WARNING DANGER
USERS RISK INJURY TO THEMSELVES
AND OTHERS IF THE UNIT IS USED
IMPROPERLY, AND/OR SAFETY
PRECAUTIONS ARE NOT FOLLOWED.
PROPER CLOTHING AND SAFETY GEAR
MUST BE WORN WHEN OPERATING UNIT.
•Read this Manual carefully. Be sure you
understand how to operate this unit properly
before you use it.
•Wear non-skid sole shoes. Do not wear open-
toed shoes or operate unit while bare footed.
•Wear proper clothing to legs and other
exposed parts of your body.
•Wear eye, breathing and hearing protection
devices.
•Secure hair so it is above shoulder length.
•Use caution when handling fuel. The fuel tank
may be under pressure. Always loosen the
fuel cap and wait for pressure to be eqalized
before removing the cap. Put the fuel caps
back tightly on both the fuel can and the fuel
tank. Move at least 3 m from the re-fueling
point and be sure there is no leakage of fuel
from the fuel cap or the fuel system before
startingtheengine.
•Wipe any spilled fuel off the unit.
•Operatethispetrolenginepoweredequipment
inawell-ventilated area only.
•Do not operate this unit in closed areas- such
as garages, inside building, sheds, etc.
•Start the unit on the ground with the throttle
lever at start position. Do not start if the pipe
is obstruced by the ground or any other
object.
•Do not start engine on operator’s back.
•Inspect area where this unit will be used.
Remove stones, metal objects and any other
object that could cause injury or damage the
unit.
•Do not use a unit on unstable footings.
•Do not allow other persons or pets in the area
when starting or using the unit.
•Do not point the nozzle in the direction of
peopleoranimals.
•Keep a firm grip on the unit at all times.

3
•Keep hands and body away from hot surfaces
such as silencer and cylinder area when
handling the unit to prevent from heat injury.
•Never attempt to use incomplete machine or
one fitted with unauthorized modification.
•A fully loaded unit will change your
equilibrium. Extra precautions should be
taken to maintain your footing and balance.
•Check the shoulder harnesses are not
tangled with any control levers when you put
the unit on your back.
•This unit is designed for upright use only, do
not lay down or lean excessively to avoid
leakage of chemicals when operating and
transporting.
REDUCE NOISE
NOTE
Before operating the unit, check and follow
local regulations concerning sound level and
hours of operation.
•Avoid using units when people are likely to be
disturbed, such as late at night or early in the
morning.
•Operate the unit at the lowest possible throttle
setting that gets the job done.
•Make sure the silencer works well. Also check
the air intakes and the air filter to make sure
the unit is working properly.
•Use only one piece of equipment at a time.
•Wear hearing protection when operating the
unit.
REDUCE CHANCES OF DAMAGE
•Do not use the unit in a windy day or rainy
day to avoid chemical drift.
•Before starting the job, check wind direction.
Avoid blowing in the direction of open doors
and windows, cars, pets, children or anything
that could be harmed by chemical.
•Dust and mist blowing must be done
leewardly. Choose morning or eving when it is
not so windy, and the ground temperature
reserves, so as to minimize dispersion losses
and enhance chemical adhesion effect and
for less hazardous operation.

PHYSICALCONDITION
Your judgement and/or dexterity may be impaired
if you are ill, are taking medication, and/or have
taken alchol or other substances known to affect
the way you would normally function. Operate this
unit if you are in good physical and mental health.
WARNING DANGER
AVOID DIRECT CONTACTOR INJESTION
OF CHEMICALS YOU MAY USE. CONSULT
THE LABEL THE CHEMICALS, YOU MAY
USE FOR ADDITIONAL WARNING AND
PRECAUTIONS AS WELL AS UNIT
IMMEDIATELY IF YOU FEEL SICK OR
EXCESSIVE FATIGUE DURING
OPERATION. SEE A DOCTOR IF THIS
CONDITION PERSISTS.
HOT HUMID WEATHER
Heavy protective clothing can increase operator
fatigue which may lead to heat stroke. Delay
heavy work until the temperature drops.
EYE, BREATHING AND HEARING
PROTECTION
•Wear eye protection goggles.
•Wear breathing protection such as officially
approved toxic dust and mist respirator.
•Wear hearing protection. If this guideline is
not followed, hearing loss can occur.
WEAR PROPER CLOTHING
•Snug fitting, durable clothing should be worn.
Trousers should have long legs. DO NOT
WEAR SHORTS. Do not wear loose fitting
clothing, scarfs, neckties, jeweiry or any item
that may be drawn or tangled in the fan.
•Wear chemical resisting work clothes.

wear open toed shoses or operate unit bare
footed.
•Wear no-slip, heavy duty work gloves to
improve your grip on the pipe.
Wearing rubber gloves and cap to prevent
direct contact with chemicals.

Painful or numb
fingers?
See your doctor
VIBRATION AND COLD
It is believed that a condition called Raynaud’s
Phenomenon which affects the fingers of certain
individuals may be brought about by exposure to
vibration and cold. Exposure to vibration and cold
may cause tingling and burning, followed by loss
of color and numbness in the fingers. The
following precautions are strongly recommended
because the minimum exposure which might
trigger the ailment is unknown.
• Keep your body warm, especially the head
and neck, feet and ankles, and hands and
wrists.
• Maintain good blood circulation by performing
vigorous arm exercises during frequent work
breaks, and also by not smoking.
• Limit the number of hours of operation.
Try to fill each day with jobs where operating
the power sprayer or other hand-held power
equipment is not required.
• If you experience discomfort, redness and
swelling of the fingers, followed by whitening
and loss of feeling, consult your physician
before exposing yourself further to cold and
vibration.
REPETITIVE STRESS INJURIES
It is believed that overusing the muscles and
tendons of the fingers, hands, arms and
shoulders may cause soreness, swelling,
numbness, weakness and extreme pain to the
areas just mentioned. Ceratin repetitive hand
activities may put you at a high risk for developing
a repetitive stress injury (RSI).
To reduce the risk of RSI, do the following :
•Avoid using your wrist in a bent, extended or
twisted postion.
•Take periodic breaks to minimize repetition
and rest your hands. Reduce the speed and
force in which you do the repetitive
movement.
•Do exercises to strengthen hand and arm
muscles.
•See a doctor if you feel tingling, numbness or
pain in your fingers, hands, wrists or arms.
The sooner RSI is diagnosed, the more likely
permanent nerve and muscle damage can be
prevented.
