and answers with solutions
1.1.1 What are the various actions associated with vehicle maintenance. (p. 8) - ANSWER
inspection, lubrication, adjustment, cleaning, testing, and replacing components that have failed
or are on the verge of failure
1.1.2 Define preventive maintenance (p. 8) - ANSWER Services and/or checks scheduled based
on measurable intervals which are designed to keep vehicles and equipment functioning
properly
.1.3 Define demand or breakdown maintenance. (p. 8) - ANSWER On an unscheduled basis,
which is referred to as demand, or breakdown maintenance.
.1.4 Define motor vehicle maintenance, (p. 9) - ANSWER inspection, lubrication, adjustment,
cleaning, testing, and replacing components that have failed or are on the verge of failure
1.1.5 What impact does lack of maintenance have on the vehicles? (p. 9) - ANSWER If
maintenance is not performed on a periodic basis, the life-span of the vehicles will be reduced,
requiring their replacement or that of their more costly systems/ components at a date earlier
than should be expected.
1.1.6 What impact does lack of maintenance have on the drivers? (p. 9) - ANSWER Employees
using the vehicles will be greatly inconvenienced, their productivity will drop, a work backlog
will invariably develop and the vehicle maintenance personnel may be blamed.

and Mileage
1.2.4 When would fuel consumption be the preferred factor for determining PM interval? (p.
14) - ANSWER In fleets with an extraordinary amount of time idling
1.2.5 Why would fuel consumption be important to PM scheduling? (p.14 - ANSWER Fuel
consumption standards can be utilized for vehicles that incur significant or regular idle time, but
are not equipped with hour meters (most light duty vehicles). Pre-set intervals are an option
where vehicle use is very structured or just the opposite, when use is very sporadic.
