1. Check for signs of wear and correct
air pressure in pneumatic tires weekly.
2. For best performance, inflate tires to
the same pressure level, as shown on
the tire sidewall:
• 8" and 9" pneumatic casters -
30 to 40 psi
• 20" pneumatic drive wheels -
35 to 45 psi
3. Caution:
To prevent tire damage:
• Use a hand pump (or a low
volume
air pump) to inflate tires.
• Use a tire gauge to check pressure.
F. TO REPAIR OR REPLACE A TIRE
Residual air pressure in tires can cause severe
injury. Make sure you release all air in tire
before attempting to service or repair tires.
1. 8" or 9" Caster Wheels:
a. Release all air from tire.
b. Remove caster wheel from fork.
c. Make sure there is no residual air in
tire before you remove bolts that hold
the two rim halves together.
d. Remove four bolts from rim. Separate
two halves of rim.
e. Repair or replace inner tube.
f. Reassemble the caster wheel; make
sure the bearing spacer is in place and
all four bolts are secure.
Note:
Use a torque setting of 240 inch-
pounds when tightening bolts.
g. Mount caster wheel onto fork.
Replace washers correctly.
h. Inflate tire to proper pressure level.

E. PNEUMATIC TIRES
1. Do not use this chair if any of the tires are under- or over-inflated.
2. Low pressure in a tire may cause the chair to veer to one side and result in loss
of control.
3. An over-inflated tire may burst.
4. Never use a gas station pump to inflate a tire. Such pumps provide air at height
volume, and cause tire to burst.
