WORKING CONDITIONS
1. Refrain from operating the blower if you are tired, ill, or upset,
or if you are under the influence of alcohol, drugs or
medication
2. To reduce the risk of hearing loss associated with sound
levels, hearing protection is required.
3. To reduce the risk of injury associated
with thrown objects, always wear eye
protection and foot protection.
Approved protective goggles must
comply with standard ANSI Z87.1 in the
USA or EN 166 in EU countries.
4. To reduce the risk of injury associated
with the inhalation of dust, use a face
filter mask in dusty conditions.
5. Wear rubber-soled shoes or shoes with
some other form of anti-slip protection
to help protect you against falling.
6. To reduce the risk of injury associated
with objects being drawn into rotating
parts, do not wear loose clothing,
scarves, neck chains, hair longer than
shoulder length, or other loose
material.
7. Prolonged use of a blower, exposing the operator to
vibrations and cold, may produce whitefinger disease
(Raynaud’s phenomenon), the symptoms of which include
tingling and burning sensations followed by loss of color and
numbness in the fingers. All factors which contribute to
whitefinger disease are not known, but cold weather,
smoking diseases or physical conditions as well as long
periods of exposure to vibration are mentioned as factors. In
order to reduce the risk of whitefinger disease, the following
precautions are strongly recommended
a) Keep your body warm. Never use the blower during rain.
b) Take more than 5 minutes of break in a warm place fre-
quently.
c) Maintain a firm grip at all times, but do not squeeze the
handles with constant, excessive pressure.
d) If you feel discomfort, redness and swelling of your fingers
or any other part of your body, see a doctor before it gets
worse.
8. This machine produces an electromagnetic field during
operation. This field may under some circumstances interfere
with active or passive medical implants. To reduce the risk of
serious or fatal injury, we recommend persons with medical
implants to consult their physician and the medical implant
manufacturer before operating this machine.
WORKING CIRCUMSTANCE
1. To reduce the risk of injury associated
with exhaust fume inhalation, do not
operate in unventilated area. The
exhaust gases contain harmful carbon
monoxide.
2. Avoid using the blower where stable
footing and balance are not assured.
3. Never operate the machine in high
wind, bad weather, potentially explosive atmosphere, when
visibility is poor or in very high or low temperatures.
(Our recommended use environment is below 40 degrees C
(104 degrees F).)
AVOID NOISE PROBLEM
NOTE
Check and follow the local regulations as to sound levels
and hours of operations for blower.
1. Operate power equipment only at reasonable hours, not early
in the morning or late at night when people might be
disturbed. Comply with times listed in local ordinances.
2. To reduce sound levels, limit the number of pieces of
equipment used at any one time.
3. Operate power blowers at the lowest possible throttle speed
to do the job.
4. Check your equipment before operation, especially the
muffler, air intakes and air filters.
WORKING PLAN
To reduce the risk of health damages, avoid excessive use and
take sufficient time to rest.
FUEL
WARNING
To reduce the risk of fire and burn injury:
a) Handle fuel with care. It is highly
flammable.
b) Do not smoke while handing fuel.
c ) Do not refuel a hot engine.
d) Do not refuel a running engine.
e) Avoid spilling fuel or oil. Always wipe
unit dry before using.
f ) Move at least 10 ft. (3 meters) away
from the fueling point before starting the engine.
g) Always store gasoline in a container approved for flammable
liquids.
h) Make sure the unit is properly assembled and in good
operating condition.
i ) Do not use the blower near a fire, as
aiming the blower in the direction of a
flame may cause flammable
substances to ignite.
BEFORE STARTING THE ENGINE
Each time before starting the engine, inspect the entire unit to
see if every part is in good order and is securely tightened in
place. If any damage is found in the fuel line, the exhaust line, or
the ignition wiring, do not use the blower until it has been
repaired.
IMPORTANT
Before starting operation, always make sure to check if any
obstacles are left inside the volute case and net. The
obstacles may cause serious injury or damage to fan and
volute case.
