PRECAUTIONS
WARNING
After ANY adjustments, repair or service
and BEFORE use, make sure all attach-
ing hardware is tightened securely - oth-
erwise injury or damage may result.
CAUTION
DO NOT overtighten hardware attaching
to the frame. This could cause damage
to the frame tubing.
SUGGESTED MAINTENANCE
PROCEDURES
1. Before using your Tracer Series wheelchair, make sure
all nuts and bolts are tight. Check all parts for damage or
wear and replace. Check all parts for proper adjustment.
WARNING
DO NOT use the wheelchair unless it has
the proper tire pressure (p.s.i.). DO NOT
overinflate the tires. Failure to follow these
suggestions may cause the tire to explode
and cause bodily harm.
2. If tires are pneumatic, recommended tire pressure is
listed on the side wall of the tire.
3. The wheels and tires should be checked periodically
for cracks and wear, and should be replaced when
necessary by your authorized dealer or by a qualified
technician.
4. Periodically check handrims to ensure they are se-
curely attached to the rear wheels. Refer to REPLAC-
ING REAR WHEEL HANDRIM in PROCEDURE 4
of this manual.
5. Periodically adjust wheel locks in correlation to tire
wear. Refer to WHEEL LOCK ADJUSTMENT in
PROCEDURE 7 of this manual.
6. Periodically check front caster and rear wheel hubs
to make sure they are clean.
