Insufficient Water Pick-up
Good water pick up performance depends on the proper amount of air owing through the squeegee pickup
tool. Air entering the vacuum system before the pickup tool will reduce its ability to pick up water. Anything
that restricts the movement of air through the system will also reduce its ability to pick up water.
Possible Causes:
• Damaged squeegees
• Restricted air ow
– Clogged or kinked squeegee vacuum hose
– Clogged vacuum motor inlet or outlet port
• Air leaks
– Recovery tank lid gasket is not sealing
– Cracked squeegee vacuum hose
– Cracked recovery tank
• Vacuum motor is weak
Troubleshooting Steps
Begin with a good visual inspection of the system. Check the condition of the squeegees and the recovery
hose. Take the recovery hose off and rinse it out. Check the recover tank cover gasket condition. Repair any
problems found.
If no visual problems are found, test the system using a vacuum gauge PN 56205281 and open- hole adapter.
(See the Special Tools Section below. The adapter can be made from a piece of PVC pipe.)
1. Remove the vacuum hose from the squeegee tool.
2. Hold the vacuum gauge against the end of the hose and turn
on the vacuum motor. Note the reading on the gauge. If it is
within 10% of specs, go to the next step. If it is too low, check
for air leaks in the system.
