OPERATION
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the tool is switched off.
Spraying
CAUTION:
• To prevent sudden spraying, be sure to set the lever
cock to STOP, before turning sprayer switch ON or
OFF.
• When spray work is interrupted, be sure to turn switch
OFF, to prevent inadvertent spraying. (Fig. 4)
Be sure to check the situation of surroundings before
turning sprayer switch ON.
Operate lever cock to spray.
Once spraying is complete, immediately set lever cock to
STOP, and then turn sprayer switch OFF.
How to use lever cock (Fig. 5)
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. 6)
Shortening strap
Pull the belt on the free side. (Fig. 7)
NOTE:
When shortening the strap, it will move relatively easily if
there is no weight exerted on the strap.
MAINTENANCE
CAUTION:
• 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
like. Discoloration, deformation or cracks may result.
After-use maintenance
• After use, remove residual liquid from chemical tank,
and wash away clinging chemical from inside of tank
using clean water.
