6. Operating Instructions

1. Leg adjustment
The legs on the Oxford Presence are electrically adjustable for width. The legs can be opened to
enable access around armchairs or wheelchairs. For transferring and negotiating narrow doorways and
passages the lift legs should be in the closed position.
Electric leg adjustment - is achieved by pressing the appropriate buttons on the hand control. The legs
will be locked whenever the hand control switch is released.
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. The lift will then be able to move to the centre of gravity of the lift. If the brakes
are applied it is the patient that will swing to the centre of gravity and this may prove disconcerting and
uncomfortable.
3. Raising and lowering the boom
The movement of the boom is achieved by a powerful electric actuator, which is controlled by a simple
hand control unit. The hand control has two buttons with directional 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. Repositioning the Integrated APC (Only available on selected models)
For models with Integrated APC, the electric actuator on the cradle can be adjusted using the hand
control. The hand control has two buttons depicting a seated person in two different degrees of tilt. Use
these buttons to move the cradle. The actuator stops automatically at the limit of travel in both directions.
The cradle position will be locked whenever the hand control is released.
5. Emergency Stop
The red Emergency Stop Button is located on the front 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 anticlockwise and releasing.
6. Redundant controls
All Oxford lifts are fitted with raise and lower buttons on the control box. These are located
underneath the emergency stop button and can be used to lower/raise the patient should the hand
control fail.
7. Mechanical Emergency Down
In the case of a complete electrical failure the electrical actuator is fitted with a spring
loaded mechanical lowering device (RED BOSS). This will only operate when the lift is
under load. The device must twisted by hand and released to activate. A slow decent will
commence. Repeat this process until the patient has been safely lowered.
If this feature is used, the lift MUST be subsequently checked out by a competent engineer.
8. 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).
To avoid possible permanent damage to the battery, the battery should be placed on charge as
soon as the display indicates the half empty battery symbol.
