7 Introduction
Propulsion System/
Transmission
The propulsion system is a hydrostatic system
with a hydraulic pump supplying two motors
connected in parallel. The motors drive the front
and rear drums.
The speed of the machine is proportional to the
deflection/angle of the control lever from neutral.
Brake system
The brake system consists of a service brake,
secondary brake and parking brake. The service
brake is hydrostatic and is activated by moving the
control lever to neutral.
Secondary/Parking Brake
The secondary and parking brake system
consists of spring multiple disc brakes in the
motors. The brakes are released with hydraulic
pressure and are operated with a switch on the
instrument panel.
Steering System
The steering system is a hydrostatic system.The
control valve on the steering column distributes
the flow to the control cylinder, which actuates the
articulation.
The steering angle is proportional to the deflection
of the steering wheel.
FOPS and ROPS
FOPS is the abbreviation for Falling Object
Protective Structure (roof protection) and ROPS is
the abbreviation for Roll Over Protective
Structure. If any part of the FOPS/ROPS
structure'sprotective construction displays plastic
deformation or cracks, the FOPS/ROPS structure
mustbe replaced immediately. Never perform
unauthorized modifications on the FOPS/
ROPSstructure.
Roller Applications
The CC 1250 roller is built in accordance with
international standards and recognized safety
rules. Nevertheless, misuse may constitute a risk
to the life and limb of the user or third parties, and
may cause damage to the roller or other material
property.
The CC 1250 roller must be used in accordance
with its designated use as described in this
manual. The roller must only be operated by
trained, safety-conscious persons who are fully
aware of risks involved in operating the roller. Any
functional disorders, especially those affecting the
safety of the roller, must be corrected
immediately.
Designated Applications
The CC 1250 roller is designed primarily for
compaction of asphalt. It has excellent
compaction capacity for reinforcement layers and
bearing courses.The roller is mainly intended for
compacting asphalt on streets and minor roads in
towns. It has sufficient capacity to follow a small
asphalt paver.
Non-Designated Applications
The CC 1250 roller is not designed to use as a
ladder, support, or a work surface. it is not used to
carry or transport passengers or equipment. The
manufacturer/supplier cannot be held liable for
any damage resulting from such use. The risk of
such use lies entirely with the user.
Operating the CC 1250 roller within the limits of its
designated use also involves compliance with the
inspection and maintenance directives contained
in the operating manual.
