ENGLISH
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 handheld 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
(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.
Do not operate this product indoors or in inadequately
ventilated areas. Engine exhaust contains poisonous emissions
and can cause serious injury or death.
Read the Manuals
ENGLISH
• 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.
Use Proper Clothing & Equipment
• Always wear head protection with full face shield to help protect against
falling branches and debris.
Keep a Firm Grip
• Always hold throttle handle and support handle with thumbs and fingers
tightly 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.
• Operate the Power PrunerTM only from the ground or out of an approved
bucket lift.
• Always evaluate the branches to be pruned for hazards such as loose
dead branches which may fall and strike the operator or helpers. Remove
hazards before pruning.
• Plan retreat path from falling objects.
• Cut branches bounce when striking ground.
• Check that shoulder harness is adjusted for safe, comfortable operation.
• Turn the Power PrunerTM off when moving from tree to tree.
• Avoid any contact with saw chain..
Avoid Hot Surfaces
• Keep exhaust area clear of flammable
debris. Avoid contact during and
immediately after operation.
Kickback
Kickback can lead to dangerous loss of control of the Power
PrunerTM and result in serious injury to the operator or any one
standing close by. Hold the Power PrunerTM firmly with both
hands with thumbs and fingers encircling the front and rear
handles. Be aware of the down and outward path the pruner will
take after the cut is made.
Kickback may occur when the moving saw
chain at the nose or tip of the guide bar
touches an object, or when the wood
closes in and pinches the saw chain in the
cut. In some cases this may cause a
lightning-fast reverse action, kicking the
guide bar and saw chain up and back or
down and back towards the operator.
Either of these reactions may cause the
operator to lose control of the Power
PrunerTM which could result in serious
personal injury.
With a basic understanding of kickback,
you can reduce or eliminate the element of surprise which contributes to
accidents.
Avoid contact of the guide bar tip with any object while the saw chain is
moving.
Cut only wood. Avoid striking concrete, metal, wire, or other obstructions
which could cause kickback or damage to the saw chain.
ENGLISH
If the saw chain does strike a foreign object, immediately stop the engine,
inspect and repair the Power PrunerTM if necessary.

• 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.
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
states may require the use of automatic fuel shut-off containers to
reduce fuel spillage.
• Empty the fuel tank prior to storing the unit. Return
unused fuel to an approved fuel storage container.
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.
ENGLISH
Stored fuel ages. Do not mix more fuel than you expect to use in thirty
(30) days, ninety (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.
2.Remove oil fill cap and fill
reservoir with a quality, low
viscosity guide bar and saw
chain oil.
To prevent plastic deterioration, do not use synthetic or silicone
based oil.
Adjusting Automatic Oiler
1.From bottom of gear case, turn
adjustment screw (A) clockwise

4.Tighten spark plug to 102-153 kgf•cm (89-133 in•lbf).
Cooling System
Level 2.
Parts Required:None if you are careful.
ENGLISH
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.
2.Remove muffler cover (A).
3.Remove engine cover (B).
DO NOT use a metal scraper
to remove dirt from the
cylinder fins.
4.Use brush to remove dirt

Carburetor Adjustment
Level 2.
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 and emission compliance
above 1,100 feet ASL the carburetor may
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.
Parts Required:None
Note: Every unit is run at the factory and the carburetor is set in
compliance with emission regulations. Carburetor
adjustments, other than idle speed, must be performed by an
authorized ECHO dealer.
1.Check idle speed and reset
if necessary. If a tachometer
is available, idle speed
screw (A) should be set to
the specifications found on
“Specifications” page of this
manual. Turn idle screw (A)
clockwise to increase idle
speed; counterclockwise to
decrease idle speed.
Never try to replace or adjust guide bar and saw chain with
engine running. Always disconnect spark plug wire before

Guide Bar Cover Cleaning
1.Remove two guide bar nuts (A) and guide bar cover screw (B).
3.Gently brush debris from inside
guide bar cover and from
around sprocket.
4.Hold the bar nose up. Install
guide bar cover (C). Install the
guide bar nuts (A). Tighten the
rear nut first, then tighten the
front nut. Install and tighten the
guide bar cover screw (B).
Check bar part number on your Power Pruner. Chain and guide bar
gauge size must be identical. Use bar and chain combinations shown
in table above.
Dull or damaged cutters will result in poor cutting performance,
increased vibration, and premature saw chain failure.
ENGLISH
Always stop engine and disconnect spark plug wire before
servicing guide bar and saw chain. Always wear gloves when
filing saw chain, otherwise serious personal injury may result.
1.Set round file (A) in cutter at
30° angle. One fifth (1/5) of the
file should be exposed above
top cutter edge.
Fuel vapors are extremely flammable and may cause fire and/or
explosion. Never test for ignition spark by grounding spark plug
near cylinder plug hole, otherwise serious personal injury may
result.
STORAGE
During operation the muffler or catalytic muffler and
surrounding cover become hot. Always keep exhaust area clear
of flammable debris during transportation or when storing,
otherwise serious property damage or personal injury may
result.
