MAINTENANCE Air Filter Maintenance If the engine seems weak or runs unevenly, the air filter may be clogged. If running with a dirty air filter, the spark plugs can become fouled. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval). WARNING! The engine and the exhaust system become very hot during operation. Risk for burns if touched. Allow engine and exhaust system to cool at least two (2) minutes. IMPORTANT INFORMATION Do not use compressed air to clean the air filter. Do not wash the paper filter. Do not oil the paper filter. Do not tap filter to clean this could cause damage to the sealing. Replacing Air Filter The engine is equipped with a replaceable, high density paper air cleaner element and an oiled, foam precleaner which surrounds the paper element. Check the air cleaner daily or before starting the engine. Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged components. Replace all bent or damaged air cleaner components. IMPORTANT INFORMATION Operating the engine with loose or damaged air cleaner components could allow unfiltered air into the engine causing premature wear and failure. Servicing Precleaner Wash and re-oil the precleaner every 25 hours of operation (more often under extremely dusty or dirty conditions). Replace the precleaner annually, or every 100 hours. 1. Open the door on the blower housing to access the air cleaner element and precleaner. 2. Unhook the latch and remove the precleaner from the air cleaner element, or remove as an assembly for servicing. Make sure the base and the sealing area is clean before reassembly is performed. 3. Wash the precleaner in warm water with detergent. Rinse the precleaner thoroughly until all traces of detergent are eliminated. Squeeze out excess water (do not wring). Allow the precleaner to air dry. 4. Saturate the precleaner with new engine oil. Squeeze out all excess oil. 5. Reinstall the precleaner over the paper element and secure with the latch. 6. Close and latch the door. Servicing Paper Element Check the paper element every 50 hours of operation, (more often under extremely dusty or dirty conditions). Clean or replace the element as necessary. Replace the air cleaner element annually, or every 100 hours. 1. Open the door on the blower housing to access the air cleaner element. 2. Unhook the latch and remove the air cleaner element and precleaner (if equipped). 3. Remove the precleaner (if so equipped) from the paper element. Service the precleaner as described in Precleaner Service. 4. Gently tap the paper element to dislodge dirt. Do not wash the paper element or use pressurized air, as this will damage the element. Replace a dirty, bent, or damaged element with a new one. Handle the new element carefully; do not use if the sealing surfaces are bent or damaged. 5. Clean the air cleaner base as required and check condition. 6. Reinstall the precleaner (if equipped) over the paper air cleaner element and install on the base. Secure with the latch. 7. Close and latch the door. English-41
