If it becomes necessary to store in temperatures that 
could drop below 40°F, the pumping system, hoses  
and valves must be protected from freezing with a 
methyl hydrate window washer antifreeze solution. 
 
NOTE: Do not use ethylene glycol or cooling system 
antifreezes. 
 
1.  Add one gallon of window washer antifreeze to 
     the supply tank. 
 
2.  Turn on pump switch and spray until the 
 

anti-freeze solution fills the solution lines. 

 
3.  Drain the leftover antifreeze from the supply tank.  

Always allow the unit to reach room temperature 
before filling with hot water or operating. 

 
4.  Before operation be sure to flush system 
 

completely.  Failure to do so after winterizing 

 

machine will damage carpet. 

 

 

Before making any 
adjustments or repairs to 

the machine, disconnect the power cord from the 
electrical source.  
 
1.  Empty unused cleaning solution from the 
 solution 

tank. 

 
2.  Inspect and clean filter at solution tank fill port 

and at the vacuum intake port in the dome. 

 
3.  Flush pumping system with 1 to 2 gallons of 
 

clean, hot water. 

 
4.  Check spray jet for full spray pattern. 
 
5.  Empty the recovery tank and rinse with clean 

water. 

 
6.  Check for and remove any lint or debris around 

brush and vac shoe. 

 
7.  Clean float screen and check float valve to make 

sure it moves freely. 

 

 
1.  After every 25 hours of operation, flush a white 
 

vinegar solution (ONE quart vinegar to two 

 

gallons of water) or anti-browning solution (mixed 

 

as directed) through the extractor.  This will 

 

prevent build-up of alkaline residue in the system. 

 
2.  If the spray jet becomes clogged, check for debris 

and clean surface of jet. 

 
NOTE: Do not use pins, wire, etc. to clean spray jet 
nozzle as this will deform the jet and destroy the 
spray pattern. 
 
3.  Periodically inspect all hoses, electrical cables,  

filters, gaskets and connections on your machine.  
Frayed or cracked hoses should be repaired or 
replaced to eliminate vacuum or solution 
pressure loss. 

 
4.  The electrical cable must be well insulated, if the  
 

cable insulation is broken or frayed, repair or 

 

replace it immediately.  Don't take chances with  

 

electrical fire or shock. 

 
5.  The filter in the bottom of the solution tank and at 

the fill port must be clean to allow free flow of 
cleaning solution. The screen filter on the vacuum 
intake in the dome must be free of lint buildup to 
ensure full vacuum strength. 

 
6.  The dome gasket must be properly seated and 
 

free of damage to create the air seal needed to  

     extract water.
