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 and or
safety precautions are not followed. Proper clothing and safety gear must be worn when operating a trimmer.
Physical Condition --
Your judgment and physical dexterity may not be good:
Hearing Protection --
ECHO recommends wearing hearing protection whenever
unit is used.
• if you are tired or sick,
• if you are taking medication,
• if you have taken alcohol or drugs.
Proper Clothing --
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DONOTWEARSHORTS,
Operate unit only if you are physically and mentally well.
• DONOTWEARTIES,SCARVES,JEWELRY.
Eye Protection --
Wear eye protection that meets ANSI Z87.1 or CE
requirements whenever you operate the trimmer.
Wear sturdy work shoes with non-skid soles;
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
Hand Protection --
Wear no-slip, heavy duty work gloves to improve your
grip on the Trimmer/Brush Cutter handles. Gloves also
reduce the transmission of machine vibration to your
hands.
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 exer-
cises 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 move-
ment.
• 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.

Plastic/Nylon Blades may be used where ever the nylon line head
is used. DO NOT use this blade for heavy weeds or brush!
8 Tooth Weed/Grass Blade P/N 69600120331 is designed for grass,
garden debris and thick weeds. DO NOT use this blade for brush or
heavy woody growth, 3/4" in. (19 mm) diameter or larger.
Brush/Clearing Blade P/N 69500120331 is designed for cutting brush
and woody growth up to 76 mm (3" in.) diameter.
Use Shoulder/Waist Harness P/N 99944200200 Use of the Shoulder/
Waist Harness is recommended for ALL Trimmer/Brush Cutter use, not
just Blade operation. The Shoulder/Waist Harness when used in a
trimming operation with nylon line head suspends the trimmer from the
operator's shoulder and reduces operator fatigue.
During blade operation, the same fatigue reduction is achieved. Safety
to the operator is also enhanced by preventing blade contact with the
operators hands and feet by restricting trimmer movement.
NOTE
In case of Emergency, pull up on the Quick Release Collar to
disconnect the trimmer from the harness.

COOLING SYSTEMS CLEANING
Level2.
Tools required: Cross-head screwdriver, 3 mm hex wrench, pointed
wood stick
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.
1. Remove spark plug lead and throttle linkage end from the carbure-
torswivel.

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 mainte-
nance. 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
Tools required: Flat file (preferred), Electric grinder if special care is
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.
