2.2 THROTTLE PEDAL INSPECTION
THROTTLE FREEPLAY
If the throttle pedal has excessive play due to cable
stretch or cable misadjustment, it will cause a delay
in throttle speed. Also, the throttle may not open fully.
If the throttle pedal has no play, the throttle may be
hard to control, and the idle speed may be erratic.
Check the throttle pedal play periodically in
accordance with the Periodic Maintenance Chart
and adjust the play if necessary.

2. Put the gear shift lever in the N(Neutral) position.
