WARNING
The components of this machine generate an electromagnetic field during operation, which can 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 this machine by anyone who has a pacemaker.
Extended Operation and Extreme Conditions

CAUTION
Prolonged exposure to cold and/or vibration can result in injury. Read and follow all safety and operation instructions to minimize risk of injury. Failure to follow instructions can 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.

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.

DANGER
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 can result.

DANGER
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 literature 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.

◆ Always secure the unit during transportation to prevent turnover, fuel spillage, and damage to the unit.

Fuel
WARNING
Diesel fuels and alternative fuels, such as E15 (15% ethanol), E85 (85% ethanol) or any fuels not meeting Shindaiwa requirements are NOT approved for use in Shindaiwa 2-stroke or Hybrid 4-stroke gasoline engines. Use of diesel or 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. Diesel or alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.

Fuel Requirements
Gasoline – Use fresh (purchased within the last 30 days from the pump) 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. Use of ECHO branded fuel is recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.

Two Stroke Oil – A 2-stroke engine oil, such as Shindaiwa branded 2-stroke oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must be used. Shindaiwa branded 2-stroke oils meet these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-LEGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the 2stroke engine warranty.

WARNING
2-Stroke engine oil contains petroleum distillates and other additives that may be harmful if swallowed. Heated oil can release vapors that can cause flash fire, or ignite with explosive force. Read and follow the oil manufacturer’s instructions, and observe all safety warnings and precautions for handling flammable liquids. For more detailed safety and first aid information, visit www.echo-usa.com for a copy of the Material Safety Data Sheet.

◆ KEEP OUT OF REACH OF CHILDREN.

1. Use a clean rag to remove loose dirt from around fuel cap and empty fuel tank.

2. Pull the fuel filter from the tank. NOTICE
   Do not damage fuel line while removing fuel filter from tank.

3. Remove the filter from the line and install the new filter.
   Note: Federal EPA regulations require all model year 2012 and later gasoline powered engines produced for sale in the United States to be equipped with a special low permeation fuel supply hose between the carburetor and fuel tank. When servicing model year 2012 and later equipment, only fuel supply hoses certified by EPA can be used to replace the original equipment supply hose. Fines up to $37,500 may be enforced for using an un-certified replacement part.

Spark Plug
Level 2.
Parts required: Tune-Up Kit

NOTICE
Use only NGK CMR7H spark plug otherwise severe engine damage can occur.

1. Remove spark plug and check for fouling, worn and rounded center electrode.
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 102-153 kgf•cm (86-133 lbf•in).

Cooling System
Level 2.

NOTICE
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.

Clear Debris

1. Brush accumulated debris from intake grill and other cooling passages.

Cleaning Cylinder Fins

1. Disconnect spark plug lead from spark plug.
2. Remove engine cover.
3. Clean cylinder fins (A) to allow cooling air to pass freely.
4. Install engine cover.
5. Connect spark plug lead.

Exhaust System
Spark Arrester Screen
Level 2.
Parts required: Spark Arrester Screen

NOTICE
Carbon deposits in muffler will cause a drop in engine output and overheating. Spark arrester screen must be checked periodically.

1. Disconnect spark plug lead from spark plug.

2. Remove engine cover.

3. Remove spark arrester screen (C) from muffler. Replace screen if plugged with carbon deposits.
   Note: When cleaning carbon deposits, be careful not to damage the catalytic element inside muffler.

4. Install spark arrester screen.

5. Install engine cover.

6. Connect spark plug lead.

Exhaust Port Cleaning
Level 2.
Parts required: Muffler Gasket (as required).

1. Remove spark plug lead from spark plug, and remove engine cover.

2. Place piston at top dead center.
   Remove muffler (A) and muffler gasket (B).

3. Use a wood or plastic scraping tool to clean deposits from cylinder exhaust port. NOTICE
   Never use a metal tool to scrape carbon from the exhaust port. Do not scratch the cylinder or piston when cleaning the exhaust port. Do not allow carbon particles to enter the cylinder.

4. Inspect muffler gasket, and replace if damaged.

5. Install muffler gasket and muffler.

6. Tighten muffler mounting bolts (or nuts) to 110-150 kgf•cm (95-130 lbf•in).

7. Install engine cover and attach spark plug lead.

8. Start engine, and warm to operating temperature.

9. Stop engine, and re-tighten mounting bolts (or nuts) to specifications.

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 (1,100 ft.) above sea level. To maintain proper engine operation and emission compliance above 335 m (1,100 ft.) ASL the carburetor may need to be adjusted by an authorized service dealer.

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

Level 2.
Parts required: None.

Note: Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments, other than idle speed, must be performed by an authorized dealer.

Idle Adjustment
Before adjustment make sure that:

• Air filter is clean and properly installed.
• Spark arrester screen and muffler are free of carbon.
• Blower pipes are installed.

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.

Throttle Cable Adjustment (EB910RT only)
Level 1
If engine idle speed changes when blower pipe is moved, or engine will not reach full wide open throttle speed, adjust throttle cable.

1. Loosen handle adjustment knob (C) and tilt Tube Throttle handle forward to expose Adjustment Screw (D).
2. Turn Adjustment Screw until Throttle Trigger free play is 4 – 6 mm (3/16- 1/4 in.).
3. After adjustment, squeeze and release Throttle Trigger several times to verify Carburetor Throttle Shaft has full range of movement from idle to wide open throttle positions.

TROUBLESHOOTING
