Service Maintenance Checklist
Whenever there is a vacuum problem, it’s best to check over the entire system. Use the checklist below as a guide to
thoroughly check the vacuum system.
□
Inspect and clean the vacuum motor float switch. (If the switch is closed [tipped up] the vacuum motor will not operate)
□
Clean built-up dirt from the inside of the squeegee tool.
□
Replace the squeegee blades if they are nicked or torn.
□
Inspect the hose between the squeegee tool and the recovery tank and rinse any built-up dirt from the hose. Replace the hose if it is kinked or
damaged.
□
Inspect and make sure the gasket on the recovery tank cover is sealing and not damaged.
□
Make sure that the recovery tank drain hose cap seals airtight.
□
Inspect and clean the vacuum motor inlet filter screen.
Troubleshooting Guide
If water flows around the ends of the squeegee tool instead of being pulled into the tool, the vacuum system is not
working correctly. When a vacuum system performs poorly it is usually because of one of the following problems:
Vacuum Leaks
– Air flowing into the vacuum system past a bad gasket or leaky hose, damaged tank or a leaky
drain valve. A vacuum leak below the water line will create turbulence in the recovery tank, causing water to enter
the vacuum motor.
Restrictions
– Anything that blocks the flow of air through the system. Restrictions may also be caused by built-up
debris in the squeegee tool, vacuum hoses or vacuum motor inlet screen, or wherever the airflow is forced to make a
sharp turn.
Both leaks and restrictions decrease the quantity of air flowing through the squeegee tool. The air that does go
through the squeegee tool moves slower, so it has less suction (water lift performance).
