Operation
4.1
Connecting hydraulic hoses
The nipple at the two-hose-system is the connection for
Advance (A). The coupling is the connection for Return (R).
Original alkitronic® hoses, couplings and hydraulic power
units are designed to guarantee a correct connection.

Do not lift or carry the alkitronic® Hydraulic Torque
Wrench by the hoses. Before start-up, clean hoses
and nipples/couplings. Check for damage and pos-
sible need for replacement. Place hydraulic hoses
flat on the ground. The hoses must not be bent,
twisted, stepped on, driven over or mechanically
damaged.
Contamination of or damage to the hydraulic sys-
tem may lead to malfunctions or operational failure.
Inspect Torque Wrench and hose assemblies for
damage and wear at regular intervals. If possible,
before each use. Inspect hose sets in unpressurised
condition. Use implements when necessary. Defec-
tive or damaged hose assemblies must be replaced
immediately. Do not attempt to repair them. Always
use new components.
To avoid hydraulic oil escaping under high pressure,
make sure all hydraulic hoses (coupling and nipple)
are properly connected and secured with the
Hydraulic Pump and the load (motor, cylinder or
Torque Wrench).
Do not make improper modifications of the hy-

draulic hoses/couplers. Interchanging quick-lock
couplings will reverse the flow direction and the
control of the load. Non-compliance with these
regulations may lead to faulty functions and dam-
age to the tool or serious injuries to the operator.

Tightening and loosening
4.2.1 Safety instructions
Comply with all applicable local and safety regula-
tions when putting the tool in operation.
Inspect and test all components for damage. Do
not operate with damaged parts!
Keep clearance for the hoses, swivel and couplings.
Do not operate the alkitronic® Hydraulic Torque
Wrench unattended under any circumstances.
A rapid "switch off" in case of emergency must
always be ensured.
Maintain a safety distance. If a bolt rotates freely,
the tool or the bolts may be ejected uncontrollably
from the threaded connection and may cause life-
threatening injuries.
Beware of free rotating drive parts. Always keep
clothing, jewellery, long hair, and cables away from
moving parts.
Do not touch the DMA, moving parts, or the hoses
during operation!
The DMA support must always be safe and stable
to ensure correct reaction support.
For individual solutions your alkitronic® Partner will
be pleased to assist you.
Always place drive inserts or adaptors (e.g. STABI,
STACO, STA) completely on bolt/nut and keep the
drive in axis line to the bolt during the bolting
process.
• Improper tool operation or incorrect reaction support may
cause:
- strain breakage in adaptors, housing or drive
elements,
- faulty torque transmission,
- bruises or even life-threatening injuries (parts
splintering off).
• Non-compliance with any above items will void all war-
ranty claims.
