Maintenance; Troubleshooting Guide - Jon-Don PE500 Safety, Operation And Maintenance Manual With Parts List

5.0 Maintenance

WARNING: Disconnect electrical power cord before performing any service or
maintenance inside the machine base or before testing or repairing switches or power
cords. Failure to do so may result in severe personal injury or death.
Regular maintenance is required to keep your Carpet Extractor in proper working
condition. Failure to properly maintain your machine could void warranty. Thoroughly
clean all equipment and accessories after each use:
• Rinse the solution and recovery tanks with clean water.
• Flush the pump system with clean water, including all hoses and wands.
• Do not allow water to remain in the tanks after use.
• Lubricate all quick disconnects with WD-40 or similar lubricant.
• Clean vacuum float assembly screen.

5.1 Clean Vacuum Float Assembly Screen
Inside the recovery tank, on top of the stand pipe, is
the vacuum float assembly. It functions to prevent
debris and water from being sucked into the vacuum
motors. Operating the equipment without the float
assembly or with a poorly maintained assembly will
greatly decrease the life of the vacuum motor and
will VOID your warranty.
If debris builds up on this filter, it will reduce
the vacuum airflow and may cause a significant
decrease in the rate of water recovery. If debris
prevents the float ball from moving or seating inside
the assembly, it may not stop the airflow when the tank fills with water and water will be
sucked in the vacuum and blow out the exhaust.
To clean, twist off the float assembly from the stand pipe and clean the screen. Pull fibers
and lint off and rinse with clean water. Push the assembly back onto the stand pipe and
replace the recovery tank lid.
This screen should be cleaned daily, especially if the carpet extractor is being operated in
an environment which has an abnormal buildup of lint and debris, such as cleaning newly
installed carpet. Loss of vacuum is most normally associated with lint buildup in this
filter at the top of the vacuum stand pipe.
