It is only allowed to lift or to lower the MCS with load. Otherwise a MCS without load can cause an unequal. After it, this MCS switch-off the complete system and the red light (disturbance) is lighting.

Accordingly, the number of the lifting wheels must agree with the number of the MCS.

In the case of disturbance, raise or lower the lift only in the „single“ mode.

5.4 Lowering the vehicle (mode synchronous)

• Check the dangerous places of the lift and be sure that there are no objects or people in the immediate area of the lift or on the lift.

• Lower the lift at the height for working or in the lowest position. Press the button „lowering“ (Synchronous) at the operating unit. The MCS raises a little bit (unlocking the safety device), before the lowering starts.

• When lowering a vehicle, hold the button 2 pushed, until the lift has reached the height of 250mm; the lift stops automatically. Then push the button 2 again.

• The lift will continue lowering again. When a column stops during lowering between the height of 0 and 250mm, use button 4 to lower all columns in single operation mode to the ground (important for zeroing (referencing) the columns again). You hear an acoustic signal until the lift reaches the lowest position.

In case of an SYNCHRON ERROR (shown on display; means unequal position error of the columns) bring all columns back in the same position height, by using the buttons 3 or 4 and watching the positions on the display. When all columns are at the same height (position) again, you can operate the system again.

6.Troubleshooting

If the lift does not work properly, the reason for this might be quite simple. Please check the lift for the potential reasons mentioned on the following pages. If the cause of trouble cannot be found, please call the technical service.

Problem: The Motors does not start! Potential causes: Solution:

- no power supply check the main fuse

- the main switch is not switched on. check the main switch

- the fuse is defective check the fuse /exchange it

- the feed line is cut check the line

- the thermo-fuse is active let it cool down approx.10 min.

- the battery of the controllers is empty call the customer service

Problem: the motor starts, the lift does not lifting! Potential causes: Solution:

- the vehicle is too heavy unload the vehicle

- the level of the oil is too low refill oil

- the hydraulic valve is defective call the customer service

Problem: The MCS does not lowered! Potential causes: Solution:

- the MCS is standing on a obstacle single-mode operate

- the hydraulic valve is defective call the customer service

- the fuse is defective exchange the fuse

- the button „lowering“ is not pressed check the switch

- the holding valve is defective call the customer service

- the safety star system is always locked call the customer service

6.1 Lowering on a obstacle

The lift switched off if the lift is running onto an obstacle and out of the rule-window ± 50 mm.

6.1.1 Remove the obstacle

• Press the button “lifting ” in the single-mode. (see the chapter 5.4/5.5)

Keep an eye on it, at the singles-mode, that one MCS is lifted never too high, otherwise the crash of the vehicle can occur.

6.2 Emergency lowering

A emergency lowering is an intervention into the control of the lift and can be done only by experienced expert. The emergency lowering must be carried in this order. Otherwise a malfunction can

lead it to damages or lead to danger for body and lives.

Every kind of external leakage has to be removed. This is necessary in particular before an emergency lowering. The emergency lowering may only be done by persons which are trained in using the

lift.

Operating Instruction and Documentation

MCS 7500 Flex (Bluetooth)

- 22 -

Reasons, that can make an emergency lowering necessary, are a defect of the electric system

or disturbances of the valves, etc.

In case of power-failure or defective Valves there is the possibility through suitable tools to

lower the lift in the lowest position, so that the vehicle can be driven off.

6.2.1 Procedure of the emergency lowering

• Switch off the main switch an d safe it. (lock it)

• Remove the covers of hydraulic unit.

• Secure the dangerous place around the lift.

Pic 6: Loosen and remove the 2 lock nuts with a suitable tool in arrow

direction. Carry out this process at both columns. (Key 41)

Pic 7: The piston rod can be stuck through the dirty deposit at the

top of the hole. Use the solvent and lubricating stuff (for an example WD40) to loosen the connection. The WD40 is sprayed generously between the screw thread and the bore hole (see arrow). The time of the effect follows the contamination-degree.

Pic 8: Loosen the cap of the Minimess connection and the cap of

the tank. Fasten the Minimess hydraulic tube at the screw fitting and put the other end into the tank.

Pic 9: Use the long screw thread-bushing and turns with a suitable tool (key-wideness 24, available with your dealer,), clockwise. Lower the lifting carriage only approx. 5cm – 10 cm. Repeat the process at the next column. Lower always 5 cm-10 cm until all lift are in the lowest position. Repair the defective lift. After it create a Reset which is described in the operating instruction.

Attention!! Lower the automotive-lift only approx. 5 cm – 10 cm.

7.Inspection and Maintenance

Before a maintenance, all preparations are to enforce that with maintenance-working and repair-working at the lift no danger for body and lives and for damages of objects exists.

A regular service has to be performed in regular distances of 3 months through the operator in accordance with following service manual. If the lift is in continuous operation or dirty environment, the maintenance rate has to be increased. During daily operation the lift has to be watched carefully for ist correct function. In case of any malfunction or leackage the technical service has to be informed.

