SAFETY INSTRUCTIONS
PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING
DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly
or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a
trimmer/brushcutter.
Proper Clothing
Physical Condition
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DONOTWEARSHORTS,
Your judgment and physical dexterity may not be good:
• if you are tired or sick,
• if you are taking medication,
• DONOTWEARTIES,SCARFS,JEWELRY.
• if you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Wear protective hair covering to contain long hair.
Eye Protection
Eye protection that meet ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
Wear sturdy work shoes with nonskid soles:
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
Hand Protection
Hot Humid Weather
Heavy protective clothing can increase operator fatigue,
which may lead to heat stroke. Schedule heavy work for
early morning or late afternoon hours when temperatures
are cooler.
Wear no-slip, heavy-duty work gloves to improve your
grip on the handles. Gloves also reduce the transmission
of machine vibration to your hands.
Hearing Protection
Wear hearing protection. ECHO recommends wearing
hearing protection whenever unit is used.
EXTENDED OPERATION/EXTREME CONDITIONS
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 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 trimmer 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.
To reduce the risk of RSI/CTS, do the following:
• Avoid using your wrist in a bent, extended, or twisted position.
Instead, try to maintain a straight wrist position. Also, when grasp-
ing, use your whole hand, not just the thumb and index finger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive
movement.
• Do exercises to strengthen the hand and arm muscles.
• 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.

SPARK PLUG
Level2.
Tools required: T-Wrench (combination socket wrench and screw
driver), Feeler gauge, brush.
Parts Required: REPOWERTM Tune-UpKit P/N90074
1. Remove spark plug and check for fouling, worn and rounded
center electrode.
2. Clean the plug or replace with a new one. DO NOT sand blast to
clean. Remaining sand will damage engine.
3. Adjust spark plug gap by bending outer electrode.
4. Tightensparkplugto145-155kg/cm(125-135in.lb.).
COOLING SYSTEM CLEANING
Level2.
Tools required: Crossheadscrewdriver, 3mmhexwrench, 25-50mm
(1 or 2 in.) cleaning brush
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.

SHARPENING METAL BLADES
Three styles of metal blades are approved for use on the ECHO Brush
Cutter. The 8-tooth blade can be sharpened during normal maintenance.
The clearing blade and 80 tooth blade require professional service.
Before sharpening, CLOSELY inspect blade for cracks (look at the
bottom of each tooth and the center mounting hole closely), missing
teeth and bending. If ANY of these problems are discovered, replace
the blade.
When sharpening a blade, always remove the same amount of materials
from each tooth to maintain balance. A blade that is not balanced will
cause unsafe handling due to vibration and can result in blade failure.
8-tooth Blade
Tool required: Flatfile(preferred), electricgrinderifspecialcareis
used, round (rat tail) file for gullet (radius).
1. File each tooth at a 30 degree angle a specific number of times,
eg. 4 strokes per tooth. Work your way around the blade until
all teeth are sharp.
2. DO NOT file the 'gullet' (radius) of the tooth with the flat file.
The radius must remain. A sharp corner will lead to a crack and
bladefailure.
IMPORTANT
If an electric grinder is used, use care not to overheat teeth, do not
allow tips/tooth to glow red or turn blue. DO NOT place blade in
cooling water. This will change the temper of the blade and could
result in blade failure.
3. After sharpening teeth, check each tooth radius for evidence of a
square (sharp) corner. Use the round (rat tail) file to renew the
radius.
