CONNECTING THE HYDRAULIC
WRENCH
When using hydraulic hoses for a tool and pump, make sure the hoses are rated for pressure of 40,610 PSI/2800. The
system is equipped with safety couplers which prevents the hoses from loosening accidentally.
Connect the twin-line hose as shown below. To connect the twin-line hose, make sure male couplers are connected to
female couplers. Hold the hoses as shown in the picture below labeled (A). Ensure the connectors are fully engaged and
tightened to the nal thread (B). Loose or improperly threaded couplers will prevent the tool from operating and can be
potentially dangerous if pressurized.
DO NOT USE PLIERS to tighten the couplers. Severe over-tightening can cause thread failure. Knurled sleeve on
couplers need to be hand tight only. (Please also see “Releasing the pressure”)
To loosen the couplers, turn it counter clock-wise. It is normal for a small amount of oil to drip from the couplers
when disconnected.
RELEASING THE PRESSURE
Before loosening the couplers, release the pressure in the system (There might be residual pressure). Hold the STOP
button and push the ON button on the remote control to release the pressure from the system.

FUNCTIONAL CHECK
All HYTORC pumps are supplied completely assembled and are ready to use. A HYTORC Hydraulic Power Pack,
for use with your HYTORC tools, is recommended to provide the safety, speed, pressure and portability that make the
tools more efcient and accurate.
Before using the system, it has to be checked for its function and to make sure that no oil leaks occur. Set the pump to
max. pressure of 700 bar (10,000psi) and advance and retract the tool a few times.
Before you start the pump, turn the lock nut of the pressure regulator counter- clockwise, plug the power cord into
an outlet, and use the toggle switch *(A) to turn the pump on.
Do not hold the tool in your hands while performing the
functional check!
Do not touch moving parts!
*Some models may not have a toggle switch. To start a pump without the toggle-switch, plug the power cord into an
outlet and start the pump by pushing the manual button on the remote control.

SECTION VI
SETTING THE PRESSURE / TORQUE
On manual bolting applications, the torque value has to be set with the pump pressure. Therefore, every calibrated
tool comes with a certicate. We recommend using tools that have been calibrated to increase safety and accuracy.
It is also recommended to have all tools re-calibrated once a year. To make sure that the certicate matches with a
certain tool, compare the tool model and serial number of the tool. Both, the tool model and the serial number are
engraved in the housing of the tool.
Turn the lock nut on the pressure regulator counter-clockwise. To start the pump: push the green button (A) and hold
it. To adjust the pressure, turn the pressure regulator (B) clockwise. The actual pressure is visible on the gauge at
any time.
To determine the correct torque value, refer to the torque chart on the back of the calibration certicate. The detailed
torque chart shows pressure values in steps of 20bar. After adjusting the pressure, hand tighten the lock nut on the
pressure regulator by turning it clockwise.

Applying the Torque Wrench - the Tightening Process
1. Having set your target pressure, cycle the tool three or four times to full pressure before putting it on the
application. Cycling the tool ensures that the system is operating properly and removes trapped air, if any.
2. Place the proper size impact socket on the square drive and secure properly with a locking ring and pin.
3. Place the tool and the socket on the nut, making sure that the socket has fully engaged the nut. Further ensure
that the drive retainer is engaged.
4. Make sure the reaction arm is rmly abutted against a stationary object (e.g. An adjacent nut, ange, equipment
housing etc.)
5. When positioning the wrench, make sure that the hose connections are well clear of any obstructions, and that
all body parts are safely out of harm’s way.
6. THEN, AND ONLY THEN, apply momentary pressure to the system to ensure proper tool placement. If it
doesn’t look or act right, stop and re-adjust the reaction arm.
Setting the Pressure/Torque Continued
Turn the lock nut on the pressure regulator counter-
clockwise. To start the pump: push the green button
(A) and hold it.
To adjust the pressure, turn the pressure regulator
(B) clockwise. The actual pressure is visible on the
gauge at any time.
To determine the correct torque value, refer to
the torque chart on the back of the calibration
certicate. The detailed torque chart shows pressure
values in steps of 20bar.
After adjusting the pressure, hand tighten the
lock nut on the pressure regulator by turning it
clockwise.

