SAFETY PB-2620 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.
PB-2620 SAFETY • 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.
SAFETY PB-2620 Avoid Hot Surfaces • Keep exhaust area clear of flammable debris. Avoid contact during and immediately after operation. Equipment Use only approved attachments. Serious injury may result from the use of a non-approved attachment combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments or accessories which have not been tested and approved by ECHO.

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 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. • Empty the fuel tank prior to storing the unit. Return unused fuel to an approved fuel storage container. 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 4. MAINTENANCE 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. 5. Use lower speed to blow debris from hard surfaces. 6. Additional speed may be necessary to clean debris, snow, etc. from lawns and flowerbeds. B A Note: Never use a higher speed setting than necessary to perform a task.
MAINTENANCE PB-2620 Your 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, we recommend that you take your unit to a Servicing Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have the Dealer do it, each maintenance task has been graded. If the task is not listed, see your Dealer for repairs.
