NOTE: Never run the engines that have air filters without them. Rapid engine wear can result. 1. Press the tab on the air filter cover and lift the cover, or un-thread the thumbscrews, depending on the model of engine you have. See "Figure 6-5". Figure 6-5 2. Replace paper element when dirty or damaged. Clean foam element or replace when damaged. 3. To clean foam element, separate it from the paper element and wash in liquid detergent and water. Allow to dry thoroughly before using. Do not oil the foam element. Adjustments DO NOT make any engine adjustments. Factory settings are satisfactory for most conditions. If adjustments are needed, contact your Authorized MTD Servicing Dealer. Carburetor If you think you carburetor needs adjusting, see your nearest Authorized MTD Servicing Dealer. Engine performance should NOT be affected at altitudes up to 7,000 feet (2,134 meters). For operation at higher elevations, contact your Authorized MTD Servicing Dealer. Alternator (if equipped) Contact your Authorized MTD Servicing Dealer for alternator related electrical problems such as: • Inoperative Starter • Discharged Battery • Fuse Replacement • Alternator Maintenance/Repairs Engine Speed WARNING! To avoid serious injury or death, DO NOT modify engine in any way. Tampering with the governor setting can lead to a runaway engine and cause it to operate at unsafe speeds. NEVER tamper with the factory setting of the engine governor. WARNING! Running the engine faster than the speed set at the factory can be dangerous and will VOID THE ENGINE WARRANTY. Removing Snow from the Engine After each use, remove snow from the following areas: • Oil Fill Cap Dipstick • Fuel Fill Cap • Recoil Starter/Flywheel Screen • Linkage • Guards • Spark Plug Connection (if visible). • Electric Starter Switch Box, if present (see the equipment Operator's Manual instructions). NOTE: See the equipment Operator's Manual instructions for proper location of fuel fill cap and control lever. 1. Removing snow will ease operation of the recoil starter rope and reduce the risk of water contamination when opening the fuel fill cap. NOTE: For more information about recoil starters, see Engine's with Recoil Starters in the Operation Section of this manual. Transporting Your Engine WARNING! NEVER transport this engine inside of another vehicle or in any enclosed space if there is any gasoline in the tank. Fuel vapor or spilled fuel may ignite. WARNING! If there is fuel in the fuel tank, close the fuel valve, if equipped, and transport the engine upright in an open vehicle, such as an open trailer or open bed of a pickup truck. If you DO NOT have an open vehicle and have to transport the engine upright in a closed vehicle, follow these steps for emptying the fuel tank before transporting: 1. Empty fuel tank by using a commercially available suction device designed for use with gasoline. WARNING! DO NOT pour fuel from the engine or siphon fuel by mouth. 2. Drain fuel into an approved red gasoline container, being careful to avoid spilling. 3. Run the engine until remaining fuel is consumed. WARNING! NEVER leave the engine unattended when it is running and NEVER run the engine in an enclosed area. Storing Your Engine Short-Term/Seasonal Storage Clean Engine If the engine has been running, allow it to cool for at least half an hour before cleaning. Before servicing the engine, remove the carburetor cover and/or blower housing. Discard the dirt and debris from the following areas: • Cooling Fins • Air Intake Screen or Recoil Starter/ Flywheel Guard Areas • Spark Plug Connection • Levers • Linkage Area • Guards • Carburetor • Head Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire. NOTE: Do not spray engine with water to clean because water could contaminate fuel. Using a garden hose or pressure washing equipment can also force water into the air cleaner or muffler opening. Water in the air cleaner will soak the paper element, and water that passes through the element or muffler can enter the cylinder, causing damage. WARNING! Accumulation of debris around muffler could cause a fire. Inspect and clean before every use. Section 6 - Maintenance 13
