Operating Instructions
Important:
Rinse the inside of the container
with cold water before use. Before using any
chemicals including herbicides, pesticides,
insecticides and weed killers etc., it is
advisable to familiarise yourself with the
sprayer operation by filling it with water and
testing the various spray patterns. Thick
mixtures can clog the spray nozzle. Solutions
of this kind should be strained and diluted to
prevent blockages. Wash the container, all
attachments and your hands thoroughly after
each use.
After Use
• Release pressure from the sprayer unit
before refilling or replacing parts. This is
done by pressing the on/off trigger and
letting out as much air or liquid as possible
through the lance and nozzle assembly.
• After you have ensured the sprayer contains
no pressure, remove the container cap
A
and empty any liquid left inside the container.
Note:
Even though the bottle may have no
liquid left inside, the actual pump chamber
may still contain residual fluid in it.
To empty the residual fluid, press and lock
the on/off trigger for continuous spraying,
then pump handle a few times and ensure
that all liquid and air is fully expelled.
• Refill the bottle with approximately 2 litres of
clean tap water, then with the on/off trigger
pressed and locked for continuous spraying,
pump handle and start expelling all the water
until empty.
• Make sure that the sprayer is not pressurised
and contains no liquid. Do not store in direct
sunlight and store out of reach of children.
Refer to detailed safety instructions
on page 3.
Important:
Ensure all caps are securely and
firmly tightened. After tightening, check that
hose and lances do not slip out.
Maintenance Advice
Over a period of time herbicides and
insecticides can leave a build up of residue
which normal cleaning will not remove. This
build up can collect around the seals and
inside the hoses and pump. If left, this build
up will eventually prevent the sprayer from
working.
To overcome this problem we recommend that
the sprayer bottle be half filled with hot (not
boiling) water from your domestic hot water
supply. By keeping the on/off trigger pressed
and locked for continuous spraying, pump
handle and start expelling all the water until
empty.
The hot water should dissolve the built up
residue and the sprayer will continue to
operate normally.
Important:
For safety, ensure you wear
protective clothing, goggles and gloves during
this operation.
Important:
If for some reason your sprayer
needs to be returned for warranty purposes,
PLEASE wash it out thoroughly to protect our
service technicians from exposure to unknown
substances.
• Refer to diagram for assembly guidance.
• Left or right-handed operation can be
achieved by changing the pump mechanism
from position
LEFT
to position
RIGHT
.
• Unscrew container cap
A
and fill liquid to
the required level. Ensure that filter is sitting
inside bottle as shown on diagram.
DO NOT exceed the 16L mark on the 16L
Knapsack Sprayer.
• Replace container cap
A
and tighten firmly
by hand. Make sure that the other container
cap is also tight to prevent air escaping
during use.
• Firmly screw Lance Assembly
D
to the
Handle Assembly
C
.
• Adjust straps for comfort.
• Pump handle
B
and start spraying by
pressing the on/off trigger on handle
assembly
C
. The handle assembly is
equipped with a lock for continuous
spraying. Press trigger and slide it forward
until locked. To unlock, slide the trigger back
and release it.
• Pump handle periodically to maintain
pressure for ongoing spray flow.
• Adjust the twin nozzles for required spray
pattern. To use only single nozzle, replace
any of the two outside nozzles with the
centre nozzle cap.
