57.6.4 Air Intake System
IMPORTANT
Do not run engine with air cleaner
disconnected or disassembled.
Engine intake air (A) is drawn through a duct (B)
from the cooling box that pre-cleans the air, then
through a dual element filter (C) to the turbo-
charger intake (D). The charged air then passes
through a cooler and into the engine. The air
cleaner canister is equipped with a vacuator
valve (E) that removes dust continuously from
the air cleaner housing.
57.6.4.1 Restriction Gauge
The air cleaner is also equipped with a
mechanical sensor (F) which indicates red when
the primary filter element requires servicing.
a. Check restriction gauge daily.
b. After servicing, re-set restriction gauge by
pushing button (G) on top of gauge.
NOTE
Only service filter element when restriction
gauge indicates red. Over-servicing the filter
element increases the risk of dirt being ingested
by the engine, and severely damaging the
engine.
