SEMI-ANNUAL CHECKS
1. Check the motor brushes. We recommended that your authorized dealer inspect the
bushes 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 warranty.
To inspect or replace the motor brushes:
1.Unscrew the motor brush caps. (See Figure 27)
2.Remove the brushes.
3.Inspect the brushes for wear (See Figure 28)
4.Replace the brushes if necessary.

1. 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 mechanism 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.
