FUEL
WARNING 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
outdoors 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
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.
3 M (10 ft.)
After Refueling;
• Wipe any spilled fuel from the unit.
• Move at least 3 M (10 ft.) from refueling location before starting.

PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
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.
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.
SAFE OPERATION
Determine Operation Area
- Provide all operators of this equipment with the Operator's Manual
and instructions for safe operation.
- Review the area to be tilled. 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 15M (50 ft.) while the
tiller/cultivator is in use.
- Do not operate this product indoors or in inadequately ventilated
areas.
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.
TILLER/CULTIVATOR
OPERATOR'S MANUAL
15M (50 ft.)
7
• 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. 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.

PRE-OPERATION
FUEL
Fuel Requirements
Gasoline - Use 89 Octane [ ] gasoline or gasohol known to be good
quality. Gasohol may contain up to 10% Ethyl (grain) alcohol or 15%
MTBE (methyl tertiary-butyl ether). Gasohol containing methanol
(wood alcohol) is NOT approved.
Two-Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD
Standard (ISO/CD 13738), must be used. Echo brand Premium 50:1 oil
meets this standard. Engine problems due to inadequate lubrication
caused by failure to use an ISO-L-EGD approved 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 EPA Phase I/
California Emission Defect Warranty Explanation.)
Mixing - Follow directions on the oil container.

(0.026 in.)
COOLING SYSTEM CLEANING
Level 3.
Tools required: Cross Head Screwdriver, 3mm Hex wrench, Pointed
Wood Stick, 25mm-50mm (1in.-2in.) 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.
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. Remove spark plug lead and throttle cable end from the carburetor
swivel.
2. Remove the four screws that retain the cover. Two at the top of the
recoil starter, two on either side of the front. Lift the cover from the
engine and lay to the front of the tiller/cultivator.
NOTE
The throttle linkage remains assembled to the cover and the spark
plug lead and grommet remain installed.
IMPORTANT
DO NOT use a metal scraper to remove dirt from the cylinder fins.
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. When installing the cover, be certain the tab of the metal deflector
shield is in the slot of the cover.
