Operation Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating, check the fuel and oil level, and remove debris from the machine. Also, ensure that the area is clear of people and debris. You should also know and have marked the locations of all utility lines. Before you Start g015174 Figure 6 1. Choke 2. Fuel valve • Dig away the earth and remove any stones near 3.
Adding Fuel WARNING Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Avoid prolonged breathing of vapors. • Keep your face away from the nozzle and fuel tank opening. • Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.
Filling the Fuel Tank Starting the Engine 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and allow the engine to cool. 3. Clean around the fuel-tank cap and remove it (Figure 8). 1. Move the fuel valve to the OPEN position, all the way to the right (Figure 9). g015174 Figure 9 1. Choke lever 2.

Grinding a Stump DANGER This machine is capable of amputating hands and feet. • Always wear substantial, slip-resistant footwear. • Stay in the operating position while the machine is running, and keep away from moving parts. • Keep all bystanders a safe distance away from the machine. • Stop the machine immediately if any people or animals enter the work area. g024063 WARNING Figure 10 Grinding a stump throws wood chips, soil, and other debris into the air, which could injure you or bystanders. 1.
each sweep, until you have removed the front portion of the stump to ground level (A through D in Figure 11). 7. Raise the cutting wheel, release the parking brake, and move the machine forward a few centimeters (inches). Engage the parking brake. 8. Repeat steps 5 and 7 until you have completely removed the stump (E through H in Figure 11). 9. Move throttle to the DISENGAGE position, push the handle down enough to raise the cutting wheel off the ground.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important: You can tip the machine backward or on its side to clean or service it, but no longer than 2 minutes. If you hold the machine this position for too long, fuel can drain into the crankcase and damage the engine. Should this happen, perform an extra oil change on the engine. Then turn the engine over a few revolutions with the starter handle before starting the engine again.
Engine Maintenance 8. Secure the cyclone housing using the 3 screws. Servicing the Air-Cleaner Elements Servicing the Air Cleaner Service Interval: Before each use or daily—Check the air filter Removing the Foam and Paper Elements Every 50 hours—Service the air filter Every 600 hours/Every 2 years (whichever comes first)—Replace the air filter. The cyclone air filter collects the largest contaminant particles, which collect in the container.
Servicing the Engine Oil Servicing the Foam Air-Cleaner Element 1. Wash the foam element using a mild detergent and water. 2. Squeeze it dry with a clean cloth. 3. Soak it with new engine oil. 4. Gently squeeze out excess oil from the element in an absorbent cloth. Service Interval: Before each use or daily—Check the engine-oil level. After the first 20 hours—Change the engine oil. Every 100 hours—Change the engine oil. Yearly or before storage—Change the engine oil.
Changing the Engine Oil 1. Start the engine and let it run for 5 minutes. Note: This warms the oil so that it drains better. g205123 2. Park the machine on a level surface and engage the parking brake. 3. Shut off the engine and wait for all moving parts to stop. 4. Change the oil as shown in (Figure 18). g206641 g031623 Figure 18 5.
Removing the Spark Plug 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine, wait for all moving parts to stop, and allow the engine to cool. 3. Locate and remove the spark plug (Figure 20). g205129 g206640 g027478 Figure 19 6. Figure 20 Dispose of the used oil at a recycling center. Checking the Spark Plug Servicing the Spark Plug Important: Do not clean the spark plug(s).
Installing the Spark Plug Fuel System Maintenance Cleaning the Sediment Cup Service Interval: Every 100 hours Yearly or before storage Underneath the fuel valve is a sediment cup to catch dirt in the fuel. g028109 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and wait for all moving parts to stop. 3. Move the fuel valve to the OFF position, all the way to the left. 4. Unscrew the sediment cup (Figure 23). Figure 22 g241891 Figure 23 1.
Brake Maintenance Cooling System Maintenance Adjusting the Parking Cleaning the Engine Screen Brake Service Interval: Before each use or daily Before each use, remove any buildup of grass, dirt, or other debris from the engine screen. This helps ensure adequate cooling and correct engine speed and reduces the possibility of overheating and mechanical damage to the engine. 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and wait for all moving parts to stop.
Belt Maintenance Adjusting the Drive-Belt Tension Service Interval: Before each use or daily Note: Inspect the drive belt through the slot on top of the belt cover. Adjust as required. 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and wait for all moving parts to stop. 3. Loosen the 2 bolts securing the belt guard to machine until you can remove the belt guard (Figure 25). g242386 Figure 26 1. Bolt 6. Loosen the belt-tension bolt and jam nut.
Replacing the Drive Belt Service Interval: Every 100 hours Note: Replace the belt if it shows any signs of wear, cracks, glazing, or damage. 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and wait for all moving parts to stop. 3. Loosen the bolts securing the belt guard to machine until you can remove the belt guard. 4. Remove the belt guard (Figure 25). 5.
Grinder Maintenance Replacing the Teeth Service Interval: Before each use or daily—Check the condition of the teeth; rotate or replace any that are worn or damaged and torque the nuts for all teeth. Due to the high amount of wear placed on the teeth, you need to rotate and replace them periodically (Figure 29). Before you rotate or replace them, inspect each tooth holder on the wheel, including the flat lands that prevent the teeth from rotating. If the tooth holder is damaged, replace the wheel.
Cleaning Removing Debris from the Machine Regular cleaning and washing increases the life span of the machine. Clean the machine directly after use, before the dirt hardens. Before cleaning, check that the fuel-tank cap is properly in place to avoid getting water in the tank. Use care when using a high-pressure sprayer, because it can damage warning decals, instruction signs, and the engine Important: Lubricate the cutting wheel bearings after cleaning.
Storage 17. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer. For storage over 30 days, prepare the machine as follows: 18. Store the machine in a clean, dry garage or storage area. 19. Cover the machine to protect it and keep it clean. 1. Remove dirt and grime from the external parts of the entire unit, especially the engine. Clean dirt and sawdust chips from the outside of the engine cylinder head fins and blower housing.
Troubleshooting Problem The engine does not start. Possible Cause Corrective Action 1. The safety bail is in the OFF position. 1. Hold the safety bail against the handle. 2. If your model is equipped with an engine with an On/Off switch, the switch is in the OFF position. 3. The fuel-shutoff valve is closed. 4. The choke is open. 2. Move the switch to the ON position. 5. The fuel tank is empty. 6. The spark plug wire is loose or disconnected. 3. Open the fuel-shutoff valve. 4.
