THEORY OF OPERATION - CONTINUED
Air Cleaner. The air cleaner is a dual-element, dry-type filter. Outside air is drawn through the filter elements by a vac-
uum created in the turbocharger. When one or both of the elements get clogged, a high vacuum switch in the air cleaner
housing turns on the PLUGGED AIR FILTER indicator on the instrument panel.
Muffler and Exhaust Pipe. These components reduce engine noise and carry
exhaust gases away from the engine com-
Steering Wheel and Column. The steering wheel and column are adjustable to eight different positions. Seven of the
positions are for operator comfort, while the eighth and most forward position is for storing and locking the wheel when
not in use. Pushing the wheel into the stored position also moves the transmission control lever to NEUTRAL.
Supplemental Steering. The supplemental steering system has two purposes. It provides an oil supply for the steering
system if the primary system fails or if the engine stops when the machine is moving. It also adds oil to the primary oil
flow when the engine RPM is less than 1,170 and the machine is moving.
Flow Switch. This switch warns the operator of a primary pump or line failure.
