•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 cables 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-inflated 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:

•7" pneumatic casters - 30 to 40 psi

•14" 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.
