Common problems and Troubleshooting:
No water or insufficient water from the brush
1. Check whether the water volume control handle has been opened sufficiently
2. Check whether the drain switch is closed?
(check whether the water discharge indicator is on? The indicator light of the water drain switch will
only be on when the machine is running under the working state of the brush. If it is not on, check
whether the water drain switch is turned off by operation?)
3. Confirm that there is still water in the solution tank
(check the water level pipe of the solution tank. If no water can be seen at the water level pipe,
even if there is a small amount of water, it will affect the outlet water.)
4. Check whether the filter screen is blocked?
(remove the filter cover, check whether the filter screen is blocked and clean the filter, observe
whether the water outlet of the filter inlet is normal? If the water outlet is not normal, please check
whether there is foreign matter blocking in the solution tank. filter screen must be installed, If there
is no filter screen, the solenoid valve or other pipelines will be damaged.)
Routine inspection can't be ruled out, then we need to ask professional maintenance
personnel.
When the machine pass through, it will leave a silk like trace after squeegee.
There are sand grains, hair or small sundries on the ground, which will affect the scraping of the
rubber, leaving a filiform trace.
Resolvent:
1. The cleaning efficiency can be greatly improved by using the sequence of pre sweeping and
then cleaning.
2. Adopt the backward reoperation method, so that the sundries under the rubber can separate
from the rubber and resume normal operation.
3. Repeat the cleaning with the methods of initial cleaning and fine cleaning.
Large area is not clean after machine operation
1. The scraping is good in the middle and bad on both sides of
the squeegee.
2. The scraping on both sides of the squeegee is OK, but the
scraping in the middle is not good.
3. one side good, one side bad.
