Emergency descent device
The emergency descent valve on the lift cylinder allows the platform to be lowered in the event of an
emergency. This is possible by pulling the round operating button (1) on the emergency descent
valve (2).

In this case, if the platform is still in the extended position it must first be retracted.
2.7.8
Acoustic driving alarm/descent protection
The acoustic driving alarm sounds when the scissor lift is being driven: a warning signal will
be heard.
The acoustic descent protection sounds in the crushing danger zone below 3.2 metre
platform height (for HL-220 E12 / N-195EL12 below 3.6 metre platform height): a warning
signal sounds for three seconds.
2.7.9
Speed limiter
The speed limiter prevents the scissor lift from being driven too fast when the platform is raised.
Driving is automatically limited to the slow driving speed when the platform is at a height of
more than 3 metres. The fast driving speed becomes available again when the platform is
lowered to a height of less than 3 metres.
The driving and steering functions are automatically deactivated when the platform is at a
height of more than 8 metres. The driving and steering functions can only be activated again
once the platform is at a height of less than 8 metres.
