Read on to learn more about why the Wheelbarrow is taking the spraying world by storm!

As with our other sprayers, most of the ‘heavy lifting’ was done at the warehouse or factory before it even arrives to you! Basic tools like a pair of pliers, and a Philips screwdriver will speed things up, and our starter guide video, found on will have you up & running in less than 20 minutes.

Replacing the Battery

The battery and high-pressure pump are located next to each other, under the black plastic cover. They are both user-serviceable parts available from customer support, or our website  If you’ve determined that your battery will no longer hold a charge, or it needs frequent charges to function, it may have reached the end of its service life. Ensure that the charger and wall outlet are both functioning properly before changing the battery.

  • Turn the unit off with the red rocker switch (O=Off). Ensure the battery charger is NOT plugged in.
  • Remove the black plastic battery/pump compartment cover. It is held in place with 6 Philips screws. Four of them are located on the top of the cover, in each corner, and two of the screws are above the red on/off rocker switch. You will not need to remove the 2 screws on either side of the voltmeter.
  • Lift up on the black cover. Place in a safe place to avoid damage.
  • There is a black metal bracket holding the battery in place. This is held in place with a clip which you’ll need to remove.
  • Next, remove the two black (-) wires by unthreading the nuts on the negative battery terminal.
  • Remove the red (+) wire from the positive red terminal. Do not allow a tool to make a connection between the two terminals!
  • Lift old battery out of compartment and dispose of it as recommended in your area. It is a lead-acid type battery & should NOT be thrown in trash receptacles.
  • Place the new battery with red (+) terminal towards the back of unit, just like the old battery. Reattach the red wire with the nut/bolt. Reattach the black wires with nut/bolt. Replace black battery retaining bracket with nut/bolt.
  • Install black battery cover, and screw 6 Philips screws back in to frame.
