OIL AND FUEL RECOMMENDATIONS

RECOMMENDED OIL TYPE

Use high quality oil formulated for use in 2-cycle, air-cooled engines. Mix the oil according to the instructions on the 2-cycle engine oil container, 40:1 (2.5%).

RECOMMENDED FUEL TYPE

Always use clean, fresh, unleaded petrol (gasoline).

OIL AND FUEL MIXING INSTRUCTIONS

Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.

Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded petrol, 40:1 (2.5%). Do not mix them directly in the tank.

OPERATING INSTRUCTIONS

STARTING INSTRUCTIONS

1. Mix petrol (gasoline) with oil. Fill fuel tank with petrol/oil mixture. See Oil and Fuel Mixing Instructions.
2. Put the ignition switch in the START (I) position (Fig. 7).

MAINTENANCE AND REPAIR INSTRUCTIONS

Tine Removal and Replacement

All 4 tines should be replaced at the same time because they will wear evenly through normal use. Work on one side at a time.

WARNING: To prevent serious personal injury, always wear heavy gloves when handling the tines.

1. Put the On/Off Stop Control in the STOP (O) position and disconnect the spark plug wire.
   NOTE: It may be necessary to lay the cultivator back in a horizontal position on a flat level surface with the upper handle touching the ground.
2. Remove the click pin (4) from each end of the tine shaft. Slide the tines off of the shaft (Fig. 11).
3. Clean and oil the shaft.
4. When you are reinstalling tines, lay out the tines and compare them to those shown in Figure 12. Note specifics about each tine: its hub, curvature and lettering ("A" or "B"). This will help make sure that you are placing the correct tines in the correct order.

NOTE: If you look closely, you can see a slight curvature in the tine tips. These curves should point toward the front of the cultivator when the tines are installed. Figure 12 shows the curve in each tine.
5. Using Figures 11 and 12 for reference, slide on the new tines with the hubs facing outward.

The tines are stamped "A" or "B." The tine order should be "B, A, B, A" from left to right when facing the cultivator from the front.

1. Secure the new tines to the shaft with click pins (4). It may be necessary to wash the dirt off the tines and shaft for ease of removal.

AIR FILTER MAINTENANCE

Removing the Air Filter/Muffler Cover

1. Place the choke lever (1) in the position 2 (Fig. 13).
   NOTE: The choke lever must be in position 2 to remove the air filter/muffler cover.
2. Remove the four screws (2) securing the air filter/muffler cover (Fig. 13). Use a flat blade or T-20 Torx bit screwdriver.
3. Pull the cover from the engine. Do not force.

Cleaning the Air Filter

Clean and re-oil the air filter every 10 hours of operation. It is an important item to maintain. Failure to maintain your air filter properly can result in poor performance or can cause permanent damage to your engine.

1. Remove the air filter/muffler cover. See Removing the Air filter/Muffler Cover.
2. Remove the air filter (3) from inside the air filter/muffler cover (Fig. 14).
3. Wash the filter in detergent and water (Fig. 15). Rinse the filter thoroughly. Squeeze out excess water. Allow it to dry completely.
4. Apply enough clean oil to lightly coat the filter (Fig. 16).
5. Squeeze the filter to spread and remove excess oil.
6. Replace the air filter inside the air filter/muffler cover (Fig. 14).

NOTE: Operating the unit without the air filter and air filter/muffler cover assembly, will Void the warranty.

Reinstalling the Air Filter/Muffler Cover

1. Place the air filter/muffler cover over the back of the carburetor and muffler.
   NOTE: The choke lever must be in position 2 to install the air filter/muffler cover.
2. Insert the four (4) screws into the holes in the air filter/muffler cover (Fig. 13) and tighten. Use a T-20 Torx bit screwdriver. Do not over tighten. Do not force.

MAINTENANCE AND REPAIR INSTRUCTIONS

Check Fuel Mixture

Old and/or improperly mixed fuel is usually the reason for the unit not running properly. Drain and refill the tank with fresh, properly mixed fuel prior to making any adjustments.

Clean Air Filter

The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict air flow and change the air/fuel mixture. This is often mistaken for an out of adjustment carburetor. Check the condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Adjuster

If after checking the fuel mixture and cleaning the air filter the engine

still will not idle, adjust the idle speed adjuster as follows.

1. Start the engine and let it run about 2-3 minutes at a high speed (full throttle) to warm up.

NOTE: Ensure the tines are not in contact with the ground when adjusting the idle.

1. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips into the hole in the air filter/muffler cover (Fig. 18). Turn the idle speed adjuster in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.

NOTE: The tines should not rotate when the engine idles.

1. If the tines rotate when the engine idles, turn the idle speed adjuster counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed.

Checking the fuel mixture, cleaning the air filter, and adjusting the idle

speed screw should solve most engine problems.

If not and:

The engine will not idle,
- The engine hesitates or stalls on acceleration,
There is a loss of engine power,

Have the carburetor adjusted by an authorized service dealer.

REPLACING THE SPARK PLUG

Use a Champion RDJ7Y spark plug (or equivalent). The correct air gap is 0.5mm (0.020 in.). Remove the plug after every 50 hours of operation and check its condition.

1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug.
3. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.5 ~mm (0.020 in.) using a feeler gauge (Fig. 19).
4. Install a correctly gapped spark plug in the cylinder head. Tighten by turning the 5/8 in. socket clockwise until snug.

Do not over tighten.

CLEANING

Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils

such as pine and lemon, and solvents such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth.

MAINTENANCE AND REPAIR INSTRUCTIONS

STORAGE

• Never store the unit with fuel in the tank where fumes may reach an open flame or spark.
• Allow the engine to cool before storing.
• Store the unit in a dry place, locked up or up-high to prevent unauthorized use or damage. Keep out of the reach of children.

LONG TERM STORAGE

If the unit will be stored for an extended time, use the following storage procedure.

1. Drain all fuel from the fuel tank and drain into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days.
2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor.
3. Allow the engine to cool. Remove the spark plug and put 30ml (1 oz.) of any high quality motor oil or 2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the unit after storage.
