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.
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.
