1. Checking and Relling Engine Oil
1) Follow the procedure below when the engine oil is cold i.e. the mist blower has
not been running.
Inspection: Set the blower down on a level surface and remove the oil cap.
Verify that the oil level is within the upper and lower limit marks on
the oil level gauge. If the oil is not up to the 100 mL level, ll up with
new oil.
Adding Oil: Set the mist blower down on a level surface and remove the oil cap.
Fill the oil up to the upper limit of the oil level gauge.
2) On average, engine oil normally needs to be added after every 20 hours of
operation. This interval for every change in oil corresponds to refueling the mist
blower approximately 10-15 times.
3) Please change the oil whenever it becomes dirty or signicantly changes color.
(Refer to P. 23 for the oil change procedure and frequency.)
Recommended oil: MAKITA genuine oil or SAE10W-30 oil of API type SF grade or
better (4 stroke motor oil for automobiles)
Oil capacity: Approximately 0.22 L (220 ml)
CAUTION:
• If the mist blower is not stored in an upright position, the oil may ow from the level gauge into the engine and give a false reading when
checking the oil level. This may result in inadvertently overlling whenever adding engine oil. Always store in an upright position.
If the upper oil level limit is exceeded, this can result in the oil becoming dirty and white smoke from burning excess oil.
Check Point #1: Concerning the oil cap when adding oil
Wipe off dirt and grime around the opening before removing the oil cap.
Remove the oil cap and place it on a clean surface so that it does not accumulate any sand, dirt, or other foreign bodies. These may stick
to the cap and adulterate the engine oil if proper care is not taken. Dirty oil containing sand, dirt, or foreign bodies may cause excessive
wear on the engine due to improper lubrication and result in a breakdown.

Check Point #2: If oil is spilled when adding oil
Oil spillage on the outside on the mist blower may result in the engine oil becoming dirty or adulterated. Therefore, please wipe off any oil
spillage before starting the engine.
2. Fuel supply
WARNING:
• When supplying the fuel, be sure to observe the following instructions to prevent ignition or re:
Fuel supply must be made in a place free of re. Never bring the re (smoking, etc.) near to the place of fuel supply.
Stop the engine and allow the engine to cool down before fuel supply.
Open the fuel tank cap full of fuel slowly. The fuel may sprout out under internal pressure.
Take care not to spill the fuel. Any spilled fuel must be wiped clean.
Carry out fuel supply in a well-ventilated place.
Handle the fuel with care.
Fuel sticking to the skin or entering an eye may cause allergies or irritation. When any physical abnormality is detected, consult the
medical specialist immediately.
STORAGE PERIOD OF FUEL
Fuel should be used up within a period of 4 weeks, even if it is kept in a special container in a well-ventilated shade.
If a special container is not used or if the container is not covered, fuel may deteriorate in one day.
Storage of machine and rell tank
Keep the machine and tank at a cool place free from direct sunshine.
Never keep the fuel in the cabin or trunk.
FUEL
The engine is a four-stroke engine. Be sure to use an automobile gasoline (regular gasoline or premium gasoline).
Points for Fuel
Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles.
Use of deteriorated oil will cause irregular startup.
When refueling the fuel, be sure to stop the engine and make sure that the engine cools down.
REFUELING METHOD
Loosen the tank cap a little so that there will be no difference in atmospheric pressure.
• Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that the refuel port will be oriented upward. (Never rell fuel full to the
oil rell port.)
After refueling, securely tighten the tank cap.
• If there is any aw or damage on the tank cap, replace it.
The tank cap will wear. Replace the tank cap every two to three years.

OPERATION
1. Starting
WARNING:
Never attempt engine start in a place where the unit was refueled. When
starting the engine, keep a distance of at least 3 m (10 feet).
Otherwise, it will may cause ignition or re.
Exhaust gas from the engine is toxic. Do not operate the engine in a poorly-
ventilated place, such as in a tunnel, building, etc.
Operating the engine in the poorly-ventilated place may cause poisoning by
exhaust gas.
In case of detection of any abnormality in sound, odor, vibration after start,
stop the engine immediately and carry out inspection.
If the engine is operated without attending such abnormality, an accident
may occur.
Make sure that the engine stops when the stop switch is set to “O” position.
1) When the engine is cold, or when the fuel it refueled
(1) Set this machine on a at space.
(2) Set the stop switch to “ I ” position.
(3) Verify that the cruise control lever is in the low-speed position.
(4) Continue to push the primer pump until fuel enters into the primer pump.
In general, fuel enters into the carburetor by 7 to 10 pushes.
If the primer pump is pushed excessively, an excess of gasoline returns to
the fuel tank.
