Snap the strap hook into the ring on the drive shaft. To
detach the strap quickly from the Brushcutter, pull
upward on the red band.
Before Operation
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
engine.

DANGER
POTENTIAL HAZARD
• In certain conditions gasoline is extreme-
ly 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 out-
doors, 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.

8. Move the Trimmer/Brushcutter at least 10 feet (3
m) away from the fueling location and fuel stor-
age container before starting the engine.
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 oxygenat-
ed or reformulated gasoline, with an octane rating of 89
or higher. To ensure freshness, purchase only the quan-
tity 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
Trimmer/Brushcutter 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 spe-
cially formulated to meet the requirements of
high-performance, low-emission air-cooled 2-
cycle engines. Use of other oils may lead to ser-
vice 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 —
232025-04  12.11.3011:49 AM  ページ18
232025-10.indd 17 13/12/25 14:51

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.
Mixing Instructions
IMPORTANT: Never mix gasoline and oil
directly in the Trimmer/Brushcutter 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 Trimmer/Brushcutter.
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 Trimmer/Brushcutter.
6. When refilling the Trimmer/Brushcutter 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 momen-
tarily before filling the fuel tank.
8. Always use a spout or funnel when fueling to
reduce fuel spillage.
9. Fill the tank only to within 1/4-1/2 inch (6 mm-13
mm) from the top of the tank. Avoid filling to the
top of the tank filler neck.
Starting And Stopping
Before Starting The Engine
1. Fill the fuel tank as instructed in the Operation
section of this manual (US-16).
2. Rest the Trimmer/Brushcutter on the ground.
3. Make sure the cutting attachment is clear of any
broken glass, nails, wire, rocks or other debris.
4. Keep all bystanders, children and animals away
from the working area.
Cold Starting Procedure
This Trimmer is equipped with a fuel primer and a
choke system. To start a “cold” engine properly, per-
form the following procedure:
1. Pump the primer bulb at the bottom of the carbu-
retor until fuel can be seen flowing through the
fuel return line to the fuel tank.
(Flowing fuel should be almost clear, not foamy
or full of bubbles.)

move the choke lever to the open ( ) position.
If the engine stops running before you move the
choke lever to the open ( ) position:
A. Go ahead and open the choke.
B. Make sure the throttle trigger is set to the idle
position.
C. Pull the starter grip until the engine starts.
Hot Restart
To start an engine that is already warmed up (hot
restart), or if the ambient temperature exceeds 68°F
(20°C):
1. Pump the primer bulb at the bottom of the carbu-
retor until fuel can be seen flowing through the
fuel return line to the fuel tank.
2. Move the choke lever to the open ( ) position
and move the stop switch to the “ON” position.
3. Leave the throttle trigger in the idle position and
pull the starter grip.
4. If the engine fails to start after three to four pulls,
follow the instruction in the Cold Starting
Procedure section (US-18).
If the engine fails to start after you follow the
above procedures, contact an authorized
Maruyama dealer.
To Stop The Engine:
1. Release the throttle trigger.
2. Slide the stop switch to the “STOP” position.
