   CAUTION:

   • Wash the equipment and hoses with appropriate detergent before and after measurement.
   • Always perform the inspection after the engine check and adjustment.

   • Do not perform the inspection continuously for 5 seconds or more at stall. (Time from the accelerator full close to full open, stall speed reading and the accelerator full close)
   • After performing the stall test, be sure to cool down the engine for at least 1 minute with the select lever set in P or N position, and at an idle speed of 1200 r/min or less.
   • If the stall speed is higher than the specified range, finish the stall test in as short a time as possible, in order to prevent the automatic transmission from being damaged.
