EQUIPMENT
WARNING DANGER
Use only ECHO approved attachments. Serious injury may result from the use of a non-approved attachment combi-
nation. ECHO, INC. will not be responsible for the failure of cutting devices, attachments, or accessories which have
not been tested and approved by ECHO. Read and comply with all safety instructions listed in this manual and safety
manual.
• 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.
• Inspect hand guard for damage. Replace if damaged or missing.
• Check that the blade assembly is firmly attached and in safe operating
condition. Dull, loose or damaged blades should not be used.
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,becausetheminimumexposure, which might trigger the
ailment,isunknown.
• 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 unit 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 expo-
sure 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.
• Takeperiodicbreakstominimizerepeti-
tion and rest your hands.
• Reduce the speed and force with which
you do the repetitive movement.
• Do exercise 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.

IMPORTANT
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.
AfterRefueling
• Wipe any spilled fuel from the unit.
• Moveat least 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 precaution, store
fuel in an approved, airtight container. Store
in a well-ventilated, unoccupied building,
away from sparks and flames. Do not store
fuel longer than 30 days.
IMPORTANT
Storedfuelages.Do not mix more fuel
than you expect to use in thirty (30)
days, ninety (90) days when a fuel

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 in the crankcase 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 crankcase cooling passage blockages or cleaning of
cooling fins is considered “Normal Maintenance.” Any failure attrib-
uted to lack of maintenance is not warranted.
1. Remove spark plug lead and spark plug.
2. Remove (4) starter cover hex socket bolts and starter.
Tools required: T-wrench, Feeler gauge, Soft metal brush

4. Remove heat shieldbolt(C)fromthemufflercover.
5. Carefully pull cylinder cover forward disengagingmufflergasket
tabs and ignition lead and lay aside.
6. Loosely install spark plug to keep debris out of the cylinder. Use
brush to remove dirt from cylinder fins.
IMPORTANT
DO NOT use a metal scraper to remove dirt from the cylinder fins.
7. Assemble components in reverse order.
NOTE
When installing the cylinder cover, be certain the muffler gasket
tabs (D) are locked into the muffler grill slots and the stop switch
lead is seated in the rubber grommet.
Cylinder Exhaust Port
Level3.
IMPORTANT
The cylinder exhaust port must be inspected and cleaned of excess
carbon every 3 months or 90 hours of operation in order to maintain
this engine within the emissions durability period. ECHO strongly
recommends that you return your unit to your ECHO dealer for this
importantmaintenance service.
3. Remove bottom right (A) and bottom left (B) hex socket bolts from

CARBURETORADJUSTMENT
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-
in period your engine performance will increase and exhaust emissions
will stabilize. Idle speed can be adjusted as required.
High Altitude Adjustment
High altitude adjustment is not required for proper operation of this
engine.
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. This carburetor does not have
acceleration and high-speed adjustment needles.
1. Check idle speed and reset if necessary. If a tachometer is available,
idle speed screw (A) should be set to the specifications found on
page 9 “Specifications” of this manual. Turn idle screw (A) clock-
wise to increase idle speed; counter clockwise to decrease idle
speed.
WARNING DANGER
When carburetor adjustment is completed, the cutting attachment
should not move at idle, otherwise serious personal injury may
result.

Level1.
Tools required: Cleanrag,25or 50 mm(1or2in.)cleaningbrush
Parts required: 20WEngineOil(lubrication),50-50mixtureof
kerosene and 20W oil (cleaning).
WARNING DANGER
Hedge Clipper Blades are very sharp. Wear gloves to protect
hands.
1. Disconnect spark plug wire from spark plug.
2. Brush loose debris from blade and coat both sides of blade with the
50-50cleaningmixture.
3. Allow cleaning mixture to soften the remaining gummy residue then
wipeitfromtheblade.
4. Apply clean oil to the entire length of the blade. Be certain the
blade bolts are lubricated.
5. Wipe excess oil from the blade before putting the unit back in
service.

Level1.
Tools required: GreaseGun,Cleanrag
Parts required: ECHO®LUBETM 14oz.(P/N91015)orLithiumBased
Grease.
1. Clean dirt fromthegrease fitting (A).
2. Carefully pump grease into fitting (A). DO NOT force grease. Too
much pressure will force grease past seals and cause damage.
Apply 1-2 pumps of grease every 15-25 hours of operation.
3. Wipe excess grease from around grease fitting.
