Method of operation
Use the blower only in good light and visibility. Beware of slippery or wet
areas, ice and snow (risk of slipping), and narrow space.
Always ensure a safe footing.
Never work on unstable surfaces or steep terrain.
Do not work from ladders or high places. Otherwise it may result in
personal injury.
To reduce the risk of personal injury, do not direct air blast towards
bystanders, since the high pressure of the air ow could injure eyes and
could blow small objects at great speed.
Never insert any foreign object into the air intake of the machine or into
the nozzle of the blower. It will damage the fan wheel and may cause
serious injury to the operator or bystanders as a result of the object or
broken parts being thrown out at high speed.
Pay attention to the direction of the wind, i.e., do not work against the
wind.
To reduce the risk of stumbling and loss of control, do not walk backward
while operating the machine.
Always shut off the engine before cleaning or servicing the unit or
replacing parts.
Take a rest to prevent loss of control caused by fatigue. We recommend
to take a 10 to 20-minute rest every hour.
Keep all parts of your body away from hot surfaces.
Avoid blowing debris towards people, pets, open windows, or cars when
using unit.
To reduce damage from vibration and/or damage to the ears, operate the
machine at low speed if possible and limit the time of operation.
Operate the machine only at reasonable hours. Do not operate the
blower in the morning or late at night when people might be disturbed.
Comply with times listed in local ordinances.
It is recommended for using rakes and brooms to loosen debris before
blowing.
Before blowing, slightly dampen surfaces in dusty conditions or use
water mist sprayer if necessary.
Conserve water by using blowers instead of hoses for many lawn and
garden applications, including areas such as gutters, screens, patios,
grills, porches, and gardens.
Adjust the length of the blower nozzle so that the stream can work close
to the ground.
To reduce sound levels, limit the number of pieces of equipment used at
any one time.
After using blowers and other equipment, CLEAN UP! Dispose of debris in
trash receptacles.

1. Checking and Relling Engine Oil
1) Perform the following procedure, with the engine cooled down.
Otherwise skin burn may result.
Inspection: Put the blower on a at surface and remove the oil
cap.
Check the oil gauge (1). Make sure that the oil level is
within the upper (2) and lower (3) limit marks. If the oil
is not up to the 100 ml (3.4 oz) level (4), ll up with
new oil.
Filling oil: Put the blower on a at surface and remove the oil
cap.
Fill the oil up to the upper limit of the oil level gauge.
2) On average, engine oil needs to be added after every 20 hours of
operation (every 10 – 15 refuellings).
3) Change the oil whenever it becomes dirty or signicantly changes
color. (Refer to “Replacement of engine oil” 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 220 ml (7.4 oz)
NOTE:
If the 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 overlling whenever adding engine oil. Always store the blower in an upright position.
If the engine oil is exceeded, the oil may spill from the breather of the air cleaner and make surrounding parts dirty, or white smoke may appear
due to burning excessive oil.
Replacement of Oil “Oil cap”
Remove dust or dirt near the oil rell port, and detach the oil cap.
Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or wear on
the engine parts, which will result in troubles.
