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,becausetheminimum exposure which mighttriggerthe
ailmentisunknown.
• Keep your body warm, especially the head, neck, feet, ankles, hands,
and wrists.
• Maintain good blood circulation by performing vigorous armexercises
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, ex-
tended, 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.
• Takeperiodicbreakstominimizerepetition
and rest your hands.
• Reduce the speed and force with which
you do the repetitive movement.
• Do exercises to strengthen the hand and
armmuscles.
• Immediately stop using all power equip-
ment and consult a doctor if you feel
tingling, numbness, or pain in the fingers,
hands, wrists, or arms. The sooner RSI/
CTSisdiagnosed, themorelikelyperma-
nent nerve and muscle damage can be
prevented.
EQUIPMENT

operate unit until leakage is repaired.
R+M
2IMPORTANT
Spilled fuel is a leading cause of
hydrocarbon emissions. Some states
may require the use of automatic fuel
shut-off containers to reduce fuel
spillage.ContactyourECHOdealerfor
orderinginformation.
After Refueling
• Wipe any spilled fuel from the unit.
• Moveatleast 3 m(10ft.)fromrefueling
location before starting the engine.
After use
• DO NOT store a unit with fuel in its tank.
Leaks can occur. Return unused fuel to an
approved fuel storage container.
Storage - Fuel storage laws vary by
locality. Contact your local government for
the laws affecting your area. As a precau-
tion, store fuel in an approved, air tight
container. Store in a well ventilated, unoccu-
pied building, away from sparks and flames.
Do not store fuel longer than 30 days.
IMPORTANT
Storedfuelages.Donotmixmorefuel
than you expect to use in thirty (30)
days, ninety (90) days when a fuel
stabilizeris added.
IMPORTANT
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thor-
oughly before each use.

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-

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:
• properly 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.

50mm(1or2in.)mediumbristlepaintbrush.
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.

end from the carburetor swivel.
2. Remove the four screws that retain the engine cover. Two at the
top of the starter, two on either side of the front. Lift the cover from
the engine and lay to the front of the hedge clipper.
NOTE
The throttle linkage remains assembled to the engine cover and the

3. Use the wooden stick or brush to remove dirt from the cylinder fins.
4. Remove grass and leaves from the grid between the recoil starter
and fuel tank.
5. Assemble components in reverse order.
NOTE
When installing the engine cover, be certain the tab of the metal

CARBURETORADJUSTMENT
Emission Models (with limiter caps)
Level2.
Tools required: Screwdriver,Tachometer(ECHOP/N99051130017).
Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with 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. Start engine and run for several minutes to reach operating
temperature.
3. 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.
4. Idle Speed Adjustment.
• Start engine and turn “idle” speed adjustment screw (C) CW
until the blades begin to move, then turn the screw CCW until
blades stop moving. Turn screw CCW an additional 1/4 turn.
5. 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.
6. Check HI speed RPM at W.O.T. (Wide Open Throttle). HI speed
RPM should be set to specifications found on page 9 "Specifica-
tions" of this manual.
7. Check idle speed and reset if necessary. If a tachometer is avail-
able, idle speed should be set to the specification found on page 9
"Specifications" of this manual.
