safe operaTIon
DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
Setup/Check Operation Area
• Review area to be cleared. Look for potential hazards such as stones
or metal objects.
• Spectatorsandfellowworkersmustbewarned,andchildrenand
animals prevented from coming nearer than 15 m while the blower
is in use.
• Operate only in well ventilated areas: do not operate in enclosed
areassuchasinsidegarages,shedsorbuildings.
• Take wind conditions into account: avoid open doors and windows.
Use Proper Clothing and Equipment
• Beforestartingtheunit,equipyourselfandanyotherpersonwork-
ing within the 15 m Safety Zone with the required Protective Equip-
ment and clothing.
• Start unit on ground with throttle at idle. Check that blower pipe is

exTended operaTIon/exTreme CondITIons
Vibration and Cold --
ItisbelievedthataconditioncalledRaynaud’sPhenomenon,which
affectsthengersofcertainindividualsmaybebroughtaboutby
exposure to vibration and cold. Exposure to vibration and cold may
cause tingling and burning sensations followed by loss of color and
numbnessinthengers.Thefollowingprecautionsarestronglyrec-
ommended because the minimum exposure which might trigger the
ailment is unknown.
• Keepyourbodywarm,especiallythehead,neck,feet,ankles,
hands and wrists.
• Maintain good blood circulation by performing vigorous arm exer-
cises during frequent work breaks and also by not smoking.
• Limitthehoursofoperation.Trytolleachdaywithjobswhere
operating the blower or other hand-held power equipment is not
required.
• Ifyouexperiencediscomfort,rednessandswellingofthengers
followedbywhiteningandlossoffeeling,consultyourphysician
before further exposing yourself to cold and vibration.
Repetitive Stress Injuries --
Itisbelievedthatoverusingthemusclesandtendonsofthengers,
hands,armsandshouldersmaycausesoreness,swelling,numbness,
weakness and extreme pain in those areas. Certain repetitive hand
activities may put you at a high risk for developing a Repetitive Stress
Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome
(CTS),whichcouldoccurwhenyourwristswellsandsqueezesavital
nerve that runs through the area. Some believe that prolonged exposure
to vibration may contribute to CTS. CTS can cause severe pain for
monthsorevenyears.ToreducetheriskofRSI/CTS,dothefollow-
ing:
• Avoidusingyourwristinabent,extendedortwistedposition.In-
steadtrytomaintainastraightwristposition.Also,whengrasping,
useyourwholehand,notjustthethumbandindexnger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force in which you do the repetitive move-
ment.
• Do exercises to strengthen the hand and arm muscles.
• Seeadoctorifyoufeeltingling,numbnessorpaininthengers,
hands,wristsorarms.ThesoonerRSI/CTSisdiagnosed,themore
likely permanent nerve and muscle damage can be prevented.
