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/CONDITION-
ER 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 Multi -
Cutter 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.
10 ft. (3 m) minimum
50:1
