Illustration 1 g02134117Retarder control lever (1) is located to the right side of the steering column. The retarder control has four positions:DISENGAGED position - When the lever is in position (A), the hydraulic retarder will disengage.FIRST STAGE position - Move the lever to position (B) to provide minimum engagement of the hydraulic retarder.SECOND STAGE position - Move the lever to position (C) to provide medium engagement of the hydraulic retarder.THIRD STAGE position - Move the lever to position (D) to provide maximum engagement of the hydraulic retarder.The transmission hydraulic retarder will engage automatically when the accelerator control is in the LOW IDLE position and the retarder control is in any of the following positions:
FIRST STAGE position
SECOND STAGE position
THIRD STAGE positionThe traction control system is automatic and does not require any input from the operator for proper machine operation in the various ground conditions that may be encountered during operation.Monitor the transmission oil temperature while the retarder is engaged. Overheating of the transmission oil can result from extended use of the retarder. If the transmission oil overheats during retarding, use the service brakes to downshift to a lower gear.The retarder is less effective after an upshift and is more effective after a downshift. To prevent an upshift, increase the amount of retarder engagement. If the retarder is already on the third stage of engagement, then use the service brakes to slow the machine to downshift to a lower gear. Avoid using the service brakes to maintain current gear.As the retarder control lever is moved from first stage through second stage to third stage, the level of hydraulic retarding is progressively increased. Use the hydraulic retarder in the second and third stages when the machine is fully loaded and the machine is operated on steep grades.When service brakes are applied during downhill grade operation or at high speed on flat ground, the hydraulic retarder may automatically engage or increase level based on amount of service brake application being used. This is to prevent service brake wear and overheating. Operator should use retarder control in the third stage or slow the machine to speed appropriate for desired hydraulic retarder stage. Hydraulic retarder will engage to desired retarder control stage until service brake application is used. Light service brake application at slower speeds may not cause an increase in hydraulic retarder.The hydraulic retarder may be automatically disabled on flat ground once the machine slows down and the transmission is in second gear or less. This automatic disablement occurs when the retarder control is in the first, second, or third stage position.
