SAFETYINSTRUCTIONS
PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
Pro Attachment SeriesTM users risk injury to themselves and others if the Pro Attachment SeriesTM unit is used
improperly and or safety precautions are not followed. Proper clothing and safety gear must be worn when operating
a Pro Attachment SeriesTM unit.
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,becausethe minimum exposure whichmighttrigger the
ailmentisunknown.
• 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).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.
• Takeperiodicbreakstominimizerepeti-
tion 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
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
likelypermanent nerve and muscle
damage can be prevented.
Physical Condition
Your judgment and physical dexterity may not be good:
• if you are tired or sick,
• ifyou aretaking medication,
• if you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Eye Protection
EyeprotectionthatmeetANSIZ87.1orCE requirements
must be worn whenever you operate the unit.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the handles. Gloves also reduce the transmission
of machine vibration to your hands.
Hearing Protection
Wearhearingprotection.ECHOrecommendswearing
hearing protection whenever unit is used.
Proper Clothing
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DONOTWEARSHORTS,
• DONOTWEARTIES,SCARFS,JEWELRY.
Wear protective hair covering to contain long hair.
Wear sturdy work shoes with nonskid soles;
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
Wear no-slip, heavy duty work gloves.

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.Contact yourECHOdealerfor
orderinginformation.
After Refueling
• Wipe any spilled fuel from the unit.
• Moveatleast3m (10 ft.) fromrefueling
location before starting.
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, air tight container. Store in a well
ventilated, unoccupied building, away from
sparks and flames. Do not store fuel longer
than 30 days.
IMPORTANT
Storedfuel ages. Donot mix morefuel
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.
PRE - OPERATION
FUEL
Fuel Requirements
Gasoline-Use 89 Octane[R+M/2](mid grade orhigher)gasoline known
to be good quality. Gasoline may contain up to 15% MTBE (methyl
tertiary-butylether). Gasohol containingmethyl (wood) alcohol is NOT
approved.
TwoStrokeOil-Atwo-strokeengineoilmeetingISO-L-EGD(ISO/CD
13738)and J.A.S.O. FC Standards must be used. Echo brand premium
Power Blend TM Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an ISO-
L-EGDandJ.A.S.O.FCcertifiedoil,suchasEchopremiumPowerBlend
TM, will void the two-stroke engine warranty. (Emission related parts
only are covered for two years, regardless of two-stroke oil used, per
the statement listed in the Emission Defect Warranty Explanation.)
IMPORTANT
EchopremiumPowerBlendTM Universal2-StrokeOilmaybemixed
at 50:1 ratio for application in all Echo engines sold in the past
regardless of ratio specified in those manuals.
Mixing Instructions
1. Fill an approved fuel container with half of the required amount
of gasoline.
2. Add the proper amount of 2-stroke oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Addremaininggasolineandremix.
5. Install fuel container cap and wipe any spilled fuel from container
and surrounding area.
Handling Fuel
WARNING DANGER

4. Recoil Starter
Lay the unit on a flat area and keep movable attachment parts clear
of all obstacles. Firmly grasp right hand grip and throttle trigger
lockout with left hand and fully depress throttle trigger to wide open
position. Rapidly pull recoil starter handle/rope (D) until engine fires
(ormaximumfive[5]pulls).
5. Choke
After engine fires (or five [5] pulls), move choke lever back to Run
() position. Hold throttle trigger and throttle trigger lockout fully
depressed and pull recoil starter handle/rope until engine starts and
runs. Release throttle trigger and allow unit to warm up at idle for
several minutes.
NOTE
If engine does not start with choke in “RUN” position after 5 pulls,
repeat instructions.

Lay the unit on a flat area and keep movable attachment parts clear
of all obstacles. Rapidly pull recoil starter handle/rope (D) until
enginefires.
NOTE
If engine does not start after 5 pulls, use Cold Start Procedure.
STOPPING ENGINE
1. Throttle
Release throttle and allow engine to return to idle before shutting off
engine.
2. Stop Switch
Move stop switch button/lever (A) to STOP position.
WARNING DANGER
If engine does not stop when stop switch is moved to STOP
position, close choke - COLD START position - to stall engine.
Have your ECHO dealer repair stop switch before using unit again.

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.

Level2.
Tools required: 25or50mm(1or2in.)mediumbristlepaintbrush,
Cross-HeadScrewdriver,4mmHexWrench
Parts Required: None if you are careful.
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.