7.1 Maintenance plan of the MCS

• In case of heavy dirt deposit clean the piston rods of the hydraulic cylinders from deposit. Remove the cover of the MCS. If necessary raise the MCS with the single-mode in the highest position. Grease the piston rods with a high capacity lipid (approx. 5 g of S2 DIN51503 KE2G of the Renolit Company.

• Clean and check the moving parts. Lubricate the moving parts of the lift (hinge bolts, rolls, sliding surfaces) grease with a multipurpose lipid (example: Auto Top 2000 LTD. Agip).

• Damage to external surfaces, must be immediately repaired. If theses repairs are not made immediately, permanent damage to the powder-coated surface may result. Repair and clean damaged areas with an abrasive paper (grain 120). After this is complete, use a suitable paint (observe the RAL Number).

• Check the zinc surface and repair it with a suitable tool. Use abrasive paper (grain 280). White rust can result from moisture laying in certain areas for long periods of time. Poor aerating can also result in rust formation. Rust may result from mechanical damage, wear, aggressive sediments (de-icing salt, liquids) or insufficient cleaning. Repair and clean these areas with abrasive paper (grain 280). After this is complete, use a suitable paint (observe the RAL Number).

• Check the hydraulic tubes for leackage.

• Clean the surface of the photoelectric. (transmitter and receiver)

• Check the oil level. Fill in a clean, high quality oil (32 cst)in the tank.

• The hydraulic oil has to be changed at least once a year. To change the oil, lower the lift into the lowest position. Empty the tank and replaced clean oil, approx. 20 litres are needed. A high quality hydraulic oil is recommended, its should be 32 cst. (e.g.g. HLP 32 LTD. OEST Company)

Use a ATF-Suffix hydraulic-oil (OEST Company ) if the ambient temperature is under 5

degree centigrade. After the fill up, the hydraulic oil must be between the upper and low marking of the oil level gauge.

• Check all welded joints for cracks. If any cracks are found on the lift cease use immediately. Switch-off and secure the main switch (lock) and call the service partner.

• Check the safety device of the lift.

• Check the Battery of the controller (ASC). The Battery has a working life at notmal business between 4 ½ - 5 Years (manufacturers statement). To avoid a permanent data-loss through an empty battery, the ASC must be sent for after 4 years into the nussbaum headquarter. Please contact your service partner.

• Check the turning moment of the screws (see the list pic. 19)

7.2 Cleaning of the MCS

A regular and appropriate maintenance served the preservation of the lift. It can be a prerequisite for claims at possible corrosion. The best protection for the lift is the regular cleaning of dirt of all manner.

- Including this:

• de-icing salt

• sand, pebble stone, natural soil

• industrial dust of all manner

• water ; also in connection with other environmental influences

• aggressive deposit of all manner

• constant humidity by insufficient ventilation

How often must the lift be cleaned ?

This is dependent on the use, of the working with the lift, of the cleanness of the workshop and location of the lift. The degree of the dirt is dependent on the season, of the weather conditions and the ventilation of the workshop. Under bad circumstances it is necessary to clean the lift every week, but a cleaning every month can suffice.

Clean the lift and the floor with a non-aggressive and non-abrasive detergent. Use gentle detergent to clean the parts. Use an standard washing-up liquid and lukewarm water.

- Do not use for cleaning a steam jet cleaning

- Remove all dirt careful with a sponge if necessary with a brush.

- Pay attention that are no remains of the washing-up liquids on the lift after cleaning.

- Do not use aggressive means for cleaning the workshop floor and the automotive lift.

- A permanent contact with every kind of liquid is forbidden. Do not use any high pressure device for cleaning the lift.

8.Security check

The security check is necessary to guarantee the safety of the lifting during use. It has to be performed in the following cases:

1. Before the initial operation, after the first installation

Use the form “First security check before initiation”

2. In regular intervals after the initial operation, at least annually.

Use the form “Regular security check at least annually”

3. Every time the construction of that particular lift has been changed.

Use the form “Extraordinary security check”

The first and the regular security check must be performed by a competent person. It is recommended to service the lift at this occasion.

After the construction of the lift has been changed (changing the lifting height or capacity for example) and after serious maintenance works (welding on carrying parts) an extraordinary security check must be performed by an expert.

This manual contains form with a schedule for the security checks. Please us the adequate form for the security checks. The form should remain in this manual after they have been filled out. In the following there is a short description about special safety devices.

9.Handing over and Initiation

9.1 Regulations

• It’s not allowed to install the standard-automotive lift in a hazardous location or washing bays.

• Every solid surface is suitable as installation-place.

• An electrical supply 3~/N+PE, 400 V, 50 Hz has to be provided.

9.2 Initiation

Before the initiation a security check must be performed. Therefore use form: First security check.

If the lift is installed by a competent person, he will perform this security check. If the operator installs the lift by himself, he has to instruct a competent person to perform the security check. The competent confirms the faultless function of the lift in the installation record and form for the security check and allows the lift to be used.

Please send the filled installation record to the manufacturer after installation.
