PERSONAL CONDITION AND SAFETY EQUIPMENT  
WARNING  
DANGER  
Power Blower users risk injury to themselves and others if the power blower is used improperly and or safety  
precautions are not followed. Proper clothing and safety gear must be worn when operating a blower.  
Physical Condition --  
Your judgment and physical dexterity may not be good:  
• if you are tired or sick,  
Hearing Protection --

EXTENDED OPERATION/EXTREME CONDITIONS  
To reduce the risk of RSI/CTS, do the  
following:  
Vibration and Cold --  
Avoid using your wrist in a bent,  
extended or twisted position. Instead try  
to maintain a straight wrist position.  
Also, when grasping, use your whole  
hand, not just the thumb and index finger.  
Takeperiodicbreakstominimizerepeti-  
tion and rest your hands.  
Reduce the speed & force in which you  
do the repetitive movement.  
Do exercises to strengthen the hand and  
armmuscles.  
Immediately stop using all power  
equipment and consult a doctor if you  
feel tingling, numbness or pain in the  
fingers, hands, wrists or arms. The  
sooner RSI/CTS is diagnosed, the more  
likely permanent nerve and muscle  
damage can be prevented.  
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 sensations 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, neck, feet, ankles, hands  
and wrists.  
Maintain good blood circulation by performing vigorous arm  
exercises during frequent work breaks and also by not smoking.  
Limit the hours of operation. Try to fill 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 fingers  
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 fingers,  
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). AnextremeRSIconditionisCarpalTunnelSyndrome  
(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.  
EQUIPMENT  
Before operation a complete check of the unit must be performed:  
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or  
replace as needed.  
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO  
NOT operate unit if leaks are found.  
• Keep exhaust area clear of flammable debris. Avoid contact during  
andimmediatelyafteroperation.

KeepASolidStance  
SAFE OPERATION  
• Maintain footing and balance at all times. Do not stand  
on slippery, uneven or unstable surfaces. Do not work  
in odd positions or on ladders.  
Determine Operation Area --  
• Do not perform Maintenance or Assembly procedures  
with engine running.  
• 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 (50 ft.) while the blower is in use.  
• Take wind conditions into account: avoid open doors  
and windows.  
• Provide all operators of this equipment with the  
Operator's Manual and instructions for safe operation.  
• Do not point blower at people or animals.  
• Start unit on ground with throttle at idle. Check that  
blower pipe is not blocked by the ground or by any  
objects.  
NoiseControl  
• Follow local noise regulations on sound levels and  
hours of operations. Use only during appropriate hours.  
• Never use a higher speed setting then necessary to  
perform a task. The higher the engine speed the louder  
the blower noise.  
• Be a good neighbor.  
AvoidHotSurfaces  
• During operation, the muffler or catalytic muffler and  
surrounding cover may become extremely hot. Avoid  
contact during and immediately after operation. Always  
keep exhaust area clear of flammable debris. Allow the  
engine and muffler to completely cool before performing  
any maintenance activity.  
WARNING  
DANGER  
Do not operate this product indoors or in inad-  
equately ventilated areas. Engine exhaust contains  
poisonous emissions and can cause serious injury or  
death.  
KeepAFirmGrip  
• Hold handle with fingers together encircling the handle.

Parts Required: None, if you are careful.  
IMPORTANT  
To maintain proper engine operating temperatures, cooling air  
must pass freely through the cylinder fin area. This flow of air  
carries combustion heat away from the engine.  
Overheating and engine seizure can occur when:  
• Air intakes are blocked, preventing cooling air from reaching the  
cylinder.  
• Dust and grass build up on the outside of the cylinder. This build up  
insulates the engine and prevents the heat from leaving.  
Removal of cooling passage blockages or cleaning of cooling fins is  
considered “Normal Maintenance”. Any failure attributed to lack of  
maintenance is not warranted.  
Cleaning Grill  
1. Remove accumulated debris from intake grill between backpack  
frame and blower housing.  
Cleaning Cylinder Fins  
A
1. Remove engine cover (four screws), pull cover away from engine.  
Clean cylinder fins (A) to allow cooling air to pass freely.
