Operation Note: Determine the left and right sides of the machine from the normal operating position.

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. You should also know and have marked the locations of all utility lines.

Before you Start Dig away the earth and remove any stones near the tree

stump that may interfere with your work. Check that the ground is free of foreign objects, such as electrical cables, barbed wire, etc.

Cut or trim the stump using a power saw.

Review all the safety decals on the machine.

Ensure that you are familiar with safety regulations and shutdown procedures described in this manual.

Ensure that all guards are in place and in good condition.

Ensure that the blades and cutters are in place and in good condition.

Ensure that the work area, cutter, and stump in particular are free from metallic objects such as wire, nails, etc. that could be thrown out and injure persons in the vicinity and damage the equipment.

Adding Fuel 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. 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 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

Do not operate without the entire exhaust system in place and in proper working condition.

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. Always place gasoline containers on the ground

away from your vehicle before filling. Do not fill gasoline containers inside a vehicle or

on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Important: Do not use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol

because the fuel system could be damaged. Do not mix oil with gasoline.

Using Stabilizer/Conditioner Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

Cleans the engine while it runs.

Eliminates gum-like varnish buildup in the fuel system, which causes hard starting.

Important: Do not use fuel additives containing methanol or ethanol.

Add the correct amount of gas stabilizer/conditioner to the gas.

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank 1. Park the machine on a level surface, lower the grinder,

and stop the engine.

2. Allow the engine to cool.

3. Clean around the fuel-tank cap and remove it (Figure 6).

Figure 6

1. Fue- tank cap

4. Add unleaded gasoline to the fuel tank, until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.

Important: This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.

5. Install the fuel-tank cap securely.

6. Wipe up any gasoline that may have spilled.

Checking the Engine-oil Level Service Interval: Before each use or daily

1. Tilt the machine so the engine is level, and stop the engine.

2. Allow the engine to cool.

3. Clean around the oil dipstick.

4. Remove the dipstick and wipe the end clean.

5. Slide the dipstick fully into the dipstick tube without threading it into the filler neck.

6. Pull the dipstick out and look at the end. The oil should be to the top of the upper limit range (Figure 7).

Figure 7

1. Oil dipstick

Important: Running the engine with low oil level can cause engine damage. This type of damage is not covered by warranty. The engine is equipped with an oil alert system that will automatically stop the engine before the oil level falls below the safe limit.

7. If the oil level is low, slowly pour only enough oil into the crankcase to raise the level to the upper limit.

Important: Do not overfill the crankcase with oil because the engine may be damaged.

8. Replace the dipstick.

Each tooth is indexed with 3 positions so you can rotate it twice, exposing a new sharp edge before replacing the tooth. To rotate a tooth, loosen the nut securing the tooth (Figure 20). Push the tooth forward and rotate it 1/3 of a turn, bringing an unused edge to the outside. Align the flat washer, tooth and tooth holder. Torque the nut securing the tooth to 37 to 45 N-m (27 to 33 ft-lb).

To replace a tooth, remove the nut securing the tooth, then install a new tooth, nut and flat washer in the same position (Figure 20). The flat washer goes between the holder and the nut. Torque the nut securing the tooth to 37 to 45 N-m (27 to 33 ft-lb).
