Before Operation

Oil and Fuel

DANGER

POTENTIAL HAZARD

• In certain conditions gasoline is extremely flammable and highly explosive.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 mm to 13 mm) 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.

• Always shut off the engine before refueling. Never remove the fuel tank cap while the engine is running or just right after stopping the engine.

• Always open the fuel tank cap slowly to release any possible overpressure inside the tank.
• Do not overfill the fuel tank. Stop filling 1/4 - 1/2 in. (6mm - 13mm) from the top of the tank.

WARNING

POTENTIAL HAZARD

Gasoline contains gasses that can build up pressure inside a gas tank.

WHAT CAN HAPPEN

• Fuel can be sprayed on you when removing gas cap.

HOW TO AVOID THE HAZARD

• Remove fuel cap slowly to avoid injury from fuel spray.

• Tighten the fuel tank cap carefully but firmly after refilling.

• Wipe up any spilled fuel before starting the engine.
• Move the Hedge trimmer at least 10 ft. (3m) away from the fueling location and fuel storage container before starting the engine.

1. Do not smoke near fuel.
2. Mix and pour fuel outdoors and where there are no sparks or flames.

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 engincs 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 Hedge trimmer 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 ISO-L-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.

Gasoline 50:1 two-stroke oil

1 gallon 2.6 oz

2 gallons 5.1 oz

5 gallons 12.8 oz

1 liter 20 mL

5 liters 100 mL

Mixing Instructions

IMPORTANT: Never mix gasoline and oil directly in the Hedge trimmer 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 Hedge trimmer.
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 Hedge trimmer.
6. When refilling the Hedge trimmer 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. (6 mm-13 mm) from the top of the tank. Avoid filling to the top of the tank filler neck.

Maintenance

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 Hedge trimmer 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 operated.

WARNING

POTENTIAL HAZARD

• Engine must be running to make carburetor adjustments.
• When engine is running, blades are moving and other parts are moving.

WHAT CAN HAPPEN

• Contact with moving blades or other moving parts could cause serious personal injury or death.

HOW TO AVOID THE HAZARD

• Keep hands, feet and clothing away from cutting head and other moving parts.
• Keep all bystanders and pets away from unit while making carburetor adjustments.

The cutting blades may be moving during idle speed adjustment. Wear the recommended personal protective equipment and observe all safety instructions. Keep hands and body away from the blades.

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 blades must not 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.

• 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 cutting head rotates or the engine stalls, stop using the Hedge Trimmer immediately!
