14.5 Maintenance of the Charging Contacts for the Radio Remote Control
•
Clean the contacts of the radio remote control and the charging station at regular intervals
(depending on the stress and environment), e.g. with some steel wool or fine sandpaper.
•
Afterwards, we recommend wetting the contacts with a little contact spray.
14.6 Vacuum Pump Maintenance
Figure 23: Vacuum pump
For optimum function and suction performance, the vacuum
pump should be maintained at regular intervals. The mainte-
nance intervals depend on the respective use and the ambient
conditions.
Before maintenance, the vacuum pump must be
disconnected from the power supply by a qualified
electrician and removed from the blue housing by
a mechanically trained specialist.
•
First check the filter cartridges ( F ). Depending on the amount of dust, they may need to be cleaned. To do
this, blow through the filter from the inside to the outside with compressed air (do not wash it out).
→
Clogged, oily and greasy cartridges must generally be replaced with original spare parts.
•
Blow out any dirt in cooling air ducts ( K ) carefully with compressed air.
•
Now remove the side cover ( D ) by loosening the screws.
•
The sliders ( S ) are subject to wear due to abrasion on the housing. Check the width of the sliders with a cali-
per gauge after 3,000 operating hours at the latest or at least once a year.
→
The width of the sliders must be at least 12.5 mm. If not, contact customer service.
→
If sliders need to be replaced, simultaneously blow out the housing with dry compressed air.
•
The roller bearings integrated in the pump are maintenance-free and lubricated for life. Defective bearings
may only be replaced with original parts from the manufacturer.
15 Decommissioning
•
For decommissioning, the supply batteries must be disconnected by a qualified electrician.
•
Avoid deep discharge of the two lead-acid batteries. If the Mobile Lifter is only to be taken out of service
temporarily or stored for a longer period, the batteries must be fully charged before storage and at regular
intervals. The trickle charge level of a battery is 12.5 V. If the voltage drops below this value, a recharge is
recommended.
•
For recommissioning, observe chapter

10 “Installation and commissioning“.
•
For the final scrapping of the Mobile Lifter, please refer to chapter

