Oil and Fuel

1. Do not smoke near fuel.

2. Mix and pour fuel outdoors and where there are

no sparks or flames.

3. Always shut off the engine before refueling.

Never remove the fuel tank cap while the engine

is running or just right after sopping the engine.

4. Always open the fuel tank cap slowly to release

any possible overpressure inside the tank.

5. Do not overfill the fuel tank. Stop filling 1/4-1/2

inch (6 mm-13 mm) from the top of the tank.

6. Tighten the fuel tank cap carefully but firmly after

refilling.

7. Wipe up any spilled fuel before starting the

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 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.

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.

Recommended Oil Type

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

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 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.

50:1

− US-17 −

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.

2 gallons 5.1 oz.

5 gallons 12.8 oz.

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.
