  Before inserting the battery cartridge into the tool, always check to see that the tool is switched off.

Spraying

• 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.

1. Switch

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

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

• 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
	Dilution ratio
Water	500	1,000	2,000
4 L	8 mL	4 mL	2 mL
6 L	12 mL	6 mL	3 mL
8 L 10 L	16 mL 20 mL	8 mL 10 mL	4 mL 5 mL
12 L	24 mL	12 mL	6 mL
15 L	30 mL	15 mL	7.5 mL

Chemical replenishment

• 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.

MAINTENANCE

• 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.
• Now fill up chemical tank with clean water and run the sprayer for 2 to 3 minutes to wash out residual chemical from the pump, hose, and nozzle, etc.
• Remove the residual liquid from inside the chemical tank, restart the pump, and run the sprayer until residual liquid ceases to come out of the nozzle, and then turn sprayer switch OFF.
• Wipe away moisture and dirt from equipment, and then check for damage and leaks.

Daily checks

• Before work, check to see whether or not fastened units are loose and components are missing.
• Check to make sure the spray hose is not cracked, worn and/or damaged.
• After use, always be sure to wipe dirt off of exterior, and to check for damage and/or leaks.

Cleaning water absorption strainer

After removing chemical from tank, remove the water absorption strainer at the bottom of the tank, and clean it.

1. Water absorption strainer

Cleaning lever cock strainer

Remove lever cock cap and clean strainer.

1. Lever cock cap
2. Strainer

NOTE:
Water absorption strainer

• This is a filter used to prevent dirt and dust (that for some reason has got passed the tank strainer into the tank) from getting into the pump. If the water absorption strainer becomes blocked, spraying will deteriorate, and there is a risk of the pump being adversely affected.

Lever cock strainer

• Spraying deteriorates if the lever cock strainer becomes blocked.

Sprayer storage

• Wash the equipment using the after-use maintenance procedures.
• In particular, when storing during the winter season, breakdown or damage may occur due to freezing of residual chemical and/or washing water in the pump. Run the pump until all residual liquid has exited from the nozzle, check to make sure there is no more residual liquid, turn the sprayer switch OFF, and then store the sprayer away.

Store the Garden Sprayer out of reach of children, in an indoor locale that does not freeze, is away from direct sunlight, and has good ventilation.

• Take full care in storing the sprayer, as, in some cases, the plastic components will deteriorate markedly if left in direct sunlight for a prolonged period; moreover, product caution labels will discolor and/or come off.
