8. Emergency lower: In the case of a complete electrical failure the electrical actuator
is fitted with a mechanical lowering device (RED BOSS). The device must be twisted
clockwise by hand to operate. A slow decent will commence. Repeat this process until the
patient has been safely lowered.
The emergency lowering device should only be used in the event of electrical
failure. It must not be used to lower the patient on a regular basis.
If this feature is used, the lift MUST be subsequently checked out by a competent
engineer.
Continued use of the hoist after using the emergency descent feature may
compromise the duty of care and safety of the patient.
9. Batteries: The batteries are protected from deep discharge by a LOW VOLTAGE
ALARM. This will sound when the batteries need recharging and the hand control is being
operated. It will not sound independently of the hand control being operated. DO NOT
IGNORE THIS WARNING ALARM. Complete the lifting operation and place the battery on
charge (see charging instructions).
10. Raising and lowering the boom (hydraulic models only): The raising and lowering
of the boom is achieved by a powerful hydraulic ram which is operated by two simple
controls. The release valve, which is identified by a black knurled knob, and the pump
handle which is a long lever on the side of the hydraulic unit.
To raise the boom, ensure the release valve is closed. The valve is closed by gently
turning the knurled knob fully clockwise. When closed, pump the long handle with smooth
even strokes for maximum effect. The handle strokes from an upright position through an
arc of 90 degrees. Leave the handle in the upright position when not in use.
DO NOT force the handle beyond the upper or lower stops. The hydraulic unit can
be rotated to allow the handle to be used from either side of the lift.
