Caution: After replacing the brushes, run the wheelchair gently for the first few
miles to allow the brushes to seat properly.
Check bearings
The Everest Lite has bearings only in the caster wheels, not in the drive wheels. Always
be alert for unusual noises in the bearings or excessive caster wobble. These signs
indicate that the bearings are becoming worn and may require replacement. The caster
bearings should be inspected every six months and replaced as needed. This should be
performed by a Graham-Field Health Products dealer.
