TROUBLESHOOTING INSTRUCTIONS
This section is designed to instruct your personnel in methods of troubleshooting on the
Tornado FK 3000. Common maintenance-related issues are noted below, followed by a full
Troubleshooting Chart.
Vacuum System - Poor Suction
During machine operation, if the vacuum
motor is running but the solution is not being
picked up, do the following:
1. With the vacuum motor on, place your
hand over the vacuum hose intake. If
suction is strong, a blockage is in the
squeegee throat.
Clear this blockage by pushing a
screwdriver, or any similar tool,
downward through the top of the
squeegee throat.
2. Check for a loose intake hose
connection, creating an air leak.
3. Check for a clogged mesh intake screen on the standpipe inside the Recovery Tank.
4. Check to see that the ball closure is in place on the end of the Recovery Tank drain
hose.
5. Check to see that the Recovery Tank Cover disk is seated properly on its gasket.
6. Check to see that the liquid shutoff unit is properly seated at rear of recovery tank.
Since the entire Recovery Tank is placed under vacuum by the Vacuum Motor, each fitting and
other entry point should be examined for potential air leakage or blockage.
NOTE: Performing these maintenance procedures will avoid problems with the recovery system
requiring outside repair service. Always be very sure the vacuum system is clear of any
blockage before calling for service.
Vacuum System - Vacuum Motor Inoperative
1. The Recovery Tank is full. When the Recovery Tank is full, the Liquid Shutoff closes and
stops the Vacuum Motor to prevent water from entering it.
2. If the Recovery Tank is not full, use the Troubleshooting Chart to diagnose problems with
the shutoff switch, motor, connectors, etc.
