MAINTENANCE AND SERVICING
Measure tire pressure annually with a gauge. Caster tire pressure should be 10 psi (69 kPa).
To maintain pressure, visually check daily that tires h ave not lost pressure, and adjust pressure as needed.
Under-inflation of tires can cause side wall cracks.
NOTE:
If caster wheels shimmy, a possible cause is over-inflation.
NOTE:
An anti-shimmy dampener kit is available for rear caster wheels. Refer to 7.1.2 Anti-Shimmy Shocks for Casters,
page 337 for information.
