2) Turn on the hall call by inserting the key and turn it to the on position.

3) Call or send the seat by pressing the appropriate direction to the hall call.

4) The lift will drive as long as the directional button is being pressed and stops after releasing the button or when arriving in the landing station.

5) Press the directional button until the seat automatically stops at the landing stop.

6) Turn the key on the wall controller and take it with you.

Hall calls are usually supplied with two 1.5V AAA batteries. Battery life time is approximately one year, so the battery can be replaced during regular service visits

(1 maintenance visit minimum every 12 months).

Battery function can be checked at any time. Each hall call has a green LED which flashes after being activated. If the LED indicator is off, the battery must be replaced.

Charging the battery

The two 12V batteries that power the chairlift are charged at each landing station using the AC charger. The seat must therefore always park in one of the landing stations.

The seat is equipped with the following audio signals:



If the seat stops outside the station and thus is not charging, after 5 seconds every second a short beeping sound will appear. Take the platform to some of the landing stations so it can charge. The acoustic signal should then stop. If not check if the charger is plugged in and there is 24V between the charging plate and the rack on the rail. If the problem persists please contact the installing company.



If the battery capacity is low or insufficient for further trouble-free operation every

2.5 seconds a long beep will appear during driving of the chairlift. In this case park the lift in the landing station for some time in order the batteries can recharge.

Fault detection and trouble shooting

The lift is equipped with a number of electrical and mechanical safety features. If the lift is not working check the following points:



Is the green main power LED next to the main power switch on the carriage on?



Is the armrest folded down for driving while sitting on the seat?



Is the hall call LED on when trying to call or send the lift? Check batteries.



Is the swivel lever properly enganged a the 0° driving position?



Are any of the contact safety covers pressed. Check side covers, footrest cover as well as covers on the upper and lower trolley (plastic covers around the rail)



Is driving in both directions blocked or only in one direction?



Is the main power supply to the charger ok? Check fuses.



When calling the installation company please have the serial number of the lift ready.

Emergency drive wheel

In case the chairlift stops working on the driveway the unit can be moved by turning the emergency handwheel. The handwheel has to be entered on the front of the drive unit into a hole next to the main power switch. Before using the handwheel turn off the main power switch.

The handwheel has to be pushed into the hole with a certain force and can then be turned in the desired direction. The movement of the unit will be slow and the lift should be moved to the nearest acceptable position.

Maintenance

Regular maintenance of the entire stairlift is particularly important. The minimum inspection intervals (also with minimal frequency of usage) are:

• 1st service inspection after about 6 months after commissioning.

• Additional inspections depending on usage, but at least every 12 months.

Check regularly, at least once a week following points on your seat:



The seat should not start if the armrest with the operation is in the raised position.



The lift should not start if the seat is not in the 0° rotation position.



Check functions of all contact safety covers on trolleys, footrest and on the side of the carriage. These covers must stop the lift when being pushed in the driving direction.



Check all visible parts for damage or deformation.



If you release the joystick or the push button the lift must immediately stop.



Regularly clean the rails form dust and other dirt.



Keep the area around the rails and the chair travel way free of any obstacles.

Cleaning:

Before cleaning you must always turn off the main power switch. To clean the whole device use a damp cloth and ordinary non-abrasive household cleaners. For cleaning the upholstery material of the seat and the backrest also use a damp cloth to remove dirt.
