EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold --
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
recommendedbecausethe minimum exposure which mighttriggerthe
ailmentisunknown.
• 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 trimmer 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.
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).AnextremeRSIconditionisCarpalTunnelSyndrome
(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.
• Takeperiodicbreakstominimizerepeti-
tion and rest your hands.
• Reduce the speed & force in which you
do the repetitive movement.
• Do exercises to strengthen the hand and
armmuscles.
• 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
likelypermanent nerve and muscle
damage can be prevented.
EQUIPMENT
Before operation a complete check of the unit must be performed;
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Inspect shield for damage and ensure that the shield is securely in
place. Replace if shield is damaged or missing.
• Check that the tines are firmly attached and in safe operating condi-
tion.
• Keep exhaust area clear of flammable debris. Avoid contact during
andimmediatelyafteroperation.

WARNING DANGER
Do not operate this unit indoors or in inadequately ventilated
areas.
• Carry unit to tilling/cultivating area using plastic carry handle and
upper handle. Avoid contact with tines or hot engine parts.
• Check the area to be tilled or cultivated. Look for any hazards and
obstructions that could contribute to unsafe conditions.
• Remove all rocks, debris, and other materials that could become
jammedinthetines.
• Do not till or cultivate in areas where there may be hidden hazards,
such as sprinkler heads and pipes, buried power cables or gas lines,
orothersimilarhazards.
• Start the unit as shown in “Starting” instructions.
• Hold unit securely, using both hands to grip hand grips.
• Depress throttle trigger gradually to begin operation.
• Release throttle trigger to stop tines.
• Allow engine to return to idle, and move switch to “Stop” position to
stop engine.
TILLING–Recommendedtillingdepthis6–8 inches
Install Tines with individual tines angled forward, toward front of unit.
(SeeTineRemoval/Cleaning/Installation,page20)
• Use a forward/backward motion to till soil. Allow tines to dig into
soil, then pull unit back to break up and pulverize clumps. Tilling
depth is controlled by the number of times the forward/backward
motion is used in an area.
• Controllingtillingdepth :
• Shallow tilling: Move tiller over soil surface quickly. Tines should be
in cultivating position.
• Deepertilling: Move tiller oversoilslowly. Allowtillertoworkthe
same area until desired depth is reached.
• Big Weeds/Tough Roots: Rock tiller back and forth over tough spot
until the tines slice through the roots or weeds.
• Digging Holes: Hold tiller in place, and allow tines to dig down into
the soil. Allow tines to dig approximately 6 – 8 inches deep, then lift
unit up and out. Remove loose soil with shovel or rake. Resume
digging with rotating tiller tines until desired depth is reached.
CULTIVATING–Recommendedcultivatingdepthis2–3 inches
Install Tines with individual tines angled rearward, toward the operator.
(SeeTineRemoval/Cleaning/Installation,page20)
Allow unit to move forward slowly. Pull unit back to cut vegetation and
cultivate soil to desired depth. Repeat forward/backward motion as
needed.

COOLING SYSTEM CLEANING
Level2.
Tools required: CrossHeadScrewdriver, 3mmHexwrench,Pointed
WoodStick,25-50mm(1-2in.)mediumbristle
paint brush.
Parts Required: None.
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. Disconnect spark plug lead. Remove spark plug and throttle cable
end from the carburetor swivel.
2. Remove four screws from starter cover, lift the cover from the
engine and lay to the side.
NOTE
The throttle cable remains assembled to the cover.

IMPORTANT
DO NOT use a metal scraper to remove dirt from the cylinder fins.

NOTE
When installing the cylinder cover, be certain the muffler gasket
tabs are locked into the muffler grill slots and the stop switch lead is
seated in the relief notch.

CARBURETORADJUSTMENT
Level2.
Tools required: Screwdriver,Tachometer(ECHOP/N99051130017).
Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with emission regulations. In addition, the carburetor is
equipped with HI (A) and LO (B) needle adjustment limiters that
prevent settings outside acceptable limits.
1. Before adjusting the carburetor, clean or replace the air filter and
spark arrestor screen.
WARNING DANGER
Sharp rotating tines! Do not allow tines to touch anything during
carburetor adjustment. Contact with revolving tines will cause
severe injury.
2. Start engine and run for several minutes to reach operating
temperature.
3. Stop engine. Turn HI (A) speed needle CCW (counter clockwise)
to stop. Turn LO (B) speed needle midway between full CCW and
CW (clockwise) stops.
4. Idle Speed Adjustment.
-Start engine and turn idle speed adjustment screw (C), CW until
the tines begin to turn, then turn the screw CCW until tines stop
turning. Turn screw CCW an additional 1/4 turn.
5. Accelerate to full throttle for 2-3 seconds to clear excess fuel from
engine then return to idle. Accelerate to full throttle to check for
smooth transition from idle to full throttle. If engine hesitates, turn
LO (B) needle CCW an additional 1/8 turn and repeat acceleration.
Continue adjusting until smooth acceleration results.
6. Check HI (A) speed RPM at W.O.T. (Wide Open Throttle). HI
speed RPM should be set to specifications found on page 9
"Specifications" of this manual.
7. Check idle speed and reset if necessary. If a tachometer is avail-
able, idle speed should be set to the specification found on page 9
