FILLING OPERATIONS STEP 1 RECOVERY TANK Remove recovery tank SOLUTION TANK STEP 2 FILL LINE Add water 7 gal. (26.5 ltr.) 140°F (60°C) STEP 3 FILLING THE CADET NOTE: Use clean bucket of water to fill solution tank 7 – 14oz. (207ml – 414ml) Add cleaning chemical Do not put defoamer, solvents, spotter or prespray chemicals in the solution tank. Do not allow water to spill into vacuum motor inlet. Dry spillage from top of solution tank before replacing recovery tank.
OPERATIONS STEP 1 Remove electrical cord and literature from recovery tank. Fill solution tank (see filling operations, page3-5). STEP 2 Plug cord into grounded outlet. Note: Be sure dome is seated on recovery tank, and float shut-off is installed correctly. STEP 3 Adjust brush to proper setting. Note: For good operation the brush must skim the carpet. If circuit breaker trips raise brush to prevent damage to motor or carpet. STEP 4 Turn on both Vacuum and Pump motor switches (“ON”=“I”).
OPERATIONS Tip machine back by main handle to move to starting point. STEP 5 Lower machine to floor. STEP 6 Select intermittent or continuous switch setting to turn on brush and start solution spray. The intermittent setting requires the operator to hold the switch in the “on” position with the thumb, and is typically used in small areas where short cleaning passes are made.
CLEANING PROCEDURE 1ft. (30cm) STEP 1 Start at wall closest to power outlet. Pull straight back without pushing down on handle. STEP 2 Release intermittent setting or turn off continuous setting on brush/spray switch approximately 1 foot before ending cleaning pass. STEP 3 Push down on handle to raise vacuum shoe and brush before moving to the next cleaning pass. Overlap brush contact area approximately 1inch. OFF 1in.
CLEANING PROCEDURE Use right side of machine for cleaning against walls. STEP 5 After cleaning, turn off all controls, return brush to storage position and carefully unplug machine. STEP 6 OFF OFF OFF To speed drying, use a Windblower™ fan. STEP 7 Empty recovery tank by releasing dump hose. Use a hose with cold water to clean out the recovery tank. Also drain solution tank after each use.
ACCESSORY TOOL USAGE STEP 1 Use only one of the following acceptable accessory tools. 150-52 Hose Assembly 89226 Wand 380-29 Upholstery Tool 380-21 Crevice Tool 380-36A Auto Detail Tool Pull back collar and insert over machine mounted fitting, then release collar to lock into place. STEP 2 STEP PUMP VACUUM ON 3 Lift door on front of vacuum shoe and insert 1 ½ inch hose cuff into hole. Turn on Pump and Vacuum Switch.
MAINTENANCE SERVICE SCHEDULE MAINTENANCE Check machine for cord damage Check recovery dome and gasket for damage and cleanliness Check brush – should be clean with no lint or strings attached Inspect vac shoe for blockage; remove fibers with coat hanger, etc.
MAINTENANCE PERIODIC MAINTENANCE Twice a month, flush a white vinegar solution (One quart vinegar to two gallons of water) or antibrowning solution (mixed as directed) through the extractor. This will prevent build-up of alkaline residue in the system. If spray jets become clogged, remove the spray tips, wash them thoroughly, and blow-dry. NOTE: Do not use pins, wire, etc. to clean nozzles as this could destroy spray pattern. Periodically inspect all hoses, electrical cables and connections on your machine.
