MAINTENANCE
Quick-release catch on wheels
The quick-release catch on the driving wheels requires regular inspection. Check that the bearings
work properly. The release bolt and bearings should be cleaned and greased with oil regularly.
Recommended air pressure
The wheelchair is delivered as standard with solid wheels. Find where the size is given on the driving
wheel/castor wheel, then find the recommended maximum air pressure in the table. Note that high
air pressure makes the wheelchair easier to roll, whilst lower air pressure gives more cushioning. For
optimum handling properties, the air pressure should be checked regularly.

Inspection after six months, subsequently every year
• Check that the brake works properly. Adjust if necessary.
• Check that the tyres are whole and that there is no damage to the sidewalls.
• Ensure that the wheelchair is clean and that all moveable parts work.
• Check for slack on the front castor wheel fork. Adjust if necessary. The axle should run freely
around its axis, but there should not be any slack in an up/down direction.
• Check screwed joints and adjust where necessary.
