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.
The components of this machine generate an electromagnetic
field during operation, which may interfere with some
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. In the absence of such information, ECHO does not
recommend the use of this machine by anyone who has a
pacemaker.
Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in
injury. Read and follow all safety and operation instructions to
minimize risk of injury. Failure to follow instructions may result
in painful wrist/hand/arm injuries.
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.

SAFETY HC-2210/2810

Repetitive Stress Injuries (RSI)
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 exercises 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.
All over head electrical conductors and communications wires
can have electricity flow with high voltages. This unit is not
insulated against electrical current. Never touch wires directly
or indirectly, otherwise serious injury or death may result.

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.
Metal cutters can also create sparks if the cutter strikes rocks,
metal, or other hard objects. Contact local fire authorities for
laws or regulations regarding fire prevention requirements.

HC-2210/2810 OPERATION
X7702248100 17

Fuel
Diesel fuels and 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 diesel or 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. Diesel or alternative
fuels may also cause premature deterioration of fuel lines,
gaskets, carburetors and other engine components.
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. Use of ECHO branded fuel is
recommended to extend engine life in all air-cooled 2-stroke and 2/4-stroke
hybrid engines.
Two Stroke Oil - A two-stroke engine oil, such as ECHO branded 2-stroke
oils, meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FD Standards must
be used. ECHO branded 2-stroke oils meet these standards. Engine
problems due to inadequate lubrication caused by failure to use an ISO-L-
EGD (ISO/CD 13738) and J.A.S.O. M345-FD certified oil will void the two-
stroke engine warranty.
2-Stroke engine oil contains petroleum distillates and other
additives that may be harmful if swallowed. Heated oil can
release vapors that can cause flash fire, or ignite with explosive
force. Read and follow the oil manufacturer’s instructions, and
observe all safety warnings and precautions for handling
flammable liquids. For more detailed safety and first aid
information, visit www.echo-usa.com for a copy of the Material
Safety Data Sheet.
◆ KEEP OUT OF REACH OF CHILDREN.
◆ If swallowed, do not induce vomiting. CALL PHYSICIAN OR
A POISON CONTROL CENTER IMMEDIATELY.
◆ WEAR SAFETY GLASSES when mixing or handling.

OPERATION HC-2210/2810
18 X7702248100
© 09/19 ECHO Incorporated
◆ AVOID repeated or prolonged skin contact.
◆ AVOID inhaling oil mists or vapors.
ECHO branded 2-stroke oils may be mixed at 50:1 ratio for
application in all ECHO engines sold in the past regardless of ratio
specified in those manuals.
Handling Fuel
Fuel is VERY flammable. Use extreme care when mixing, storing
or handling, or serious personal injury may result.
◆ 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.
◆ Securely tighten fuel tank cap and close fuel container
after refueling.
◆ Inspect for fuel leakage. If fuel leakage is found, do not
start or operate unit until leakage is repaired.
◆ Move at least 3 m (10 ft.) from refueling location before
starting the engine.
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.

HC-2210/2810 OPERATION
X7702248100 19
© 09/19 ECHO Incorporated
Mixing Instructions
1. Fill an approved fuel container
with half of the required
amount of gasoline.
2. Add the proper amount of
2-stroke oil to gasoline.
3. Close container and shake to
mix oil with gasoline.
4. Add remaining gasoline, close
fuel container, and remix.
Spilled fuel is a leading cause of hydrocarbon emissions. Some
locatins may require the use of automatic fuel shut-off containers to
reduce fuel spillage.
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. Store in a well-ventilated, unoccupied building, away from
sparks and flames.
• Empty the fuel tank prior to storing the unit. Return unused fuel to an
approved fuel storage container.
Stored fuel ages. Do not mix more fuel than you expect to use in 30
days, 90 days when a fuel stabilizer is added.
Stored two-stroke fuel may separate. ALWAYS shake fuel container
thoroughly before each use.
Used oil and gasoline, and soiled towels are hazardous waste
materials. Disposal laws vary by locality.

or handling, or serious personal injury may result.
1. Use a clean rag to remove loose
dirt from around fuel cap and
empty fuel tank.
2. Carefully pull the fuel line and filter
from the tank and install a new
filter.
Note: Federal EPA regulations
require all model year 2012
and later gasoline powered
engines produced for sale in
the United States to be equipped with a special low
permeation fuel supply hose between the carburetor and fuel
tank. When servicing model year 2012 and later equipment,
only fuel supply hoses certified by EPA can be used to
replace the original equipment supply hose. Fines up to
$37,500 may be enforced for using an un-certified
replacement part.

Spark Plug
Level 2.
Use only NGK BPMR-8Y otherwise severe engine damage may
occur.
1. Remove spark plug and check
for fouling, worn and rounded
center electrode.
2. Clean the plug or replace with
a new one. DO NOT sand blast
to clean. Remaining sand will
damage engine.
3. Adjust spark plug gap by
bending outer electrode.
4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).
Cooling System
Level 2.
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.
Parts Required: Spark Plug
0.65 mm (0.026 in.)

necessary to assure blades do not move at idle.
If blades move, readjust carburetor according to these
instructions, or see your ECHO Dealer.
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-in
period your engine performance will increase and exhaust emissions will
stabilize. Idle speed can be adjusted as required.

High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,100 feet above sea level (ASL)
(96.0 kPa). To maintain proper engine operation above 1,100 feet ASL the
carburetor may
need to be adjusted by an authorized ECHO service dealer.
If the engine is adjusted for operation above 1,100 feet ASL, the
carburetor must be re-adjusted when operating the engine below
1,100 feet ASL, otherwise severe engine damage may result.
