Operation and Maintenance Manual
3.
Commissioning
The high-pressure hoses and all couplings, fit-
tings and connections must be checked for integ-
rity and cleaned if necessary before each start-up.
Dirt particles in the hydraulic system lead to mal-
functions and breakdowns. The hydraulic hoses
are to be designed with a large radius so that there
is no risk of accidents. Do not kink, step on, drive
over or damage mechanically.
The Hydraulic Pump must not be operated with-
out connected hoses and hydraulic torque tools!
NOTE!
Check the oil level in the
sight glass.
The correct oil level must
be displayed in the area
between the maximum
and minimum mark.
If necessary, the hydraulic
oil (grade, see 1. technical
data ) can be refilled after
removing the bolt con-
nection (5).

1. Connect the hydraulic hoses of the hydraulic wrench to
the LEVA Hydraulic Pump (K), see also connection diagram,
point 9, page 10.
It is particularly important to ensure that all couplings are fully
and securely coupled so that no hydraulic oil escapes and the
oil flow is not impaired.
2. Connect remote control (F)
3. Important safety instructions
The hydraulic hoses must be provided in pairs with
plug-in coupling and plug-in nipple, so that the
forward (pressure) and return are unmistakably
applied to the piston or rod side of the hydraulic
cylinder of the hydraulic wrench.
If there is an interruption in the return line, a large
excess pressure on the rod side of the hydraulic
cylinder can form, which can destroy the hydrau-
lic wrench and cause serious physical damage to
people.
In general, when creating bolting connections, the
manufacturers instructions for use of the wrench
must be given equal priority and the regulations
or specifications of the corresponding construc-
tion must also be followed with priority.
.
Before bolting with the LEVA Hydraulic Pump
a function check with max. 100 bar operating
pressure (procedure see point 4 and 4.1) must be
carried out.
