Recoil-Start Handle Operation To start the engine, pull the recoil-start handle (Figure 6) quickly to turn the engine over. Refer to Starting the Engine (page 10) for the correct starting procedure. Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating the machine, check Fuel Valve the fluid levels, and remove debris from the machine. Ensure that the area is clear of people and debris.
• Do not use gasoline containing methanol. DANGER • Do not store fuel either in the fuel tank or fuel In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property. • Always place fuel containers on the ground away from your vehicle before filling.
Shutting Off the Engine Performing Daily Maintenance 1. Note: If the engine has been working hard or Before starting the machine each day, perform the Each Use/Daily procedures listed in Maintenance (page 12). is hot, let it run for a minute before releasing the safety bail. This helps to cool the engine before shutting it off. In an emergency, the engine may be shut off immediately. Starting the Engine 1. Move the throttle to the DISENGAGE position.
each sweep, until you have removed the front portion of the stump to ground level (A through D in Figure 10). 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 10). 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—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 17). g205123 g031623 Figure 17 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 19). g205129 g206640 g027478 Figure 18 6. Figure 19 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).
Brake Maintenance Belt Maintenance Adjusting the Parking Brake Adjusting the Drive-Belt Tension 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 set screw on the side of the brake-lever knob. Turn the knob clockwise to tighten the brake; turn the knob counterclockwise to loosen the brake. Service Interval: Before each use or daily Note: Inspect the drive belt through the slot on top of the belt cover.
g242386 g017434 Figure 25 Figure 27 1. Bolt 6. 1. Straightedge Loosen the belt-tension bolt and jam nut. Slide the engine toward the flywheel housing to loosen the belt (Figure 26). 9. 10. 2. Flex of 1 cm (0.40 inch) Ensure that the pulleys are aligned and the engine is parallel with the frame (not angled toward the side), then tighten the 4 engine-plate mounting bolts and the 4 bolts securing the rear of the belt guard to the engine. Install the belt guard and tighten the bolts (Figure 24).
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 28). 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 For storage over 30 days, prepare the machine as follows: 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 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. Removing Debris from the Machine Regular cleaning and washing increases the life span of the machine.
12. Grease the cutter wheel bearings; refer to Greasing the Machine (page 12). 13. Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged. 14. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer. 15. Store the machine in a clean, dry garage or storage area. 16. Cover the machine to protect it and keep it clean.
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.
