1.7.5 Effects of incorrect adjustments

Table 1.31 lists a selection of possible incorrect adjustments, together with their
effects on the operation of the vehicle. This is intended to be an exercise to help
you see why correct adjustments are so important; not so you know how to do it
wrong! You must also be able to make a record and tell a customer the effects,
if you are unable to make the correct adjustments. This could be due to some
parts being worn so that adjustment is not possible.

Remember though, anyone can mess with a vehicle and get it wrong. As a
professional you will get it right, the customer and your company will be happy
and it will affect your pay rates in years to come.

1.7.6 Maintenance and inspections

The purpose of routine maintenance is simple; it is to keep the vehicle in good
working order and in a safe condition. Manufacturers specify intervals and
set tasks that should be carried out at these times ( Fig. 1.100 ). It is usually a
condition of the warranty that a vehicle should be serviced according to the
manufacturer’s needs. The main purpose of regular inspection, therefore, is to
check for the following:
● malfunction of systems and components
damage and corrosion to structural and support regions
●
leaks
●
water ingress
●
component and system wear and security.
●
Inspections are usually:
aural – listening for problems
●
visual – looking for problems
●
functional – checking that things work.
