EB770RT OPERATION Operation of this equipment may create sparks that can start fires around dry vegetation. This unit is equipped with a spark arrestor to prevent discharge of hot particles from the engine. Contact local fire authorities for laws or regulations regarding fire prevention requirements. 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.
OPERATION EB770RT 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. Use of ECHO branded fuel is recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke hybrid engines.
EB770RT ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ OPERATION Use an approved fuel container. DO NOT smoke near fuel. 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.
OPERATION EB770RT After use • Empty the fuel tank prior to storing the unit. 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.
EB770RT 2. Move choke (C) UP to COLD START ( ) position. 3. Pump purge bulb (D) until fuel is visible. Pump bulb an additional 4 or 5 times. 4. Pull recoil starter handle (E) until engine fires, or a maximum of 5 pulls 5. After engine fires (or 5 pulls), move choke lever back to RUN ( ) position, then pull starter handle/rope until engine starts and runs. Allow unit to warm up at idle for several minutes.
OPERATION 2. 3. EB770RT Pump purge bulb (D) until fuel is visible. Pump bulb an additional 4 or 5 times. Pull recoil starter handle (E) and engine should start. Do not use choke (C) Note: If engine does not start after 5 pulls, use cold start procedures. E C D Stopping Engine 1. Throttle Position Lever Release throttle trigger. Move Throttle Position Lever (A) forward to idle position and allow engine to return to idle before shutting off engine. 2.
EB770RT OPERATION 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.
OPERATION EB770RT Note: Never use a higher speed setting than necessary to perform a task. Remember, the higher the engine speed, the louder the blower noise. For Operator Comfort in Cold Weather Operation: This product should not be used in temperatures below 15° F (9° C) otherwise damage to the fuel lines may occur. 1. Remove back cushion (A) from frame. A 2. Install intake cover (B) on frame over air intake. 3. Install back cushion (A) to frame over intake cover.
EB770RT MAINTENANCE MAINTENANCE 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. Allow unit to cool before performing service. Wear gloves to protect hands from sharp edges and hot surfaces.

EB770RT MAINTENANCE 1. Close choke (COLD START( ) position). This prevents dirt from entering the carburetor throat when the air filter is removed. Brush accumulated dirt from air cleaner area. 2. Remove air filter cover, air filter, retainer, and foam pre-filter. Brush dirt from inside cover. Foam Pre-Filter: • Clean foam filter (A) in water/ detergent solution and rinse with clean water. • Wrap the filter in a clean, dry cloth and squeeze (do not wring) dry. Allow to dry completely before reuse.
MAINTENANCE 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. EB770RT 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.
EB770RT 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.
MAINTENANCE 4. EB770RT Clean cylinder fins (A) to allow cooling air to pass freely. 5. Install engine cover. 6. Install air filter cover. 7. Connect spark plug lead. A Exhaust System Spark Arrestor Screen Level 2. Parts Required: Spark Arrestor Screen, Gasket Carbon deposits in muffler will cause a drop in engine output and overheating. Spark arrestor screen must be checked periodically. 1. Disconnect spark plug lead from spark plug 2.
EB770RT 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. MAINTENANCE B A 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.
MAINTENANCE EB770RT If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when operating the engine below 1,100 feet 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, must be performed by an authorized ECHO dealer.
EB770RT TROUBLESHOOTING 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. 4-6 mm C D C TROUBLESHOOTING Fuel vapors are extremely flammable and may cause fire and/or explosion.
