12 Regular and recurring inspections
WARNING
All tests must be carried out in an unloaded state.
Irrespective of the periodic inspections, subsequent inspections must be carried
out by the operator and user at the specified intervals. Of course, the operator
can entrust external experts with these inspections during the year. The same
applies to the rectification of any defects identified.
12.1 Daily before operating
To ensure the safety of the system during operation, the following visual and
functional checks must be carried out daily before starting work or beginning a
shift.
12.1.1 Electrical connections (HAE)
Cables and plugs must be checked for visible damage.
If cracks on plugs or cables, bent contact pins on the plug, damaged cable
sheathing or similar defects are visible, the affected component must be
replaced immediately by a qualified electrician.
The jack must be secured against use until the repair has been completed.
12.1.2 DL - Hoses
Dangerous situations can arise due to hose connections coming loose or
porous compressed air lines or malfunctions due to leaks in the air lines and
connections.
To avoid this, compressed air hoses and their connections must be checked
visually and for audible leaks.
Defective components and connections must be professionally repaired
immediately.
12.1.3 Leakage
The pit jack must be checked daily for oil leaks. Check for unusual oil leaks at
the piston seal.
Leaking seals must be replaced immediately If oil leaks from the screw
connections on the hydraulic block, the screw connections must be retightened.
if oil is still leaking, contact our customer service department and secure the pit
jack against further use.
12.1.4 Function drain/locking screw
To check, open the drain spindle and release it abruptly.
The spindle must automatically return to the closed position.
The spindle closes completely when it cannot be closed any further.
Do not apply excessive force when closing to avoid damaging the valve seat.
In this context, check the coil spring for correct seating and damage.
