OPERATOR SAFETY

Raynaud's Syndrome

A condition known as Raynaud’s Syndrome can occur from exposure to cold and/or vibration. This condition affects the hands and arms, causing tingling, burning, numbness, and loss of color in the fingers. The amount of exposure needed to trigger this is unknown, and varies by individual.

To protect yourself from this condition, take the following precautions:

• Keep your body warm - pay particular attention to head and neck, hands and wrists, and feet and ankles.

• Avoid awkward grips on the unit that may cause stress. Maintain control, but do not hold the unit with an excessively tight grip.

• Take regular rest breaks.

• Exercise and stretch to strengthen muscles, and to

maintain circulation. Keep exposure to vibration at a minimum.

• If you experience discomfort, redness, and/or swelling of the fingers, followed by whitening or loss of feeling, stop using the unit, and contact a doctor.

Repetitive Stress Injuries (RSI)

Overuse of the muscles and tendons of the fingers hands, arms, and shoulders may cause soreness, swelling, numbness, weakness, and pain in these areas. Repetitive hand/wrist movement can put you at high risk for developing a Repetitive Stress Injury (RSI), such as Carpel Tunnel Syndrome (CTS). Carpal Tunnel Syndrome occurs when swelling in the wrist puts pressure on a nerve, resulting in severe pain.

To protect yourself from these conditions, take the following precautions:

• Avoid using your wrist in a bent or twisted position. Try to maintain a straight wrist position.

• Avoid using your thumb and index finger to grip things - use your whole hand.

• Take regular rest breaks.

• Exercise and stretch to strengthen muscles and

maintain circulation.

• Keep exposure to vibration at a minimum.

• Reduce the speed and force of repetitive move-

ments.

• If you experience tingling, numbness, or pain in the fingers, hands, wrists, or arms, stop using the unit immediately, and contact a doctor. Early diagnosis of RSI can help prevent permanent nerve and muscle damage.

ASSEMBLY

WARNING

FUELING

DANGER

Explosion/Fire/Burn Hazard. Gasoline is extremely flammable. Vapors are explosive. Keep at least 50 feet (15 m) away from heat, sparks, open flame, smoking materials, static electricity, and all other sources of ignition when fueling unit.

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.

Follow these important safety precautions to minimize risk of explosion or fire:

• ALWAYS use an approved, "no-spill" type fuel container with tight-fitting caps.

• ALWAYS follow posted safety instructions for filling fuel containers at filling stations.

• ALWAYS place container to be filled with gasoline on the ground to prevent static build-up during filling.

• ALWAYS keep the metal filling pump nozzle in contact with the fuel container while dispensing fuel to prevent buildup and discharge of static electricity.

• NEVER fill fuel container on SUV/truck bed or in trunk of car.

• NEVER smoke near fuel.

• NEVER allow flames or sparks near fuel.

• ALWAYS loosen fuel caps slowly to allow pressure

in tanks and containers to escape

• ALWAYS use extreme care when mixing, storing, or handling fuel.

Fill Fuel Outdoors

• NEVER remove tank cap or refuel a unit while the engine is hot or running

Open Fuel Cap Slowly

• NEVER fill fuel tanks indoors - ALWAYS fill fuel

tanks outdoors over open ground.

• DO NOT overfill fuel tank - ALWAYS allow room in

tank for expansion. Fill tank no more than 95 percent full, or to “Safe Fill Line” if marked on container.

• ALWAYS wipe up spills immediately, and dispose

of fuel soaked wipes safely. Use a fireproof container designed for safe disposal.

• IMMEDIATELY change clothes if fuel spills on

clothing. Wet clothes down with water first to minimize fire risk.

• ALWAYS tighten fuel tank cap securely - check cap

for tightness.

• ALWAYS close fuel container immediately after

refueling.

FUELING

Tighten cap securely

• ALWAYS check fuel system for leaks before using

unit - NEVER start or operate a unit with leaks.

• ALWAYS move at least 3 m (10 ft.) away from

refueling location before starting engine.

The cutting head/work attachment (nylon line head, blade, or PAS/SB attachment) must not move at idle, otherwise serious personal injury may result. Periodic carburetor adjustment may be necessary to assure the cutting head/PAS attachment does not move at idle. If the cutting head/work attachment moves at idle, readjust carburetor according to “Carburetor Adjustment” instructions and idle speed specifications provided in your Operator’s Manual. See your Echo dealer or contact Echo Consumer Support at 1-800-432-ECHO. for help if you have any questions.

