Frequently Asked Questions - MC-E Maruyama

What fuel mixture does the Maruyama MC-E use?

The MC-E requires a 50:1 ratio of unleaded gasoline to high-quality 2-stroke oil. Always use fresh fuel and shake well before filling.

How do I replace the cutting line?

1. Stop the engine and disconnect the spark plug. 2. Remove the spool cap. 3. Cut a length of line (approx. 6 m). 4. Wind the line onto the spool in the direction indicated. 5. Feed ends through eyelets and reassemble.

Why won't my MC-E start?

Common causes: stale fuel, dirty spark plug, clogged air filter, or flooded engine. Check fuel, clean/replace spark plug and air filter, and try starting with choke off if flooded.

How often should I clean the air filter?

Clean the air filter after every 10 hours of use or more frequently in dusty conditions. Replace it once a season or if damaged.

Can I use a metal blade on the MC-E?

Yes, the MC-E is compatible with optional metal blades for heavier brush. Ensure you use the correct blade adapter and always wear protective gear.

What is the correct spark plug gap?

The spark plug gap should be 0.6-0.7 mm (0.024-0.028 inches). Use a feeler gauge to adjust.

How do I store the MC-E for winter?

Drain the fuel tank, run the engine until it stops, clean the unit, apply light oil to metal parts, and store in a dry place. Remove the spark plug and add a teaspoon of oil in the cylinder, then pull the starter slowly.

What is the warranty period for Maruyama MC-E?

Maruyama typically offers a 2-year limited warranty for consumer use and 1 year for commercial use. Check your local dealer for exact terms.

Why does the cut quality deteriorate?

Dull or worn cutting line, insufficient line length, or debris buildup. Replace line, ensure proper line advance, and clean the cutting head.

Where can I find spare parts?

Authorized Maruyama dealers and online retailers stock genuine parts. Always use OEM parts to maintain performance and safety.

Before Operation

Chain Oil (Multi-Cutter with Pruner Attachment)

The chain and guide bar are lubricated by a centrifugal pump. The oil discharge rate is controlled by the oil discharge adjustment screw on the top of the pruner head.

Remove the oil tank filler cap fill the tank, then replace the cap.

IMPORTANT: Only use oil designed for lubricating chain saw chains and guide bars. Do not use waste oil. Never run the chain dry. In temperatures below freezing, check the chain oil viscosity (pour point). If the oil is not rated for use below freezing, it may not provide adequate lubrication, resulting in damage to the oil pump, chain and guide bar.

IMPORTANT: When filling the oil tank for the first time, or when the tank is completely empty, wait approximately 60-90 seconds before starting the Pruner. This will give the oil time to flow from the tank to the pump. Otherwise, an air lock can occur which will prevent oil from moving through the pump. This will result in damage to the chain and guide bar.

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" (6 mm to 13mm) 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 fume 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.

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

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.

1. Always shut off the engine before refueling.

Never remove the fuel tank cap while the engine is running or right after just stopping the engine.

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

Only use a two-cycle engine oil formulated for use in high performance, air cooled two cycle engines.

MARUYAMA brand 2-cycle oil is formulated for use in high performance, air cooled two-cycle engines.

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.

Do not use automotive motor oil. This type of oil does not have the proper additives for air cooled, 2-cycle 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 ISO-PROPYL. 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 MultiCutter 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.

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 2-cycle Oil Mix, or equivalent ISO-L-EGD & JASO FD oil with a minimum 89 octane high Quality gasoline. Maruyama 2-cycle oil is specially formulated to meet the requirements of high-performance, low-emission air-cooled 2-cycle 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.

Fuel Mixture Chart

Gasoline	50:1 2-cycle oil
1 gallon	2.6 oz.
2 gallons	5.1 oz.
5 gallons	12.8 oz.

1 litre	20 ml
5 litre	100 ml

Mixing Instructions

IMPORTANT: Never mix gasoline and oil directly in the Multi - Cutter 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 Multi - Cutter.

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 Multi - Cutter.

6. When refilling the Multi - Cutter 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.
