TEST NOTES
1. Stop watch should be started with the function, not
with the controller or switch.
2. All speed tests are run from ground with remote con-
trol connected on the basket.
3. Function speeds may vary due to cold, thick hydrau-
lic oil. Test should be run with the oil temperature
above 100° F (38° C).
