OPERATION SRM-3020T
• For barrier bar or U-handle, follow instructions supplied with either blade conversion kit or U-handle kit, and verify blade is secured properly.
• A new cotter pin is required each time a blade is installed.
• Shoulder harnesses may be used on all trimmers and brushcutters to reduce operator fatigue. Brushcutters over 7.5 kg (16.5 lbs.) dry weight
(without fuel) and U-handle brushcutters require a double shoulder harness.
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
Not all blades are compatible with all trimmers. Visit www.echousa.com or www.shindaiwa-usa.com to find compatible blades
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. Never use an edging blade, circular saw blade, or any other type of unapproved blade.
3-Tooth Grass/Weed Blades may be used wherever the nylon line head is used. DO NOT use this blade for heavy weeds or brush.
8-Tooth Weed/Grass Blade is designed for grass, garden debris and thick weeds up to 19 mm (0.75 in.) diameter. DO NOT use this blade for brush or heavy woody growth.
80-Tooth Brush Blade is designed for cutting brush and woody growth up to 13 mm (0.5 in.) diameter.
22-Tooth Clearing Blade is designed for dense thickets and saplings up to
64 mm (2.5 in.) diameter.
A trimmer/brushcutter with a metal blade can cause serious injuries if handled improperly.

SRM-3020T OPERATION
Always use extreme care when carrying or handling the equipment to avoid contact with the cutting edges of the blade. Use the optional blade cover when unit is not in use.
Keep blades in protective packaging until ready to install. Store blades safely after removal to prevent injury from accidental contact.
Use blade protectors to protect blade teeth during unit transportation.
Use Shoulder/Waist Harness
Use of the shoulder/waist harness is recommended for all trimmer/ brushcutter 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. Safety to the operator is also enhanced by reducing the possibility of blade contact with the operator's hands and feet by restricting trimmer movement.
Make sure the warning sign on the back of the shoulder harness can be read easily.
Note: In case of emergency, disconnect the trimmer from the harness.

OPERATION
Fuel
SRM-3020T
Diesel fuels and 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 diesel or alternative fuels can cause performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper clutch engagement. Diesel or alternative fuels can also cause premature deterioration of fuel lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use fresh (purchased within the last 30 days from the pump) 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.
Two Stroke Oil - A two-stroke engine oil, such as ECHO branded 2-stroke oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must be used. ECHO branded 2-stroke oils meet these standards. Engine problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the twostroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other additives that may be harmful if swallowed. Heated oil can release vapors that can cause flash fire, or ignite with explosive force. Read and follow the oil manufacturer’s instructions, and observe all safety warnings and precautions for handling flammable liquids. For more detailed safety and first aid information, visit www.echo-usa.com for a copy of the Material
Safety Data Sheet.

KEEP OUT OF REACH OF CHILDREN.
If swallowed, do not induce vomiting. CALL PHYSICIAN OR
A POISON CONTROL CENTER IMMEDIATELY.
WEAR SAFETY GLASSES when mixing or handling.

AVOID repeated or prolonged skin contact.
AVOID inhaling oil mists or vapors.
OPERATION
ECHO branded 2-stroke oils 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 will result.
◆
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.
Securely tighten fuel tank cap and close fuel container after refueling.
Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
Move at least 3 m (10 ft.) from refueling location before starting the engine.
Gasoline vapor is heavier than air, and can travel along the ground to nearby sources of ignition such as electrical motors, pilot lights, and hot or running engines. Vapors ignited by an ignition source can flash back to the fuel container, resulting in an explosion, fire, serious or fatal injuries, and extensive property damage.

Spilled fuel is a leading cause of hydrocarbon emissions. Some locations may require the use of automatic fuel shut-off containers to reduce fuel spillage.
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 two-stroke fuel can separate. ALWAYS shake fuel container thoroughly before each use.
Used oil and gasoline, and soiled towels are hazardous waste materials. Disposal laws vary by locality.
