4. Inate tires to pressures stated above. Measure
the circumference of each drive tire. Adjust tire
pressures within the above range to try to make
tire circumferences match as closely as possible.
5. For Serial Nos. 599,999 and Lower: Check the
tire pressure in the pneumatic front caster tires.
Adjust the tire pressure to 16 psi (110 kPa).
Note: Front caster tires have permanent tire
sealant installed.
For Serial Nos. 600,000 and Higher:
Semi-pneumatic caster tires do not need to be
