WARNING WORK AREA SAFETY • Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit. Cluttered, wet, or dark work areas can result in injury. Using the engine in confined work areas may put you dangerously close to other cutting tools and rotating parts. • Do not allow the engine to come into contact with an electrical source. The engine is not insulated and contact will cause electrical shock.
and perform its intended function. Replace damaged or worn parts immediately. Never operate the engine with a damaged part. Specific Operation Warnings WARNING Gasoline and its vapors are extremely flammable and explosive. Fire or an explosion can cause severe burns or death. When Adding Fuel • Turn engine 'off' and let it cool at least 2 minutes before removing the fuel filler cap. • Fill the fuel tank outdoors or in a well-ventilated area. • Do not overfill the fuel tank.
WARNING • Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result. • When starting engine, pull cord slowly until resistance is felt, then pull rapidly. • Direct coupled equipment components such as, but not limited to, blades, impellers, pulleys, sprockets, etc., must be securely attached. WARNING • Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories.

Before Each Use ⚠WARNING Improperly maintaining this engine, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously hurt or killed. Always perform a pre-operation inspection before each operation, and correct any problem. Pre-Operation Checks For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the engine to check its condition.
Operating Instructions ⚠WARNING • Gasoline and its vapors are extremely flammable and explosive. • Fire or explosion can cause severe burns or death. • Engines give off carbon monoxide, an odorless colorless, poison gas. Breathing carbon monoxide can cause nausea, fainting or death. • Unintentional sparking can result in fire or electric shock. • Unintentional start-up can result in entanglement, traumatic amputation, or laceration.
2. To start a cold engine, move the choke lever to the CHOKE position. To restart a warm engine, leave the choke lever in the RUN position. 3. Move the throttle lever away from the MIN. position, about 1/3 of the way toward the MAX. position.
4. Turn the engine switch to the ON position. 5. Operate the starter. Recoil Start Pull the starter grip lightly until you feel resistance, then pull briskly in the direction of the arrow as shown below. Return the starter grip gently. ⚠WARNING Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter. Electric Starter Turn the key to the START position, and hold it there until the engine starts.
When the engine starts, release the key, allowing it to return to the ON position. ⚠WARNING Using the electric starter for more than 5 seconds at a time will overheat the starter motor and can damage it. 6. If the choke lever has been moved to the CHOKE position to start the engine, gradually move it to the RUN position as the engine warms up. Stopping the Engine To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal conditions, use the following procedure.
1. Move the throttle lever to the MIN. position. Some engine applications use a remote-mounted throttle control rather than the engine-mounted throttle lever shown here. 2. Turn the engine switch to the OFF position. 3. Turn the fuel shut-off to the OFF position.
Setting Engine Speed Position the throttle lever for the desired engine speed. Some engine applications use a remotemounted throttle control rather than the engine-mounted throttle lever shown here. Refer to the instructions provided by the equipment manufacturer. For engine speed recommendations, refer to the instructions provided with the equipment powered by this engine. Maintenance ⚠WARNING All the components used to build this engine must remain in place for proper operation.
○(1) Clean ○(1) Air Cleaner ○ Replace Sediment Cup Clean ○ Check-adjust ○ Spark Plug ○ Replace ○ Spark Arrester Clean Idle Speed Check-adjust ○(2) Valve Clearance Check-adjust ○(2) Combustion Chamber Clean Fuel Tank & Filter Clean Fuel Tube Check After every 500 Hrs.(2) ○(2) Every 2 years (Replace if necessary) (2) Note: (1) Service more frequently when used in dusty areas.
Before Adding or Checking Oil • • Place engine on a level surface. Clean the oil fill area for any debris. How to Check/Add Oil ⚠WARNING Gasoline is highly flammable and explosive. You can be burned or seriously injured when refueling. • Stop engine and keep heat, sparks, and flames away. • Refuel only outdoors. • Wipe up spills immediately. 1. Remove the oil dipstick and wipe with a clean cloth. 2. Insert the oil dipstick into the filler neck without screwing it in. 3.
You may use unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume. In addition, methanol must contain co solvents and corrosion inhibitors. Use of fuels with content of ethanol or methanol greater than shown above may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of the fuel system.
Carburetor Adjustment Never make adjustments to the carburetor. The carburetor was set at the factory to operate efficiently under most conditions. However, if adjustments are required, see any our Authorized Dealer for service. ⚠CAUTION The manufacturer of the equipment on which this engine is installed specifies the top speed at which the engine will be operated. Do not exceed this speed. How to Replace the Spark Plug If the engine has been running, let it cool before servicing the spark plug.
Inspect Muffler and Spark Arrester ⚠WARNING Running engines produce heat. Engine parts, especially muffler, become extremely hot. Severe thermal burns can occur on contact. Combustible debris, such as leaves, grass, brush, etc. can catch fire. 1. Allow muffler, engine cylinder, and fins to cool before touching. 2. Remove accumulated debris from muffler area and cylinder area. 3. Replacement parts must be the same and installed in the same position as the original parts or fire could result.
How to Service the Air Filter (figure 1) 1. Remove the air cleaner outside cover (A). Be careful to prevent dirt and debris from falling into the air cleaner assembly. 2. Separate the Air Filter (A) from the Air Filter Housing (B). 3. Inspect the air filter. Clean dirty air filter with warm water and mild soap. Allow air filter to dry thoroughly before re-installation 4. Install the air filter assembly onto the carburetor and secure with screw.
Removing Oil The oil must be drained from the Oil Drain Plug (figure 2). 1. 2. 3. 4. Remove the dipstick (C) Please an approved container below the oil drain plug. Remove the Oil drain plug (D) and allow oil to the drain into the approved container. Install Oil drain plug (D) and wrench tighten. How to Service the Fuse-(figure 3, if applicable) ⚠WARNING Never use a fuse with a rating greater than the one originally equipped with the engine. Serious damage to the electrical system or a fire could result.
How to Service the Battery (figure 4, if applicable) ⚠WARNING Be careful not to connect the battery in reverse polarity, as this will short circuit the battery charging system. Note: Use a 12-volt battery with an ampere-hour rating of at least 18 Ah. 1. Connect the positive (+) cable to the starter solenoid terminal. 2. Connect the negative (-) cable to an engine mounting bolt or other good engine ground connection. 3. Connect the positive (+) cable to the positive (+) terminal. 4.
The following precautions should be taken if storing your engine for a period exceeding 30 days, or for seasonal storage. • • • • • • While engine is still warm, change oil. Clean engine of surface debris, chaff or grass. Drain all fuel from fuel tank into proper receptacle for storage. Remove spark plug. Place 1 teaspoon or 5 ml. of oil into spark plug hole. Pull starter rope slowly 8-10 times to properly coat the cylinder bore and piston for storage. Replace spark plug and tighten.
