At Bolttech, safety is one of our primary concerns. By following these few, simple
potentially volatile. If there is any doubt, use an air pump.
SAFETY PRECAUTIONS
Your Bolttech-Mannings torque wrench is a power tool, and as with any power tool, certain safety
precautions should be observed to avoid accidents or personal injury. The following
tips will assist you:
. Do not kink the hydraulic hoses, and be sure they're clear of any possible reaction
surface during operation.
system in the safest manner possible.
. Do not use the hoses or any hydraulic connection as a "handle".
. All in-line links are supplied with a boot. The boot is to be used as a reaction
surface. Always use a boot with a in-line link, failure to do so will cause permanent
damage to the cylinder and void the manufacturer’s warranty.
. All square drive links are supplied with a reaction bar. The reaction bar is to be
used as a reaction surface. Always use the reaction bar with a square drive link,
failure to do so will cause permanent damage to the cylinder and void the
manufacturer’s warranty.
. Be sure the reaction boot retaining clamp is fully engaged. The reaction bar or boot
should be located on a solid, secure reaction point. For added safety, remain clear
of the rear of the reaction bar or boot during operation. Also, when initially applying
the tool, pressurize the system momentarily; if the tool tends to "ride up" or "creep",
stop and re-adjust the reaction bar or boot to a more solid and secure position.
. Always use top quality impact sockets in good condition, which are the correct size
precautions, you'll be sure to obtain the most beneficial use of your Bolttech-Mannings wrench
and fully engage the nut. Hidden flaws, however, remain a possibility which could
cause breakage, so stay clear of sockets during operation.
. In most cases, the tool will allow "hands-free" operation. If the tool must be held or
steadied during operation, avoid handling the area around the reaction bar or boot.
. Electric pumps should never be used in any atmosphere which could be considered
REACTION ARM
All Bolttech-Mannings Hydraulic Wrenches are equipped with a universal reaction arm. These
reaction arms are employed to absorb and counteract reaction forces created as the
units operate. The reaction arm should always extend in the same direction of the
square drive; however, adjustments may be made to suit your particular application.
To adjust the reaction arm, unscrew the reaction arm retaining clamp and slide the
reaction arm off of the housing. Next, rotate the reaction arm to the desired orientation
and slide it back onto the housing and secure the retaining clamp.
SETTING TORQUE
With the system fully connected and the proper power supply available, find the desired
torque conversion chart supplied for your particular tool model. Read across to the
corresponding pressure. This pressure is to be set on the pump. To do so, turn on the
pump, press down on the "advance" remote control button and hold, pressure will build
up on the gauge. To adjust pressure, loosen the locking ring on the pressure regulator
valve and turn the thumbscrew clockwise to increase pressure, counterclockwise to
decrease pressure.
NOTE: When decreasing pressure, it is necessary to turn the thumb-screw to a
pressure setting BELOW what is desired and gradually increase the pressure
to the desired level.
Once the desired pressure is stabilized, re tighten the locking ring.
PRIOR TO BEGINNING TO TORQUE - PRESS DOWN ON REMOTE CONTROL
BUTTON AND CONFIRM THE CORRECT PRESSURE HAS BEEN SET.
APPLYING THE TORQUE WRENCH
Place the proper size impact socket on the square drive and secure properly with a
locking ring and pin.
Place the tool and the socket on the nut making sure that the socket has fully engaged
the nut and that the square drive is fully into the socket.
Make sure the reaction arm is firmly abutted against a stationary object (i.e. an adjacent
nut, flange, equipment housing, etc.)
Make sure that the hoses are not placed between the reaction members.
Apply momentary pressure to the system to ensure proper tool placement.

PREVENTIVE MAINTENANCE
Tool failure does occur. Such failure is most often in the hydraulic connectors or hoses.
These items are repairable/replaceable immediately, since they are available
universally. Failure of structural members of the tool are quite rare,but replacement
parts are available from stock.
Special tools are required for the disassembly of the hydraulic cylinder and drive
mechanism.
LUBRICATION: All moving parts should periodically be coated with a good
quality molybdenum disulfide grease. Under harsh environmental conditions,
cleaning and lubricating should be done more frequently.
HYDRAULIC HOSES: Hoses should be checked for cracks and leaks after each
job. Hydraulic fittings can become plugged with dirt and should be flushed
periodically.
QUICK-CONNECTS: Fittings should be kept clean and not allowed to be
dragged along the ground or floor, as even small particles of dirt can cause
OPERATING THE WRENCH SYSTEM
By depressing the remote control button, the rear of the tool will be pushed back until its
reaction arm contacts its reaction member. Continue to hold down the button as the
socket turns until you hear an audible "click" which will signify that the hydraulic cylinder
inside the tool is fully extended and will not turn the nut any further. There will be a
rapid buildup of pressure to the point of where the pressure was preset prior to applying
the wrench.
IMPORTANT: This rapid buildup of pressure does not indicate that this pressure
(torque) is being applied to the fastener. It only indicates that the
cylinder is fully extended and can not turn the socket further until the
tool is retracted to pick up the next tooth on the ratchet wheel.
Releasing the remote control button will retract the cylinder, the tool will automatically
reset itself and the operator will hear an audible "click" indicating he can again push the
remote control button and the socket will turn. Each time the cylinder is extended and
retracted, it is called a cycle. Successive cycles are made until the tool "stalls" at the
pre set pressure (torque).
NOTE: Always attempt one final cycle to insure the "stall" point has been reached.
Should the tool "lock on" after the final cycle, push down the remote control button to
build pressure. While maintaining this pressure rotate the release mechanism and
relieve the pump pressure. This will allow the tool to be easily removed.
LOOSENING PROCEDURES
First, set the pump to 10,000 psi. Change the drive and reaction arm to the loosening
mode and apply the tool, assuring the reaction arm abuts squarely off a solid reaction
point. Press and hold the remote control button. Pressure will build up as the socket
begins to turn. Cycle the wrench until the fastener is loose enough to turn by hand.
If the socket does not turn using the above procedure, it is an indication that you will
require the next larger size tool to loosen the fastener.
