• Blindness can occur from objects that are thrown or ricocheted even
with shield in place. Operators, helpers and bystanders must wear
ANSI Z87.1 approved eye protection.

• Always wear hearing protection when operating unit.

• Prevent accidental contact with unit and any cutting attachment.
Maintain a 50 ft. (15M) radius, DANGER ZONE surrounding the

should be in the DANGER ZONE.

• Beware of KICKOUT (blade thrust) when using blades. Special
precautions are necessary for blade operation, see your Operator's
and Safety Manuals. ONLY install ECHO approved blades on Brush
Cutters (SRM) models equipped with proper blade shield, U-handles,
harness, blade collar, nut and cotter pin.

• Blade/Cutting attachment does not stop immediately after releasing

OPERATOR'S MANUAL

SAFETY INSTRUCTIONS

PERSONAL

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.

CONDITION AND SAFETY EQUIPMENT

W ARNING DANGER

5

Physical Condition --

Your judgment and physical dexterity may not be good:

• if you are tired or sick,

• if you are taking medication,

• if you have taken alcohol or drugs.

Operate unit only if you are physically and mentally well.

Hearing Protection --

ECHO recommends wearing hearing protection whenever
unit is used.

Proper Clothing --

Wear snug fitting, durable clothing;

• Pants should have long legs, shirts with long sleeves.

• DO NOT WEAR SHORTS,

• DO NOT WEAR TIES, 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;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

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 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.

6

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). 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 following:

• 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.

• 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.

EQUIPMENT

W ARNING DANGER

• 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.

operating condition.

• Check that front (loop) handle and optional shoulder/waist harness
are adjusted for safe, comfortable operation. See Assembly for proper
adjustment.

• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.

8. CUT-OFF KNIFE - Automatically trims line to the correct length: 5" - after head is tapped on the ground. If trimmer is

operated without a cut-off knife the line will become too long, the engine will overheat and engine damage may occur.

9. PLASTIC DEBRIS SHIELD ASSEMBLY - Included in plastic bag (co-pack). MUST be installed on unit before use,

see Assembly Instructions. Shield assembly includes the Cut-Off Knife and Safety Decal. Mounts on the Gear
Housing Assembly just above the cutting attachment. Helps protect the operator by deflecting debris produced
