OPERATION SRM-3020 Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit so that exhaust is directed away from your face and body. 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.
SRM-3020 OPERATION *ANSI standards require brush cutters be equipped with a barrier bar or restrictive harness. U-Handle ensures a higher safety factor. Do Not install blades on GT (Curved Shaft) model trimmers. • Arbor diameter of upper blade plate must match arbor diameter of blades. • A new cotter pin is required each time a blade is installed. • Brush cutters over 7.5 kg (16.5 lbs.) dry weight (without fuel) require a double shoulder harness.
OPERATION SRM-3020 3-Tooth Grass/Weed Blades may be used where ever 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.
SRM-3020 OPERATION Use blade protectors to protect blade teeth during unit transportation. ENGLISH 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.
OPERATION SRM-3020 Fuel Requirements Gasoline - Use 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. ECHO Red Armor™ Fuel (Power Fuel™) is 93 octane, ethanol-free fuel premixed with ECHO Red Armor™ engine oil at 50:1 ratio.
SRM-3020 ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ ◆ 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.
OPERATION SRM-3020 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. • Empty the fuel tank prior to storing the unit. 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.

OPERATION SRM-3020 Scything Scything - Swing the cutting head in a level arc, gradually feeding the line into the material being cut. Move forward with each arc to cut a swath. Width of cutting swath depends on arc. Use a larger arc for a wider swath, or a smaller arc for a narrow swath. Keep line head tilted to direct cutting debris forward or away from you. Operating Techniques • Debris flows in direction of lne head rotation.
SRM-3020 OPERATION Kickout Kickout is also a reactive force caused by resistance to cutting, but the direction of blade thrust is lateral (to the left or right of the blade), instead of forward or back toward the operator.
MAINTENANCE SRM-3020 Inspect the blade for damage before proceeding. Sharpen teeth if dull, or replace blade if cracked, bent, missing teeth, or otherwise damaged. To prevent binding: • Keep blades sharp • Avoid excessive pressure during cuts • Don’t exceed cutting capacity of blade • Don’t use blades with damaged or missing cutting teeth • Don’t rock blades in cut MAINTENANCE Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all openings.
