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-quar-
ter 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 cables to battery. (Completely
cover the terminal nut and bolt, cable clip and
any exposed cable with jelly).
4. For Answers To Questions: Contact your supplier.
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.

may cause the 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
