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:
• 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 when-
ever 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.
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.
• DONOTWEARSHORTS,

Wear sturdy work shoes with non-skid soles;
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
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.

SAFE OPERATION
Determine Operation Area
• Provide all operators of this equipment with the Operator's Manual
and instructions for safe operation.
15 m (50 ft.)
• 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
UseProperClothing&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.
WARNING
DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
AvoidHotSurfaces
• 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.
KeepAFirmGrip
• Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles
KeepASolidStance
• 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.

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 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.

Tools required: Cleaningbrush, 25or50mm(1or2in.)mediumbristle
paint brush.
Parts required: 90008REPOWERTM AIR&FUELFILTERKIT.
1. Close choke (Cold Start Position). This prevents dirt from entering
the carburetor throat when the air filter is removed. Brush accumu-
lated 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:
• still fits the cavity in the air cleaner cover.
• is installed with the original side out.
NOTE
Carburetor adjustment may be needed after air filter cleaning/
replacement. See Carburetor Adjustment Section.

COOLING SYSTEMS CLEANING
Level2.
Tools required: Cross Head Screwdriver, 3 mm Hexagon wrench,
PointedWoodStick,CleaningBrush,25-50mm(1-2in.)mediumbristle
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.

Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with EPA Phase 1 and California Emission Regulations. In
addition, the carburetor is equipped with HI and LO needle
adjustment limiters that prevent settings outside acceptable limits.
1. Before adjusting the carburetor, clean or replace the air filter and
spark arrester screen.
2. The trimmer line should be extended to the cut-off knife.
3. Start engine and run for several minutes to reach operating
temperature.
4. Stop engine. Turn HI speed needle (A) CCW (counter clockwise) to
stop. Turn LO speed needle (B) midway between full CCW and CW
(clockwise) stops.
5. Idle Speed Adjustment.
• Start engine and turn “idle” speed adjustment screw (C) CW
until the blades begin to turn, then turn the screw CCW until
blades stop turning. Turn screw CCW an additional 1/4 turn.
6. Accelerate to full throttle for 2-3 seconds to clear excess fuel from
engine then return to idle. Accelerate to full throttle to check for
smooth transition from idle to full throttle. If engine hesitates, turn
LO needle (B) CCW an additional 1/8 turn and repeat acceleration.
Continue adjusting until smooth acceleration results.
7. Check HI speed RPM at W.O.T. (Wide Open Throttle). HI speed
RPM should be set to specifications found on page 11 "Specifica-
tions" of this manual.
8. Check idle speed and reset if necessary. If a tachometer is available,
idle speed should be set to the specification found on page 11
