Replacing the sensor box AA batteries
(figure 27)
Both battery compartments of the sensor box
can be opened with a PH1 (Philips) screwdriver
(2 screws per compartment) (figure 28 and 29) .
Caution!
Always replace both AA batteries at the same
time.
The polarity is clearly indicated in the battery
compartment – incorrect polarity can damage
the electronics.
Note!
Periodically check for low-bat warning of the
sensor box (see paragraph 8.1). Preventively
we advice to re-new the AA batteries every
6 months. Only use non-rechargeable high
quality batteries.
7.2 Tyres
Check the tyre pressure at least weekly (and
inflate the tyres if necessary); air pressure must
be between 6-10 bar. Tyres that are not inflated
to the appropriate level will have a negative
effect on the performance of the power assist.
Moving the wheelchair will require more energy
then, making more demands on the batteries.
Furthermore, wear on the tyres when driving
with soft tyres is unnecessarily high.
To avoid negative impact on driving behavior,
make sure both wheels have same pressure.
Caution!
Never exceed the maximum tyre pressure
that is mentioned on the tyre.
Tyres should only be replaced by a qualified
specialist – please contact your dealer.
In case of a flat tire while using the power
assist make sure to drive slowly, and try
to inflate the tyres again, or let the tires be
repaired/ replaced by a qualified specialist
as soon as possible. Using the power assist
with flat tires can damage the tyres and rims.
Caution!
Do not use massive tyres!
See technical information for appropriate tyre
type.
7.3 Cleaning
Clean the power assist with a wet towel and a
non aggressive detergent monthly.
First, wipe the dirty parts clean using a wet
sponge. Preferably use clean water or a mild
soap solution. Wipe the parts dry using a soft
dry cloth.
Caution!
Ensure that the controller is switched off
while cleaning. If one of the rims is accidently
touched, the wheelchair can start to move.
Take care with water since you deal with an
electronic system.
Never use abrasive or aggressive cleaning
agents. These can scratch the wheelchair.
Do not use organic solvents such as thinner,
petrol or white spirit.
The product should be disinfected before
re-use by a different user to prevent cross
contamination.
