PERSONAL CONDITION AND SAFETY EQUIPMENT
W ARNING 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.
6
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.
Eye Protection --
Wear eye protection that meets ANSI Z87.1 or CE requirements
whenever you operate the trimmer.
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.

Determine Operation Area
• Provide all operators of this equipment with the Operator's Manual
and instructions for safe operation.
• Review the area to be trimmed. Look for hazards that could contribute
to unsafe conditions.
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while
the trimmer is in use.
Operation
Use Proper Clothing & Equipment
• Before starting the unit, equip yourself and any other person
working within the 15 m (50 ft.) Safety Zone with the required
Protective Equipment and clothing.
W ARNING DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
15 m (50 ft.)
Keep A Firm Grip
• Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles
Keep A Solid Stance
• 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. Do not over reach.
Avoid Hot Surfaces
• During operation, the complete unit, especially the drive shaft
housing and the bearing housing may become very hot, too hot to
touch. Avoid contact during and immediately after operation.
8
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). 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 & force in 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.

Your ECHO trimmer is designed to provide many hours of trouble free service. Regular scheduled maintenance will help
your trimmer achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take your
unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have the
ECHO Dealer do it, each maintenance task has been graded. If the task is not listed see your Echo dealer for repairs.
SKILL LEVEL
Level 1 = Easy to do. Most required tools come with unit.
Level 2 = Moderate difficulty. Some specialized tools may be required.
Level 3 = Experience required. Specialized tools are required.
ECHO offers REPOWER Maintenance Kits and Parts to make your maintenance job easier. Just below each task heading
are listed the various part numbers required for that task. See your ECHO dealer for these parts.

Tools required: Cleaning brush, 25 - 50 mm (1 or 2 in.) medium bristle
paint brush.
Parts required: Air Filter P/N 13031054130
1. Close choke (Cold Start Position). This prevents dirt from entering
the carburetor throat when the air filter is removed. Brush accumulated dirt from the air cleaner area.
2 . Remove the air cleaner cover. Clean and inspect the element for
damage. If element is fuel soaked and very dirty, replace.
3 . If element can be cleaned and reused, be certain it:

one end bent into a hook. Clean rag, funnel, and an approved fuel
container.
Parts required: Fuel Filter P/N 13120507320
W ARNING DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing or
handling.
1 . Use a clean rag to remove loose dirt from around fuel cap and
empty fuel tank.

COOLING SYSTEMS CLEANING
Level 2.
Tools required: Cross Head Screwdriver, 3 mm Hexagon wrench,
Pointed Wood Stick, Cleaning Brush, 25 - 50 mm (1 or 2 in.) medium
bristle paint brush.
Parts Required: None.
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-
tor swivel.
2. Remove the four screws that retain the cover. Two at the top of the
Recoil Starter, two on either side of the front. Lift the cover from the
engine and lay to the front of the trimmer.
22
NOTE
The throttle linkage remains assembled to the cover and the spark
plug lead and grommet remain installed.
IMPORTANT
DO NOT use a metal scraper to remove dirt from the cylinder fins.
3 . Use the wooden stick or brush to remove dirt from the cylinder fins.
4 . Remove grass and leaves from the grid between the starter and fuel
tank.
5 . When installing the cover, be certain the tab of the metal deflector
shield is in the slot of the cover.
EXHAUST SYSTEM
Spark Arrestor Screen
