■ Liquids to be sprayed must be as thin as water. Thicker
liquids will not spray properly.

spray tank using a funnel, if necessary.
■ Wear proper protective clothing and equipment when
using, filling, and cleaning the sprayer. Follow the
chemical manufacturer’s instructions with respect to
protective equipment.
■ Immediately change work clothes contaminated with
plant control chemicals.
■ Wear full eye protection while operating the product. If
you are spraying overhead, wear impermeable head
covering.
■ Do not use the product when you are tired, ill, or under
the influence of alcohol, drugs, or medication.
NOTE: When using a measuring container other than the
measuring cup, or when using a funnel to fill the tank,
thoroughly clean and rinse these items after use. When
premixing spray materials, rinse the container used for
mixing.
■ Do not spray where spark, flame, or other source of
ignition is present.
■ Do not spray in the direction of people or animals.
Always spray downwind.
■ Do not smoke, eat, or drink while using the product.

■ Do not let the spray materials come in contact with skin.
If contact does occur, wash immediately with soap and
plenty of water.
■ Aim the nozzle directly at the plants or objects you
intend to spray.
■ Ensure that the spray materials are directed at an area
that will not be damaged by the spray materials.
■ Avoid spraying on windy days. The spray materials can
be accidentally blown onto plants or objects that should
not be sprayed.
■ 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.
■ Electric shock hazard. Do not spray towards electrical
outlets.
■ Immediately turn off and remove the battery pack in
the event of accident or breakdown. Don’t operate
the product again until it has been fully checked by an
authorised service centre.
■ If there is no spray coming out from the nozzle or the

may be blocked. Rinse and clean all parts of the hose
and wand system (spray gun, filter in tank, spray wand,
hose) with clean water.
■ After long time storage or after winter, spray the
backpack sprayer with clean water. Check if there is
any leakage or crack.
■ Maintain the product. Thoroughly inspect both the
inside and outside of the product and examine the
components before each use. Check for cracked
and deteriorated hoses, leaks, clogged nozzles, and
missing or damaged parts. If damaged, have the
product repaired before use. Many accidents are
caused by poorly maintained products.
■ Remove the battery from the product before draining,
cleaning, or storing to avoid accidental starting.
MIXING THE SPRAY SOLUTION
WARNING
Mix the chemicals strictly in accordance with the
manufacturer’s instructions. Incorrect mixtures may
produce toxic fumes or explosive solutions.
■ Never spray liquid plant control chemicals undiluted.
■ Prepare solution and fill the container outdoors only or
in well-ventilated locations.
■ Prepare only sufficient solution for the job at hand so
that nothing is left over.
■ Do not mix different chemicals unless such mixture is
approved by the manufacturer.
FILLING THE CONTAINER
■ Stand the sprayer on a level surface, do not fill the
container above the maximum mark.
■ When filling from the central water supply, do not
immerse the end of the hose in the solution. Sudden
low pressure in the system may cause the solution to
be sucked back into the water supply.
■ Before filling the container with spray solution, carry out
a test run with fresh water, and check all parts of the
sprayer for leaks.
■ After filling, fit the filler cap, and tighten it down firmly.
■ Hang a tag to the product to note what chemical is
being used.
APPLICATION
■ Work only in the open or in well-ventilated locations,
e.g. open greenhouses.
■ Never blow through nozzles or other components by
mouth.
■ Avoid contact with plant control chemicals, immediately
change clothing contaminated with plant control
chemicals.
■ Do not spray in windy conditions.
■ Too high or too low pressure or unfavorable
weather conditions can result in the wrong solution
concentration. Overdosing may damage plants and the
environment. Underdosing may result in unsuccessful
plant treatment.
■ To reduce the risk of damage to the environment and
plants, do not operate the sprayer:
● when pressure is too high or too low
● in windy conditions
● in direct sunlight
■ To reduce the risk of accidents and damage to the
sprayer, never operate the sprayer with:
● flammable liquids
