Milton CAT M322D - Manual (Page 12)

Ground Level Maintenance. Caterpillar
designed its D-Series Wheel Excavators
with the operator and service technician
in mind. Gull-wing doors, with
pneumatically-assisted lift cylinders,
effortlessly lift up to allow critical
maintenance to be performed quickly
and efficiently while maintaining
operator safety.
Extended Service Intervals.
The D-Series Wheel Excavator service
and maintenance intervals have been
extended to reduce machine service
time, increase machine availability and
reduce operating costs. Using S•O•S
SM
Scheduled Oil Sampling analysis,
hydraulic oil change intervals can be
extended up to 4,000 hours. Engine
coolant change intervals are 12,000 hours
with Cat Extended Life Coolant.
Self-Monitoring System with Auto-
Diagnostics. The electronic engine and
machine controllers provide detailed
diagnostic capability for the service
technicians. The ability to store active
and intermittent indicators simplifies
problem diagnosis and reduces total
repair time, resulting in improved
machine availability and lower
operating cost.
Engine Inspection. The engine can be
accessed from both ground level and the
upper structure. The longitudinal layout
ensures that all daily inspection items
can be accessed from ground level.
Front Compartment. The front
compartment hood can be opened
vertically, providing outstanding ground
level access to the batteries, air-to-air
after cooler, air conditioner condenser
and the air cleaner filter.
Easy to Clean Coolers. Flat fins on all
coolers reduce clogging, making it
easier to remove debris. The main
cooling fan and air conditioner condenser
are both hinged for easier cleaning.
Swing-out Air Conditioner Condenser.
The Air Conditioning condenser swings
out horizontally to allow complete
cleaning on both sides as well as excellent
access to the air-to-air after cooler.
Air Filter. Caterpillar air filters eliminate
the use of service tools, reducing
maintenance time. The air filter features
a double-element construction with wall
flow filtration in the main element and
built-in mini-cyclone precleaners for
superior cleaning efficiency. The air
filters are constantly monitored for
optimum performance. If airflow
becomes restricted, a warning is displayed
by the way of the in-cab monitor.
