7.0 TESTING FOR GROUND CONTINUITY
WARNING:
Test the electrical continuity of the vacuum cleaner before each use.
This will ensure that any static electricity that is produced while
vacuuming will be discharged to ground.
WARNING:
Use only original replacement parts from the manufacturer or from one
of its authorized distributors.
An ohm-meter is required to perform the following electrical continuity test.
a. Disconnect the power cable from the outlet.
b. Make sure that all the latches on the vacuum cleaner are fastened and that the detachable
recovery tank is properly installed on the vacuum cleaner.
c. Disconnect the suction hose from the vacuum cleaner.
d. Using an ohm-meter, test the electrical continuity of the vacuum cleaner from the ground
pin at the end of the power cable to the suction intake of the vacuum cleaner. A reading
between 10
6
ohms and 10
9
ohms or less is satisfactory to ensure proper grounding and
static dissipation.
e. Using the ohm-meter test for the electrical continuity of the suction hose from one end to
the other. A reading between 10
6
ohms and 10
9
ohms or less is satisfactory to ensure
proper grounding and static dissipation.
