corrections to be performed by Operator maintenance.
Perform the PMCS procedures listed in Table 1 at the following intervals:
Perform "Before" PMCS just before operating the semitrailer.
Perform "During" PMCS while operating the semitrailer.
Perform "After" PMCS immediately after operating the semitrailer.

After operation in water, mud, or loose sand, clean the semitrailer as soon as possible. Lubricate without
waiting for the next scheduled service.
