Controls Product Overview Become familiar with all the controls (Figure 3 and Figure 6) before you start the engine and operate the machine. Handle-Release Knob The handle on this machine can be folded down for easier transport. 1. Unscrew the handle-release knob from the machine (Figure 4). g025789 Figure 3 1. Handle 2. Throttle lever 8. Recoil-start handle 9. Cutting wheel 3. Handle-release knob 4. Air filter 5. Sediment cup 10. Lift 11. Belt cover 12. Fuel cap 6. Fuel valve 13.
Throttle Lever Choke Lever The throttle lever controls the engine speed. With the lever released, in the DISENGAGED position, the engine runs at idle. This is also the starting position. When you pull the lever to the handle, the engine speed increases, the centrifugal clutch engages, and the cutting wheel rotates. Use the choke lever (Figure 3) to start a cold engine. Before pulling the recoil-start handle, move the choke lever to the CLOSED position.
Adding Fuel Operation Note: Determine the left and right sides of the machine from the normal operating position. 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. Before you Start • Dig away the earth and remove any stones near • Fill the fuel tanks outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. the tree stump that may interfere with your work.
Filling the Fuel Tank WARNING Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. 1. Park the machine on a level surface and engage the parking brake. 2. Shut off the engine and allow the engine to cool. • Avoid prolonged breathing of vapors. 3. Clean around the fuel-tank cap and remove it (Figure 8). • Keep your face away from the nozzle and fuel tank opening. • Keep fuel away from your eyes and skin.
Grinding a Stump Starting the Engine 1. Move the fuel valve to the OPEN position, all the way to the right (Figure 9). 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. g015174 Figure 9 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 in 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 6. Place the air channels in the cyclone housing. 7. Insert cyclone housing into position and make sure that it fits in the upper portion. Servicing the Air Cleaner Important: Do not use force; align it in place before fitting the screws. Service Interval: Before each use or daily—Check the air filter (more often in dirty or dusty conditions). 8. Secure the cyclone housing using the 3 screws.
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 After the first 20 hours/After the first month (whichever comes first) Every 100 hours/Every 6 months (whichever comes first) (Service more frequently if conditions are extremely dusty or sandy.
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. 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 16). g244086 g244099 g031623 Figure 16 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 18). g244101 g206640 g027478 Figure 17 6. Figure 18 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). Service Interval: Every 100 hours—Check the spark plug.
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 21). Figure 20 g014507 Figure 21 1.
7. Cooling System Maintenance Turn the fuel valve to the ON position, all the way to the right, and check for leaks. Note: If it leaks, replace the O-ring. Cleaning the Engine Screen 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.
Belt Maintenance Checking the Drive-Belt Tension Service Interval: Every 25 hours Note: Replace the belt if it shows any signs of wear, cracks, 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. Remove the 2 bolts, 2 washers, and belt guard (Figure 23). g244102 Figure 24 1. Belt 3. 6 to 10 mm (1/4 to 3/8 inch) 2. Belt pushed down Important: To extend the belt life, maintain proper tension.
5. Grinder Maintenance Turn the square head adjusting bolt on the frame clockwise to tighten the belt; turn it counter clockwise to loosen the belt. Replacing the Teeth Important: Important: Make sure to tighten all engine bolts after proper belt adjustment is achieved. 6. 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. Install the belt guard and secure with previously removed hardware.
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. g034223 Figure 28 1.

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.
