Test Notes
1. Stop watch should be started with the function move-
ment, not with actuation of joystick and switch.
2. Drive speeds should be set to the values below regard-
less of the tire size.
3. All speed tests are run from the platform. These speeds
do not reflect the ground control operation.
4. The platform speed knob control must be at full speed
(turned clockwise completely).
5. Some flow control functions may not work with the Plat-
form Speed Control knob clicked into the creep posi-
tion.
6. Functional speeds may vary due to cold, thick hydraulic
oil. Test should be run with the oil temperature above
100° F (38° C).
