PB-2520 SAFETY

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. T ry to fill each day with jobs where operating the unit or other handheld power equipment is not required.

• If you experience discomfort, redness, and sw elling of the fingers follo wed by whitening and loss of feeling, consult your physician before further exposing yourself to cold and vibration.

ENGLISH

X7501190001 9

SAFETY PB-2520

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 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 emis sions and can cause serious injury or death.

X7501190001 23

OPERATION PB-2520

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 approximatel y 40 hours of oper ation.

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 (A), 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.

5. Additional speed may be necessary to clean debris, snow, etc. from lawns and flowerbeds.

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.

2. Clean the plug or replace with a new one. DO NOT sand blast to clean. Remaining sand will damage engine.

3. Adjust spark plug gap by bending outer electrode.

4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).

PB-2520 MAINTENANCE

Cooling System

Level 2.

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.

ENGLISH

Cleaning Grill

1. Brush accumulated debris from

crankcase intake grill (A) and discharge grill (B).

Carburetor Adjustment

Engine Break-In

New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required.

High Altitude Operation

This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to 335 m (1100 ft.) above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 335 m (1100 ft.) ASL the carburetor may adjusted by an authorized ECHO service dealer.

need to be

If the engine is adjusted for operation above 335 m (1 100 f t.) ASL, the carburetor must be re-adjusted when operating the engine below 335 m (1100 ft.) ASL, otherwise severe engine damage may result.

Level 2.

Note: Every unit is run at the factory and the carburetor is set in

compliance with emission regulations. Carburetor adjustments, other than idle speed, m ust be performed by an authorized ECHO dealer.

Before adjustment make sure that:

• Air filter is clean and properly installed.

• Spark arrestor screen is free of carbon.

• Blower pipes are installed.

PB-2520 TROUBLESHOOTING

1. Start engine, run at idle for one minute.

2. Complete warm up by running at full throttle for 5 minutes, operating

choke twice to clear air from carburetor chambers.

3. Check idle speed and reset if

necessary. If a tachometer is available, idle speed screw (A) should be set to the specifications found on “Specifications” Page of this manual. Turn idle screw (A) clockwise to increase idle speed; counter clockwise to decrease idle speed.

TROUBLESHOOTING

Fuel vapors are extremely flammable and may cause fire an d/or explosion. Never test for ignition spark by grounding spark plug near cylinder plug hole, otherwise serious personal injury may result.