Follow these important safety rules when starting your unit:

• DO NOT use unit if cutting head/work attachment moves while engine is idling (throttle trigger not depressed). Adjust idle speed as instructed in your unit’s Operator’s Manual before using unit.

• NEVER start or run your unit indoors or anywhere else where there is poor air circulation. Indoor operation produces dangerous levels of Carbon Monoxide, a colorless and odorless poisonous gas. Carbon Monoxide (CO) causes nausea and other flu-like symptoms if breathed. Prolonged exposure to CO may cause loss of consciousness, brain damage, or death.

• NEVER start a unit near a gasoline container or spilled gasoline.

• ALWAYS move at least 3 m (10 ft.) away from refueling location before starting engine.

• If a protective blade cover is used, ALWAYS re- move blade cover before starting unit. Keep blade cover nearby, and place cover back on blade when unit is off and blade has stopped.

• NEVER start a PAS/HCA (extended shaft, articulat- ing blade) unit while blade is in folded/locked position. Make cutting angle adjustment first.

Do not operate indoors

3 m

(10 ft.)

Do not start within 3 m (10 ft.) of

fueling location

• ALWAYS start the unit with power head on the

ground, with cutting head/work attachment off the ground and clear of debris and all obstructions.

• NEVER “drop start” the unit or attempt to start the

unit while it is resting on blade tips.

• ALWAYS grip the unit firmly when starting to prevent

loss of control when pulling starter handle.

STOPPING

• ALWAYS hold the unit securely on the right side of

your body with both hands. Use left hand on the front handle and right hand on the rear handle, or use left and right handgrips on units equipped with UHandle for metal blade use.

• MAINTAIN a secure, two-handed grip at all times

while unit is in use.

• ALWAYS shut unit off immediately if it shakes or

vibrates excessively when started. Tag unit, and have it checked by an authorized service center before placing back in use.

STOPPING

The “STOP” switch stops the unit by grounding the ignition and preventing the spark plug from discharging a spark. If the STOP switch malfunctions and does not stop the unit when required, use the choke to stall the engine to a stop, and have your Echo dealer repair the switch before using the unit again.

Never drop start unit

Never use one-handed

Use this “Emergency" Stopping sequence only if the STOP switch malfunctions:

• Release trigger and allow engine to return to idle,

and wait for cutting head/work attachment to stop.

• After the engine has returned to idle and cutting

attachment has stopped, place the unit on a safe, flat surface, clear of obstructions.

• Keep one hand on the throttle control handle assem-

bly to maintain control of the unit, and move the choke control lever to the closed, “COLD START”

( ) position to stall the engine.

CHOKE CLOSED

(COLD START POSITION)

OPERATION

• Hold the unit with a secure, two-handed grip, and wait for the engine to stall to a complete stop.

• After the engine stops, disconnect the spark plug lead, and tag the unit to identify it as having a broken STOP switch.

• Do not restart the unit. Have the unit repaired before using it again.

OPERATION

• NEVER operate trimmer with cutting head above knee height - operation with the cutting head well above ground level produces a higher debris flow, and can cause debris to strike you in the face.

• ALWAYS follow instructions provided in Operator’s Manual or with line head for loading or advancing nylon line.

• ALWAYS wear gloves when handling or reloading a line head that has been in use - the gear case and driveshaft get very hot and can cause burns if touched.

Applications

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

Trimming - Feed the spinning line into the material to be cut. Tilt the line head to one side to direct cutting debris away from you:

GT Trimming

Rotation

• Model GT (Curved shaft, clockwise line head rotation)

- Tilt the cutting head down on the left side (air filter side) while cutting to direct cutting debris away from operator. Feed the line gradually into the material you wish to cut, avoiding contact with fences or other barriers.

• Model SRM/PAS/SB (Straight shaft, counter-clock- wise line head rotation) - Tilt the cutting head down on the right side (muffler side) while cutting to direct cutting debris away from operator. Feed the line gradually into the material you wish to cut, avoiding contact with fences or other barriers.

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.

SRM/PAS Brushcutter Operation - Using Metal Grass/Weed, Brush, & Clearing Blades

DANGER

Sharp Blades/Powerful Cutting Action

Contact with moving blades can cause serious or fatal injury. Keep hands, feet, and all other body parts away from blades. Wear all required personal protective equipment. Misuse, improper assembly or care of equipment, or failure to follow all safety and operating instructions, can result in serious injuries to operator and bystanders.

• Read blade selection, assembly, and sharpening

instructions in operator’s manual before using trimmer/brushcutter with metal blade.

• Read, understand, and obey all warnings and in-

structions in this safety manual before using trimmer/ brushcutter with metal blade.

• Read, understand, and obey warnings and instruc-

tions on blade and blade packaging.

