4. Emergency Stop (Electric only)
The red Emergency Stop Button is located on the rear of the control box and is activated by
pressing in. This will cut all power to the lift and only be reset by twisting the button counterclockwise
and releasing.
5. Emergency Lower/Raise
Emergency lower/raise buttons are provided at the rear of the control box. This is operated by
inserting the tip of a ball point pen into the button highlighted "lower/raise". This will bring the boom
down/up should the hand control fail at any time.
6. Mechanical Emergency Down (Electrical Down)
In the case of a complete electrical failure the electric actuator is fitted with mechanical lowering
device (RED BOSS). This will only operate when the lift is under load. The device must be pulled
upwards to activate and a slow decent will commence.
Note: The MINIMUM load required to manually lower the hoist using the mechanical emergency
down function is 30 kg.
7. 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. CAUTION: DO NOT IGNORE THIS WARNING
ALARM. Complete the lifting operation and place the lift on charge (see charging instructions).
8. Raising and lowering the boom (hydraulic models)
WARNING
Never loosen or unscrew the retaining bolt of the hydraulic jack unless you are an authorised
competent engineer. Never load whilst user needs to rotate hydraulic jack. If the user
intends to rotate the jack strongly, it may impact the patient or cause unforseen danger to
patient and/or caregiver.
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 silver star shaped knob, and
the pump handle which is a long lever on the side of the hydraulic unit to raise the boom. The
valve is closed by gently turning the 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. To lower the boom, turn the release valve
anticlockwise. The release valve is progressive, the more it is opened the faster the descent.
The valve is restricted so even when fully open the descent is controlled. This facility allows for a
"hands free" descent. If the release valve is opened a fraction (a quarter turn) a very slow speed
of descent will allow the caregiver to work "hands free" while assisting or comforting the patient.
REMEMBER to close the release valve before commencing lifting operations. The release valve
only requires gentle pressure to open or close. DO NOT apply excessive force to the release
valve, either to close or to open. It is not necessary and will only damage the valve.
