MAINTENANCE
WARNING: Maintenance and repairs must
be done by authorized person-
nel only. Keep all fasteners tight.
Use only genuine Clarke parts.
WARNING: Do not operate this machine un-
less it is completely assembled.
NOTE: For maintenance of the floor tools read the
manual given with the tools.
After Each Use of the Machine
1. Remove unused cleaning solution from the solu-
tion tank, by placing the end of the vacuum hose
in the solution tank. Start the vacuum motor.
Stop the motor when the tank is empty.
2. To prevent damage to the valves and jets, flush
one gallon of clean water through the solution
system and the tools.
3. Disconnect the power cord from the outlet.
4. For optimum performance, flush the machine with
clear water at the end of each working day. Once
a month, minimum, run a flushing compound
through the machine to cut any alkaline build-up
that may have formed.
5. Lubricate wheels, casters, and hinges as needed.
The pump and vacuum motor do not require any
maintenance.
6. The body can be cleaned with a general all-
purpose detergent and protected with a silicone
type product. The quick-disconnects should be
lubricated with silicone, also.
7. Prior to each job, inspect the holding tank filter
and the recovery tank float filter for hair and dirt.
The drain valve should also be inspected regularly
and kept free of any debris or build-up.
8. Drain the recovery tank and dispose of properly.
9. Rinse the recovery tank with clean water.
10. Use a dry cloth to wipe the tools and both tanks,
inside and out.
11. Apply a small amount of silicone lubricant to the
quick-disconnect fittings. To prevent damage to
the O-rings, do not use an oil lubricant.
