6.3.2
Tightness of the Hydraulic System
All components of the hydraulic system must be checked for leaks. If oil
leakage can be detected at the following points, the lift must not be operated
any further and the MAHA Service Center must be contacted:
•
Floor of the installation box or pit floor
•
Wiper ring on the piston rod
In the event of oil leakage at the following points, the screw connections must
be retightened to a torque of 45 to 50 Nm:
•
Hose fittings/valve fittings on the hydraulic block
•
Hose fittings on the lifting units
If oil leakage can still be detected, the lift must not be operated any further and
the MAHA Service Center must be contacted.

Yearly Inspection
There are country-specific requirements for the regular inspection of lifting
equipment. These generally require an inspection of the safe operating
condition after 12 months at the latest.
Irrespective of these regulations, the following items must be checked at least
every 12 months and corrected if necessary.
6.4.1
Welded Joints
All accessible weld seams shall be visually inspected for irregularities, such as
cracks or corrosion. In the event of such an irregularity, do not continue to
operate the lift under any circumstances. The MAHA Service Center must be
contacted immediately.
6.4.2
Tightening Torques
To ensure the stability and function of the lift, all screw connections must be
checked and tightened if necessary. The tightening torques can be found in the
technical handbook of the lift.
6.4.3
CE Stop
The CE stop is a programmed intermediate stop approx. 120 mm above the
lower end position, which is approached during each lowering process to the
lower end position. It alerts the operator to the pinch point between the
supports and the floor and gives him the opportunity to make sure that there are
no people or tools under the supports.
When lowering, the lifting movement must stop automatically at approx.
120 mm. After releasing and pressing again, it must be possible to move on to
the lower end position.
6.4.4
Hydraulic Hose Line
The components of hydraulic hose lines are subject to natural aging. To prevent
failure at an early stage, hydraulic hose lines must be checked for at least the
following criteria:
