MAINTENANCE & REPAIR
SEMI-ANNUAL CHECKS
1. Check the motor brushes. We recommend that
your authorized dealer inspect the brushes every
six months, or sooner if your power wheelchair is
not operating smoothly. If inspection determines
excessive wear on the brushes, they must be
replaced or motor damage will result.
Warning! Failure to maintain the brushes could
void the power wheelchair’s warranty.
To inspect or replace the motor brushes:
1. Unscrew the motor brush caps (Fig. 18).
2. Remove the brushes.
3. Inspect the brushes for wear (Fig. 19).
4. Replace the brushes if necessary.
2. Inspect the state of the battery terminals every six
months. Make sure that they are not corroded and
the connections are tight. Periodically apply a thin
film of petroleum jelly on the surface of terminals to
Guard against corrosion.
PERIODICAL CHECKS
1. Make sure to keep the controller clean while protecting it from rain or water. Never
hose off your power wheelchair or place it in direct contact with water.
2. Keep wheels free from lint, hair, sand and carpet fibers.
3. Visually inspect the tire tread. If less than 1/32", please have your tires replaced by
your local dealer.
4. All upholstery can be washed with warm water and mild soap. Occasionally check
the seat and back for sagging, cuts and tears. Replace if necessary. Do not store
your chair in damp conditions as this will lead to mildew and rapid deterioration of
the upholstery parts.
5. All moving mechanisms will benefit from simple lubrication and inspection.
Lubricate using petroleum jelly or light oil. Do not use too much oil, otherwise small
drips could stain and damage carpets and furnishings etc. Always perform a
general inspection of the tightness of all nuts and bolts.
