Personal Condition and Safety Equipment
Users of this product risk injury to themselves and others if the unit is used improperly and/or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating unit.
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
•Eye protection that meets ANSI Z87.1 or CE requirements must be worn whenever you operate the
unit.
•For additional safety, a full-face shield may be worn over safety glasses or goggles to provide
protection from sharp branches or flying debris.

©10/2014 ECHO Inc.
• DO NOT OPERATE UNIT BAREFOOTED.
Keep long hair away from engine and air intake. Retain hair with cap or net.
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.
The components of this machine generate an electromagnetic field during operation, which may
interfere with some pacemakers.To reduce the risk of serious or fatal injury, persons with
pacemakers should consult with their physician and the pacemaker manufacturer before operating
this machine.In the absence of such information, ECHO does not recommend the use of ECHO
products by anyone who has a pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in injury. Read and follow all safety and
operation instructions to minimize risk of injury. Failure to follow instructions may result in painful
wrist/hand/arm injuries.
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 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.

SAFETY PB-255LN
Repetitive Stress Injuries (RSI)
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 exercise 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.
All over head electrical conductors and communications wires can have electricity flow with high
voltages. This unit is not insulated against electrical current. Never touch wires directly or indirectly,
otherwise serious injury or death may result.
Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains
poisonous emissions and can cause serious injury or death.
Read the Manual
• Provide all users of this equipment with the Operator’s Manual for instructions on Safe Operation.
Clear the Work Area
• Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets
outside a 15 m (50 ft) radius; outside the 15 m (50 ft) zone, there is still a risk of injury from thrown objects.
Bystanders should be encouraged to wear eye protection. If you are approached, stop the engine.
• Avoid blowing debris towards people, pets, open windows, or vehicles when using unit.
• Review area to be cleared. Look for potential hazards such as stones or metal objects.
Keep a Firm Grip
• Hold the handle in one hand, with thumb and fingers encircling the handle.

PB-255LN SAFETY

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.
Avoid Hot Surfaces
• Keep exhaust area clear of flammable debris. Avoid contact
during and immediately after operation.

OPERATION PB-255LN
OPERATION
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects
away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts
have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Blower housing may contain shredder blades and other sharp edges that can cause serious injuries
if touched, even if engine is off and blades are not moving. Wear gloves to protect hands from sharp
edges and hot surfaces.
Operation of this equipment may create sparks that can start fires. This unit is equipped with a spark
arrestor to prevent discharge of hot particles from the engine. Metal cutters can also create sparks if
the cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or
regulations regarding fire prevention requirements.
Fuel
Alternative fuels, such as E-15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO
requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels
may cause performance problems, loss of power, overheating, fuel vapor lock, and unintended
machine operation, including, but not limited to, improper clutch engagement. Alternative fuels may
also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may
contain up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing
methanol (wood alcohol) is NOT approved. ECHO brand Power Fuel™is 93 octane, ethanol-free fuel
premixed with ECHO Red Armor®engine oil at 50:1 ratio. Use of ECHO Power Fuel™is recommended to
extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards
must be used. Echo brand premium Power Blend X™Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and
J.A.S.O. FD certified oil, such as Echo premium Power Blend X™, will void the two-stroke engine warranty.
Echo premium Power Blend X™Universal 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.
Handling Fuel
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.

PB-255LN OPERATION
X7501186400 17
©10/2014 ECHO Inc.
•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 or RUNNING!
•DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
•DO NOT overfill fuel tank. Wipe up spills immediately.
•Securely tighten fuel tank cap and close fuel container after refueling.
•Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is
repaired.
•Move at least 3m (10 ft.) from refueling location before starting the engine.
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. Add remaining gasoline, close fuel container, and remix.
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.
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.
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.
Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use.

OPERATION PB-255LN
Operating Blower
Engine exhaust IS HOT, and contains Carbon Monoxide
(CO), a poison gas. Breathing CO can cause
unconsciousness, serious injury, or death. Exhaust can
cause serious burns. ALWAYS position unit so that
exhaust is directed away from your face and body.
Always wear safety glasses, hearing protection and a face
filter mask or serious personal injury may result. Do not
point the blower pipe in the direction of people or pets.
Use reduced speed only when performing light-duty tasks or to
comply with local noise regulations. Continuous low speed
operation may allow fuel/oil residue to build-up on the piston
and cause rapid build-up of carbon on the spark arrestor
screen, resulting in overheating and engine damage. To reduce
harmful build-up, run engine at wide open throttle for at least 5
minutes every hour, and inspect/clean the spark arrestor screen
after approximately 40 hours of operation.
Read the Safety Section carefully.
To avoid engine damage due to over-revving, do not block
blower pipe.
1. Use only during appropriate hours.
2. Allow the engine to warm up at a fast idle for a few minutes.
3. Control engine speed with throttle trigger (F), or for
continuous use, set engine speed with throttle position lever
(B). Rotate throttle position lever forward for lower speed, back for higher speed.
4. Use lower speed to blow debris from hard surfaces.
