[. . . ] HU800BBC Operator’s Manual 532 43 85-53 Rev. 2 06. 08. 11 BY Printed in U. S. A. Safe Operation Practices for Walk-Behind Mowers IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS. FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. Look for this symbol to point out important safety precautions. [. . . ] Be sure fuel valve is in the ON position. To start a cold engine, move handle mounted throttle/ choke control lever to CHOKE position. Hold operator presence control bar down to the handle. To start engine, pull starter handle quickly. Slowly move throttle control lever to FAST position after engine starts. • To start a warm engine, move throttle control lever to FAST position, then follow steps above. NOTE: Allow a cold engine to warm up for one minute before starting the blade. See “BLADE CONTROL” in this section of this manual. OFF CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Empty the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. TO STOP ENGINE (See Fig. 13) • To stop engine, move throttle control lever to STOP position. Wait until blade and all moving parts have stopped and turn fuel valve to OFF position if you do not intend to restart the engine soon. CHOKE LEVER FUEL VALVE LEVER ON ( ) OFF ON FIG. 14 9 OPERATION MOWING TIPS CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments are hazardous, will damage your mower and could void your warranty. • Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time. For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly. For better grass bagging and most cutting conditions, the engine speed should be set in the FAST position. When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher. [. . . ] Plastic cannot breathe, which allows condensation to form and will cause your unit to rust.

CAUTION: Never store the lawn mower with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
