Failure to comply with these parameters may result in damage to equipment and is
a health hazard to the operator. If the density of the material to be pumped is high,
dilute or mix the material before performing the operation. The operating time must
be such to avoid the pump reaching maximum temperature. A long operation time
without stops may cause, besides excessive heating, damage to vanes, housing and seals.
9.3 STOP
To stop the vacuum pump, stop the motor and disengage the PTO so as to avoid involuntary
operation.
9.4 CONTROL DEVICES
A switch lever is provided as standard to control switching between vacuum and pressure
modes. It is located in the top area of the manifold and can be used manually. To establish in
which direction to turn the lever to select vacuum or pressure, comply with the labels provided
by the truck manufacturer.
NOTE TO MANUFACTURER: Either port can be as suction or discharge. Choose the ports
that are most convenient and label them clearly.
The selection of vacuum or pressure mode by the lever must be carried out with
the vacuum pump stopped.
Two accessories are available for remote control of the switch lever rotation; the first device is a
Pneumatic (air) Actuator (figure 8), when connected to an air compressor, enables switch lever
rotation.
