How to use lever cock
Fig.3
1. Position "A" is the STOP position.
2. Position "B" is the spray position. Release the
lever, and it will return to position "A" and spraying
will stop. (Intermittent spraying)
3. Position "C" is the continuous spray position.
(Continuous spraying)
NOTE:
Check to make sure the tank is loaded with
•
chemical or clean water when operating the sprayer,
as continued operation of the sprayer with an
empty tank may burn out the pump.
Running the sprayer for prolonged periods with the
•
lever cock closed may have an adverse effect on
the pump as well as drain the battery. Be sure to
turn sprayer switch OFF whenever possible.
If spray splutters, or pumps suddenly screeches,
•
the chemical tank is empty, so immediately turn
sprayer switch OFF.
Do not spray with the battery cover open and/or with
•
the back-support cushioning removed, as there is a
risk of damage to electrical system. Moreover, do not
spray pointing the spray nozzle at the sprayer.
Do not forcibly handle the lever cock and/or the
•
spray pipe.
Mixing chemical
CAUTION:
Never use Kelthane water dispersible powder
•
(acaricide) because it tends to harden due to heat
generated by pump during operation, which causes
the pump to stop. Use a Kelthane emulsion, Akar
emulsion or Osadan water dispersible powder as
the acaricide.
When using a water dispersible powder or lime
•
sulfur, be sure to dissolve well prior to use.
Take maximum care when handling chemicals.
•
Wash away thoroughly if chemical comes into
contact with body.
Chemicals are harmful. Always adhere to chemical
•
manufacturer instructions when handling chemicals.
See the following chart for ratio information that is
•
useful when diluting chemicals.
Never spray chemicals undiluted.
•
When using a water dispersible powder, etc.,
•
dissolve thoroughly in a container such as a bucket.

Chemical replenishment
WARNING:
When changing chemical, be sure to carefully wash
•
the tank, pump, and nozzle, etc. with clean water.
Residue of the previous chemical may cause a
spray injury. Moreover, if chemicals mix, a chemical
change may occur, with the danger of generating a
toxic gas.
Be sure to wear protective gloves.
•
Do not change chemical in poorly ventilated locale.
•
(prevent chemical poisoning)
Check to make sure the sprayer switch is OFF and
replenish chemical tank with mixed chemical.
When filling tank with chemical, always strain chemical
through equipped tank strainer.
The side of the chemical tank is marked with scale
divisions, so be sure to use these as operation guidelines.
Firmly tighten chemical tank lid to prevent leaking.
Back strap adjustment
Adjust back strap to a length that brings the sprayer as
close to the body as feasibly possible.
Lengthening strap
(1) Lift up buckle.
(2) Pull the belt on the side connected to the
sprayer.
Fig.4
Shortening strap
Pull the belt on the free side.

NOTE:
When shortening the strap, it will move relatively easily if
there is no weight exerted on the strap.

Always be sure that the tool is switched off and the
•
battery cartridge is removed before attempting to
perform inspection or maintenance.
For inspection and maintenance, always wear
•
protective gloves.
Never use gasoline, benzine, thinner, alcohol or the
