Reason for Machine Operation Check
To ensure that the traction lock valve is operating correctly. Also to check for proper operation of the 2WD/4WD
solenoid valve and proper begin point adjustment on the front motor.
After completion of these checks, operate the machine in a flat, smooth open area. Set the machine for 4WD
operation. Depress the traction lock switch. Drive the machine at full speed. Release the traction lock switch; the
machine should pick up speed. Shift the machine to 2WD and repeat this test. The machine should pick up
speed again. If maximum speeds are in question, check machine speed. Run the machine in 2WD and 4WD
in forward and reverse at maximum RPM for one minute. In 2WD, the machine will go 100 feet in 3.6-4.0
seconds. In 4WD, the machine will go 100 feet in 10.6-11.6 seconds. The machine must be traveling at full speed
at the start of the measured distance.
