SAFETY PB-2620 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.

If loosening occurs, remove pipe, and reinstall according to instructions 3 and 4. Remove Blower Pipes 1. Insert screwdriver into hole (G) to release pipe lock. G 2. Pull pipe out of fan case. 3. Remove screwdriver. OPERATION Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all openings.
OPERATION PB-2620 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.
PB-2620 OPERATION 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.
OPERATION ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ PB-2620 Use an approved fuel container. Mark fuel containers as containing 2-stroke mixture fuel. 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.
PB-2620 OPERATION • 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. Do not mix more fuel than you expect to use in 30 days, 90 days when a fuel stabilizer is added.
OPERATION PB-2620 Starting Cold Engine 1. Stop Switch Move stop switch (A) away from the STOP position. 2. B Throttle Position Lever A Move throttle position lever (B) midway between idle and full throttle positions. 3. Choke Move choke (C) to COLD START ( ) (closed) position. 4. Purge Bulb Pump purge bulb (D) until fuel is visible and flows freely in the clear fuel tank return line. C D Recoil starter: Use short pulls - only 1/2 to 2/3 of rope for starting.
PB-2620 5. Recoil Starter Place the unit on a flat, clear area. Firmly grasp throttle handle (E) with left hand and rapidly pull recoil starter handle (F) until engine fires, or maximum 5 pulls. 6. OPERATION Choke E F Move choke lever (C) to RUN position ( ), and if necessary, restart engine. Note: If engine does not start with choke in RUN position after 5 pulls, repeat instructions 3 - 6. 7.
OPERATION 3. PB-2620 Purge Bulb Pump purge bulb (C) until fuel is visible and flows freely in the clear fuel tank return line. C 4. Recoil Starter Place the unit on a flat, clear area. Firmly grasp throttle handle (D) with left hand and rapidly pull recoil starter handle/ rope (E) until engine fires. D E Recoil starter: Use short pulls - only 1/2 to 2/3 of rope for starting. Do not allow the rope to snap back in. Always hold the unit firmly.
PB-2620 OPERATION Stopping Engine 1. Throttle Trigger/Throttle Position Lever B Release throttle trigger (A). Move throttle position lever (B) forward to idle position and allow engine to return to idle before shutting off engine. C A 2. Stop Switch Move stop switch (C) to STOP position. If engine does not stop when stop switch is moved to STOP position, close choke - COLD START position - to stall engine. Have your dealer repair stop switch before using unit again.
OPERATION PB-2620 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.
PB-2620 MAINTENANCE 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 away from all openings.

PB-2620 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. Brush dirt from inside cover. 3. Remove air filter and lightly brush debris from filter. Replace filter if it is damaged, fuel soaked, very dirty, or the rubber sealing edges are deformed. Clean the filter with a neutral detergent. Do not use solvents for cleaning. 4.
MAINTENANCE PB-2620 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.
PB-2620 MAINTENANCE 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. Cleaning Grill 1.
MAINTENANCE PB-2620 Cleaning Cylinder Fins Blow compressed air through crankcase intake grill and discharge grill at area shown. Exhaust System See your dealer for maintenance. 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.
PB-2620 MAINTENANCE 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. X7501190601 © 11/2018 ECHO Inc.
