Breathing Protection
Operators who are sensitive to dust or other common airborne allergens
may need to wear a dust mask to prevent inhaling these materials while
operating unit. Dust masks can provide protection against dust, plant debris,
and other plant matter such as pollen. Make sure the mask does not impair
your vision, and replace the mask as needed to prevent air restrictions.
Proper Clothing
Wear snug-fitting, durable clothing:
• Pants should have long legs, shirts should have long sleeves.
• DO NOT WEAR SHORTS.
• DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or
hanging items that could become entangled in moving parts or
surrounding growth.
• Keep clothing buttoned or zipped, and keep shirt tails tucked in.
Wear sturdy work shoes with nonskid rubber soles.
• DO NOT WEAR OPEN TOED SHOES.

• DO NOT OPERATE UNIT WITH BARE FEET.
Keep long hair away from engine and air intake. Retain hair with cap or net.
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 can 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 and Extreme Conditions
Prolonged exposure to cold and/or vibration can result in injury.
Read and follow all safety and operation instructions to
minimize risk of injury. Failure to follow instructions can 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 99944200532

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 can result.

Guide Bar and Saw Chain
Serious injury may result from the use of non approved
guide bar and saw chain combinations. Read and comply
with all safety instructions listed in this manual.
ECHO, INC. will not be responsible for the failure of cutting
devices or accessories which have not been tested and
approved by ECHO for use with this unit.
• Never adjust the guide bar or saw chain when the engine is operating.
• Check that the cutting attachment, guide bar and saw chain is firmly
attached and in safe operating condition.
• Only use ECHO approved guide bar and saw chain.
• Do not hit rocks, stones, tree
stumps and other foreign objects
with the saw chain.
• Do not cut into the ground with
the saw chain.
• If saw chain strikes an
obstruction, stop engine
immediately and inspect saw
chain for damage.
• Do not operate with a dull, broken or discolored saw chain.
• Remove all foreign objects from work area.
• Always cover the guide bar and saw chain with guide bar cover during
transportation and in storage.
Read the Manuals
• Provide all users of this equipment with the Operator’s 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.
SAFETY 99944200532

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 pole pruner 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 pole pruner 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 pole
pruner and result in serious injury to the operator or any one
standing close by. Hold the pole pruner 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.
99944200532 SAFETY
X7702092208 13
© 03/24 ECHO Inc.
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 pole pruner
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.
If the saw chain does strike a foreign object, immediately stop the engine,
inspect and repair the pole pruner if necessary.
Equipment
Use this attachment with ECHO approved models only. Serious
injury may result from the use of this attachment combined with
a non approved ECHO product.
Check unit for loose/missing nuts, bolts, and screws.
Tighten and/or replace as needed.
Inspect ProPaddle sweeper drums for damage and that
they are firmly secured in place. Replace paddles of
damaged or worn excessively.
Check that the ProPaddle attachment is firmly attached and
in safe operating condition.
Note: ECHO, INC. will not be responsible for the failure of cutting
devices, attachments or accessories which have not been
tested and approved by ECHO.

Filing Standard Saw Chain
Level 2
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.
Always stop unit and disconnect spark plug wire, or remove
battery before servicing guide bar and saw chain. Always wear
gloves when filing saw chain, otherwise serious personal injury
may result.
1. Use a 4.5 mm round file for a 0.043 in. gauge saw chain. Use a
5/32 in. round file for 0.050 in. gauge saw chain.
