Battery maintenance
When storing for longer than 1 week, you are recommended to disconnect the lift from the battery via the
main switch or by releasing the lift's main fuse, in order to reduce the risk of the battery discharging. The
length of time the vehicle can be stored without the battery's charge level becoming too low depends on the
condition of the battery, the charge level before storage and how much power the vehicle's other components
take from the battery. After a period of storage, the battery must always be charged fully before operating the
lift.
When installing the lift and when carrying out service and repair work, when the lift is operated repeatedly
without the vehicle being started and used, the battery charger must be used between operations to maintain
the battery's charge level.
NOTE!
The battery charger must not be connected when operating the lift. Risk of damage.
