If your battery has flashing red indicator lights, this means the battery is no longer functional and will not hold a charge. A new battery will have to be purchased. If you are within the warranty period, fill out the warranty form below to request a replacement.
If all the indicator lights on the battery are flashing when plugged into a charger, the battery is being connected to the wrong charger. Check to make sure the charger you are using is the original FlowZone® charger included with your sprayer.
Using the incorrect charger or a third-party charger will cause damage to your battery. The 18V/2.6Ah Battery (FZAAEN) should only be charged with the 21V/1A Charger (FZAAEP). The 18V/5.2Ah Battery (FZAAEM) should only be charged with the 21V/2.5A Charger (FZAAEL).
Refer to the video above for best practices when it comes to your sprayer's lithium-ion battery. In general, it is important to remember the following:
Always fully charge the battery to 100% before the first use.
Always use FlowZone® branded chargers
Make sure the charger is compatible with your battery. The 18V/2.6Ah Battery (FZAAEN) should only be charged with the 21V/1A Charger (FZAAEP) , while the 18V/5.2Ah Battery (FZAAEM) should only be charged with the 21V/2.5A Charger (FZAAEL).
Charge your battery whenever it reaches three bars or below (even in storage). You can check the remaining charge on the battery by pressing the battery icon and activating the indicator lights.
Never allow the battery to fully discharge.
Store the battery at room temperature and away from moisture.
Remove the battery before filling up the sprayer.
Sprayer Not Priming
If you encounter a sprayer that is not automatically priming after storage or during the first use, this does not mean the pump is damaged or defective. It is likely the pump is just dry. There are easy ways to solve this issue.
Follow along with the video below or use the written instructions and select the method most convenient for you.
Step 1: With the battery removed, take off the tank lid and tank strainer.
Step 2: Reach into the bottom of the tank and gently twist off the inlet filter.
Step 3: Using a garden hose, direct fresh water into the exposed pump barb.
Step 4: Replace the inlet filter, tank strainer and tank lid.
Step 5: Test the sprayer by placing a battery in the holster and squeezing the spray gun trigger.
Step 1: With the battery removed, disconnect the spray gun from the hose. Make sure to leave the other end of the hose connected to the sprayer.
Step 2: Submerge the end of the hose in a bucket of clean water. You may bend the hose repeatedly to promote water to enter the hose.
Step 3: Re-attached the spray gun to the hose.
Step 4: Partially fill the sprayer tank with fresh water and place a battery into the holster. Activate the sprayer and press the trigger rapidly to test the sprayer.
