speed specified in the GENERAL SPECIFICATIONS sec-
tion.
Determine the speed by measuring the time it takes to
travel a known set distance with the vehicle at maximum
speed.
Enter the time and distance into this formula to calculate
speed:
•
Rate (in MPH) = (Distance in feet ÷ 5280) / (Time in
seconds ÷ 3600)
•
Rate (in KPH) = (Distance in meters ÷ 1000) / (Time
in seconds ÷ 3600)
For example:
•
(300 ft. ÷ 5280) / (13.6 sec. ÷ 3600) = 15 MPH
•
(100 m ÷ 1000) / (15 sec. ÷ 3600) = 24 KPH
If the speed is not within the specified speed range, stop
the vehicle and adjust the governor compression spring
as described in procedure above.
Tightening the spring results in a speed increase, while
loosening it will result in a speed decrease.
Repeat the test and adjustment until the factory recom-
mended governed speed is achieved.
Install a new safety seal on the governor after calibrating
the vehicle.