• Wear sturdy work gloves when handling, installing,

or removing metal blades.

• Keep blades in protective packaging until ready to

install. Store blades safely after removal to prevent injury from accidental contact.

• Use Blade Protectors to prevent injury and protect

blade teeth during unit transport.

OPERATION

Observe 50’ (15 m) Danger Zone

Spinning blades can throw cutting and ground debris with sufficient force to cause serious injury. Keep bystanders and pets out of the “Safety Zone,” a 50 foot (15 meter) radius around the unit being operated.

• Be alert for bystanders, children, and pets entering

Danger Zone during cutting. Stop unit and clear work area completely before resuming cutting.

• Moving about while cutting changes Danger Zone

boundaries. Make sure all Danger Zone restrictions are followed at all times.

OPERATION

• Make sure the warning sign on the back of the shoulder harness is properly positioned for easy viewing by others.

• Wearing hearing protection and engine noise may prevent you from hearing others about to enter the Safety Zone. Perform regular visual safety checks of the area while cutting to help ensure a safe work area.

Hidden Hazards

Blade contact with exposed or hidden hazards (rocks, metal posts, metal stakes, sprinkler heads, etc.) can result in sudden loss of control, and injury from blade contact or flying debris. Blade damage can result in breakage, and serious injury caused by flying blade fragments. Cutting with a dull or damaged blade increases risk of kick out and loss of control.

Standard Harness

• ALWAYS check area for hidden hazards before starting. Remove hazard, or mark location of hazard to prevent striking it while using brushcutter.

• ALWAYS use extreme care when cutting near ground hazards and other obstacles.

• ALWAYS stop unit immediately and check for blade damage if an object is struck. Do not use blade if cracked, bent, chipped, or dulled by impact. Replace blade before resuming cutting.

• STOP engine immediately if sudden vibration occurs, and check blade for damage before using.

Unit Configuration - Blade Use

Blade use requires specific unit configuration. Blade must be matched to application requirements. See Blade Configuration Chart (Page 15).

• NEVER use a metal blade with a plastic debris shield.

• NEVER use a metal blade on a Model GT (Curved Shaft) Grass Trimmer

• NEVER use an edging blade, circular saw blade, or any other type of saw blade on an SRM/PAS/SB unit. Only use brushcutter blades approved for use by Echo on your model brushcutter.

• NEVER use a dull or damaged blade.

Heavy-Duty Harness

• ALWAYS use blade only for application for which it

was intended

• ALWAYS use the correct front handle for the type of

blade being used. Echo recommends using a UHandle for all blade use.

REACTION FORCES - Push/Pull - Kickback/ Kickout

During normal use, operating a brushcutter with a circular metal blade can produce sudden strong reaction forces that are difficult to control. Strong reaction forces can cause a loss of balance or loss of control of the unit, resulting in serious injury to operator and bystanders.

Understanding what causes these reactive forces may help you to avoid them, and can help you to maintain control of the unit if you experience a sudden reaction during cutting. Reactive forces occur when the force being applied by the cutting teeth of a blade meet resistance, and some of the cutting force is directed back toward the unit. The greater the cutting force or the amount of resistance, the greater the reactive force.

OPERATION

PULL

Contact

Point

Push and Pull Forces

Push and pull forces are reactive forces that push the unit directly toward the operator, or that pull the unit directly away from the operator. These forces are the result of cutting on the sides of the blade. The direction of the force depends on the side of the blade being used, and the direction of blade rotation at the point of contact. The reactive force is in the opposite direction of blade rotation at the contact point, regardless of where the contact is being made. These types of reactive forces are also called “Blade Thrust.”

As shown in the illustration, a blade turning counterclockwise will cause the unit to pull away from the operator if the point of cutting resistance is on the left side of the blade. If the point of cutting resistance is on the right side of the blade, the unit will push back toward the operator. In both examples, the reactive force is in the opposite direction of blade rotation at the contact point where resistance occurs.

Contact

Point

PUSH

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. In most cases, Push, Pull, and Kickout can be reduced or eliminated by:

• Using the correct blade for the cutting job

• Using properly sharpened blades

• Applying consistent, even force to the blade during

the cut

• Avoiding obstacles and ground hazards

• Using extra care when cutting harder materials such

as extremely dry brush, saplings, and small trees

• Cutting from a stable, secure position

Blade Assembly

Follow the instructions in the Operator’s Manual to install a blade on your unit.

Kickout

Blade Assembly

Blade Rotation

• ALWAYS wear gloves when handling and assem- bling blade to unit.

