84 4 DLT ENGINE ANTISTALL SETTING : Speed should increase from idle speed. If not adjust antistall in the direction of throttle travel as required. 5 Move the throttle lever to near full throttle position and release. The die-down time should be maximum 4 seconds without any undershoot (speed reducing below idle speed and jerk / vibration observed). If it is more than 4 seconds move antistall screw in the direction of the drive end as required. If undershoot is observed move in the direction of throttle travel. 6 Verify and confirm that idle speed has not been disturbed. If idling found to be disturbed, repeat the antistall setting procedure (steps 4 to 7). l Don’ts Do not try to adjust / set idle speed with antistall screw. Fig. 168 Drive End Idling Screw Antistall screw Direction of throttle travel Procedure l This is set to prevent vehicle stalling when the accelerator pedal is suddenly released from the depressed position l Setting is achieved by optimizing between dead travel and die-down time. l Verifying / Adjusting Antistall setting 1 Warm the engine sufficiently to ensure that the thermostat is open and the engine is free to rotate. 2 Air-conditioning should be in the off position. No other external loads (like power steering, alternator loads) should be imposed on the engine. 3 Check idling speed. Adjust the same using idling screw to the specified value, if required. (850- 900 rpm). 4 Move the throttle lever by approximately 2.0mm.
