Test Notes
1. Personality settings can be adjusted anywhere within
the adjustment range in order to achieve optimum
machine performance
2. Stop watch should start when the function is acti-
vated.Not with the controller or switch.
3. Unless noted, function speeds should be measured from
platform.
4. Platform speed knob must be at full speed (fully clock-
wise).
5. All test should be done with the oil temp above 100° F
(38° C).
