HotHumid Weather
Heavy protective clothing can increase operator fatigue
which may lead to heat stroke. Schedule heavy work for
early moming
or late afternoon hours when temperatures
are cooler.
AWARNING
The ignition components of tbis machine generate an electromagnetic field during operation which may interfere
with sorne pacemakers.
To reduce the risk of serious or fatal injury, persons with pacemakers should consult with
their physician and the pacemaker manufacturer before operating this machine. ln the absence
of such informa-
tion, ECHO does not recommend the use
of ECHO products by anyone who has apacemaker.
Extended Operation/Extreme Conditions
Il is believed that acondition 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 sensa-
tions, followed by loss
of color and numbness in the fingers. The following precautions are strongly recommended,
because the minimum exposure, which might trigger the aiiment, is unknown.
•Keep your body warm, especially the head, neck, feet, ankles, hands,
and wrists.
•Maintain good blood circulation by performing vigorous arm exer-
cises during frequent work breaks, and also by not smoking.
•Limit the hours
of operation. Try to fill each day with jobs where op-
erating the unit or other hand-held power equipment is not required.
Ifyou experience discomfort, redness, and swelling ofthe fingers fol-
lowed by whitening and loss
of feeling, consult your physician before
further exposing yourselfto cold and vibration.

GRASS TRIMMERIBRUSH CUTTER 5
OPERATOR'S MANUAL
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the fingers, bands, arms, and shoulders may cause soreness,
swel1ing, numbness, weakness, and extreme pain in tbose areas. Certain repetitive band activities may put you at ahigb
risk for developing aRepetitive Stress Injury (RS!). An extrerne RSI condition
is Carpal Tunnel Syndrome (CTS), wbicb
could occur when your wrist swells and squeezes avital nerve that runs through the area. Sorne 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 RSIfCTS, do the following:
•Avoid using your wrist in abent, extended, or twisted position.
Instead try
to maintain astraight wrist position. AIso, wben grasping,
use your whole hand, not
just the thumb and index finger.
•Take periodic breaks
to minimize repetition and rest your bands.
•Reduce the speed and force with which you do the repetitive move-
ment.
•Do exercise to strengthen the band and arm muscles.
•lmmediately stop using aIl power equiprnent and consult adoctor
if
you feel tingling numbness, or pain in the fingers, bands, wrists, or
arms. The sooner RSIfCTS
is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.
ADANGER
Do not operate tbis product indoors or in inadequately ventilated
areas. Engine exbaust contains poisonous emissions and can cause
serious injury
or death.
Read the Manua/s
•Provide aIl users of this equipment with the Operator's Manual and
Safety Manual for instructions on Safe Operation.
C/ear the WOTk Area
•Spectators and fellow workers must be warned, and cbildren and
animaIs prevented from coming nearer than
15 m(50 ft.) wbile the
unit
is in use.
Keep aFirm Grip
•Hold the front and rear bandles with both bands, with thumbs and
fingers encircling the bandles.
Keep aSoUd Stance
•Maintain footing and balance at aIl tirnes. Do not stand on slippery,
uneven or unstable surfaces. Do not work in odd positions or on lad-
ders. Do not over reacb.

Brush Blade (PIN 69500120331) is designed for cutting
brush and woody growth up to
13 mm (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 (PIN 99944200200) Use of the Shoul-
der/Waist Harness
is recommended for ALL Trîmmer/Brush Cutter
use, notjust Blade operation. The Shoulder/Waist Harness when used
in atrimming operation with nylon line head suspends the trimmer
from the operator's shoulder and reduces opemtor fatigue.
During blade operation, the same fatigue reduction is achieved. Safety
to the operator is also enhanced by reducing the possibility
ofblade
contact with the operator's hands and feet by restricting trimmer move-
ment.
NOTE
In case of Emergency, pull up on the Quick Re1ease Collar to dis-
connect the trimmer from the harness. t

FUEL
NOTICE: Use ofunmixed, improperly mixe d, or fuel older than 90 days, (stale fuel), may cause hard starting, poor
performance, or severe engine damage and void the product warranty. Read and follow instructions
in the Storage
section
of this manual.
AWARNING
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 alternative fuels may cause performance
problems, loss
of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited
to, improper clutch engagement. Alternative fuels may also cause premature deterioration
offuellines, gaskets,
carburetors and other engine components.
FuelRequirements
Gasoline -Use 89 Octane [R+MJ2] (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 alco-
hol) is
NOT approved.
