Lithium Ion Battery Charger


The purpose of this manual is to assist you in assembling, operating and maintaining your sprayer. Please read it carefully as it furnishes information which will help you achieve years of dependable trouble-free operation.


It is recommended to charge the battery for 8-10 hours before using, or if the battery has been stored for 6 or more months without usage. Once fully charged you should be able to spray 40 gallons of fluid, or 8 consecutive tanks.

To charge the battery…

  1. Plug the charger into a 110 Volt AC electrical receptacle.
  2. Insert the plug on the opposite end of the charger into the charging jack located on the back panel of the sprayer.
  3. Reverse the above steps when charging is complete.

CAUTION: Never leave the charger connected to the battery for more the 20 hours, as this may damage the battery.


  • This sprayer is designed to be pulled or pushed by hand.
  • Pour solution into the tank and stir to mix. For liquid chemicals it is possible to mix by spraying the handgun into the tank.
  • Turn the switch to the “ON” position and spray by squeezing the lever on the handgun. The unit is supplied with a demand pump that will only operate while the lever on the handgun is depressed.

Operation Precautions

  1. Do not operate pump in an explosive environment.
    Arcing from the motor brushes, switch or excessive heat from an improperly cycled motor may cause an explosion.
  2. Do not pump gasoline or other flammable liquids. 
  3. Do not assume fluid compatibility. If the fluid is improperly matched to the pumps’ elastomers, a leak may occur.


After use fill the sprayer part way with water. Start the sprayer and allow clear water to be pumped through the plumbing system and out through the spray wand. Refill the tank about half full with plain water and use a chemical neutralizer such as Nutra-Sol® or equivalent and repeat cleaning instructions. Flush the entire sprayer with the neutralizing agent. Follow the chemical manufacturer’s disposal instructions of all wash or rinsing water.


Drain all water and chemical out of sprayer, paying special attention to pump and valves. These items are especially prone to damage from chemicals and freezing weather. The sprayer should be winterized before storage by pumping a solution of RV antifreeze through the entire plumbing. Proper care and maintenance will prolong the life of the sprayer.

WARNING:This product can expose you to chemicals including lead, which is known to the State of California to cause cancer.


Pump will not run:

  1. Check fuse next to the power switch. If blown or damaged replace with a new 5 Amp fuse.
  2. Insure the battery is fully charged
  3. Check that the on/off switch is in the on position
  4. Insure that strainer located on bottom of tank is free of debris.
  5. Insure there are NO kinks in the inlet/outlet hoses.
