Please contact Norwolf Tool Works, Inc. for guidance if or when you are in doubt as to the
operation of this product with your application.
Read all instructions, cautions, warnings and notes carefully. Follow all safety precautions to
avoid personal injury or property damage during use. Norwolf cannot be held responsible for any
damage caused by improper use, lack of maintenance, or incorrect application.
The X-Driver is compatible with three styles of cartridges. The A-Drive, a fixed hex cartridge, the
V-Drive, a square drive cartridge and the M-Drive, which houses any of the following three links:
ratchet cassette, spanner and split link. The connection of the X-Driver to the A, M or V Drive
cartridge is a simple snap-in latch connection.
INSTRUCTIONS
The X-Driver™ operates in union with an air or electric hydraulic pump. The maximum working
pressure of the X-Driver™ is 10,000 PSI. Pump and hose must have the same pressure rating.
WARNING: When pressurized, the X-Driver™ links exert a great reaction force. Follow
instructions for proper tool placement. Keep reaction area free of interference.
WARNIING: Wear personal protective gear, including eye protection, when operating any
hydraulic equipment.
SYSTEM CONNECTION
The X-Driver™ connects with the pump via a double line 10,000 PSI hydraulic hose. Ensure the
connectors (couplers) are fully engaged, with no gap between the male and female fittings.
Threaded connections must be securely tightened and leak free.
WARNING: Never handle pressurized hoses. Escaping oil under pressure can penetrate the skin
causing serious injury. If this occurs seek immediate medical attention.
SETTING TORQUE
NOTE: The pump is to be controlled by the TOOL OPERATOR only.
With the system fully connected, locate desired torque on the conversion chart provided with your
tool. Set the pump to the corresponding pressure. (At this point, the tool is not on the application.)
Turn on the pump, press down on the remote control button and hold. Take reading on the gauge.
To increase pressure, loosen the locking ring on the pressure regulator valve and turn the
thumbscrew clockwise, to decrease pressure turn counter-clockwise. Once the desired pressure
is stabilized, retighten the locking ring.
NOTE: When decreasing pressure, it is necessary to turn pressure setting below what is desired
and gradually increase pressure to the desired level.
Prior to tool operation, again, press down on the remote control button and confirm the correct
pressure has been set on the pump.
NOTE: For “loosening”, set pump at 9500 PSI.

TOOL PLACEMENT
Positioning the tool determines whether the action will loosen or tighten the nut. Refer to above
diagram for correct positioning. Assure the reaction area is firmly abutted against a stationary
object (i.e. adjacent nut or flange) as illustrated.
WARNING: Make sure there is no interference between reaction points.
WARNING: Hose and fitting will rupture if reacted upon.
WARNING: Do not use swivel fitting as a handle!
Place tool on socket making sure the square is fully engaged and the drive secured with a pin.
Apply momentary pressure to the system to ensure proper tool placement. If the tool tends to “ride
up” or “creep”, stop and re-adjust the reaction area to a more solid and secure position.
By pushing down on the remote control button, the rear of the tool will be pushed back until
reaction area contacts its reaction point. Continue to hold down the button until the ratchet no
longer turns which will signify the hydraulic cylinder inside the tool is fully extended. There will be
a rapid buildup of pressure until the preset pressure level is achieved.
NOTE: This rapid buildup of pressure after the cylinder is extended DOES NOT indicate that the
desired torque is achieved. It only indicates that the cylinder is fully extended and cannot turn the
nut any further.
Release the remote control button and the cylinder will retract automatically. While retracting, you
will hear 1-3 “clicks” indicating that the tool has reset itself. Each time the cylinder is extended and
retracted is called a cycle. Successive cycles are made until the tool “stalls” (the tool will no longer
advance and no audible clicks are heard on retraction). At this point, the pre-set Torque/PSI is
achieved with an accuracy of +/-3%.
NOTE: Always attempt one final cycle to insure the “stall” point has been reached.

ADJUSTABLE REACTION ARM
The built in reaction arm is adjustable in the following manner. The “slider block” glides back and
forth along milled path and ball lock rests in either one of five milled holes. In addition, tighten the
slider block set screw to secure position.
Rotation of the arm is achieved by moving the arm along the slider block so that milled circle in the
reaction arm is aligned under the slider block which allows for 360⁰rotation. Arm is secured by
sliding the arm to opposite end. Different heights are attained by sliding arm and setting and
securing at desired height.
PREVENTIVE MAINTENANCE
Tool failure (although rare) does occur. Such failure is most often in the hydraulic couplers or
hose. These items are replaceable immediately and are available universally. Failure of structural
members of the tool is quite rare but replacement parts are available from stock.
Clean the outside of tool after use.
X-Driver Maintenance
Clean the outside of tool thoroughly. Ensure piston rod is centered vertically. Tighten all screws.
Ensure swivel port block moves freely.

V-Drive Maintenance
Clean the outside of tool. Ensure all moving parts function freely. Ensure both springs function
and both pawls move freely. Ensure latch moves freely.
After major use remove (5) housing screws and clean soiled internal parts including the ratchet
and drive plate. Re-grease with Molykote®and reassemble.
