Danger areas
:
Never place your hand or fingers between the DMA

4.2.2 Starting procedure hydraulic power unit
Procedures
-
when first putting the tool into operation
-
when changing Torque Wrenches at the hydraulic unit
Do not exceed the determined maximum nominal
pressure or torque of the Torque Wrench, square
drive inserts, and other spare parts you are us-
ing, when adjusting the hydraulic pressure or the
torque.
Non-observance may cause damage to property
or personal injury.
Observe the enclosed data sheets/torque tables
of the alkitronic® Hydraulic Torque Wrenches.

Use High Pressure Quick releasing couplers for
quick connection of Torque Wrench to the hose and
pump. Make sure that the spring-loaded retaining
rings are fully engaged and the safety rings are
tightly threaded against the spring-loaded retain-
ing rings to prevent the connectors from disengag-
ing under pressure.
4.2.3 General description tightening/loosening
The following is a general operation manual. The
operation manual applies exclusively to the hydrau-
lic power unit being used. The operator must read
and understand this operation and maintenance
manual before operation or maintenance.
• Set hydraulic power unit in operation according to the
operation manual.
• Carry out pressure adjustment at the hydraulic power
unit according to torque chart of the alkitronic® Hydraulic
Torque Wrench (see example page 12 above, Fig. 4).
• Activate the torque tool a couple of times before connect-
ing to bolt/nut to ventilate hoses and the tool, if necessary.
Make sure function is faultless.
• Connect the Torque Wrench with the bolt/nut and start the
bolting process. The reaction surface (H-AX hex link) or the
reaction arm (DMA) of the Torque Wrench will move against
the support point and the bolt/nut will begin to turn.
Observe the safety instructions and danger areas,
see item 4.2.1
• Keep pressing the remote control button of the hydraulic
pump until the drive of the alkitronic® H-AT or H-AX stops
turning. The pre-set pressure is reached.
• Then press the button on the remote control once or twice
until the previously set pressure is reached (recommended
to ensure that the applied torque is transferred to the bolt
connection and that the Torque Wrench does not just stop
at the end stop of the hydraulic piston).
• Check the pressure gauge on the hydraulic unit to ensure
that the set pressure has been reached.
Re-positioning the Torque Wrench
to the next bolt connection may not
be possible due to the high torsional
force.
Apply pressure again (possibly 5
bar more than set). Press the release
latch down. Now the ratchet ele-
ment and the Wrench are released.
