Important Points for Set-Up
A WARNING
When you need to attach an engine to this product, please ask your nearest dealer to handle
it.
When operating with a V-pulley and V-belt or similar set-up, make sure to cover the rotating
parts and arrange the equipment so those parts are difficult to come into contact with even
when checking their operation.
(Leave the cover on both during operation and while checking operation. If a belt cover cannot be
attached, then make sure to take other measures, such as putting up a fence around the Machine)
Make sure to turn the machine OFF before Inspecting ¢ or adjusting it.
[Áh CAUTION |
Set-up the power sprayer for use within the specifications for crankshaft speed, pressure, and
liquid volume.
Using the equipment outside the specified ranges may damage the power sprayer or result in
accidents. |
Use an engine with a rated power output that is equal to or higher than the power required by the
sprayer. When the engine power is equal to or lower than the power required by the Sprayer, the
sprayer may not achieve full performance.
Set up the power sprayer so that the oil gauge is easy to check.
CAUTION
For fixed installation of the power sprayer, use bolts of the proper size and quality, and tighten
them firmly.
Unstable installation of the power sprayer and engine will result in vibration that can have a bad effect
on the power sprayer. |
Select a proper size V-puliey and V-belt suitable for the power required.
Use a V-pulley with shaft bore and keyslot dimensions suited to the shaft.
A loose V-pulley bore or keyslot can result in harmful vibration and cause accidents, so be sure to use
the proper size.
Attach the V-pulley so the end of the shaft does not quite reach the face of the pulley, and tighten the
bolt securely, using a washer. When necessary, use a setscrew on the V-pulley.
Align the engine and the power sprayer so their V-pulleys are in a straight line.
The V-belt will come under excessive strain if it is not in a straight line when viewed from above,
causing possible dislocation or damage to the belt.
Make sure the V-belt is neither too loose nor too tight.
If the belt is too tight, it may damage the bearing.
If it is too loose, it may cause slipping, belt damage, or dislocation.
When using two or more V-belts, make sure they are the same type and circumference.
When replacing a V-belt, replace all of them at the same time.
Important Points for Set-Up
[4h DANGER
* Use screws of the same type and size to attach hoses and nozzles, and attach them securely,
always using gaskets.
The use of screws of an improper size or type, lost or damaged gaskets, and loose screws can result
in exposure to chemicals. Over-tightening screws can cause gaskets to protrude or be damaged,
also resulting in exposure to chemicals. Therefore, be sure to tighten screws properly.
Be sure to check operation with plain water before mixing in chemicals.
SUCTION
* The suction hose diameter should be determined by the suction port diameter. When the pipe
diameter is narrowed by valves or other devices, use a suction hose that is one size larger.
CAUTION
Narrowing down the suction hose diameter unnecessarily can cause deterioration of performance and
accidents.
Keep the suction intake lifting height within 3 m.
SPRAYING
e Select sprayer hose that can handle the operating pressure.
HOSES
e Make sure that the suction hose and overflow hose are inserted well into the tank and fix them in
place securely with a strap.
» When connecting a hose, always make sure there is a gasket in place.
A WARNING
Attach only an overflow hose to the overflow port. Be absolutely sure not to attach any stopcock
or valve and block the overflow completely, in particular, because this can wreck the machine
and possibly cause injury.
NOZZLES
* Select nozzles with a delivery rate that assures an overflow volume of about 30%.
|dà DANGER
e Using nozzles not suited to the pump specifications, removing standard equipment from the
sprayer, or forcing the operation or handling of the sprayer, can not only keep the sprayer
from putting out full performance but may cause malfunctions or in some cases even damage
and injury. Therefore, be absolutely sure to avoid this kind of use.
|) CAUTION
* Never point the nozzle toward a person, since it may expose the person to chemicals.

3. Handling and Operation
Preparation & Inspection ~ Spraying
CAUTION
This power sprayer does not come with oil in it. Be
sure to fill with oil before using it.
» Fill with oll (SAE 10W-30 equivalent, SC classification
or better) until the level comes up inside the red circle
on the oil gauge at the rear of the pump or until the
level comes up into the area between the line marks on
the oil gauge on the side of the pump.
