Daily Pretrip Inspection and
Maintenance
Complete the following inspection and maintenance
procedures to ensure that vehicle components are in
good working condition before each trip. A driver who
is familiar with the vehicle and drives it regularly can
perform the daily inspections, then add the weekly
and monthly post-trip inspections as scheduled.
If the driver does not operate the vehicle on a con-
sistent basis, all daily, weekly, and monthly inspec-
tion and maintenance procedures should be per-
formed before the trip.
IMPORTANT: The pre- and post-trip checklists,
inspections, and maintenance procedures de-
tailed in this chapter are not all-inclusive.
Refer to other component and body manufactur-
ers’ instructions for specific inspection and
maintenance instructions, as well as local, state,
and federal guidelines.
NOTE: If any system or component does not
pass this inspection, it must be corrected before
operating the vehicle. Whenever equipment re-
quires adjustment, replacement, and/or repair,
see the Cascadia Workshop Manual for proce-
dures and specifications.erticfied
