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.

Hand Protection

Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your hands.

Hearing/Ear Protection

ECHO recommends wearing hearing protection whenever unit is used.

Breathing Protection

Operators who are sensitive to dust or other common airborne allergens may need to wear a dust mask to prevent inhaling these materials while operating unit. Dust masks can provide protection against dust, plant debris, and other plant matter such as pollen. Make sure the mask does not impair your vision, and replace the mask as needed to prevent air restrictions.

Proper Clothing

Wear snug-fitting, durable clothing:

• Pants should have long legs, shirts should have long sleeves.

• DO NOT WEAR SHORTS.

• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or hanging items that could become entangled in moving parts or surrounding growth.

The components of this machine generat e an electromagnetic field during operation, which may interfere with some pacemakers. To reduce the risk of serious or fata l injury, persons with pacemakers should consult with their physician and the pa cemaker manufacturer before operating this machine. In the absence of such information, ECHO does not recommend machine 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.

the use of this

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.

PB-755S H/T SAFETY

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 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.

All over head electrical conductors and communicat ions 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.

◆ 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 3 m (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.

PB-755S H/T OPERATION

PB-755S H

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 oper ation may allow fuel/oil residue to build-up on the piston and cause rapid build-up of carbon on the spark ar restor screen, resulting in overheating and engine damage. T o 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. PB-755S H

Set engine speed with throttle lever (A).

MAINTENANCE PB-755S H/T

PB-755S T

Control engine speed with throttle trigger (C), or throttle position lever (A). Rotate throttle position lever forward for lower speed, back for higher speed.

4. Use lower speed to blow dry

leaves from walks, patios and drives.

5. Additional speed may be necessary to clean grass and leaves from a lawn

or flower bed.

6. Higher speed may be necessary to move gravel, dirt, snow, bottles or cans

from a driveway, street, parking lot or stadium.

7. Always stop unit using stop engine procedure.

Note: Never use a higher speed setting than

necessary to perform a task. Remember, the higher the engine speed, the louder the blower noise. Minimize dust by using blower at lower speeds. Keep debris on your property. Be Smart - be a good neighbor.

MAINTENANCE

Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects a way from all o penings. 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. Allow unit to cool before performing service. Wear gloves to protect hands from sharp edges and hot surfaces.

Your ECHO unit is designed to provide many hours of trouble free service. Regular scheduled maintenance will help your unit achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take your unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have the ECHO Dealer do it, each maintenance task has been graded. If the task is not listed, see your ECHO Dealer for repairs.

Skill Levels

Level 1 = Easy to do. Common tools may be required. Level 2 = Moderate difficulty. Some specialized tools may be required.
