IMPROPER USE WILL VOID THE WARRANTY.
March2007
•Always use a defoamer when foaming occurs to prevent vacuum motor damage.
•Never use water above 130°F (54°C).
•Do not use outdoors or where temperature is below freezing. Protect your machine
from any extremes in temperatures.
•Do not let the pump run dry. Turn the pump off and refill the tank when cleaning solution
gets low.
•Flush the machine with an acid de-scaler regularly (monthly or more often) to prevent
a build-up of minerals or chemicals in the pump and heat systems. Follow the flush
with a clear water rinse to remove any particles and to rinse the acid from the machine.
•Use approved chemicals only.All chemicals should be mixed thoroughly. Liquid
chemicals are recommended to prevent powder buildups.ApH between 6 and 9 is
recommended. The use of high alkaline detergents or strong acids will accelerate the
wear of the pump and seals, and will void the warranty.
•All extension cords must have a rating of at least 12/3 (#12 cord). Extension cords
should be no longer than 50 feet. Replace the plug immediately if the ground prong
becomes damaged or is broken off.

OPERATION
1Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2Fill the Solution Tank with warm water. Using warm water may be a benefit in cleaning
effectiveness, but do not use hot water (above 54 °C/130 °F) in the tank. Add liquid cleaning
solution with a pH value of between 6 and 9. High pH detergents and/or acid rinses will
accelerate the wear of the seals and will void the warranty.
3Plug in the power cord.
4Attach the spray hose to the solution quick disconnect on the front of the machine and attach
the vacuum hose to the hose barb on the recovery tank. Attach the other ends of the hoses to
the cleaningtool.
5Turn the pump on. Turn the vacuum on. NOTE: the pump has a built in pressure switch; the
pump runs only when you are spraying.
6Begin cleaning using the correct hoses and tool.
7Use defoamer in the recovery tank any time foaming occurs.
8Monitor the water level in the solution tank. Do not let the pump run dry.
9When the solution tank gets low, turn off the pump, fill the solution tank, empty and clean the
recovery tank.
10 When finished with the job, remove any unused solution from the solution tank, and run a few
gallons of clean water through the system to rinse out any detergent.
BALL FLOAT VACUUM SHUT-OFF
Prior to using the machine, always check that the float filter is clean and the ball can travel freely.
When the recovery tank is full, the ball float will rise and will shut off the vacuum flow to prevent any
more water from entering the tank. Turn off the vacuum, and empty the recovery tank.
NOTE: if foam is present or if the ball float is prevented from rising, the float will not be able to stop
the air flow, and the tank may over fill.
CAUTION!
To avoid vacuum motor damage, always make sure the float filter is clean and the ball can travel
freely prior to using the machine. And always use a defoamer when foaming occurs.
