspan tool onto the application, ensuring correct reaction (See “Torque Reaction”
and “Safe Reaction Zone” sections)
6. Press and hold the trigger.
-When tightening the hydraulic motor will stall out when the fastener is tight.
7. Release the trigger.
8. Remove the Hyspan tool from the fastener
Note –It may be necessary to set the tool to reverse and blip the trigger to enable it to be removed.
SETTING TORQUE AND OPERATING –TORQUE LOOSENING
1. Ensure that the tool has been assembled as per the “Assembly” section.
2. Determine the maximum hydraulic pressure for the wrench from the calibration graph –do not
exceed maximum hydraulic pressure
3. Set the hydraulic pressure.
4. Set the direction selector to the reverse direction (test by briefly pressing the trigger and releasing
to ensure correct direction)
WARNING:- KEEP HANDS CLEAR OF REACTION.
5. Position the Hyspan tool onto the application, ensuring correct reaction (See “Torque Reaction”
and “Safe Reaction Zone” sections)
6. Press and hold the trigger.
-The fastener should loosen.
7. Release the trigger
