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 high volume, and
may cause tire to burst.
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" & 9" (200 & 250mm) pneumatic casters–
30 to 40 psi (207 to 275 kpa)
•12" (310 mm) pneumatic drive wheels–
35 to 45 psi (240 to 310 kpa)
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" & 9" (200 & 250mm) Caster Wheels:
a. Release all air from tire.
b. Remove caster wheel from fork using a 1/2" wrench.
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 using a #3 phillips
screwdriver. 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
tightened to a torque of 60 in.-lbs. (6.8 N.m).
g. Mount caster wheel onto fork. Install washers
correctly tighten bolt to 240 in.-lbs. (27 N.m).
h. Inflate tire to proper pressure level.
