Throttle Lever and Safety Bail 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. The safety bail controls the engine. Hold the safety bail against the handle to deactivate the engine kill switch so that the engine starts. Release the safety bail to shut off the engine.
Specifications Operation Note: Specifications and design are subject to change without notice. Cutting Depth Note: Determine the left and right sides of the machine from the normal operating position. 30 cm (12 inches) Length 127 cm (50 inches) Width 56 cm (22 inches) Height 107 cm (42 inches) Weight 47 kg (103 lb) 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.
Adding Fuel DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Use unleaded gasoline (87 pump octane minimum). Leaded, regular gasoline may be used if unleaded is not available. DANGER In certain conditions, gasoline is extremely flammable and highly explosive.
Filling the Fuel Tank 1. Park the machine on a level surface, lower the grinder, and shut off the engine. 2. Allow the engine to cool. 3. Clean around the fuel tank cap and remove it (Figure 9). Figure 10 1. Oil dipstick Figure 9 View may vary depending on model 4. Add unleaded gasoline to the fuel tank, until the level is 6 mm to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. Important: Running the engine with low oil level can cause engine damage.
Starting and Shutting Off the Engine Grinding a Stump Starting the Engine The machine will cut and amputate hands and feet. • Stay in the operator's position while the machine is running and keep away from the cutting wheel. • Keep all bystanders a safe distance from the machine. Stop the machine immediately if any people or animals enter the work area. • Never leave a running machine unattended. Always shut off the engine and verify the cutting wheel has stopped rotating. DANGER 1.
3. Move the machine to the front of the stump and set the parking brake. 4. Move throttle up to the Engage position. The cutting wheel will begin rotating. 5. Swing the cutting wheel to one side (Figure 12), then lower it approximately 13 mm to 25 mm (1/2 inch to 1 inch) into the front-top corner of the stump.
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, gasoline 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.
3. Clean the components with water, detergent, and a brush then dry the components carefully. 3. Remove the wing nut on top of the air filter and remove the paper filter. 4. Place the air channels in the cyclone housing. 4. Tap the paper filter against a fixed surface to remove dust. If the paper filter is still dirty or damaged, replace it. 5. Insert cyclone housing into position and make sure it fits in the upper portion.
Servicing the Spark Plug 6. When the oil has drained completely, install the plug and wipe up any spilled oil. Service Interval: Every 100 hours—Check the spark plugs. Note: Dispose of the used oil at a certified recycling center. Ensure that the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug and a gapping tool/feeler gauge to check and adjust the air gap.
Belt Maintenance Checking the Spark Plug 1. Look at the center of the spark plug (Figure 19). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means that the air cleaner is dirty. Checking the Drive Belt Tension Important: Do not clean the spark plug. Always replace the spark plug when it has a black coating, worn electrodes, an oily film, or cracks.
Adjusting the Drive Belt Grinder Maintenance 1. Remove the belt guard. Replacing the Teeth 2. Loosen the 4 engine mounting bolts, and jam nuts holding the adjustment bolt (Figure 21). 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 will need to rotate and replace them periodically (Figure 22).
Cleaning Removing Debris from the Machine Regular cleaning and washing will increase the life span of the machine. Clean the machine directly after use, before the dirt hardens. Check before cleaning 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 blade bearings after cleaning. Figure 23 1. Tooth 2. Tooth holder 3.
Storage Storing the Machine For storage over 30 days, prepare the unit as follows: 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. Important: You can wash the unit with mild detergent and water. 2. Add a petroleum based stabilizer/conditioner to fuel in the tank. Follow mixing instructions from stabilizer manufacturer. (7.8 ml per L or 1 oz per US gallon).
Troubleshooting Problem Possible Cause Corrective Action 1. The engine switch is in the Off position. 1. Hold the safety bail against the handle. 2. The fuel shutoff valve is closed. 3. The choke is open. 4. The fuel tank is empty. 5. The spark plug wire is loose or disconnected. 2. Open the fuel valve. 3. Close the choke when starting a cold engine. 4. Fill tank with fresh fuel. 5. Check the electrode gap and clean or replace the spark plug. 1. The choke is left on. 1. Open the choke. 2.
