Original Instructions
IMPORTANT!
It is essential that you read the instructions
in this manual before assembling, operating,
and maintaining the product.
Subject to technical modication.
Safety, performance, and dependability have
been given top priority in the design of your
cordless blower.
INTENDED USE
The cordless blower is intended only for
outdoor use, in dry, and well-illuminated
conditions.
The product is not intended to be used by
children or persons with reduced physical,
mental, or sensory capabilities.
The product is designed for blowing light
debris, such as leaves, grass, and other
garden waste.
Do not use the product for any other purpose.
GENERAL SAFETY WARNINGS
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, re,
and/or serious injury. Save all warnings and
instructions for future reference.
WARNING! Never allow children or people
who are unfamiliar with these instructions to
use the product. Local regulations may restrict
the age of the operator.
TRAINING
■Read the instructions carefully. Be familiar
with the controls and the correct use of the
product.
■Keep in mind that the operator or user
is responsible for accidents or hazards
occurring to other people or their property.
■Do not use the product while tired, ill, or
under the influence of drugs, alcohol, or
medication.
PREPARATION
■Some regions have regulations that restrict
the use of the product to some operations.
Check with your local authority for advice.
■Wear hearing protection at all times whilst
operating the product. This will prevent
exposure to noise that could cause a
permanent hearing injury. Protection such
as ear plugs can limit your exposure and
reduce noise.
■Wear full eye protection at all times while
operating the product. Wear a full face
mask or fully enclosed goggles. Normal
spectacles or sunglasses are not adequate
protection. Objects can be thrown at high
speed by the powerful air jet at any time and
may rebound from hard surfaces toward the
operator.
■While operating the product, always wear
substantial footwear and long trousers.
Do not operate the product when barefoot
or wearing open sandals. Avoid wearing
clothing with loose fitting or that has hanging
cords or ties.
■Do not wear loose clothing or jewellery that
can be drawn into the air inlet. Secure long
hair so it is above shoulder level to prevent
entanglement in moving parts.
■Before each use, ensure that all controls
and safety devices function correctly. Do
not use the product if the off switch does not
stop the product.
■Operate the product in the recommended
position and only on a firm and level surface.
■Do not operate the product on a paved or
gravel surface where ejected material could
cause injury.
■Before each use, always inspect the housing
for damage. Ensure that guards and handles
are in place and properly secured. Replace
worn or damaged components in sets to
preserve balance. Replace damaged or
unreadable labels.
■Never operate the product while people,
especially children, or pets are nearby.
■Keep all cooling air inlets clear of debris.
■Use rakes and brooms to loosen debris
before blowing.
■Clear the work area before each use.
Remove all objects such as rocks, broken
glass, nails, wire, or string that can be blown
a considerable distance by high velocity air.
■Injuries may be caused or aggravated by
prolonged use of a tool. When using any
tool for prolonged periods, ensure you take
regular breaks.
BATTERY TOOL USE AND CARE
■Recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a
risk of fire when used with another battery
pack.

3
Original Instructions
■Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
■When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small
metal objects that can make a connection
from one terminal to another. Shorting the
battery pack terminals together may cause
burns or a fire.
■Under abusive conditions, liquid may be
ejected from the battery pack; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery pack may cause irritation or burns.
■Do not use a battery pack or tool that
is damaged or modified. Damaged or
modified batteries may exhibit unpredictable
behaviour resulting in fire, explosion, or risk
of injury.
■Do not expose a battery pack or tool to fire
or excessive temperatures. Exposure to fire
or excessive temperature above 130°C may
cause explosion.
■Follow all charging instructions and do not
charge the battery pack or tool outside
the temperature range specified in the
instructions. Charging improperly or at
temperatures outside the specified range
may damage the battery and increase the
risk of fire.
OPERATION
■Operate the product only at reasonable
hours—not early in the morning or late at
night when people might be disturbed.
■Never operate the product in an explosive
atmosphere.
■Avoid using the product in bad weather
conditions, especially when there is a risk
of lightning.
■Keep bystanders, children, and pets 15 m
away from the area of operation. Stop the
product if anyone enters the area.
■Do not operate the product in poor lighting.
The operator requires a clear view of the
work area to identify potential hazards.
■Operating similar tools nearby increases
both the risk of hearing injury and the
potential for other persons to enter your
working area.
■Always be sure of your footing on slopes.
Walk, never run.
■Keep proper footing and balance. Do not
overreach. Overreaching can result in loss
of balance.
■Never use the product with defective guards
or shields, or without safety devices in place.
■To reduce the risk of injury associated with
contacting rotating parts, always turn off the
product and remove the battery pack. Make
sure that all moving parts have come to a
complete stop:
●before leaving the product unattended
●before clearing blockages
●before checking, cleaning, or working on
the product
●before inspecting the product after
striking a foreign object
●whenever the product starts to vibrate
abnormally (inspect immediately)
■Immediately turn off the product and remove
the battery pack in the event of accident
or breakdown. Do not operate the product
again until it has been fully checked by an
authorised service centre.
■Do not modify the product in any way or
use parts and accessories that are not
recommended by the manufacturer.
■If the product is dropped, suffers heavy
impact, or begins to vibrate abnormally,
immediately stop the product and inspect
for damage or identify the cause of the
vibration. Any damage should be properly
repaired or replaced by an authorised
centre.
BLOWER SAFETY WARNINGS
■Wear a face filter mask in dusty conditions
to reduce the risk of injury associated with
the inhalation of dust.
■Slightly dampen surfaces in dusty
conditions.
■Do not use the product near open windows.
■Use the full blower nozzle extension so that
the air stream can work close to the ground
and perform effectively.
■Do not point the blower nozzle in the
direction of people or pets.
■Never place objects inside the blower tubes.
■Do not place the product on top of or near
loose debris. Debris can be sucked into the
intake vent, resulting in possible damage to
the product.

WARNING! The declared vibration total
values and the declared noise emission values
given in this instruction manual have been
measured in accordance with a standardised
test and may be used to compare one tool with
another. They may be used for a preliminary
assessment of exposure.
The declared vibration and noise emission
values represent the main applications of the
tool. However, if the tool is used for di󰀨erent
applications, used with di󰀨erent accessories,
or poorly maintained, the vibration and noise
emission may di󰀨er. These conditions may
signicantly increase the exposure levels over
the total working period.
An estimation of the level of exposure to
vibration and noise should take into account
the times when the tool is turned o󰀨 or when
it is running idle. These conditions may
signicantly reduce the exposure level over the
total working period.
Identify additional safety measures to protect
the operator from the e󰀨ects of vibration and
noise, such as maintaining the tool and the
accessories, keeping the hands warm (in case
of vibration), and organising work patterns.
