Using your Makita 18V LXT Sprayer is easy. First, make sure you have a fully - charged 18V LXT 5.0Ah Battery (sold separately) and insert it into the sprayer. Next, fill the 1.3 - gallon tank with the liquid you want to spray. You can choose between the mist or jet setting according to your needs. For targeted spraying, use the single - nozzle head, and for a wider area, switch to the two - nozzle heads. You can adjust the pressure between 19 and 38 PSI with the adjustable nozzles. If you need to spray for a long time, use the lock - on feature on the handle. The telescoping spray wand can be adjusted to the right length for better reach. After use, make sure to empty the tank and clean the sprayer thoroughly. Store the wand on the sprayer for easy transport. Keep the sprayer in a dry place to protect it from dust and water. And always use genuine Makita batteries and chargers to ensure good performance and a long life for your sprayer. Also, note that it comes with a 3 - year limited warranty.
