Operation
The operation section is a reference for the new operator
and a refresher for the experienced operator. This section
includes a discussion of gauges, switches, machine controls,
attachment controls, transportation and towing information.
Photographs and illustrations guide the operator through
correct procedures of checking, starting, operating and
stopping the machine.
Operating techniques outlined in this publication are basic.
Skill and techniques develop as the operator gains knowledge
of the machine and its capabilities.
Maintenance
The maintenance section is a guide to equipment care.
The Maintenance Interval Schedule lists the items to be
maintained at a specific service interval. The Maintenance
Interval Schedule lists the page number for the step-by-
step instructions required to accomplish the scheduled
maintenance procedure.
Maintenance Intervals
Use the service hour meter to determine servicing intervals.
Calendar intervals shown (daily, weekly, monthly, etc.) can be
used instead of service hour meter intervals if they provide
more convenient servicing schedules and approximate the
indicated service hour meter reading. Recommended service
should always be performed at the interval that occurs first.
Under extremely severe, dusty or wet operating conditions,
more frequent lubrication than is specified in the maintenance
intervals chart might be necessary.
Perform service on items at multiples of the original
requirement. For example, at every 100 service hours, also
service those items listed under every 50 service hours and
every 10 service hours or daily.
A Description of the Machine
The C120R is an evolution of Rayco’s purpose-built mulcher
line. With features such as a 121hp diesel engine, large
cab with side-entry door, impressive mulcher lift height. The
C120R is ideal for those who want a powerful mulcher in a
compact chassis. The C120R has an overall width of just
83-inches, and weighs in at 15,900lbs including the mulcher
making it easy to transport and nimble enough for operation
on jobs where larger mulchers just don’t work.
The C120R rides on rubber tracks with 2-speed travel. The
rubber track design promotes longer track life and smooth
operation by reducing debris packing in the track chain and
keeps the drive components out of the hi-impact areas.
Powerful final drives provide torque for climbing hills and allow
the C120R to maneuver easily in difficult terrain.
Because it’s purpose-built, the C120R is loaded with features
operators appreciate. The spacious cab is equipped with
a heated, air-ride suspension seat, and the rear fan is auto-
reversing, reducing maintenance time. All gauges and
controls are located on a large LCD display that includes
a rearview camera.
