3.2.2
Cleaning the batteries
Dry batteries are maintenance free. Still, you have to pay attention to the following matters:
•
Keeping the batteries clean and dry: dirt and water may cause a leak, causing the capacity of the
batteries to decrease.
•
Cleaning the terminals: after cleaning, grease them with acid-free Vaseline.
Never completely deplete the batteries! This can seriously damage the batteries and considerably
decrease their life span.
3.3
Driven wheels
To ensure proper operation of the wheelchair, it is very important that the tyres are kept at the correct pressure.
Soft tyres yield less than optimum driving for the wheelchair. It also takes more energy to move the wheelchair
forward, putting a heavier load on the batteries. Moreover, when driving on soft tyres, tyre wear is unnecessarily
great.
See 'technical specifications' for the correct tire pressure.
When pumping the tires up, note that the pressure may never exceed the maximum specified value
provided in the 'technical specifications’ table, or as indicated on the side of the tire.
When in doubt, contact your dealer/supplier.
See the 'maintenance table' for the inspection of the tyres.
3.3.1
Tire repair on driven wheels
When repairing or replacing an inner tube on a driven wheel, the neutral should not be switched off, so that the
wheel does not turn.
Repair a flat tyre as follows:
•
Support the wheelchair so that the wheel is off the ground.
•
Pull out the valve to completely deflate the tyre.
•
Unscrew the central wheel bolt with box spanner 17 and remove the wheel.
•
Loosen the Allen bolts using an Allen key with a width of 6 mm.
Remove the front of the rim half.
•
Remove the inner tube and the tyre from the rim.
•
Remove the inner tube from the tyre, for repair or replacement.
•
Repair the inner tube or replace it.
