Introduction
The U-Drive system is designed to attach to
a user propelled wheelchair to turn it in to a U-Drive. The U-Drive system can either be removed or put in to neutral to allow the user to propel the wheelchair manually.
The U-Drive system is designed to work in
conjunction with specific wheelchairs. The list of wheelchairs your model will fit is available from Drive Medical.
The U-Drive is controlled by the wheelchair
user independently.
The U-Drive uses a 24V 12ah battery pack,
which uses 2x 12V 12ah sealed lead acid batteries (supplied).
The U-Drive is manufactured by Drive
Medical Ltd and is CE marked. Drive Medical Ltd is an ISO 9001 and ISO 13485 certified Medical Device Manufacturer.
Safety Procedures
Ensure the U-Drive is installed as far to the
front of the wheelchair frame as is possible.
When connecting / disconnecting the
battery from the U-Drive or the charger make sure both the power to the charger and U-Drive joystick are switched off.
Ensure the U-Drive is secured in transit. It is
also recommended that the battery is disconnected.
Ensure that the battery is charged only with
the battery charger supplied with the U­Drive. Using another battery charger may cause damage or injury.
Whilst the U-Drive has been EMC tested, it
may be susceptible to certain types of electromagnetic waves. Avoid close proximity to mobile phones, commercial
broadcast towers and emergency services’
radios. Other household appliances are not known to pose any such risk. If involuntary movement occurs, switch off the U-Drive and report this to your dealer.
The U-Drive should not be used when it is
snowing or during heavy rain. This may cause damage to the U-Drive. The U-Drive should not be exposed to damp conditions or direct sunlight.
Ensure the strap is hooked on to the left
hand wheelchair push handle and is taught to prevent the U-Drive from dropping when driving over pot holes, etc.
Before Driving
The user needs to be familiar with the use
and operation of this U-Drive before driving.
Ride on the pavement and pedestrian areas
only. Never ride on motorways or dual carriageways. Only use roads to cross to other side of the pavement.
U-Drive IFU Page 2 Issued 10/11
Be aware of traffic when crossing or using
roads.
Use extreme caution when driving your U-
Drive in busy areas such as shopping malls.
Do not drive the U-Drive under the influence
drink or drugs, or when you are tired.
Be careful when using the U-Drive in low
light. It has not been designed for use at night.
Before using the U-Drive in busy or
hazardous environments, familiarise yourself with the operation of the U-Drive. Practice in an open and safe area which is free from hazards and other people. Use a low speed for your initial practice.
Always remain in the wheelchair seat whilst using the U-Drive. Do not stand on the footplate.
Whilst Driving
Do not use your U-Drive on surfaces that are
muddy, gravelly, bumpy, narrow, snowed over, icy; or on towpaths near to canals which are not guarded.
Do not use your U-Drive outside when it is
raining, snowing, misty or windy.
Do not make erratic turnings on your U-
Drive.
Bear in mind driving motions such as
accelerating, stopping, turning, reversing, and the effect of gradients.
Slow down when driving on gradients.
Always lean forward when climbing a steep gradient. Do not travel on gradients exceeding those stated in the specification. Most access ramps are 5º which is a suitable incline for the U-Drive.
When climbing an incline, try to keep your U-Drive moving. If you must stop, start up again slowly, and then accelerate cautiously. When driving down an incline, do so slowly and in the forward direction only. If your U­Drive starts to move faster than you anticipated or desired, allow the chair to come to a complete stop by releasing the joystick. Push the joystick slightly forward and continue travelling slowly down the incline. When climbing an incline, do not zigzag or drive at an angle up the face of the incline. Always drive your wheelchair straight up the incline. This greatly reduces the possibility of a tip or a fall.
Do not drive on roads with large drops or
potholes.
The U-Drive is not suitable for carrying
passengers.
Do not use the U-Drive to carry heavy goods.
Do not use a mobile phone or other wireless
communication devices whilst driving. Always stop somewhere suitable and switch off the U-Drive before using the phone.
Do not set in freewheel mode when driving,
especially on a gradient. Ensure that the U­Drive’s automatic brakes are applied before use.
Do not exceed the weight limit of the U-
Drive.

Installation Instructions
Note: Installation should be completed by a
Drive Medical Specialist Dealer.
1. Joystick Installation
Using a hex key, undo the sections of the clamp. Attach the two silver sections around the armrest tubing, ensuring the section with the tapped holes is inwards. (Photo 1).
Position the black joystick receiver against the outside silver clamp. Turn until the tubing of the receiver is horizontal. Reattach the screws using the hex key. (Photo 2).
Loosen the knob on the side of the tubing and slide the tubing attached to the joystick inside the receiver tubing.
Position the joystick as required by the user and secure by retightening the knob, as shown in the photo 3.

2. Bracket Installation
Install both brackets at the front of the horizontal tube of the wheelchair frame, ensuring the white nylon part is pointing towards the rear of the chair (as shown by the photo above).
When installing the brackets:
a. Ensure the white nylon section of the
brackets are inside the wheelchair frame and point towards the rear of the frame
b. Ensure the brackets do not interfere with
the front castor wheels. Test this by swivelling the castor forks and checking all parts are clear of the brackets.
c. Ensure that the brackets are positioned
exactly opposite each other so the U­Drive mounting bar is straight and easy to push in to the bracket. If required, use the measuring bar to check the brackets are correctly positioned before securing on the tubing.
3. U-Drive Unit Installation
Position the U-Drive unit behind the wheelchair and ensure that the motors are in the DRIVE position. Operate the lever marked “Press or Pull” and push down the yellow handle on the other lever to retract the round pegs on the horizontal bar on the front of the unit (as shown below).
Pull back the wheelchair and position so that the mounting bar slides in to the brackets on the wheelchair frame (as shown below).
