activates operation of the rocker. Operation will continue until time
has expired or the timer is turned back (counterclockwise) to the zero
position.
T o operate in continuous mode, turn speed dial to the desired setting.
Turn the timer knob left (counterclockwise) to the hold position. This
will begin operation of the rocker. Operation will continue until the
timer knob is turned back (clockwise) to toe zero position.
Note: The timer ma y be stiff and offer some resistance when turned.
This is normal.

the speed dial to the zero position. When the speed dial is turned to
the zero position, the timer will continue to count down.
Note: To avoid splashing of samples, the rocker should be started

2. Locate the access panel on the back of the unit and remove
the 2 screws holding the panel in place.
3. Position a 7/16 inch wrench or adjustable wrench on the nut
holding the bottom connecting rod to the disk. Use the wrench
to turn the disk until the locking hole in the motor shaft collar is
aligned with the access hole on the rear panel. The locking
hole is located 180º from the collar’s set scre w .
4. Insert the locking rod through the access hole and into the
locking hole of the motor shaft collar. This will prevent the
disk from turning while loosening or tightening the nut holding
the bottom connecting rod in place.
5. Loosen the 7/16 inch nut just enough to allow movement of
the nut and connecting rod in the slot. Move the nut outward
from the center of the disk to increase tilt action. Move the nut
inward toward the center of the disk to decrease tilt action.