» Put 3-5 drops of oil (SAE 10W-30 equivalent) into each
of the three holes (lubricating ports) at the top front of
the crankcase.
|) CAUTION
Check to be sure gaskets are used when attaching the
suction hose and overflow hose. Lack of a gasket on
the suction hose, in particular, can cause equipment
vibration and suction problems that may shorten pump
life.
« When a sirainer is required, use the one that comes
with the sprayer as a standard accessory. (Please
check with the nearest dealer or with this company's
sales office before using any other strainer.)
Preparation & Inspection ~ Spraying
* When starting to use the sprayer, test it first with plain water
to make sure the sprayer is operating normally.
[AA CAUTION
If the power sprayer operates abnormally in any way, turn
it off immediately and refer to the troubleshooting section
on pages 13-14 to diagnose and resolve the problem.
e When inserting the suction hose in the chemical tank, set it
so that the lifting height is within 3 m.
| CAUTION
It can be dangerous if the suction hose or overflow hose
thrash around out of control, so use the provided strap
« Check to be sure that the strainer is inserted completely into
the liquid in the tank.
e Lift up the lever on the pressure regulator valve to the Start
position as shown in the illustration.
Turn the knob to align the "0" point with the indicator.
CAUTION
Be careful not to start running the sprayer with positive
pressure, since running it when there is nothing to pump
can damage the piston packing.

Preparation & Inspection ~ Spraying ~ Stopping
| * * Be sure to attach the belt cover when starting and operating
the equipment.
A WARNING
Rotating parts can cause accidents when objects are
caught up in them, so always make sure that the belt cover
is attached. If a cover cannot be attached, then be sure to
take other measures, such as putting up a fence around the
machine. ВЕ
e Turn the lever on the pressure regulator valve down to the
Run position.
CAUTION
Make absolutely sure that there is suction at this point. If
the sprayer runs for one minute or more without anything
to pump (running empty) after starting, it will damage the
piston packing. In this case, stop the sprayer and refer to
the troubleshooting section on pages 13-14 to diagnose
and resolve the problem, then try again.
* Turn the knob to align the desired pressure value with the
indicator.
| à CAUTION
When more than one person is working, they should signal
each other in advance whenever opening the main cocks.
This is because the sudden rise in pressure can backlash
on anybody holding a nozzle, and this is dangerous.
Stopping
e In order to stop the pump, turn the pressure regulator knob to
"0" and return the lever on the pressure regulaior valve to the
Start position.
The pressure regulator operates using a compression spring.
If there is still pressure inside any hose, the remaining liquid
may spurt out when disconnecting the hose.
4. Cleaning, Maintenance, and Storage
* When finished working, let the pump take in plain water to
flush out any chemicals remaining inside and clean it.
This helps prevent problems when starting the pump up for
the next work season.
CAUTION
When handling the water used to flush out the equipment,
_ take the same careful precautions to avoid damage and
exposure that you would when working with the chemicals
themselves.
- Carefully read the handling and safety instructions for the
chemicals to learn how to handie them properly.
* Hemove the nozzles from the hoses and lift the suction
strainer out of the water, then run the sprayer at low speed
with the main cocks open to drain it.
(Set the pressure regulator knob to "0" and turn the lever to
Start.)
CAUTION
To protect the equipment, do not run it empty for any
longer than a minute at most.
Cleaning, Maintenance, and Storage
«Be sure tó disconnect the suction hose and overflow hose,
because leaving them attached will damage the gaskets,
which can cause problems. The disconnected suction and
overflow hoses should be stored properly. |
eStore the equipment without any tension on the compression
spring. ln order to maintain the accuracy of the pressure
“values on the knob, the knob should be turned to "0" and the
lever on the pressure regulator valve should be put at the Start
position.
» Drain all liquids from the equipment completely before storing
to protect if from freezing damage during the winter.
Specifically, loosen the drain plug as shown in the illustration
and completely drain ali liquid from inside the unit. Then clean,
maintain, and store the equipment.
| Л CAUTION
Make sure the oil has cooled down before draining it.
* Make absolutely sure that the equipment has stopped working
before starting to change the oil. |
e The first oil change should be made after 50 hours of
operation. From the second time on, change the oil after
every 100 operating hours.
Oil breaks down, so it should be changed (SAE 10W-30
equivalent, SC classification or better) at least once a year
even if the equipment is operated for fewer hours than
indicated above.
