Machine Maintenance
Follow the maintenance schedule to keep the
machine in good working condition.
FOR SAFETY: When servicing the machine, unplug
the power cord(s) from wall outlet(s).
Daily
1. Empty and thoroughly rinse out both the
solution and recovery tanks.
2. Wipe off the power cord(s) and inspect for
damage. Repair or replace as necessary.
3. Coil the cord(s) neatly after use.
4. Clean the exterior of the machine with an all‐
purpose cleaner and a damp cloth. Protect the
exterior with an automobile interior polish.
Weekly (or after approximately 20 hours of use)
1. Flush the solution system with a diluted
descaler to dissolve normal chemical build‐up:
a. Pour 2 gallons of warm water (less than
120 °F/ 49 °C) into the solution tank and
add diluted descaler (dilute according to
mixing instructions on the chemical
package).
b. Turn on the heater (on machines with a
built‐in heater).
c. Turn on the pump and spray through the
cleaning tool for 1 minute.
NOTE: hard water or chemical deposits
that break up during descaling may
become trapped at the spray tips. It is best
to remove the spray tips from the tool and
let them soak in the diluted descaler.
d. Turn off the heater and turn off the pump.
Allow the chemical to sit in the machine for
2 hours.
2. Inspect the vacuum hose for holes and loose
hose cuffs.
3. Inspect the spray pattern for clogged spray
tips. If the tips are clogged, remove them and
soak them in white vinegar for a few hours.
Wash them out, but never push anything into
the orifice in the spray tip to unblock it; the
hole can become enlarged which would
require replacement.
4. Inspect the solution hose and quick
disconnects for leaks or damage. Lubricate the
QDs with an all‐purpose, water‐resistant
lubricant.
5. Lubricate the wheels and casters with an all‐
purpose, water‐resistant oil.
6. Inspect the machine for water leaks and loose
hardware. Repair/replace as necessary.
7. Remove the ball float and clean the screen.
8. Clean the in‐line solution filter (refer to the
exploded view of the machine for the location).
Machine Storage
1. Drain the machine completely of all liquid in
the tanks.
2. Turn the pump on and spray until all the liquid
is pumped out and air is evident.
3. Drain and dry the vacuum hose.
4. Leave the lid off the recovery tank.
5. Store the machine upright in a heated location.
