6. Emergency Raise/Lower Function: The operation of this facility depends on the

specification of the actuator fitted to the hoist. Some hoists have the emergency

descent device incorporated into the actuator. These actuators have a red moulded

block at the base of the actuator ram that can be pulled up to activate the device. This

will bring the boom down slowly. The device is purely mechanical and will operate if

the hoist is without electrical power. THIS SHOULD ONLY BE USED IN

EMERGENCY SITUATIONS.

All Oxford Mobile Hoists are fitted with raise/lower buttons on the Controller. These

are located underneath the emergency stop button and can be operated by means of

inserting a ball point pen tip. This can be used to lower/raise the patient should the

handcontrol fail. Caution should be excercised when using this control as there is no

automatic cut-out of the actuator when the bottom stop is reached.

7. Batteries. The batteries are protected from deep discharge by a LOW VOLTAGE

ALARM. This will sound when the batteries need recharging and the handcontrol is

being operated. It will not sound independently of the handcontrol being operated.

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). 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.

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 carer 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.

9. Slings. The selected sling is attached to the spreader bar hooks, each sling is supplied

with instructions and they are reproduced in this manual. The instructions should be

followed carefully.

Use only SUNRISE MEDICAL LTD slings of the Quickfit, Quickfit Deluxe,

Longseat, Full Back and Access range.
