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" pneumatic casters - 30 to 40 psi
•10" 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" 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.

D. BATTERY MAINTENANCE
1. To prevent an acid spill, always keep batteries upright (wet cell batteries).
2. Never smoke or hold an open flame near batteries.
3. Always wear rubber gloves and safety glasses when you handle batteries.
1. Maintenance Schedule:
This varies for different types of batteries. Always follow the instructions supplied with
your batteries.
NOTE– Always wear rubber gloves and safety glasses when you handle
or service batteries.
2. Adding Water: (Wet Cells Only)
• Wet-type lead acid batteries need periodic replacement of water lost due to
evaporation.
NOTE– use distilled water only.
• Check the battery fluid level about once a week. When you remove the stoppers
(on top of the battery) there should be one-eighth to one-quarter of an inch of
fluid above the internal plates. Do not overfill.
3. Corrosion:
Check battery terminals often for corrosion.
a. If corrosion is present, use a wire brush to clean the terminals.
NOTE– Always wear safety glasses and rubber gloves.
b. Use baking soda to neutralize acid.
c. Use petroleum jelly to re-grease the terminals after connecting cable to battery.
(Completely cover the terminal nut and bolt, cable clip and any exposed cable
with jelly).
