8.15. WARNING

Ensure that you set the speed of the attendent control to a
speed that you can comfortably follow.
Ensure that you always have comfortable access to the con-
trols whilst the chair is moving and make sure that the control-
ler is fixed securely to the chair.
It is important that the joystick boot is replaced if it is torn or
brittle, failing to do so could cause substance damage to the
controller and unexpected movement of the chair.
Always turn off the power to the controller when leaving the
user in the chair.
Do not replace the joystick knob with any unauthorised item. It
may cause hazardous operation and loss of control of the
chair.

Before adjusting the swing-away arm, switch off the controller
to avoid accidental displacement of the joystick which would
cause unwanted movement of your wheelchair.
Keep your fingers and clothing, etc. clear while operating the
swing-away mechanism.
Be aware that the width of you chair has increased if the
swing-away arm is out and you may not get between certain
obstacles.
Do not hang any items on or over the parallel swing-away
remote assembly as this could damage the swing-away
mechanism.
When transferring to and from the wheelchair do not use the
remote as a means of support.
Keep fingers, clothing, etc. clear of the swing-away mecha-
nism at all times.
Ensure the power is switched off while adjusting the parallel
swing-away arm.
Only operate the wheelchair at low manoeuvring speed when
the parallel swing-away is in use.

9. Batteries and charging

9.1. Batteries

The batteries are contained within the drive unit located under the
battery shroud. To remove the batteries, should they require chan-
ging or maintenance, first release the two handle screws under the
front of the seat frame (Fig. 65), which connect the seat frame with
the seat module interface. Release and hold the safety locking pin.
Flip the seat frame backwards
the safety bar like the bonnet of a car
lid. Disconnect the 2 pin Andersen connectors from each battery
(Fig. 63, 64 and 67). There are straps available on each battery
where they can be lifted out. To fit the batteries please proceed in
the opposite way.

9.2. Safety cut-outs

In the event of a short circuit there are several safety systems built
into your wheelchair to safeguard your electrical circuits.
1. Fusible 100A links are connected in to the battery harnesses to
prevent short battery circuits
2. 15A auxiliary power circuit fuses for the Q-MAC module and the
Recaro power supply
3. A 70A re-settable fuse in the main controller power harness.
This is on the front shroud of the MWD and on the shroud bet-
ween the castor wheels on RWD/FWD chair.
To replace them contact your local Sunrise Medical supplier, who
will also diagnose the fault.

9.3. General Battery information

Batteries are the power source for almost all of the modern mobili-
ty products available today. The design of batteries used in mobili-
ty products is significantly different to the batteries used to start a
car for example. Car batteries are designed to release a large
amount of power over a short period of time, whilst mobility batte-
ries (commonly called deep cycle batteries) release their power
evenly, over a long period of time. Therefore, due to the lower pro-
duction volumes and increased technological requirements, mobili-
ty batteries are typically more expensive.
Commonly two 12 volt batteries are used together in a mobility
product, giving a total voltage of 24 volts. The size of the battery,
(e.g. its available power) is expressed in amps per hour e.g.
70amp/hr. The higher the number, the bigger the battery size,
weight and, potentially, the greater the distance you can travel.
Sunrise Medical only fit as standard maintenance free batteries
into these types of wheelchairs.

9.4. Maintenance free batteries

This type of battery uses a method of carrying the electrolyte com-
monly referred to as 'gel', that is held within the battery case. As
the name implies, no maintenance is required other than regular
charging. You can safely transport this type of battery without fear
