• If you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Eye Protection
◆Eye protection that meets ANSI Z87.1 or CE requirements
must be worn whenever you operate the unit.
◆For additional safety, a full-face shield may be worn over
safety glasses or goggles to provide protection from sharp
branches or flying debris.
Hand Protection
Wear sturdy, no-slip, rubber work gloves to improve your grip on the
handles. Gloves also provide protection against cuts and scratches, cold
environments, and reduce the transmission of machine vibration to your
hands.
Hearing/Ear Protection
ECHO recommends wearing hearing protection whenever unit is used.
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 BAREFOOTED.
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 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.

ENGLISH
• 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.
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.

SAFETY 99944200620

• 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
ventilatedareas.Engineexhaustcontainspoisonousemissions
and can cause serious injury or death.
Read the Manuals
• 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.
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.
Avoid Hot Surfaces
• During operation, the drive shaft
housing and attachment bearing
housing may become very hot,
too hot to touch. Avoid contact
during and immediately after
operation.

OPERATION
Note: Refer to your PAS power source Operator's Manuals for
correct engine fueling, starting and stopping instructions.
Moving parts can amputate fingers or cause severe injuries.
Keep hands, clothingand loose objects away from all openings.
Always stop engine, disconnect spark plug, and make sure all
moving parts have come to a complete stop before removing
obstructions, clearing debris, or servicing unit. Allow unit to
cool before performing service.
Break-In
1. ProPaddle sweeper drums with new paddle belts must be broken-in
before use to prevent the belts from gripping and dragging on hard
surfaces.
2. Grip the handles firmly, and
position ProPaddle well out in
front of your body.
3. Run the ProPaddle at full
throttle for 3 - 5 minutes on a
rough, abrasivesurfacesuch as
worn asphalt paving. Allow the
ProPaddle's weight to fully rest
on the paddle belts.
4. After break-in, the paddle belt
fins will slide easily over the
surface being cleaned,
providing more efficient
operation on a variety of
surfaces.
Sweeping Operation
Do not operate ProPaddle with paddles close to your body,
which could result in loss of control and possible serious injury.

OPERATION 99944200620
18 X7532093907
© 1/2017 ECHO Inc.
1. Hold unit from left side, resting
sweeper paddles on work
surface.
2. Firmly grasp throttle grip with
right hand and front handle with
left hand.
3. Position ProPaddle well out in
front of your body.
4. Accelerate to full throttle and
allow paddles to push debris
ahead. Sweep to an area
where debris can be piled and
collected.
5. Debris may be swept out and
away from corners by turning
unit over to reverse paddle
direction. Grip unit securely
using both hands. Operate
throttle trigger with thumb of
right hand. For extended use,
reposition front handle to allow
comfortable grip. Return handle
to normal position for regular
operation.
Turning ProPaddle over to reverse sweeper drum rotation will
cause debris to be swept toward operator. Reduce engine
speed, and be alert for unstable footing caused by loose debris.
