SAFETY INSTRUCTION
PERSONAL
Tiller/Cultivator users risk injury to themselves and others if the tiller/cultivator is used improperly and or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating a tiller/cultivator. Failure
to do so can result in serious injury.
Physical Condition --
Your judgment and physical dexterity may not be good:
- if you are 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 meet ANSI Z87.1 or CE requirements whenever you operate the tiller/cultivator.
Hand Protection --
Wear no-slip, heavy duty work gloves in improve your
grip on the Tiller/Cultivator handles. Gloves also reduce
the transmission of machine vibration to your hands.
Hearing Protection --
ECHO recommends wearing hearing protection whenever
unit is used.
CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
Proper Clothing --
Wear snug fitting, durable clothing;
- Pants should have long legs, shirts with long sleeves.
- Wear hair covering to contain long hair.
- DO NOT WEAR SHORTS,
- DO NOT WEAR TIES, SCARFS, JEWELRY.
Wear sturdy work shoes with non-skid soles;
- DO NOT WEAR OPEN TOED SHOES,
- DO NOT OPERATE UNIT BAREFOOTED.
Wear no-slip, heavy duty work gloves.
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.
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.
TILLER/CULTIVATOR
OPERATOR'S MANUAL
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.
5
EQUIPMENT
Before operation a complete check of the unit must be performed;
• 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 shield for damage and ensure that the shield is securely in
place. Replace if shield is damaged or missing.
• Check that the tines are firmly attached and in safe operating condition.
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.

FUEL
Fuel Requirements
TILLER/CULTIVATOR
OPERATOR'S MANUAL
11
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known
to be good quality. Gasoline may contain up to 15% MTBE (methyl
tertiary-butyl ether). Gasohol containing methyl (wood) alcohol is NOT
approved.
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD
13738) and J.A.S.O. FC Standards, must be used. Echo brand Premium
50:1 oil meets these standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-L-EGD and J.A.S.O. FC
certified oil, such as Echo Premium 50:1 Two-stroke Oil, 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
Echo Premium 2-Stroke Oil may be mixed 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 proper amount of 2-stroke oil to gasoline.
3 . Close container and shake to mix oil with gasoline.
4 . Add remaining gasoline and remix.
5 . Install fuel container cap and wipe any spilled fuel from container
and surrounding area.
Handling Fuel
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 your ECHO dealer
for ordering information.
After Refueling;
• Wipe any spilled fuel from the unit.
• Move at least 3 m (10 ft.) from refueling
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, air tight container. Store in a well
ventilated, unoccupied building, away from
sparks and flames. Do not store fuel longer
than 30 days.
IMPORTANT
Stored fuel ages. Do not mix more fuel
than you expect to use in thirty (30)
days, ninety (90) days when a fuel
stabilizer is added.
W ARNING DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing or
handling, or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow flames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps
slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT!
• NEVER refuel a unit with the engine running.
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks out
doors over bare ground.
• Securely tighten fuel cap after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or
operate unit until leakage is repaired.
IMPORTANT
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thoroughly before each use.

TILLING/CULTIVATING
W ARNING DANGER
Do not operate this unit indoors or in inadequately ventilated
areas.
• Carry unit to tilling/cultivating area using plastic carry handle and
upper handle. Avoid contact with tines or hot engine parts.
• Check the area to be tilled or cultivated. Look for any hazards and
obstructions that could contribute to unsafe conditions.
• Remove all rocks, debris, and other materials that could become
jammed in the tines.
• Do not till or cultivate in areas where there may be hidden hazards,
such as sprinkler heads and pipes, buried power cables or gas lines,
or other similar hazards.
• Start the unit as shown in “Starting” instructions.
• Hold unit securely, using both hands to grip hand grips.
• Depress throttle trigger gradually to begin operation.
• Release throttle trigger to stop tines.
• Allow engine to return to idle, and move switch to “Stop” position to
stop engine.
TILLING – Recommended tilling depth is 6 – 8 inches
Install Tines with individual tines angled forward, toward front of unit.
(See Tine Removal/Cleaning/Installation, page 20)
• Use a forward/backward motion to till soil. Allow tines to dig into
soil, then pull unit back to break up and pulverize clumps. Tilling
depth is controlled by the number of times the forward/backward
motion is used in an area.
• Controlling tilling depth :
• Shallow tilling: Move tiller over soil surface quickly. Tines should be
in cultivating position.
• Deeper tilling: Move tiller over soil slowly. Allow tiller to work the
same area until desired depth is reached.
• Big Weeds/Tough Roots: Rock tiller back and forth over tough spot
until the tines slice through the roots or weeds.
• Digging Holes: Hold tiller in place, and allow tines to dig down into
the soil. Allow tines to dig approximately 6 – 8 inches deep, then lift
unit up and out. Remove loose soil with shovel or rake. Resume
digging with rotating tiller tines until desired depth is reached.
CULTIVATING – Recommended cultivating depth is 2 – 3 inches
Install Tines with individual tines angled rearward, toward the operator.
(See Tine Removal/Cleaning/Installation, page 20)
Allow unit to move forward slowly. Pull unit back to cut vegetation and
cultivate soil to desired depth. Repeat forward/backward motion as
needed.

COOLING SYSTEM CLEANING
Level 2.
Tools required: Cross Head Screwdriver, 3mm Hex wrench, Pointed
Wood Stick, 25-50mm (1-2 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.
0.65 mm
(0.026 in.)
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. Disconnect spark plug lead. Remove spark plug and throttle cable
end from the carburetor swivel.
2 . Remove four screws from starter cover, lift the cover from the
engine and lay to the side.
