OPERATION PB-250LN Fuel Alternative fuels, such as E-15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO requirements are NOT approved for use in ECHO 2-stroke gasoline engines. Use of 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. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
PB-250LN OPERATION Mixing Instructions 1. Fill an approved fuel container with half of the required amount of gasoline. 2. Add the proper amount of 2-stroke oil to gasoline. 3. Close container and shake to mix oil with gasoline. 4. Add remaining gasoline, close fuel container, and remix. Spilled fuel is a leading cause of hydrocarbon emissions. Some states may require the use of automatic fuel shut-off containers to reduce fuel spillage. After use • DO NOT store a unit with fuel in its tank.
OPERATION PB-250LN 4. Purge Bulb Pump purge bulb (D) until fuel is visible and flows freely in the clear fuel tank return line. Recoil starter: Use short pulls - only 1/2 ~ 2/3 of rope for starting. Do not allow the rope to snap back in. Always hold the unit firmly. D C 5. Recoil Starter Place the unit on a flat, clear area. Firmly grasp throttle grip with left hand and rapidly pull recoil starter handle/rope (E) until engine fires , or maximum 5 pulls. E 6.
PB-250LN OPERATION 4. Recoil Starter Place the unit on a flat, clear area. Firmly grasp throttle grip with left hand and rapidly pull recoil starter handle/rope (E) until engine fires. E Recoil starter: Use short pulls - only 1/2 ~ 2/3 of rope for starting. Do not allow the rope to snap back in. Always hold the unit firmly. Note: If engine does not start after 5 pulls, use Cold Start Procedure. Stopping Engine 1. Throttle Trigger/Throttle Position Lever Release throttle trigger (F).
OPERATION PB-250LN 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-250LN 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. Your ECHO unit is designed to provide many hours of trouble free service.

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 150-170 kgf • cm (130-150 in • lbf).
MAINTENANCE PB-250LN Cleaning Cylinder Fins 1. Remove spark plug lead from spark plug, and remove engine cover. 2. Clean cylinder fins to allow cooling air to pass freely. 3. Reassemble parts in reverse order. 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. Remove spark plug lead from spark plug, and remove engine cover. 2.
PB-250LN MAINTENANCE 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 heat shield, and replace if damaged. 5. Install heat shield and muffler. 6. Tighten muffler mounting bolts (or nuts) to 60-70 in•lbf (70-80 kgf•cm). 7. Loosely reassemble engine cover. 8. Tighten all screws securely. 9. Attach spark plug lead. 10.
MAINTENANCE PB-250LN 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.
