Idle Speed
1. Perform “Preparation”. (Refer to page Bl-8.)
2. Apply parking brake.
3. Check that the idle speed is within specification.
Idle speed (Neutral or P range): 750 f 50 rpm
Caution
l Check the idle speed without the electric cooling
fan operating.
Note
l When the parking brake is not applied, the idle
speed for ATX model (Canada) is approx. 800 rpm.
4. If not within the specification, adjust the idle by turning the
air adjusting screw.
5. Disconnect the
SST.