• ALWAYS use correct assembly hardware when installing blade and debris shield.

• ALWAYS use correct blade arbor size.

• ALWAYS install blade with teeth pointed in direction

of rotation.

• ALWAYS tighten blade hardware securely using properly sized tools

• ALWAYS use a new cotter pin when installing or replacing blades.

• ALWAYS check to make sure head locking tool and hex wrench have been removed from cutting head after assembly.

Blade Cutting Capacities

Do not exceed recommended blade cutting capacity. Use a chain saw for larger trees. Exceeding cutting capacity can cause blade binding in cut, blade damage, and risk of injury from blade breakage during cutting. Cutting capacity depends on blade diameter - see operator’s manual or Echo catalog for more information.

Blade Cutting Problems

Binding - Blades may bind in the cut if dull or forced. Binding can damage blade, and result in blade breakage or injury from fragments and flying debris. If a blade binds in a cut, don’t try to get it out by applying “up and down” force to pry the cut open. Applying prying force to the blade can bend the blade, and result in blade failure and injury.

OPERATION

Grass/Weed

Blade

Brush Blade

Clearing Blade

To free a blade that is bound in the cut, stop the engine, and support the trimmer/brushcutter to keep stress off the blade. Push the tree away from the entry point of the cut to open the cut, and pull the blade directly away from the cut in a straight-line motion. Use caution when releasing the tree to avoid being struck by spring-back or falling.

Inspect the blade for damage before proceeding. Sharpen teeth if dull, or replace blade if cracked, bent, missing teeth, or otherwise damaged. (See "Blade Sharpening," on next page for important sharpening information

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

Turn

engine off!

Jammed

Open cut to free blade with

engine off

Inspect jammed blade for

damage

OPERATION

Blade Sharpening

All blades must be kept sharp for best cutting performance. 8 Tooth Grass/Weed blades can be sharpened using the instructions in the Operator’s Manual. Brush and Clearing blades require professional sharpening. Improper sharpening can cause blade failure and result in severe injury.

PLASTIC/METAL TRI-CUT BLADES

Use blade set-up guide for configuring trimmerbrushcutter to use plastic or metal tri-cut blades.

• Use Plastic tri-cut blades to cut grass and weeds

• Use Metal Tri-cut blades to cut reeds, large weeds,

and light brush

• Read, understand, and obey all trimmer-brushcutter safety rules before using tri-cut blades.

• NEVER use tri-cut blades to cut heavy brush, sap- lings, or small trees.

DANGER

Striking concrete or other hard materials with spinning edger blade can cause severe blade damage or breakage, and serious or fatal injuries from flying fragments. Stop unit immediately and check blade if an object is struck. Replace blade if broken, cracked, bent, chipped or otherwise damaged, or if unit began shaking or vibrating after striking the object.

Small stones and other hard debris can be thrown from blade guard, and strike bystanders and nearby buildings. Keep bystanders a minimum of 50 feet (15 m) away when operating edger. Always keep flow of edging debris directed away from windows, parked vehicles, buildings, and bystanders. Always operate edger with unit to right side of body only. Wear eye protection, work gloves, and protective clothing. Use full face shield when edging in rocky or debris-filled soil.

WARNING

Edger operation may scatter ground debris that can cause unstable or slippery footing, and increase the risk of slips and falls. Always maintain proper footing and balance while operating edger. Stop unit if necessary, and remove excessive debris from work path before continuing.

• ALWAYS maintain control using a secure, wrap-

around, two-handed grip when operating the power edger. If the edger strikes a buried object, it may kick up and out of the edging cut forcefully, causing serious injury.

• NEVER operate with unit on left side of operator.

Use only on right side of body to keep operator out of edger debris flow.

• ALWAYS maintain a stable, balanced stance, and

use extra care when walking on uneven, slippery, or sloping surfaces.

• ALWAYS use extreme care when walking on wet

surfaces. Wet surfaces reduce traction, and increase the risk of slips and falls.

• ALWAYS be aware of ground and walkway condi-

tions in the work area, and be prepared to maintain balance and footing when conditions change.

• ALWAYS check edging area for all potential haz-

ards before edging, and remove objects that can be thrown or cause kick-out.

• NEVER edge where the cut line passes directly

over buried hazards such as sprinkler pipes, electric wiring, gas lines, or other similar hazards.

• NEVER operate edger in any area where electric

extension cords are on the ground.

• NEVER use edger in gravel, rocky soil, or in areas

with hard ground cover such as decorative rocks.

