S. The Next Generation Modular Cooling EPA Tier 3/EU Stage IIIa compliant and System with Air-to-Air Aftercooling with MEUI, an air-to-air aftercooler, System has been added to the 990H to axle-shaft brakes, impeller clutch torque help meet emissions requirements and converter and planetary electronic power improve efficiency, serviceability, shift transmission forms a responsive, visibility and sound levels. [. . . ] Transmission shifting for forward, neutral, reverse is controlled by the operator's fingers and gear selection is controlled by the operator's thumb. These factors combine to produce a fluid motion that reduces effort and allows the operator to work the machine for long periods of time with little or no fatigue. Operates the impeller clutch torque converter for approximately the first inch of travel, then engages the brakes. With air suspension and retractable seat belt, including (4) trainer seat and lapbelt, are designed for comfort and support. Seat cushions reduce pressure on the lower back and thighs while allowing unrestricted arm and leg movement. The retractable seat belt stays off the floor and is easy to reach. Are attached to the right side of the seat.

Continually monitors various machine systems through three instrument clusters and provides a three-level warning system to alert the operator of immediate or pending problems. EMS III shares information with the engine, hydraulic and transmission controls that can be used during servicing to simplify service and troubleshooting. Detects and warns the operator of extreme axle cooling oil temperature through indicator light. Allows the operator to preset the engine speed for a variety of applications. Turns the Rimpull Control System on and off. 11 Optional Payload Control System II. Offers on-the-go weighing to assist in loading trucks more accurately. It also has easy computer download capability. Is used by the operator to keep track of Payload Control System II information. Is used in roading, load and carry and other applications where load retention, spillage and operator ride may be a problem. It provides lift arm suspension system by placing an accumulator in the lift arm circuit. Allows quicker cycle times by shifting from 1st forward to 2nd reverse. Feature pilot-operated lift and tilt circuits with a two lever controller that is floor-mounted and adjustable. Has four positions: raise, hold, lower and float. It can adjust the automatic kickout from horizontal to full lift. [. . . ] Other special tires are available on request.
