Curtis PMC 1204X/1205X/1209/1221 Manual
G. If you have SRO, check it out similarly. Turn off the SRO interlock. Place
the direction switch in forward, turn the interlock back on, and apply the throttle.
The motor should not run. If the motor runs, recheck the wiring. Repeat this test,
selecting reverse before turning on the SRO interlock.
H. Take the vehicle down off the blocks and drive it in a clear area. It should have
smooth acceleration and good top speed.
I.
On vehicles that are intended to plug brake, test the plug braking by driving
forward at moderate speed and shifting into reverse without letting up on the
throttle. The vehicle should smoothly brake to a stop and accelerate in reverse.
J.
On vehicles that are intended to have plug braking inhibited, verify that the
maneuver in "I" produces freewheel coasting.
K. Finally, check your emergency reverse. If your vehicle uses a belly-button
emergency reverse switch to enhance plug braking current, depress the button
while the vehicle is moving forward (toward the operator). The vehicle should
stop quickly (more quickly than in Step "I") and accelerate in reverse at full speed
as long as the belly button is depressed. If the belly button is pushed while the
vehicle is moving backwards (away from the operator), the vehicle will accelerate
to full speed but will not change direction.
