• 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.
After Refueling;
• Wipe any spilled fuel from the unit.
• Move at least 3M (10 ft.) from refueling location before starting.
3M
(10 ft.) MINIMUM
After Use;
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return
unused fuel to an approved fuel storage container.
PERSONAL CONDITION AND SAFETY EQUIPMENT
W ARNING DANGER
Hedge Clipper users risk injury to themselves and others if the shaft hedge clipper is used improperly and or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating a shaft hedge clipper.
Physical Condition
Your judgment and physical dexterity may not be good:
• if you are tired or 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 meeting ANSI Z87.1 of CE requirements whenever
you operate the unit.
Face and Head Protection
When trimming overhead, wear head protection meeting ANSI Z89.1 or
CE requirements with a full face shield. Head protection with full face
shield will help protect you from falling debris.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your grip on the Shaft
Hedge Clipper handles. Gloves also reduce the transmission of machine
vibration to your hands.
Hearing Protection
ECHO recommends wearing hearing protection whenever unit is used.

SAFE OPERA TION
Determine Operation Area
• Provide all operators of this equipment with the Operator's Manuals
and instructions for safe operation.
• Review the area to be trimmed. Look for hazards that could contribute
to unsafe conditions. DO NOT operate unit if any wires (power,
telephone, cable, etc.) are closer than 4.5 M (15 ft.) to any part of the
operator or unit.
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 M (50 ft.) while the
Hedge Clipper is in use.
Operation
Use Proper Clothing & Equipment
• Before starting the unit, equip yourself and any other person
working within the 15 M (50 ft.) Safety Zone with the required
Protective Equipment and clothing.
15 M
(50 FT.)
W ARNING DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can
cause serious injury or death.
Avoid Hot Surfaces
• During operation, the complete unit, especially the drive shaft
housing, power head, muffler area and gear box may become very
hot, too hot to touch. Avoid contact during and immediately after
operation.
Keep A Firm Grip
• Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles
Keep A Solid Stance
• Maintain footing and balance at all times. Do not stand on
slippery, uneven or unstable surfaces. Do not work in odd
positions or on ladders. Do not over reach.
Operation (HCA)
• Never adjust blade angle of HCA while standing.
• Only adjust cutting angle with HCA resting flat on the ground, with
the engine stop switch in the "STOP" position.
• Adjust cutting angle by moving locking lever (A) up. Depress blade
indexing lever (B) and change blade angle with rear cutter assembly
handle. Release indexing lever (B) into notch. Move locking lever (A)
down to completely engage internal gears.
IMPORTANT
Lever (A) does not secure gearbox angle setting. Moving lever in
the down position reduces internal play in the gear box. Do not
over tighten castle nut (C) to insure gear box angle setting
tightness because damage to internal gears will occur. If the lever
is loose or very tight adjust nut (C) for snug 90° movement.

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.
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 and force with 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.
