Description
Category I (urban transport) applies to vehicles that
annually travel
up to
20,000 miles (32 000 kilome-
ters).
Category II (rural transport) applies to vehicles that
annually travel
over
20,000 miles (32 000 kilome-
ters).
The table under
Vehicle Maintenance Schedule Table
shows the two categories of vehicle usage. For each
category, the appropriate distance and time intervals
are given for performing Initial Maintenance and for
repeating each maintenance operation set (M1
through M3).
The table under
Maintenance Interval Table
shows
which maintenance operation set must be performed
at the actual distances (miles and kilometers) or ac-
tual months of operation for each maintenance cat-
egory. The schedule of actual distances (and
months) is based on the intervals given in the Ve-
hicle Maintenance Schedule Table.
The table under
Maintenance Operation Sets
lists, in
numerical order, the text reference numbers and de-
scriptions of
all
maintenance operations, and indi-
cates all maintenance operation sets at which each
operation must be performed.
Each
Maintenance Interval Operations
table (IM
through M3) lists the appropriate text reference num-
bers and descriptions of only those maintenance op-
erations that must be performed at that maintenance
operation set. Each maintenance operation set is
listed in a separate Maintenance Interval Operations
table.
Use
Before placing your new vehicle in service, determine
the maintenance category (Category I or II) that ap-
plies to your intended use of the vehicle. See the
Vehicle Maintenance Schedule Table to determine
the distance (or time) interval at which each mainte-
nance operation set must be performed for your cat-
egory of vehicle.
When the vehicle reaches the actual distance (or
months) given for an interval, see the Maintenance
Interval Table to find the maintenance operation set
that applies to that interval. Then perform the mainte-
nance operations listed in the applicable Mainte-
nance Interval Operations table. Use the mainte-
nance operation reference numbers to find
instructions in the manual for completion of each op-
eration.
Complete each maintenance operation set at the re-
quired interval. Then, when you have completed
maintenance operation set M3 under the 12th Main-
tenance Number listed in the Maintenance Interval
Table, repeat the pattern. The 13th Maintenance
Number will begin at maintenance operation set M1,
under the 1st Maintenance Number listed in the
Maintenance Interval Table.
NOTE: When performing operations for the 13th
Maintenance Number, complete the M1 opera-
tions only, not the Initial Maintenance opera-
tions.
To determine the distance/months for the 13th Main-
tenance Number, add your category’s
distance/months for the 1st Maintenance Number to
the distance/months for the 12th Maintenance Num-
ber, then perform the operations listed in the appli-
cable table in the Maintenance Interval Operations
tables. For the 14th Maintenance Number, add the
distance/months for the 2nd to the distance/months
for the 12th; continue this pattern for each succes-
sive Maintenance Number.
