4.6 Adjusting the Pressure Continued
The maximum pressure setting is 1200 PSI. However, the highest pressure attained is
dependent on the amount of water flow at the tool:
• Smaller jets and lower flow will allow for higher pressure at the tool.
• Larger jets and higher flow will lower the maximum pressure attained at the tool.
The desired setting will depend on the type of cleaning
and tool used. For example:
• Carpet Cleaning with 2-Jet Wand: 400 PSI
• Tile Cleaning with Hard Surface Tool: 1000 PSI
If adjusting or maintaining pressure becomes a problem,
refer to the “Trouble Shooting Guide” section or contact
your distributor for advice or assistance.
To increase solution pressure, turn
the regulator knob clockwise.
To decrease solution pressure,
turn the regulator knob counter-
clockwise.

6.12 WD-40 Vacuum Motors
Should moisture ever enter the vacuum motors,
completely drain the recovery tank, open the
recovery tank lid, remove the vac shut-off
assembly, turn on both vacuum motors and
spray a five (5) second burst of WD-40 into the
standpipe. Continue to run the vacuum motors
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.
7.0 Storage and Freeze Protection
You must winterize your Hard Surface Extractor to protect the pump system from
freezing and also damage being caused to fittings and valves. Damage due to freezing
is not covered under the Warranty. Store your extractor in temperatures over 40 degrees
Fahrenheit. If you plan on storing your extractor in freezing conditions or for a long
period of time, the following procedure should help prevent your Hard Surface Extractor
from freezing and prevent pump and seals from drying out.
Connect auto-fill water supply hose to machine and faucet.
Vacuum water out of solution tank. Drain water from recovery tank.
