Safety Precautions

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.
