Use and Care Manual

RETURNING THE C-4 TO RENTABLE CONDITION AFTER EACH USE.
1) Examine the power cord, plug and switches for damage or wear. Wipe down power cord. (Note: Damaged or worn
electrical components must be replaced.)
2) Turn on the vacuum motor, let it run to blow out any trapped water. (Note: Unusual motor noise indicates motor
needs replacing.)
3) Pull spray/brush switch to activate pump and brush. Make sure both are working properly. (Note: Pump should not
be run dry more than a few seconds, it becomes loud when dry.)
4) Drain all unused solution from the solution tank by lowering the drain hose.
5) Remove bucket and spray it inside and out with cleaning disinfectant. Let sit.
6) Wipe debris from lid filter screen. (Located on the underside of lid.)

8) Spray the outside of the machine with cleaning disinfectant. (Note: Do not spray air vents on the back door, control
panel on the handle or any electrical components.)
9) Tilt machine forward. Remove hair and debris from brush. Clean vacuum nozzle with lint hook. Ensure wheels are
clean.
10) Turn the brush by hand to ensure it turns freely. (Note: If brush does not turn freely, remove brush and clean
between brush and bearings. Also inspect bearings.) See Servicing and Rebuilding Brush Assembly.
11) Wipe machine and rinse bucket. (Note: Do not spray the air vents on the back door, control panel on the handle
or any electrical components.)
12) Using shop towels and disinfectant, wipe down the entire machine and hoses.
13) Keep the bucket ventilated between rents by laying the bucket handle underneath the lid to prevent the lid from

SERVICE WARNINGS
Warning: Only genuine Kent Investment Corp. electrical replacement parts should be used. Failure to do
so will void the UL and CSA electrical safety compliance and could result in fire, electrical shock, personal
injury or damage to the model C-4.
Warning: 1. Do not tilt machine all the way back to floor with water in bucket. Water will go through lid,
down to vacuum motor and may damage the vacuum motor.
2. If this happens return unit upright and place towel under exhaust port. Turn on the Suction Switch, run
until no water discharges out of exhaust port, about 2 to 3 minutes.
Warning: Pump should not run dry for more than a few seconds. Running the pump dry may cause the
pump to overheat.
