| veer to one side and result in loss of control. |
| 3. An |
| 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" & 9" (200 & 250mm) pneumatic casters– 30 to 40 psi (207 to 275 kpa)
•12" (310 mm) 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
Residual air pressure in tires can cause severe injury. Make sure you release all air in tire before attempting to service or repair tires.
