DRIVER

WARNING

Wheel hubs may be hot after operation. Use

care to prevent injury.

a. Check for overheated wheel hubs (1). Immedi-

ately after operation, feel all wheel hubs cau-

tiously for noticeable variation in temperature

between components. An overheated hub indi-

cates a maladjusted, inadequately lubricated, or

damaged bearing.

b. Feel the lower end of the shock absorbers (2)

cautiously and check for variation of tempera-

ture between hull area and shock absorber. If

shock absorber is operating properly, it should

be warmer than the hull area around the shock

absorber. If the shock is cold or overheating oc-

curs, notify unit maintenance.
