3. Raising and lowering the boom (electric models)
The movement of the boom is achieved by a powerful electric actuator, which is con-
trolled by a simple hand control unit. The hand control has two buttons with direc-
tional arrows UP and DOWN. The actuator stops automatically at the limit of travel in
both directions. The hand control plugs into a socket at the base of the control box.
There is a hook on the rear of the hand control, which allows it to be “parked” on the
mast or boom when not in use.
4. Emergency Stop (Electric only)
The red Emergency Stop Button is located on the rear of the control box and is acti-
vated 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 oper-
ated 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 mechani-
cal 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.
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 han-
dle in the upright position when not in use.

OPERATING INSTRUCTIONS
OPERATING CONTROLS FOR THE OXFORD/HOYER ADVANCE
OPERATING INSTRUCTIONS
1. Leg adjustment
The legs on the Oxford/Hoyer Advance are adjustable for width. The legs can be
opened to enable access around armchairs or wheelchairs. For transferring and negoti-
ating narrow doorways and passages the lift legs should be in the closed position.
To achieve the adjustment, the leg adjuster pedal, located at the rear of the base, is
compressed right (DOWN) to open the legs outwards and left (UP) to close the legs.
The adjustment can be carried out with the patient in the lift, but whether loaded or
unloaded the adjustment should be made when the lift is moving.
WARNING
Never lift with the legs in the closed/transport position. The closed position
is for storage and transport only.
2. Castors and Braking
The lift has two braked castors, which can be applied for parking. When lifting, the
castors should be left free and un-braked, so that the lift will then be able to move to
the centre of gravity of the lift. DO NOT apply the brakes because if the brakes are
applied the patient might swing to the centre of gravity and this may prove discon-
certing and uncomfortable.
