• By pressing the EMERGENCY OFF switch, it locks
into position. The drive unit is interrupted and can
no longer be operated with the manual switch. It is
activated in emergency situations and if the proper
operation of the device is impaired.
• By turning the EMERGENCY OFF switch in the di-
rection of the arrow, it pops back out and is thus
released. The drive unit can then be operated
again using the manual switch.
12. Manual switch
• The manual switch is used to activate the drive unit
(stepless adjustment) and activates the “lifting”
and “lowering” of the arm.
• For the desired action, the respective button must
be pressed and held. When releasing the button,
the drive unit stops automatically.
Lifting
Lowering
• As an alternative, the linear drive can also be ex-
tended (lifted) using the button (1) on the control
unit and retracted (lowered) with the electrical
emergency lowering (2). See 12.1.
13. Braking function of the rear
castors
• The two rear castors are provided with an im-
portant safety feature for using the device. The
rear castors are equipped with a locking brake and
an anti-swivel protection.
Attention - risk of tipping over!
Always both rear castors must be
locked.
• Press down the
lever in the front area with
your foot. The castors are
then braked and secured
against swivelling.
• Make sure that the
castors do preferably not
point inwards.
• By actuating the
lever in the rear area, the
brakes are released again.
14. Emergency lowering
14.1. Electrical emergency lowering
• If the manual switch is out of order due to a defect,
but the electrical system is still functioning (battery
is sufficiently charged), the linear drive can be re-
tracted using the EMERGENCY lowering button.
For lowering, keep
and hold the button.
14.2. Mechanical emergency low-
ering
• If the patient becomes exposed to an emergency
situation, an electrical defect occurs at the drive
motor, the control unit fails or the rechargeable
battery is completely discharged, it is necessary to
use the mechanical emergency lowering.
Before using the emergency lowering, press the
EMERGENCY OFF switch!
Attention - risk of injury!
When using the mechanical emergency
lowering, do not stand under the arm.
