8. Shut off the engine and be certain the cutting blade has completely stopped rotating before inverting the Edger, performing maintenance on or working on the machine. 9. If running problems or excessive vibration occur, stop immediately and inspect the unit for the cause. If the cause cannot be determined or is beyond your ability to correct, return the Edger to your servicing dealer for repair. 10. Store fuel and Edger away from open flame, sparks and excessive heat.

Reinstall the air cleaner cover and tighten the knob (Fig. 8).
Installing Shield 2. Install the edger blade, clamping washer and blade bolt (Fig. 12). Note: 3. Align the hole in the boss adapter with the hole in the gearcase (Fig. 12). 4. Insert the 3mm hex wrench into the holes in the boss adapter and gearcase to lock the splined shaft (Fig. 12). 5. Tighten the blade bolt to 100 in.-lbs. (11.3 NSM) (Fig. 12). 6. Remove the 3mm hex wrench from the boss adapter and gearcase (Fig. 12). POTENTIAL HAZARD • Foreign objects can be thrown by Edger.

Never remove the Edger fuel tank cap while the engine is running or right after just stopping the engine. IMPORTANT: Do not use National Marine Manufacturer’s Association (NMMA) or BIA certified oils. This type of 2–cycle engine oil does not have the proper additives for air-cooled, 2–cycle engines and can cause engine damage.
Mixing Gasoline And Oil Fuel Mixture Chart Gasoline IMPORTANT: The engine used on this Edger is of a 2–cycle design. The internal moving parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall contact surfaces, require oil mixed with the gasoline for lubrication. 50:1 2-cycle oil 1 gallon 2.6 oz. 2 gallons 5.2 oz. 5 gallons 12.8 oz.
2. Rest the Edger on the ground. 3. Make sure the Edger blade is clear of any broken glass, nails, wire, rocks or other debris. 4. Keep all bystanders, children and animals away from the working area. 1. Pump the primer bulb at the bottom of the carburetor until fuel can be seen flowing through the fuel return line to the fuel tank (Fig. 13). 2. Move the choke lever to the open ( ) position and move the stop switch to the “ON” position (Figs. 14 and 15). 3.
Idle Speed Adjustment This Edger is equipped with non-adjustable fuel mixture carburetor. The engine idle speed is the only adjustment for the operator. Contact your local authorized Toro Dealer for assistance and servicing. Operation POTENTIAL HAZARD • Foreign objects can be thrown by Edger. POTENTIAL HAZARD • Engine must be running to make some carburetor adjustments. • When engine is running, Edger blade is rotating and other parts are moving.
5. The Edger weight should be evenly distributed between the arms (Fig. 17). 6. Adjust the Edger to the correct cutting depth before you start the engine. (Refer to Setting Depth of Cut on page 11.) Make sure the shield is adjusted to shield the operator from thrown debris (Figs. 17 and 18). 7. Make sure the blade is rotating (at least half throttle) before inserting the blade into the cut. The Edger performs best at full throttle. 8.
IMPORTANT: The air filter screen is designed to fit into the air filter cover ONE WAY ONLY. Make sure the cutouts in the screen fit onto the matching plastic posts in the air filter cover. The fit should be snug (Fig. 20). 6. Reinstall the air filter cover and tighten the knob (Fig. 19). Spark Plug Maintenance Interval • The spark plug should be removed from the engine and checked after each 25 hours of operation. • Replace the spark plug after every 100 hours of operation. Spark Plug Maintenance 1.
Cooling Fin Cleaning 1. 2. With the engine at ambient (room) temperature, loosen the knob and remove the air cleaner cover (Fig. 8). Loosen the knob and lift off the cylinder cover (Fig. 8). 3.

Gearcase Maintenance The gearcase is a sealed unit which has been greased at the factory. No gearcase maintenance or lubrication is required or recommended.
5. Remove the spark plug and squirt a very small amount of oil into the cylinder. POTENTIAL HAZARD • Oil may squirt out of the spark plug opening when you pull the starter handle. 6. Pull the starter handle once. 7. Slowly pull the starter handle to bring the piston to the top of the cylinder (TDC). 8. Reinstall the spark plug. 9.
