Make sure the mask does not impair your vision, and replace the mask as needed to prevent air restrictions.

Use The Correct Personal Protection

WARNING

Before Each Use Inspect:

• For damaged parts.
• Loose or missing fasteners.
• Cutting attachments for damage (cracked, chipped, etc.).
• Cutting attachment is securely fastened.
• Cutting shield is correct for cutting attachment and secured according to this manual.
• For fuel leaks from any point of the fuel system (tank to carburetor).
• Manufacturer recommended flexible non-metallic line is installed in the trimmer head.

Proper Operating Position

WARNING

• The use of the optional shoulder / waist harness for ALL use of the mower / cutter is recommended, not only for the operation of the blade.
• Keep a firm grip on both handles.
• Be sure front handle is installed according to assembly instructions.
• For barrier bar or u-handle, follow instructions supplied with either blade conversion kit or U-handle kit.

Fuel Handling

****DANGER

• Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury can result.
• ix and pour fuel outdoors where there are no sparks and flames.
• Slowly remove the fuel cap only after stopping the engine.
• Do not smoke while fueling or mixing fuel.
• Wipe spilled fuel from the unit.
• Move at least 3 m (10 ft) away from the fueling source and site before starting engine.

Work Area

• Review the area to be cleared. Remove potential hazards such as rocks, broken glass, nails, wire, or metal objects, which can be thrown.
• Clear the area of children, bystanders and pets.
• At a minimum, keep all children, bystanders and pets outside a 15 m (50 ft) radius.

• Allow engine to cool.
• Store unit in a dry, dust free place, out of the reach of children.

WARNING
Read and understand all provided literature before use. Failure to do so could result in serious injury.

Cutting Technique

• Nylon line heads may be used for trimming, scything, edging, scalping grass and light weeds.

• GT models: Tilt cutting head to the left while cutting to direct debris away from the operator.

• SRM models: Tilt cutting head to the right while cutting to direct debris away from the operator.

• Either model: To “scythe” swing the cutting head in a level arc feeding the line into the material to be cut.

WARNING

• The cutting attachment will continue to rotate even after the throttle is released, maintain control of the unit until it has come to a complete stop.
• Avoid contact with blades. Wear gloves to protect hands when handling or maintaining blades. Metal blades are very sharp and can cause severe injuries, even if engine is off and blades are not moving.
• Blade thrust may occur when the spinning blade contacts an object that it does not immediately cut. Following proper cutting techniques will prevent blade thrust.
• Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any direction, and possibly cause operator to lose control of the unit.
• Blade thrust can occur without warning if the blade snags, stalls or binds.
• Blade thrust is more likely to occur in areas where it is difficult to see the material to be cut.
• Blade must be matched with material to be cut

Recommended product configurations based on material to be cut:

Material to be Cut| Grass (SRM & GT)| Weed/Grass (SRM & GT)| Weed/Grass (SRM)| Brush (˂0.5”) (SRM)| Clearing (˂2.5”) (SRM)
---|---|---|---|---|---
Cutting Attachment| Nylon lancehead included| Maxi-Cut head, Pro Maxi-Cut head| 3 Tooth Blade8 Tooth Blade| 80 Tooth Blade| 22 Tooth Blade
Shield| Shield Included| Included with unit| Included with unit| Included with Blade| Included with Blade
Handle| Handle Included| U-Handle or Support Handle w/ Barrier Bar| U-Handle or Support Handle w/ Barrier Bar| U-Handle or Support Handle w/ Barrier Bar| U-Handle or Support Handle w/ Barrier Bar
Harness| Not Required| Not Required| Supplied w/Kit| Supplied w/Kit| Supplied w/Kit

ANSI standards require brush cutters be equipped with a barrier bar or restrictive harness. U-Handle ensures a higher safety factor

WARNING

• Blades cannot be used on GT models.
• Use only ECHO approved parts. Failure to use the correct parts can cause the blade to fly off. Seriously injury to the operator and / or bystanders can occur.

Before Each Use When Using A Blade

• Verify the handles are installed according to the manufacturers recommendation.
• Verify the blade is secured properly based on instructions with blade conversion kit.
• Discard blades that are bent, warped, cracked, broken, or damaged in any way.
• Use a sharp blade, dull blades are more likely to snag and thrust.

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.
• When sharpening a blade, always remove the same amount of materials from each tooth to maintain balance. A blade that is not balanced will cause unsafe handling due to vibration and can result in blade failure.
• File each tooth at a 30° angle a specific number of times, e.g., four strokes per tooth. Work your way around the blade until all teeth are sharp.
• DO NOT file the ‘gullet’ (radius) of the tooth with the flat file. The radius must remain. A sharp corner will lead to a crack and blade failure.
• 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.
• After sharpening teeth, check each tooth radius for evidence of a square (sharp) corner. Use the round (rat tail) file to renew the radius.

EPA EMISSIONS CONTROL INFORMATION
The emission control system for the engine is EM (engine modification) and, if the second to last character of the Engine Family on the Emission Control Information label (see example) is “B”, “C”, “K”, or “T”, the emission control system is EM and TWC (3-way catalyst). The fuel tank/fuel line emission control system is EVAP (evaporative emissions).

An Emission Control Label is located on the engine. (This is an EXAMPLE ONLY, information on label varies by ENGINE FAMILY).

Product Emission Durability (Emission Compliance Period).
The 50 or 300 hour emission compliance period is the time span selected by the manufacturer certifying the engine emissions output meets applicable emissions regulations, provided that approved maintenance procedures are followed as listed in the Maintenance Section of this manual.
