User manual CATERPILLAR CM845 BROCHURE

[. . . ] The CM845 screed offers variable frequency tamper bars, vibratory screed plates, double-width extenders, LCD operating display, and electric heat for high performance on all types of mix designs and job sites including interstates, highways, airports. [. . . ] The double-width extenders maximize job site versatility by delivering a wide paving range to meet application requirements. An intuitive LCD display keeps the operator informed of screed plate temperature, tamper bar speed, vibratory speed, and screed counter-balance pressure. The easy-to-use electric screed heat system quickly gets the plates and tamper bars up to the ideal operating temperature for fast starts. The CANbus electrical system, color-coded and numbered electrical wiring, sealed and soldered connections, and O-ring face seal fittings ensure top performance and long term reliability.
