Driving off the Lift and Changeover • Lifts with swing arm supports: After the lift has been lowered completely, turn the support arms out to the side and bring them back into home posi- tion. • All supports: Then drive the vehicle off the lift. WARNING Contact of the support arms with the wheels or other vehicle parts during drive- off can cause damage to the support arm lock.
Emergency Lowering WARNING In the event of an emergency lowering, the safety devices of the lift are completely or partially overridden. Emergency lowering may only be performed by trained personnel. The lift must not be put back into operation until the fault has been rectified. In the event of an electrical or mechanical malfunction, two emergency lowering options are available for the lift.
4.5.2 Mechanical Emergency Lowering The mechanical emergency lowering takes place via the bleeding blocks of the lifting units. +C-M2.B +C-M2.A Remove the centre cover and store it outside the danger zone (see section “Danger zone”. WARNING The lift can/will lower on one side when the respective lowering valves are opened (tilt on one side approx.
Optional Equipment 4.6.1 Hinged Cover Frame To lower lifts with swing arm supports to floor level, they can be supplied with a hinged cover frame. NOTICE The hinged cover frame must be set in concrete with the installation box. A subsequent installation is no longer possible.
4.6.2 Installation Frame for Flat Head Lifts CAUTION In this installation situation, there is no floor compensation; when raised, this results in additional tripping hazards. This must be observed when working on the vehicle. 4.6.3 Wheel Engaging Support Lifts with a nominal load capacity of 4500 kg and above can be equipped with wheel engaging supports as an alternative to the disc supports.
NOTICE Lightly grease the sliding surfaces before mounting the wheel engaging supports. Screw the support disc all the way down (protruding at the bottom) and remove it. Position the guide plate (A) and insert the support pin (B). Screw in fastening screws (C) and tighten them hand-tight. Make sure that there is no tension between support pin and guide plate.
4.6.5 Cable Remote Control WARNING Connection only permitted by qualified electrician. The operator is responsible for ensuring that nobody is within the danger area. A cable remote control is optionally available for the lift. With this it is possible to operate the lift away from the control box. This gives the operator the opportunity to gain improved visibility into the hazardous area.

Inspection Depending on the conditions of use, the lift must be inspected at intervals of no more than 12 months. In particular, safety devices, fastenings and load-bearing components must be inspected. This inspection must be carried out by a competent person to ensure safe operation also until the next inspection. The inspection and its findings shall be documented.
Daily Inspection before Starting Work All checks must be carried out with the system in an unloaded condition! 6.2.1 Cables and Actuators Cables must not show any visible damage. Cables with visible pinch points, damaged sheathing, kinks or clanks must be replaced immediately with new ones.
6.2.5 Load Supports A = Rubber pad B = Support plate with thread Support plates take over the load and hold it in position. The rubber pad yields selectively under load. This protects the vehicle's lifting point and prevents the vehicle from slipping.
Six-Monthly Inspection 6.3.1 Oil Level and Hydraulic Oil Trouble-free operation of the lift is only possible with functioning hydraulic oil. The hydraulic oil may be non-functional if it has the following characteristics and should then be replaced immediately: • Turbidity •...
