Antes de Utilizar

Diagram illustrating two different techniques for climbing a slope, with one method showing a broken structure and the other demonstrating a tool path.

1. Do not overfill the fuel tank. Stop filling 1/4-1/2 in. (6mm-13mm) from the top of the tank.
2. Tighten the tank fuel cap carefully but firmly after refilling.
3. Wipe up any spilled fuel before starting the engine.
4. Move the Cultivator at least 10 ft (3m) away from the fueling location and fuel storage container before starting the engine.

Recommended Oil Type

Only use a two-stroke engine oil formulated for use in high-performance, air-cooled two-stroke engines. MARUYAMA brand two-stroke oil is formulated for use in high-performance, air-cooled two-stroke engines.

IMPORTANT: Do not use National Marine Manufacturer's Association (NMMA) or BIA certified oils. This type of two-stroke engine oil does not have the proper additives for air cooled, two-stroke engines and can cause engine damage.

Do not use automotive motor oil. This type of oil does not have the proper additives for air-cooled, two-stroke engines and can cause engine damage.

Recommended Fuel Type

Use clean, fresh lead-free gasoline, including oxygenated or reformulated gasoline, with an octane rating of 89 or higher. To ensure freshness, purchase only the quantity of gasoline that can be used in 30 days. Use of lead-free gasoline results in fewer combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary or recommended.

Use of Fuel Additives

IMPORTANT: NEVER USE ALCOHOL, GASOHOL CONTAINING MORE THAN 10% ALCOHOL BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RESULT.

DO NOT USE FUEL ADDITIVES OTHER THAN THOSE MANUFACTURED FOR FUEL STABILIZATION DURING STORAGE SUCH AS MARUYAMA'S STABILIZER/CONDITIONER OR A SIMILAR PRODUCT. MARUYAMA'S STABILIZER/CONDITIONER IS A PETROLEUM DISTILLATE BASED CONDITIONER/STABILIZER. MARUYAMA DOES NOT RECOMMEND STABILIZERS WITH AN ALCOHOL BASE SUCH AS ETHANOL, METHANOL OR ISOPROPYL. ADDITIVES SHOULD NOT BE USED TO TRY TO ENHANCE THE POWER OR PERFORMANCE OF MACHINE.

Mixing Gasoline and Oil

IMPORTANT: The engine used on this Cultivator is of a two-stroke 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.

Failure to add oil to the gasoline or failure to mix oil with the gasoline at the appropriate ratio will cause major engine damage which will void your warranty.

For your fuel premix, use MARUYAMA Premium two-stroke Oil Mix, or equivalent ISOL- EGD & JASO FD oil with a minimum 89 octane high Quality gasoline. MARUYAMA two-stroke oil is specially formulated to meet the requirements of high-performance, low-emission air-cooled two-stroke engines. Use of other oils may lead to service issues which may Not be covered by your warranty.

Fuel Mixture

The fuel: oil ratio is 50 parts gasoline to 1 part oil or 50:1.

Note: Never use a mixing ratio less than 50:1 regardless of the oil package mixing instructions. Ratios less than 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of lubrication to the internal moving parts of the engine and can cause damage.

Refer to the chart above.

Mixing Instructions

IMPORTANT: Never mix gasoline and oil directly in the Cultivator fuel tank.

1. Always mix fuel and oil in a clean container approved for gasoline.
2. Mark the container to identify it as fuel mix for the Cultivator.
3. Use regular unleaded gasoline and fill the container with half the required amount of gasoline.
4. Pour the correct amount of oil into the container then add the remaining amount of gasoline.
5. Close the container tightly and shake it momentarily to evenly mix the oil and the gasoline before filling the fuel tank on the Cultivator.
6. When refilling the Cultivator fuel tank, clean around the fuel tank cap to prevent dirt and debris from entering the tank during cap removal.
7. Always shake the premix fuel container momentarily before filling the fuel tank.
8. Always use a spout or funnel when fueling to reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 in. (6mm-13mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

Starting and Stopping

Maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or individual; however, warranty repairs must be performed by a dealer or service center authorized by MARUYAMA Manufacturing Company, Inc.

The use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of the emission control system and may have a bearing on the outcome of a warranty claim.

Maintenance on today's low-emission engines is even more critical for longest life and best performance. Particularly critical are air and fuel filters, spark plug heat range, cooling air intake area and proper gaps of coil and plug.

Idle Speed Adjustment

This Cultivator is equipped with non-adjustable fuel mixture carburetor. The engine idle speed is the only adjustment for the operator.

WARNING

- Idle speed adjustment should be checked each time the unit is operate.

