Discard used element and replace with a new one at least once a year. Cleaning the element: The left hand side panel must be removed to obtain access to the air cleaner housing. To clean the element, remove the wing nut and air cleaner cover (see Figure 33 ). Remove the element from the backplate. Take care to avoid dis -lodging accumulated dust on the element into the carburetor inlet. Tap the element lightly on a flat sur -face for cleaning. Do not wash or use solvents to clean elements. Replacing the element: If the perforated metal sleeve is dented or the sealing surface damaged, discard and install a new element. When replacing an element, always examine the air cleaner backplate and be sure it is securely tightened to the carburetor. Install a new backplate if the old one is bent or cracked. Be sure the element fits around the ledge on the backplate before installing air cleaner cover. Replace the cover (rubber gasket must be in place) and tighten the wing nut securely. Do not use pliers, finger tight is adequate. Reinstall the side panel. Properly cleaned and installed air cleaner elements are the best guarantee to continued long and satisfac -tory engine life. 1. Wing Nut 2. Air Cleaner Cover CLEANING ENGINE This tractor has an air-cooled engine. Air must be able to circulate freely around the engine, through the screen, shroud, and over the fins of the cylinder head and cylinder block. Keep these areas free of accumu -lated dirt and trash or engine will overheat and result in damaged moving parts. Periodically clean the inside of the side panels and grille for adequate cooling. ■^note This machine is designed to cool properly with the engine side panels in place. Operating the machine without panels in place may re -suit in inadequate cooling. SPARK PLUGS A WARNING To avoid possible injury, be sure engine is off and cool before making any adjustment or repairs. 22 A NOTE Remove all dirt from around the spark plugs before removing. To remove spark plugs, always use a spark plug wrench. Check gap after every 100 hours of opera -tion. Replace a defective plug with a new plug. Set gap at .025 inch. (See Figure 34.) Tighten plug to 22 ft-lbs. See your authorized dealer for the correct replace -ment plug. Figure 34 1. Spark Plug CLEANING OF CYLINDER HEADS Cleaning of the cylinder heads should only be done by your authorized Cub Cadet Dealer. This process is to be done to keep your engine properly cooled and at its peak efficiency. The frequency of cleaning is dependent upon the type of fuel used. When leaded fuel is used the cleaning interval is 250 hours, and with unleaded fuel the cleaning interval is 500 hours. LIGHTS The headlights are sealed-beam units. Refer to "SPECIFICATIONS" when replacement is necessary. To replace the taillight lamp, remove socket and bulb from the back of the taillight by rotating socket 1/4 turn. Refer to "SPECIFICATIONS". FUSE Always use the same capacity fuse for replacement. Refer to "SPECIFICATIONS." If electrical system mal -functions, check the fuse. To install a new fuse, press in on the fuse housing cap and turn counterclockwise to remove it from the fuse housing. Remove the old fuse and replace with a new one. Then reassemble the cap to the housing. BATTERY INFORMATION A WARNING A. Battery acid must be handled with great care as contact with it can burn and blister the skin. It is also advisable to wear protective clothing (goggles, rubber gloves and apron) when working with it.* B. Should battery acid accidentally splatter into the eyes or onto the face, rinse the affected area immediately with clean cold water. If there is any further discomfort, seek prompt medical attention. C. If acid spills on clothing, first dilute it with clean water, then neutralize with a solution of am -monia/water or baking soda/water. D. Since battery acid is corrosive, do not pour it into any sink or drain. Before discarding emp -ty electrolyte containers, rinse them with a neutralizing solution. E. NEVER connect or disconnect charger clips to battery while charger is turned on as it can cause sparks. F. Keep all lighted materials (cigarettes, matches, lighters) away from the battery as the hydrogen gas generated during charging can be combustible. G. As a further precaution, only charge the battery in a well-ventilated area. ‘Always shield eyes and protect skin and clothing when working near batteries. A DANGER BATTERIES CONTAIN SULFURIC ACID AND MAY CONTAIN EXPLOSIVE GASES (when electrolyte has been added). KEEP BATTERIES OUT OF THE REACH OF CHILDREN. 23 MAINTENANCE OF BATTERY COMMON CAUSES FOR BATTERY FAILURE 1. Check electrolyte level periodically (at least every two weeks). Keep the level to the split rings. Use only distilled water or a good quality drinking water. Never add acid or any other chemicals to the battery after initial activation. 2. The battery should be checked with a hydrometer after every 25 hours of operation. If the...
