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 193 cm (76 inches) Width 75 cm (29.5 inches) Height 107 cm (42 inches) Weight 109 Kg (240 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 because the fuel system could be damaged. Do not mix oil with fuel. Use unleaded fuel (87 pump octane minimum). Leaded, regular fuel may be used if unleaded is not available. Using Stabilizer/Conditioner DANGER Use a fuel stabilizer/conditioner in the machine to provide the following benefits: 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.
Starting and Shutting Off the Engine Checking the Engine-Oil Level Service Interval: Before each use or daily 1. Tilt the machine so the engine is level, and shut off the engine. Starting the Engine 2. Allow the engine to cool. 1. Move the fuel valve to the OPEN position, all the way to the right. 3. Clean around the oil dipstick. Note: If your model is equipped with an engine with an On/Off switch, move the switch to the ON position. 4. Remove the dipstick and wipe the end clean. 5.
Grinding a Stump DANGER 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. Shut off 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.
6. Raise the cutting wheel, release the parking brake, and move the machine forward a few centimeters (inches). Set the parking brake. 7. Repeat steps 5 and 6 until you have completely removed the stump (E through H in Figure 9). 8. Move throttle to the DISENGAGE position, push the handle down enough to raise the cutting wheel off the ground. Wait for the cutting wheel to stop rotating then release the parking brake and pull the machine away from 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, 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 Servicing the Air Cleaner Service Interval: Before each use or daily The cyclone air filter collects the largest contaminant particles, which collect in the container. When you can see a layer of dirt at the bottom of the container, clean the cyclone housing, air channels, and air-intake screen. Servicing the Cyclone Air Filter Service Interval: Every 50 hours 1. Remove the 3 screws holding the cyclone housing. 2. Remove the housing with the air-intake screen and remove the air channels.
Servicing the Engine Oil Cleaning the Sediment Cup Oil Type: Detergent oil with an API service of SJ or higher. Service Interval: Every 100 hours Yearly or before storage Crankcase Capacity: 2 L (2.1 qt) Underneath the fuel valve is a sediment cup to catch dirt in the fuel. Viscosity: SAE 10W-30 is recommended for general use. Changing the Engine Oil 1. Move the fuel valve to the OFF position, all the way to the left. Service Interval: After the first 25 hours 2.
Brake Maintenance Removing the Spark Plug 1. Lower the grinder and shut off the machine; Refer to Shutting Off the Engine (page 10). 2. Pull the wire off the spark plug (Figure 15). Adjusting the Parking Brake 1. Loosen the set screw on side of brake lever knob. 2. Turn the knob clockwise to tighten the brake; adjust counter clockwise to loosen the brake. Note: The left wheel should lock completely when the brake is set. 3. Tighten the setscrew. Figure 15 2. Wire 1. Spark plug 3.
Belt Maintenance 6. Lay a straightedge across clutch and flywheel pulleys, tighten belt-tension bolt so there is 1 cm (0.40 inch) of flex in the belt when pushing down with 6.8 kg (15 lb) force, at mid-span (when re-tensioning a belt in use) or with 8 kg (18 lb) force when installing a new belt (Figure 19). 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.
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 20). 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 Storage Removing Debris from the Machine Storing the Machine For storage over 30 days, prepare the machine 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. Regular cleaning and washing increases the life span of the machine. Clean the machine directly after use, before the dirt hardens.
Troubleshooting Problem The engine does not start. Possible Cause Corrective Action 1. The safety bale 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 valve. 4.
