Follow The Procedure Below - Enerpac HXD-Serie Bedienungsanleitung

5.0 CONNECTING THE WRENCH TO
THE PUMP
Enerpac torque wrenches can be powered
by a range of electric or air-driven torque
wrench pumps. For complete operating
instructions, refer to the instruction sheet
included with each Enerpac pump.
IMPORTANT: It is mandatory that
the operator
understanding of all instructions,
safety regulations, cautions and warnings,
before starting to operate any of this high
force tool equipment. To ensure correct
pump and wrench control it is recommended
to use an Enerpac torque wrench pump.
When in doubt, contact Enerpac.
IMPORTANT: Minimum age of the operator
must be 18 years. The operator is
responsible for his activity towards other
persons.
ATTENTION: In case of a interrupted current
or a failure of the pump, switch off the motor
and disconnect the wrench from the pump.
DANGER: Do not use electric-
powered pumps in hazardous
environments where explosion-
proof equipment is required.
Enerpac air driven torque wrench pumps can
be used in this case.

5.1 Follow the procedure below:

1. During initial operation or start-up.
2. When changing a wrench on same pump.
3. When different torque values are needed,
using the same pump: for instance using
various interchangeable cassettes or reducer
inserts on the same wrench (tables
A2
on pages 12-15).
5.2 Pump requirements
The advance pressure (P or A) from pump to
wrench must be limited to a maximum 800
bar [11,600 psi]. The pressure relief valve at
the retract side (B or T) of the pump must be
set to a maximum 120 bar [1740 psi].
IMPORTANT: Maximum oil flow to the
torque wrench: 12 l/min @ 140 bar

IMPORTANT: See
couplers and hoses are fully connected and
oil can flow freely from (P to P) and (T to T).
Incorrectly mounted couplers can still be
closed, with the result that oil on the
wrenchs' retract side (T or R) can be
pressurized by the advance side (P or V). The
safety valve in the retract side (T or R) of the
wrench (2) will open and vent oil to prevent
over-pressurization. This valve is factory set
at 225 - 300 bar [3260 - 4350 psi].
5.3 Bleeding air from the system
During first-time operation, the hydraulic

and system is filled with air. Remove air by
connecting the THC-700 series hoses to
each other and cycling the pump using the
remote control. If the torque wrench is
connected, air can also be removed by
cycling the wrench several times.
