Operation DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Never fill the fuel tank inside an enclosed trailer. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck.
because the fuel system could be damaged. Do not mix oil with gasoline. 6. Wipe up any gasoline that may have spilled. Checking the Engine Oil Level Using Stabilizer/Conditioner Service Interval: Before each use or daily Use a fuel stabilizer/conditioner in the machine to provide the following benefits: 1. Tilt the machine so the engine is level, and stop the engine. • Keeps gasoline fresh during storage of 90 days or less. 2. Allow the engine to cool.
Starting and Stopping the Engine Grinding a Stump Place the machine into position with the cutting wheel near the front-top edge of the stump. Starting the Engine DANGER 1. Move the fuel valve to the Open position, all the way to the right (Figure 11). 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.
DANGER 2 1 A rotating cutting wheel is very dangerous and can cut and amputate hands and feet. 4 3 Stay at the operating position and be sure that the cutting wheel has come to a complete stop before doing anything else. 5 6 7 8 g014502 Figure 12 8. Raise the cutting wheel until center of cutting wheel is just above top of the stump. 9. With the cutting wheel off to one side, release the parking brake and advance the machine forward, reset the parking brake. 10.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important: The machine may be tipped backward or on its side to facilitate access for cleaning or service, but no longer than 2 minutes. If the machine is held in this position for too long, the engine can be damaged by gasoline draining into the crankcase. Should this happen, perform an extra oil change on the engine.
Engine Maintenance Important: Pump grease in slowly and carefully to prevent damage to the bearing seals. 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.
Oil Type: Detergent oil with an API service of SJ or higher. Crankcase Capacity: .63 qt (.6 liters) Viscosity: SAE 10W-30 is recommended for general use. Changing the Engine Oil Service Interval: After the first 25 hours Every 100 hours Yearly or before storage 1. Start the engine and let it run five minutes. This warms the oil so it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely. 3.
Underneath the fuel valve is a sediment cup to catch dirt in the fuel. 1. Move the fuel valve to the Off position, all the way to the left. 2. Unscrew the sediment cup. Make sure not to misplace the o-ring (Figure 17). Figure 18 2. Wire 1. Spark plug 3. Clean around the spark plug. 4. Remove the spark plug and the metal washer. 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.
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. Shut off the engine and wait for all rotating parts to stop. 2. Remove belt guard retaining screws (Figure 20). 4 Figure 21 1. Bolt 3. Engine mount bolt 2. Jam Nut 3.
Grinder Maintenance Checking the Cutting Wheel Blades Service Interval: Before each use or daily Among the most critical elements of the machine is the cutting wheel blades. They are also the most subject to damage and wear. In the course of grinding stumps they not only make contact with the wood, but they also encounter numerous abrasives and objects, such as dirt, stones, and occasionally a large rock or buried scrap.
Cleaning Storage For storage over 30 days, prepare the unit as follows: Removing Debris from the Machine 1. Remove dirt and grime from the external parts of the entire unit, especially the engine.
