OPERATION SRM-266 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. Metal cutters can also create sparks if the cutter strikes rocks, metal, or other hard objects. Contact local fire authorities for laws or regulations regarding fire prevention requirements. Operation With Blades Blade use DEMANDS specific Brush Cutter configuration.
SRM-266 OPERATION Note: The Barrier Bar is used to restrict rearward movement of the unit. The Barrier Bar is NOT A HANDLE and should not be gripped when using or carrying the unit. Blade Selection The type of Blade used MUST be matched to the type and size of material cut. An improper or dull blade can cause serious personal injury. Blades MUST be sharp. Dull blades increase the chance of kick-out and injury to yourself and bystanders.
OPERATION SRM-266 Use Shoulder/Waist Harness Use of the Shoulder/Waist Harness is recommended for ALL Trimmer/Brush Cutter use, not just Blade operation. The Shoulder/Waist Harness when used in a trimming operation with nylon line head suspends the trimmer from the operator's shoulder and reduces operator fatigue. During blade operation, the same fatigue reduction is achieved.
SRM-266 OPERATION Echo premium Power Blend X™ Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo engines sold in the past regardless of ratio specified in those manuals. Handling Fuel Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result. ◆ 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.
OPERATION SRM-266 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. Leaks can occur. 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.

SRM-266 MAINTENANCE Air Filter Level 1 Parts Required: Tune-Up Kit 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 and air filter retainer from inside cover. Brush dirt from inside cover. 3. Replace filter if it is damaged, very dirty, or the rubber sealing edges are deformed. 4.
MAINTENANCE Parts Required: SRM-266 Tune-Up Kit Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result. 1. Use a clean rag to remove loose dirt from around fuel cap and empty fuel tank. 2. Pull the fuel filter from the fuel tank. 3. Remove the filter from the line and install the new filter.
SRM-266 MAINTENANCE 3. Adjust spark plug gap by bending outer electrode. 4. Tighten spark plug to 150–170 kgf • cm (130–150 in • lbf). Cooling System Level 2 Parts Required: None if you are careful. 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.
MAINTENANCE SRM-266 DO NOT use a metal scraper to remove dirt from the cylinder fins. 5. Use brush to remove dirt from the cylinder fins. 6. Remove grass and leaves from the grid between the recoil starter and fuel tank. 7. Assemble components in reverse order. Exhaust System Spark Arrestor Screen Level 2 Parts Required: Spark Arrestor Screen, Gasket 1. Remove spark plug lead. 2. Remove muffler cover (A). 3. Place piston at Top Dead Center (TDC) to prevent carbon/dirt from entering cylinder.
SRM-266 1. Remove spark plug lead from spark plug, and remove engine cover. 2. Place piston at top dead center. Remove muffler (A) and heat shield (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 heat shield, and replace if damaged. 5.
MAINTENANCE SRM-266 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. 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 ECHO dealer. 1. Check idle speed and reset if necessary.
SRM-266 MAINTENANCE Gear Housing 1. Clean all loose debris from gear case. 2. Remove plug (A) and check level of grease. 3. Add grease if necessary. DO NOT over-fill. Drive Shaft (flex cable models) B C 1. Loosen two (2) screws (B) and remove center locating screw (C). Pull gear case and shield from drive shaft housing. 2. Pull flexible cable from the drive shaft housing, wipe clean and re-coat with a thin coating (15 ml [1/2 oz.]) of grease. 3.
MAINTENANCE SRM-266 Nylon Line Replacement Wear Gloves or personal injury may result: ◆ Cutoff knife is sharp. ◆ Gearcase and surrounding area may be hot. 1. Cut one piece of line to recommended length. 2.0 mm (.080) diam. – 6 m (20 ft.) 2.4 mm (.095) diam. – 6 m (20 ft.) 2. Align arrows on top of knob with openings in eyelets. 3. Insert one end of trimmer line into an eyelet, and push line equal distance through trimmer head. 4.
SRM-266 MAINTENANCE When the wear indicators located at the bottom of the SpeedFeed® head are worn smooth, or if holes appear, replacement of the cover or the entire SpeedFeed® head is required. Wear Indicators Sharpening Metal Blades Several styles of metal blades are approved for use on the Brush Cutter. The 8-tooth blade can be sharpened during normal maintenance. The clearing blade and 80 tooth blade require professional service.
TROUBLESHOOTING SRM-266 If an electric grinder is used, use care not to overheat teeth, do not allow tips/tooth to glow red or turn blue. DO NOT place blade in cooling water. This will change the temper of the blade and could result in blade failure. 3. After sharpening teeth, check each tooth radius for evidence of a square (sharp) corner. Use the round (rat tail) file to renew the radius.
