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.
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).

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
• 12" pneumatic drive wheels - 35 to
45 psi
3. Caution:
To prevent tire damage:
• Use a hand pump (or a
low vol-
ume
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 attempt-
ing 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.
