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.
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 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 contain-
er 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 momentar-
ily to evenly mix the oil and the gasoline before
filling the fuel tank on the Hedge trimmer.