• NEVER attempt to clear debris build-up from debris

shield by tapping shield against the ground. ALWAYS shut engine off, wait for blade to stop, and disconnect spark plug wire. Remove debris with a small non-scratching scraper. Wear gloves to protect hands from contact with sharp edges and hot surfaces.

cutter.

Position Edger on right side of

operator only

OPERATION

• NEVER operate edger attachment unless all edger blade hardware has been properly installed.

• ALWAYS use a new split pin each time blade is installed or replaced.

• NEVER operate edger with damaged or missing debris shield.

• NEVER adjust edger blade height with engine running. Stop engine, disconnect spark plug lead, and make adjustments. Wear work gloves to protect hands from hot surfaces if unit has been in operation.

• NEVER allow edger blade to strike concrete or other hard surfaces. Blade contact with concrete and hard surfaces will dislodge pieces of material and cause injury from flying debris.

PAS TILLER/CULTIVATOR ATTACHMENT

Misuse, improper assembly, or use of unapproved attachments, can result in serious injury, engine failure, and voiding of warranty. Use only Echo attachments approved for use on Pro Attachment Series models. Contact with moving cutting or work attachments can cause entanglement and serious injury. Keep clear of moving work attachment.

• NEVER use cultivator if parts are missing or dam- aged.

• NEVER use cultivator if shield is not securely in place.

• NEVER clean or reposition cultivator tines with engine running. Stop engine and remove spark plug lead.

• ALWAYS check ground for hidden obstacles before use, and remove or mark location to prevent striking with tines.

• NEVER use cultivator where there may be buried electrical wire, sprinkler tubing, or underground pipes.

Clearing Jams

DANGER

If the cutting head/work attachment gets jammed by an obstruction and can’t move, the clutch allows the engine to keep running. As soon as the obstruction is removed, the cutting head/work attachment will start moving again. To protect yourself from serious injury when clearing jams, follow these important safety rules:

• ALWAYS switch the unit off and disconnect the

spark plug before clearing a jam.

• NEVER reach for or try to remove jammed material

while the engine is running.

• ALWAYS inspect the cutting head/work attachment

after clearing a jam to make sure all jammed material has been cleared.

• ALWAYS make sure cutting head/work attachment

has not been damaged.

MAINTENANCE

Operating a poorly maintained unit can result in serious injuries to operator and others. Maintain unit as instructed in Operator’s Manual. Keep blades sharp and properly adjusted, and replace broken parts immediately.

Your unit requires regular maintenance for safe operation and reliable performance. Using a poorly-maintained unit can result in an injury caused by a part failure or other malfunction. Follow these important safety instructions to reduce the risk of injury caused by poor maintenance.

• NEVER test for ignition spark by grounding spark plug near cylinder plug hole. A spark

WARNING

could ignite fuel vapor, causing serious injury from explosion or fire.

MAINTENANCE

• NEVER use a unit with broken, damaged, missing, or worn parts. Contact your dealer for repairs if problems are found.

• NEVER use substitute parts, parts from other models or brands, or used parts, when performing maintenance or repairs. Use only new parts that are manufactured for your specific serial number and model trimmer.

• NEVER make temporary repairs on a unit - taking shortcuts or using questionable parts and performing repairs that are not approved by Echo may create a safety hazard that can cause serious injury. Improper repair may also cause premature part failures, and void your product warranty.

• ALWAYS keep blades sharp. Cutting with dull blades increases the chances of jams and binding, reduces cutting efficiency, and increases operator fatigue.

• ALWAYS keep hedge clipper blades properly adjusted. Improperly adjusted blades may result in poor cutting performance, increased risk of jams, and premature blade wear or failure.

• ALWAYS keep blades and gear case properly lubricated. Poor lubrication can cause result in part failures and cause overheating.

• ALWAYS keep fasteners tightened securely, and use the correct tools for the job. Operation with loose fasteners can result in hazardous operation.

• ALWAYS do a safety check after performing any service or maintenance on the unit. Make sure all parts have been properly installed, all hardware is properly tightened, and all guards and shields are in place.

• NEVER reach into any opening while the engine is running. Moving parts may not be visible through openings.

• ALWAYS stop unit immediately and correct any

problem if unit does not run properly after performing service or maintenance. Operating a unit that has been improperly repaired may result in serious injury.

• ALWAYS have major service performed by a

qualified service technician. See your dealer for authorized service support.

STORAGE

Improper storage can result in fire and damage to equipment and property. Follow storage instructions in Operator’s Manual. Obey all rules for safe fuel handling.

Your Operator’s Manual contains detailed instructions for preparing your unit for storage. Follow the instructions in your manual carefully, and make sure you observe these important safety precautions:

• NEVER store a unit with fuel mix in the fuel tank.