WARNING

POTENTIAL HAZARD

• Engine must be running to make carburetor adjustments.
- When engine is running, Attached Tool is rotating/moving and other parts are moving.

WHAT CAN HAPPEN

- Contact with rotating/moving tool or other moving parts could cause serious personal injury or death.

HOW TO AVOID THE HAZARD

- Keep hands, feet and clothing away from attached tool and other moving parts.

- Keep all bystanders and pets away from unit while making carburetor adjustments.

The Attached Tool may be rotating/moving during idle speed adjustment. Wear the recommended personal protective equipment and observe all safety instructions.

Keep hands and body away from the Attached Tool.

Mantenimiento

When the throttle trigger is released, the engine should return to an idle speed between 2700-3300 RPM, or just below the clutch engagement speed. The Attached Tool must not rotate/move and the engine should not stall (stop running) at engine idle speed.

To adjust the engine idle speed, rotate the idle speed adjustment screw on the carburetor. [#38-1]

• Turn the idle speed screw in (clockwise) to increase the engine idle speed.
• Turn the screw out (counter-clockwise) to decrease the engine idle speed.

If idle speed adjustment is necessary, and after adjustment the Attached Tool rotates/moves or the engine stalls, stop using the Cultivator immediately!

Contact your local authorized MARUYAMA Dealer for assistance and servicing.

• The air filter should be cleaned daily, or more often when working in extremely dusty conditions.
• Replace after every 100 hours of operation.

Air Filter Cleaning [#38-2]

1. Loosen the knob and remove the air filter cover.
2. Remove the foam element and fi Iter screen from the air fi Iter body.
3. Clean the foam element and filter screen with warm, soapy water. Let the screen and element dry completely.
4. Apply a light coat of motor oil (SAE 30 or equivalent viscosity) to the foam element and squeeze out all excess oil.
5. Reassemble the filter screen and foam element to the air filter body.
6. Reinstall the air filter cover and tighten the knob.

Filtro del Aire

• The fuel filter should be replaced after every 100 hours of operation.
• Fuel filters needing more frequent replacement may indicate debris in fuel tank.

Fuel Filter Replacement [#39-1]

The fuel filter is attached to the end of the fuel pick-up hose inside the fuel tank. To replace the fuel filter:

1. Make sure the fuel tank is empty.
2. Remove the fuel cap.
3. Using a wire hook, gently pull the fuel filter out through the fuel filler opening. Use caution not to "fishhook" the fuel hose. Replace immediately if punctured!
4. Grasp the fuel hose next to the fuel filter fitting and remove the filter, but do not release the hose.
5. While still holding on to the fuel hose, attach the new fuel filter.
6. Drop the new fuel filter back into the fuel tank.
7. Make sure that the fuel filter is not stuck in a corner of the tank, and that the fuel hose is not doubled over (kinked) before refueling.

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 [#39-2]

1. Twist the high tension lead boot on the spark plug back and forth a couple of times to loosen the boot, then pull the boot off of the spark plug.
2. Remove the spark plug.
3. Clean the electrodes with a stiff brush.
4. Adjust the electrode air gap to .024-.028 in. (0.6-0.7 mm).
5. Replace the spark plug if it is oil-fouled, damaged, or if the electrodes are worn down.
6. Do not overtighten the spark plug when installing. The tightening torque is 95-148 in·lbs. (10.7-16.6 N·m).
7. Always use only the specific heat range of spark plug. This is particularly critical with today's low-emission engines. For best results, use the exact replacement.

• The cylinder cooling fi ns should be cleaned after every 25 hours of operation, or once a week, whichever comes fi rst.
• Air must flow freely around and through the cylinder cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will increase the operating temperature of the engine, which can reduce engine performance and shorten engine life.

Cooling Fin Cleaning

1. With the engine at ambient (room) temperature, loosen the knob and remove the air filter cover.
2. Twist the high tension lead boot on the spark plug back and forth a couple of times to loosen the boot, then pull the boot off of the spark plug.
3. Loosen the knob and lift off the cylinder cover.
4. Clean all dirt and debris from the cooling fins and from around the cylinder base.
5. DO NOT overlook cleaning of the cooling air intake area below the crankcase and above the fuel tank! This area must be free of debris and obstruction for the engine to cool properly.
6. Reinstall the cylinder cover and the air fi Iter cover.

- Muffler surface becomes hot when Cultivator is in operation and remains hot for some time after the engine is shut off.

WHAT CAN HAPPEN

- Contact with hot muffler surfaces could cause a burn.

HOW TO AVOID THE HAZARD

- Make sure the muffler is cool before inspecting and cleaning the spark arrester.
