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 han dle or service batteries.
2. Adding Water: (Wet Cells Only)
• Wet-type lead acid batteries need periodic
replacement of water 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
con necting cable to battery. (Completely cover the
terminal nut and bolt, cable clip and any exposed
cable with jelly).

WARNING
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.
5. Check for signs of wear and correct air pressure in
pneu matic tires weekly.
6. For best performance, inflate tires to the same pressure
level, as shown on the tire sidewall:

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.