2. Component: The HYTORC hydraulic twin hose, with a nominal size of 6 mm (color mint-yellow).
ATTENTION: HYTORC hydraulic twin hoses with a
diameter smaller than 6mm are not suited for
explosion protection.
The twin hose nominal size 6 mm must be
equipped as follows:
a) Solid metal spring on each male and female coupling (between
coupler and tting). Each twin hose has two pairs of couplers,
and therefore four couplers
b) Equipped with a plastic remote control FBP-A5 art.-No.: 31044774
or FBP-A10 art.-No.: 33150200. Only this plastic remote control
has passed the electric charge and capacity test.
Qualied Personnel:
The bolting system may be operated only by trained and experienced personnel for explosion protection.
Conductivity:
Conductivity of the entire system is ensured by several solid metal springs,
- HYTORC Pneumatic Pump JetAIR 12.A connected securely to the hydraulic hose
- HYTORC Hydraulic Twin Hose (diameter 6 mm) connected securely to the tool
Explosion protection is guaranteed if:
The explosion protection is only guaranteed when all springs (pneumatic pump, twin hose
and tool) are attached tightly. When in doubt about the conductivity of the connection, attach
a standard multi-meter between the tool and the end of the ground wire and take a resistivity
measurement.
Ground wire:
Avoid electric-potential differences between plant and tool. Before initial
operation in explosive areas, a ground wire has to be attached between
the HYTORC Pneumatic Pump (No Electric Pump to be used!) and the plant.
The ground wire must be supplied by the operating company.
16 Leading Innovation in Industrial Bolting Since 1968
The World’s Most Trusted Industrial Bolting Systems
Final recommendation for explosion protection:
3. Component: The HYTORC hydraulic torque wrench. The torque wrench must be equipped as follows:
a) Solid metal spring on each male and female coupling (between coupler and tting).
b) The joints of the swivel on the hydraulic wrench must not be ANODIZED!
Only the polished swivel can be used!
To ensure an effective explosion protection,
it is imperative to comply with the instructions
mentioned above. It is recommended to have the
explosion proof system inspected by a
HYTORC Specialist on a regular basis.
This system should include anti-sparking
sockets and a grounded ange.

PREVENTIVE
MAINTENANCE
Preventive Maintenance -
Hydraulic Power Packs
HYTORC Hydraulic Power Packs are precision-built units and, as such, do require a certain amount of care and
maintenance.
• Hydraulic Oil
Oil should be completely changed after every 40 hours of operation, or at least twice a year. Always make sure the
reservoir is lled with uid. If additional oil is required, use only high-grade hydraulic oil.
• Quick-Disconnects
Fittings should be checked periodically for leaks. Dirt or foreign materiais should be kept away from ttings.
Clean before use.
• Hydraulic Gauge
Some gauges are liquid lled. Should this liquid level drop, it indicates external leakage, and replacement is
necessary. Should the gauge ll with hydraulic oil, it indicates internal failure and it should be discarded.
• Filter on Pump
The lter should be replaced twice a year in normal use and more often if the pump is used daily or in a dirty, harsh
environment.
• Remote Control
(Air Unit) The air line to the remote control unit should be checked for obstructions or kinks in the line periodically.
If there is a bend or break in the line, it must be replaced. The spring-loaded buttons on the remote handle should be
checked in the event of operating difculties. (Electric Unit) The rocker switch should be checked periodically if
any indication of problems exist.
• Air Valve
This valve should be checked twice a year.
• Brushes and Brush Holders
(Electric Unit) Check and replace, if worn.
• Armature
(Electric Unit) Check yearly.
