4.2 Setting the Tray Tilt Angle
The Model 260200 Rotator has a fixed tray tilt angle of 23 degrees. The Model 260250
Rotator is shipped with the tray support neck set at the maximum tilt angle of 23 degrees.
After the tray has been securely fastened to the neck, the tilt angle can be adjusted by
firmly applying pressure to the high edge of the tray while lifting upward on the low
edge. This should be done with the tray empty. It is advisable to practice this adjustment
several times until the amount of pressure required is apparent.
4.3 Loading the Tray
Insure that the power is off before loading the tray. The Rotators are designed to handle
total loads of up to 1 kilogram. For best results, always evenly distribute the load over
the surface of the tray from the center outward. Do not place objects on the tray, which
are not stable on the mat. Do not place objects on the Rotator, which do not lie stable on
the mat. In general, objects greater than 25mm in diameter are unstable.
4.4 Adjusting the Rotation Speed
Start the Rotator by activating the power switch. On the Model 260250 Rotator, the
speed can be adjusted by turning the Speed Control knob clockwise to increase speed.
For loads approaching 1 kilogram, it may be necessary to first start the rotating motion at
high speed and then back off the speed to the desired lower setting.
4.5 Avoid Overloading
Avoid stalling the Rotator motor through overloading or blocking the rotation of the tray.
Motor life may be affected or motor damage may occur if the motor is repeatedly stalled.
