Information on using the lockable pump
The pump lever has to be moved upwards before lifting the chair. This locks the pump shaft in position. If you lift the chair without locking the pump in position, air will enter the system and this can possible result in oil escaping. The chair starts to „bounce“. In order to remedy this effect, please act as follows:
- Pump the chair up to the highest position
- Push the pump lever down a number of times (approx. 8 times)
