WARNING! • If an extension cord is used, the plug and socket must be of watertight construction. • Inadequate extension cords can be dangerous. • Extension cords must be 12/3 and no longer than 50 feet. Replace the cord or unplug immediately if the ground prong becomes damaged.
KNOW YOUR SWITCH PLATE Solution Pump Switch - This switch turns the solution pump ON and OFF. Vacuum Switch - This switch turns the first of the two vacuum motors ON and OFF. Vacuum Switch - This switch turns the second of the two vacuum motors ON and OFF. Circuit Indicator - When this light is on, it indicates that the two cords are on a separate circuit.
PREPARING THE MACHINE FOR USE See the diagrams in the “Know Your Machine” section. Inspect the machine, hoses, and cleaning tools for cleanliness and completeness. Screw the Recovery Tank Lid (11) closed. Ensure the drain cap is closed tightly. Pre-spray spots and heavy traffic areas before extracting with the detergent of your choice. Mix the pre-spray according to the detergent manufacturer’s directions.

CAUTION! Always make sure the float is clean and travels freely before turning on the machine. A float that is stuck will cause the vacuum motor to suck in water, resulting in vac motor damage. The recovery tank has a Recovery Tank Shutoff Float (10) to block the vacuum system when the recovery tank is full. You can tell when the float closes by the sudden change in the sound of the vacuum motor.
• *Check Carbon Brushes • * Have a Hydramaster service technician check the vacuum motor carbon brushes once a year or after 300 operating hours. Check the pump motor carbon brushes every 500 hours or once a year. IMPORTANT! Motor damage resulting from failure to service the carbon brushes is not covered under warranty.
Spraying too long. Try spraying for 12-15 seconds, or about three strokes. • Spray tips(s) too large. Use a maximum of two HydraMaster part number 000-076-122 spray tip(s). LOW HEAT Longer hose or larger diameter hose than recommended. Use a maximum of 25-foot-long ¼ inch hose for best results.
