Vacuum Motor Current Draw Test
WARNING: This procedure must be performed by qualied personnel only.
1. Disconnect the vacuum hose to the squeegee.
2. Remove the vacuum grid with the oat, after the test reinstall it.
3. If present, drain the recovery tank, then lift it.

8. Activate the vacuum and check that the current draw of the vacuum motor is between 11 and 12 at 24V.
Stop the vacuum.
Remove the amp clamp (A).
If the amperage is higher, perform the following procedures to detect and correct the abnormal
amperage:
◦ Remove the vacuum system motor (see the “Container and vacuum motor disassembly/assembly”
paragraph), and check the condition of all its components.
If the above-mentioned procedures do not produce the correct readings for the vacuum system motor
amperage, the motor must be replaced (see the “Container and vacuum motor disassembly/assembly”
