7.3 Tires
7.3.1 The condition of the tires is affected by the way you drive and use your
wheelchair.
7.3.2 Inspecting Tire Tread: please check the tread depth regularly. Replace the
tires when the tread depth is less than 1.0mm.
CAUTION
● When the tread depth is below 1.0 mm, the tire does not have good
traction. This may lead to vehicle slippage and makes braking distances
much longer. Thus, go to your Karma dealer to replace the tire as soon as
possible if it has less than 1.0 mm tread depth.
● The tire pressure must be kept at between 40-50 PSI (approx. 1.8 kg/cm or
2.75~3.45 bar=275-345 kPa) for the best drive range (maximum distance
travelled per charge) and usage/ handling.
7.4 General Maintenance
7.4.1 You must maintain the vehicle more frequently if you drive on grass, sand
or gravel roads often.
7.4.2 Do not use water, oil or other chemical solutions to clean your wheelchair.
Be sure NOT to spray the vehicle with water, as not to damage the
electronic components and PCB circuit board.
7.4.3 Please clean the vehicle by wiping it with either a dry or moist cloth.
7.4.5 Please take the vehicle to an authorized KARMA wheelchair dealer for
repairs and adjustments. Improper adjustments could lead to wheelchair
malfunction or an accident.
7.4.6 Please use a soft and dry cloth to keep your wheelchair clean. Use
moderate or mild detergent to clean the wheelchair, if necessary.
