SAFETY SRM-2620U Personal Condition and Safety Equipment Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions are not followed. Proper clothing and safety gear must be worn when operating unit. Physical Condition Your judgment and physical dexterity may not be good: • If you are tired or sick. • If you are taking medication. • If you have taken alcohol or drugs. Operate unit only if you are physically and mentally well.
SRM-2620U SAFETY Hand Protection Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your hands. ENGLISH Hearing/Ear Protection ECHO recommends wearing hearing protection whenever unit is used.
SAFETY SRM-2620U The components of this machine generate an electromagnetic field during operation, which may interfere with some pacemakers. To reduce the risk of serious or fatal injury, persons with pacemakers should consult with their physician and the pacemaker manufacturer before operating this machine. In the absence of such information, ECHO does not recommend the use of this machine by anyone who has a pacemaker.
SRM-2620U SAFETY Repetitive Stress Injuries (RSI) ENGLISH 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.

Remove air filter cover. Brush dirt from inside cover. 3. ENGLISH Assure throttle wire retaining clip remains in place as shown when removing or installing air filter cover.
MAINTENANCE SRM-2620U Assure air filter is assembled with pleats oriented vertically. Fuel Filter Level 1. Parts Required: 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. Do not damage fuel line while removing fuel filter from tank. 3.
SRM-2620U MAINTENANCE Spark Plug Level 2. Parts Required: Tune Up Kit. Use only NGK CMR7H spark plug otherwise severe engine damage may occur. 1. 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.

MAINTENANCE SRM-2620U 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. 1. Remove spark plug lead. 2. Remove muffler cover (A). 3.
SRM-2620U MAINTENANCE Remove spark plug lead. 2. Remove muffler cover (B). 3. Place piston at Top Dead Center (TDC) to prevent carbon/dirt from entering cylinder. 4. Remove spark arrestor screen cover (C), gasket (E), and screen (F), from muffler body. 5. Clean carbon deposits from muffler components. ENGLISH 1. F Note: When cleaning carbon deposit, be careful not to damage the catalytic element inside muffler. 6. Replace screen if it is cracked, plugged, or has holes burned through. 7.
MAINTENANCE SRM-2620U 4. Inspect heat shield, and replace if damaged. 5. Install heat shield and muffler. 6. Tighten muffler mounting bolts (or nuts) to 90-110 kgf•cm (80-95 in•lbf). 7. Install muffler cover and attach spark plug lead. 8. Start engine, and warm to operating temperature. 9. Stop engine, and re-tighten mounting bolts (or nuts) to specifications. Carburetor Adjustment Level 2.
SRM-2620U 1. MAINTENANCE A ENGLISH 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; counterclockwise to decrease idle speed. When carburetor adjustment is completed, the cutting attachment should not move at idle, otherwise serious personal injury may result. Lubrication Level 1. Parts Required: Lithium Based Grease.
MAINTENANCE SRM-2620U Nylon Line Head Disassembly Instructions Note: For normal use, Speed Feed® head disassembly is not necessary. However, if circumstances require disassembly, follow these instructions. 1. 2. Press top of locking tabs (A) on both sides of Speed Feed® head to release cover (B) from eyelet carrier (C). A B Remove cover from eyelet carrier. C Nylon Line Replacement Wear Gloves or personal injury may result: ◆ Cutoff knife is sharp. ◆ Gearcase and surrounding area may be hot. 1.
SRM-2620U Insert one end of trimmer line into an eyelet, and push line equal distance through trimmer head. 4. Hold trimmer head while turning knob clockwise to wind line onto spool until about 13 cm (5 in.) of each line remains exposed. ENGLISH 3. MAINTENANCE Trimmer head is now fully loaded and ready for operation. When the wear indicators located at the bottom of the Speed-Feed® head are worn smooth, or if holes appear, replacement of the cover or the entire Speed-Feed® head is required.
MAINTENANCE SRM-2620U 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. Before sharpening, CLOSELY inspect blade for cracks (look at the bottom of each tooth and the center mounting hole closely), missing teeth and bending. If ANY of these problems are discovered, replace the blade.
