Air filter

Environmental conditions have an important effect on the frequency at which the air filter needs service.
Certain air filters have a separate dust bowl (A1) which must be cleaned at intervals. The amount of dust in the
bowl shows if it has been removed at the correct time for the conditions of operation. Do not let dust completely
fill the bowl, because this will reduce the life of the filter element (A2).
Certain air filters have automatic dust valves (B1) through which dust is expelled from the filter. The rubber
dust valve must be kept clean. Ensure that the sides of the valves close completely together and that they can
separate freely.
If a restriction indicator is fitted, see "Restriction indicator" on page 37, it will indicate precisely when the air
filter element needs service. This prevents the premature removal of the filter element which causes extra cost
or late removal of the element which can cause loss of engine power.
The filter element must be cleaned or renewed according to the manufacturer's recommendations.
