D.BATTERY MAINTENANCE
WARNING
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.
Q-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 due to evaporation.
Q-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 inter-
nal 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.
Q-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 connect-
ing cable 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
WARNING
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 pneumat-
ic tires weekly.
2. For best performance, inflate tires to the same pressure
level, as shown on the tire sidewall:
•
14" 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
WARNING
Residual air pressure in tires can cause severe injury.
Make sure you release all air in tire before attempting
to service or repair tires.
Charge Batteries
Check tires for proper inflation level
Check batteries for proper electrolyte
level (wet only)
Check plugs and connectors for
proper connections
Check all moving parts for wear
Inspect all nuts, bolts and fasteners
for looseness or wear
Inspect upholstery for wear
