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.

Eye Protection

Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.

Hand Protection

Wear no-slip, heavy-duty work gloves to improve your grip on the handle. Gloves also reduce the transmission of
machine vibration to your hands.

Hearing Protection

ECHO recommends wearing hearing protection whenever unit is used.

Proper Clothing

Wear snug fitting, durable clothing;

• Pants should have long legs, shirts with long sleeves.

• DO NOT WEAR SHORTS,

• DO NOT WEAR TIES, SCARFS, JEWELRY.
Wear protective hair covering to contain long hair.
Wear sturdy work shoes with nonskid soles;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

Hot Humid Weather

Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early
morning or late afternoon hours when temperatures are cooler.

Extended Operation/Extreme Conditions

It is believed that a condition called Raynaud’s Phenomenon, which affects the fingers of certain individuals, may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning
sensations, followed by loss of color and numbness in the fingers. The following precautions are strongly recom­mended, because the minimum exposure, which might trigger the ailment, is unknown.

• Keep your body warm, especially the head, neck, feet, ankles, hands,
and wrists.

• Maintain good blood circulation by performing vigorous arm exer­cises during frequent work breaks, and also by not smoking.

• Limit the hours of operation. Try to fill each day with jobs where
operating the unit or other hand-held power equipment is not
required.

• If you experience discomfort, redness, and swelling of the fingers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.

GRASS TRIMMER/BRUSH CUTTER

OPERATOR'S MANUAL

Repetitive Stress Injuries

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. Some believe that prolonged
exposure to vibration may contribute to CTS. CTS can cause severe pain for months or even years.

To reduce the risk of RSI/CTS, do the following:

• Avoid using your wrist in a bent, extended, or twisted position.
Instead try to maintain a straight wrist position. Also, when grasping,
use your whole hand, not just the thumb and index finger.

• Take periodic breaks to minimize repetition and rest your hands.

• Reduce the speed and force with which you do the repetitive move­ment.

• Do exercise to strengthen the hand and arm muscles.

• Immediately stop using all power equipment and consult a doctor if
you feel tingling, numbness, or pain in the fingers, hands, wrists, or
arms. The sooner RSI/CTS is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.

Read the Manuals

• Provide all users of this equipment with the Operator’s Manual and
Safety Manual for instructions on Safe Operation.

Clear the Work Area

• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while the unit
is in use.

Keep a Firm Grip

• Hold the front and rear handles with both hands, with thumbs and
fingers encircling the handles.

Keep a Solid Stance

• Maintain footing and balance at all times. Do not stand on slippery,
uneven or unstable surfaces. Do not work in odd positions or on
ladders. Do not over reach.

Avoid Hot Surfaces

• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.

OPERATION

Preparing the Trimmer/Brush Cutter for Blade Use

WITH BLADES

WARNING DANGER

Blade use DEMANDS specific Brush Cutter configuration. Operation without specified shield, barrier bar or U­handle, and harness can result in serious personal injury. Follow installation instructions included in optional kits.

Grass/Weed Blades Require:

Install Blade Conversion Kit, Includes metal shield (A),
barrier bar (B), and shoulder harness (C).

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.

A

B

C

Brush/Clearing Blades Require:

Install U-Handle / Blade Conversion Kit, Includes
metal shield (A), shoulder harness with hip pad (C),
and U-Handles (D).

Choosing the Correct Blade

A

C

D

W ARNING DANGER

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.

12

Plastic/Nylon 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 (P/N 69600120331) is designed for grass,
garden debris and thick weeds. DO NOT use this blade for brush or
heavy woody growth, 19 mm (3/4 in.) diameter or larger.

80 Tooth Brush Blade (P/N 69500120331) is designed for cutting brush
and woody growth up to 64 mm (2-1/2 in.) diameter.

22 Tooth Clearing Blade (99944200130) is designed for dense thickets
and saplings up to 64 mm (2-1/2 in.) diameter.

Use Shoulder/Waist Harness (P/N 99944200200) Use of the Shoulder/
Waist Harness is recommended for ALL Trimmer/Brush Cutter 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.

FUEL

Fuel Requirements

GRASS TRIMMER/BRUSH CUTTER

OPERATOR'S MANUAL

13

Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline
known to be good quality. Gasoline may contain up to 15% MTBE
(methyl tertiary-butyl ether). Gasohol containing methyl (wood) alcohol
is NOT approved.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD

13738) and J.A.S.O. FC Standards must be used. Echo brand premium
Power Blend TM Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an
ISO-L-EGD and J.A.S.O. FC certified oil, such as Echo premium Power
Blend TM, will void the two-stroke engine warranty. (Emission related
parts only are covered for two years, regardless of two-stroke oil used,
per the statement listed in the Emission Defect Warranty Explanation.)

IMPORTANT

Echo premium Power Blend TM Universal 2-Stroke Oil may be mixed
at 50:1 ratio for application in all Echo engines sold in the past
regardless of ratio specified in those manuals.

COOLING SYSTEM

Level 2.

Tools required: Cross Head Screwdriver, 4 mm Hex Wrench, Cleaning

Brush, 25 - 50 mm (1 - 2 in.)

Parts Required: None if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air
must pass freely through the cylinder fin area. This flow of air
carries combustion heat away from the engine.

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.

GRASS TRIMMER/BRUSH CUTTER

SHARPENING METAL BLADES

Three styles of metal blades are approved for use on the ECHO 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.

Tool required: Flat file (preferred). Electric grinder if special care is

used. Round (rat tail) file for gullet (radius).

1 . File each tooth at a 30 degree angle a specific number of times,

eg. 4 strokes per tooth. Work your way around the blade until
all teeth are sharp.

OPERATOR'S MANUAL

23

2 . 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.

IMPORTANT

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.

3. After sharpening teeth, check each tooth radius for evidence of a
square (sharp) corner. Use the round (rat tail) file to renew the
radius.
