HANDHELD CHEMICAL SPRAYER SAFETY WARNINGS
Do not spray flammable liquids, such as gasoline, to reduce the risk
of fire or explosion.
Always follow the chemical manufacturer’s instructions printed on their
product labeling for use, cleaning, and storage. Chemicals should be
stored out of the reach of children.
Do not spray any material where the hazard is not known.
To reduce exposure to spray materials, wear approved safety
equipment, such as face mask designed for spraying, gloves, and
other appropriate protective equipment.
Do not use flammable solvents or abrasive cleaning agents to clean
the product.
Keep spray materials away from eyes. If spray materials come in
contact with the eyes, wash them immediately with clean water. If
irritation is still present, immediately seek medical help.
During filling and emptying power unit needs to be removed from the
tank.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Be aware of any hazards presented by the material being sprayed
and instruction to consult the markings on the container or the
information supplied by the manufacturer of the material to be
sprayed.
Keep the area clear of all bystanders, children, and pets while
spraying.
Ensure that the spray wand is securely connected to the spray wand
handle before using the product. If necessary, use pliers to attach the
spray wand to the spray wand handle.
Remember to properly replace and tighten the spray tank cover after
pouring liquid into the spray tank.
Use only consumer-grade water-based lawn and garden chemicals.
Do not use commercial-grade chemicals or chemicals for commercial
or industrial purposes.
Do not use caustic (alkali) self-heating or corrosive (acid) liquids with
the product. These can corrode metal parts or weaken the tank and
hose.
Handheld Chemical Sprayer
ENGLISH

the product. Clean after each use.
Do not pour hot or boiling liquids into the spray tank. These can
weaken or damage the hose or spray tank.
Do not overfill the tank.
Always check for leaks. If any are found, correct them before using
the product.
The spray area must be well ventilated.
Always inspect both the inside and outside of the product before each
use.
Liquids to be sprayed must be as thin as water. Thicker liquids will not

risk).
Use only System M12 chargers for charging System M12 battery
packs. Do not use battery packs from other systems.
Battery acid may leak from damaged batteries under extreme load
or extreme temperatures. In case of contact with battery acid wash
it offimmediately with soap and water. In case of eye contact rinse
thoroughly for at least 10 minutes and immediately seek medical
attention.
Warning! To reduce the risk of fire, personal injury, and product
damage due to a short circuit, never immerse your tool, battery pack
or charger in fluid or allow a fluid to flow inside them. Corrosive or
conductive fluids, such as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., can cause a short circuit.
SPECIFIED CONDITIONS OF USE
The handheld chemical sprayer is intended for outdoor use in a well-
ventilated area.
The sprayer is designed for spraying consumer-grade home and
garden chemicals such as:
• Pesticides
• Selective Herbicides
• Non-Selective Herbicides
• Insecticides
• Fungicides
• Fertilizers
• Plant Protection Treatments
This sprayer shall be used only with plant protection products
approved by local/national regulatory authorities for plant protection
products.
Do not use the sprayer with flammable liquids.
Use only substances approved for use with portable sprayers.
Do not use this product in any other way as stated for normal use.
RESIDUAL RISKS
Even when the product is used as prescribed, it is still impossible
to completely eliminate certain residual risk factors. The following
hazards may arise and the operator should pay special attention to
avoid the following:
Electric shock. Never spray liquid towards electrical sockets, cables,
or appliances.
Contact with hazardous substances. Spray materials may be harmful
if inhaled, ingested, or comes in contact with skin or eyes. Follow
instructions carefully and wear appropriate protective equipment as
prescribed in this manual.
WARNING
The vibration and noise emission level given in this information sheet has been measured in accordance with a standardized test given in EN
62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration and noise emission level represents the main applications of the tool. However if the tool is used for different applications,
with different accessories or poorly maintained, the vibration and noise emission may differ. This may significantly increase the exposure level
over the total working period.
An estimation of the level of exposure to vibration and noise should also take into account the times when the tool is switched offor when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration and/or noise such as: maintain the tool and the
accessories, keep the hands warm, organization of work patterns.

NOTES FOR LI-ION BATTERIES
Use of Li-Ion batteries
Battery packs which have not been used for some time should be
recharged before use.
Temperatures in excess of 50°C (122°F) reduce the performance of
the battery pack. Avoid extended exposure to heat or sunshine (risk
of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, the battery packs have to be fully charged,
after used.
To obtain the longest possible battery life remove the battery pack
from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C and
away from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
Battery protection for Li-Ion Akkus
In extremely high torque, binding, stalling and short circuit situations
that cause high current draw, the tool will vibrate for about 5 seconds,
the fuel gauge will flash,and then the tool will turn OFF. To reset,
release the trigger.
Under extreme circumstances, the internal temperature of the battery
pack could raise too much. If this happens, the fuel gauge will flash
until the battery pack cooled down. After the lights go off, the work
may continue.
Transport of Lithium Batteries
Lithium-ion batteries are subject to the Dangerous Goods Legislation
requirements.
Transportation of those batteries has to be done in accordance with
local, national and international provisions and regulations.
• The user can transport the batteries by road without further requi-
rements.
• Commercial transport of Lithium-Ion batteries by third parties is
subject to Dangerous Goods regulations. Transport preparation and
transport are exclusively to be carried out by appropriately trained
persons and the process has to be accompanied by corresponding
experts.
When transporting batteries:
• Ensure that battery contact terminals are protected and insulated to
prevent short circuit.
• Ensure that battery pack is secured against movement within
packaging.
• Do not transport batteries that are cracked or leak.
Check with forwarding company for further advice.
TRANSPORTATION AND STORAGE
• Remove the battery pack.
