5.0 Maintenance Continued
5.4 Clean In-Line Pump Filter
CAUTION: before proceeding with this procedure, make sure
both the power cords are disconnected.
• Unlatch the base of the machine and tip the tanks back.
• Carefully expose the in-line filter in the motor base.
Unscrew the clear H20 cup.
• Remove the screen from the cup. Be careful not to bend the
screen.
• Rinse both the screen and cup with fresh water.
• Reassemble the H20 filter and replace it carefully into the motor base.
• Lift the tanks back onto the base and restore the latch.
IMPORTANT: this filter must be cleaned at least once a week to prevent water blockage
to the pump.
5.5 Clean Dump Valve
The dump valve, located on the back of the machine, has a track inside of it. Open the
dump valve and check the track for build-up. This build-up could prevent the dump valve
from closing and cause leaking. Use a toothbrush to clean the track of the dump valve.
5.6 WD-40 Vacuum Motors
Should moisture ever enter the vacuum motors, completely drain the recovery tank, open
the recovery tank lid, remove the vacuum float assembly, turn on the vacuum motor and
spray a burst of WD-40 into the standpipe. Continue to run the vacuum motor for at least
three (3) minutes.
To prevent moisture from damaging the vacuum motors during storage, empty the
recovery tank and store with the lid open.
5.7 Prevent Mineral Deposit Build-Up
Vinegar may be used to prevent mineral deposit build-up in your machine's lines and
pump. Failure to do so may clog your lines and pump. Every two weeks, pour vinegar
into the solution tank (dilute with 1/2 water). Run the pump, while squeezing your wand
or upholstery tool's trigger unit you smell vinegar or notice it coming out of the tool. Let
the machine sit overnight, and no longer, with the vinegar in its lines. The next day, flush
the machine with 1-gallon of clean water or until you do not smell vinegar any longer.
PLEASE NOTE: If you choose to use CLR, follow the directions on the bottle. DO NOT
leave CLR in the machine's lines and flush thoroughly. CLR may corrode the machine's
components and VOID your warranty. If you choose to use vinegar, you MUST dilute
with 1/2 water. Failure to do so may damage the machine's components and VOID your
warranty.
