Operating Safety
1. THIS HANDHELD BLOWER CAN CAUSE
SERIOUS INJURIES. Read the instructions care-
fully. Be familiar with all controls and the proper
use of the Handheld Blower.
2. Avoid using the Handheld Blower near rocks,
gravel, stones and similar materials which can
become dangerous projectiles.
3. Keep children, bystanders and animals outside a
50ft. (15m) radius surrounding the area of opera-
tion.

Operating Techniques
1. Operate power equipment only at reasonable
hours — not early in the morning or late at night
when people may be disturbed. Comply with the
times listed in local ordinances. Usual recommen-
dations for hours of operation are 9:00 a.m. to
5:00 p.m., Monday through Saturday.
2. To reduce noise levels, limit the number of pieces
of equipment used at any one time and operate
power blowers at the lowest possible throttle
speed to do the job.
3. Check your equipment before operation, especial-
ly the muffler, air intakes and air filters.
4. Use rakes or brooms to loosen debris before blow-
ing.
5. In dusty conditions, slightly dampen surfaces or
use a mister attachment when water is available.
6. Conserve water by using power blowers instead of
hoses for many lawn and garden applications,
including areas such as gutters, screens, patios,
grills, porches and gardens.
7. Use the full blower nozzle extension so the air
stream can work close to the ground.
8. Watch out for children, pets, open windows, or
freshly washed cars and blow debris safely away.
9. After using blowers and other equipment, CLEAN
UP! Dispose of debris in trash receptacles.

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.

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.

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.

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 85
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 METHANOL,
GASOLINE CONTAINING METHANOL,
GASOHOL CONTAINING MORE THAN
10% ETHANOL, PREMIUM GASOLINE, OR
WHITE GAS BECAUSE ENGINE FUEL SYS-
TEM 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
Handheld Blower is of a 2-cycle design. The
internal moving parts of the engine, i.e., crank-
shaft 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.

Mixing Instructions
IMPORTANT: Never mix gasoline and oil
directly in the Handheld Blower 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 Handheld Blower.
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 Handheld Blower.
6. When refilling the Handheld Blower 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 “Before
Operation” section of this manual (page13).
2. Rest the Handheld Blower on the ground.

system. To start a “cold” engine properly, perform 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.)

Idle Speed Adjustment
This Handheld Blower is equipped with non-adjustable
fuel mixture carburetor. The engine idle speed is the
only adjustment for the operator.
Wear the recommended personal protective equipment
and observe all safety instructions.
When the throttle trigger and the throttle setting lever is
idle position the engine should return to an idle speed
between 2700 and 3300 RPM. The engine should not
stall (stop running) at engine idle speed.
To adjust the engine idle speed, rotate the idle speed
adjustment screw on the carburetor.
• Turn the idle speed screw in (clockwise) to
increase the engine idle speed.
• Turn the screw out (counterclockwise) to decrease
the engine idle speed.
If idle speed adjustment is necessary, and after
adjustment the engine stalls, stop using the Handheld
Blower immediately!
Contact your local authorized Maruyama Dealer for
