CONTROLS

All controls on the Ultra-Vac® are located on the
rear of the machine. Review this section
carefully to familiarize yourself with the function
and movement of each control before starting.
1. Airlock Control:
The right valve controls the operation of
the airlock. Pull on the control to operate
the airlock in the forward direction and
push to operate in the reverse direction.
Stop the airlock by placing the lever in the
center neutral position.
Do not operate for long periods of time in the
reverse direction. The rotor is not designed to
operate in the reverse direction. Reverse
rotation may be used to free jammed object
in rotor only.
Watch and count the arrow revolutions on
the airlock indicator wheel to determine
airlock speed and direction.
2. Boom Rotation Control:
This spring-loaded-to-neutral-centre lever
controls the direction of the boom rotation.
Push on the lever and hold to swing the boom
to the right. (clockwise) Release to return to
centered position to stop rotation. Pull and
hold to swing to the left. (counter-clockwise)
3. Boom Lift Control:
The valve controls the boom position. Push
on the lever to raise the boom and pull to
lower. Place in the center position for no
boom movement.
IMPORTANT
Do not attempt to raise boom while airlock
is in operation.
4. Boom Lock Valve:
This valve is located in the boom lift circuit to
control the oil flowing through the lines. Move
the lever parallel to the line to open the valve
when positioning the boom. Move at right
angles to the line to stop oil flow and maintain
boom position.
Fig. 4-2 Controls
5. Flow Divider:
A flow divider in the airlock circuit is used to
control the airlock speed. Normal operation
should start at a setting of 5. Move in small
increments toward 0 to decrease the speed.
Move toward 10 to increase the speed. Watch
and count the arrow revolutions on the airlock
wheel to determine the speed.
Use Table 1 as a guide to setting the airlock
speed.
Experiment a little to determine the
best setting.
