General safety instructions
WARNING: Read the
warning instructions that
follow before you use the
product.
•Incorrect or careless use of
the product can turn it into a
dangerous tool that can cause
serious or even fatal injury to
the operator or others. You
must read and understand the
contents of this operator's
manual.
•Under no circumstances may
the design of the product be
modified without the
permission of the
manufacturer. Never use a
product that has been
modified in any way from its
original specification and
always use original
accessories. Non-authorized
modifications and/or
accessories can result in
serious personal injury or the
death of the operator or
others. Your warranty may not
cover damage or liability
caused by the use of non-
authorized accessories or
replacement parts.
•This product produces an
electromagnetic field during
operation. This field may
under some circumstances
interfere with active or passive
medical implants. To reduce
the risk of serious or fatal
injury, we recommend persons
with medical implants to
consult their physician and the
6790 - 001 - 05.12.2018

medical implant manufacturer
before operating this product.
•Remove the battery from the
product during charging.
Safety instructions for
operation
WARNING: Read the
warning instructions that
follow before you use the
product.
•If you encounter a situation
where you are uncertain how
to proceed you should ask an
expert. Contact your dealer or
your service workshop. Avoid
all usage which you consider
to be beyond your capability.
•Do not allow children to use or
be in the vicinity of the
product. Since the product is
easy to start, children may be
able to start it if they are not
kept under full surveillance.
This can mean a risk of
serious personal injury.
Disconnect the battery when
the product is not under close
supervision.
•Ensure that no people or
animals come closer than 15
meters (50 ft.) while you work.
When several operators are
working in the same area the
safety distance should be at
least 15 meters. Otherwise
there is a risk of serious
personal injury. Stop the
product immediately if anyone
approaches. Never swing the
product around without first
checking behind you to make
sure that no one is within the
safety zone.
•Make sure that you can move
and stand safely. Check the
area around you for possible
obstacles (roots, rocks,
branches, ditches, etcetera) in
case you have to move
suddenly. Take great care
when you work on sloping
ground.
•Keep a good balance and a
firm foothold at all times. Do
not overreach.
•Listen out for warning signals
or shouts when you wear
hearing protection. Always
remove your hearing
protection as soon as the
product stops.
•Show consideration to persons
in your surroundings by
avoiding using the product at
unsuitable times, such as late
in the evening or early in the
morning. Follow local
regulations and ordinances.
•Use the product with the
lowest possible airflow. It is
790 - 001 - 05.12.2018 7

seldom necessary to use full
airflow, and many work
procedures can be done at
half airflow. A lower airflow
means less noise and less
dust, and it is also easier to
keep control over the rubbish
collected together/moved.
•Use a rake or a brush to
release rubbish stuck to the
ground.
•Hold the opening of the blower
as close to the ground as
possible.
•Observe your surroundings.
Direct the product away from
persons, animals, play areas,
cars etc.
•Minimize the blowing time by
lightly wetting dusty areas or
using spray equipment.
•Be aware of the wind direction.
Work with the wind to make
your work easier.
•Stop the product and remove
the battery if the product starts
to vibrate abnormally.
•Using the product to move
large piles is time consuming
and creates unnecessary
noise.
•Clean up afterwards. Make
sure that you have not blown
rubbish into someone's
garden.
•Do not run with the product.
•The powerful currents of air
can move objects at such a
speed that they can bounce
back and cause serious eye
injuries.
•Do not direct the airflow
towards people or animals.
•Stop the motor before you
assemble or dismantle
accessories or other parts.
•Keep all parts of your body
away from hot surfaces.
•Never put the product down
when it is activated unless you
have it in clear sight.
•The product must not be used
while on a ladder or
scaffolding.
•Do not use the product unless
you are able to call for help in
case of an accident.
8790 - 001 - 05.12.2018

•Watch out for thrown objects.
Stones, rubbish, etc., can be
thrown up into the eyes
causing blindness or serious
injury.
•Use a residual-current device
(RCI) for increased security. A
residual-current device is fitted
to protect operators in case an
electrical fault should occur.
•This product is renowned for
its low vibration load.
Overexposure to vibration can
lead to circulatory damage or
nerve damage in people who
have impaired circulation.
Contact your doctor if you
experience symptoms of
overexposure to vibration.
Such symptoms include
numbness, loss of feeling,
tingling, pricking, pain, loss of
strength, changes in skin color
or condition. These symptoms
normally appear in the fingers,
hands or wrists.
•Only use the product for the
purpose it was intended for.
•It is not possible to cover
every conceivable situation
you can face. Always exercise
care and use your common
sense. Avoid all situations
which you consider to be
beyond your capability. If you
still feel uncertain about
operating procedures after
reading these instructions, you
should consult an expert
before continuing.
•The harness must always be
worn when working with the
product. Failure to do so
means you will be unable to
manouevre safely and this can
result in injury to yourself
and/or others.
Personal protective
equipment
WARNING: Read the
warning instructions that
follow before you use the
product.
•Always use approved personal
protective equipment when
you use the product. Personal
protective equipment cannot
fully prevent injury but it
decreases the degree of injury
if an accident does occur. Let
your dealer help you select the
right equipment.
•Long term exposure to noise
can result in damaged
hearing. In general, battery
powered products are
relatively quiet but damage
can result from a combination
of noise level and long usage.
recommends that operators
use hearing protectors when
790 - 001 - 05.12.2018 9

using products for a longer
coherent time of a day.
Continual and regular users
should have their hearing
checked regularly. Note that
hearing protectors limit the
ability to hear sounds and
warning signals.
•Use approved eye protection.
If you use a visor, you must
also use approved protective
goggles. Approved protective
goggles must comply with the
ANSI Z87.1 standard in the
USAs or EN 166 in EU
countries.
•Use clothing made of a strong
fabric. Always use heavy, long
pants and long sleeves. Do
not use loose clothing that can
catch on twigs and branches.
Do not wear jewelry, short
pants, sandals or go with bare
feet. Put your hair up safely
above shoulder level.
•Keep first aid equipment close
at hand.
•A breathing mask should be
used when there is a risk of
dust.
