Important - Maruyama MCV31R Manuel Du Propriétaire Et De L'utilisateur

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 aircooled, 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
aircooled, 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 85 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 METHANOL, GASOLINE CONTAINING METHANOL, GASOHOL
CONTAINING MORE THAN 10% ETHANOL, PREMIUM GASOLINE, OR WHITE GAS
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 Chain Saw 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, only use a quality oil designed for 2-cycle air cooled engines.
Maruyama 50:1 2-cycle Oil is formulated to meet the requirements of high-performance,
air-cooled two-cycle engines.
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.
50:1
