SAFARI

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).

Don’ts

Do not try to adjust / set idle speed with antistall

screw.

Procedure

This is set to prevent vehicle stalling when the

accelerator pedal is suddenly released from the

depressed position

Setting is achieved by optimizing between dead

travel and die-down time.

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.
