Milwaukee 15L Chemical Sprayer, 18V Backpack Sprayer for Chemicals

Key specs: 15-liter tank capacity, 18-volt battery (bare tool, battery not included), adjustable pressure, and a flow rate of 0.5–1.0 gallons per minute. The backpack design with padded straps supports comfortable all-day use.

Yes, it’s sold as a bare tool, so you’ll need to supply your own 18V Milwaukee battery and charger to power it.

Steps: 1) Charge a compatible 18V Milwaukee battery. 2) Fill the 15L tank with your chosen chemical solution to the recommended level. 3) Attach the battery, prime the pump if required, and fit the adjustable spray nozzle. 4) Set the desired pressure (within the 0.5–1.0 GPM range) and begin spraying. 5) After use, rinse and clean the system to prevent chemical residue buildup.

You can spray herbicides, pesticides, and other compatible liquid chemicals. Always follow the chemical label instructions, use appropriate PPE, avoid mixing incompatible chemicals, and never spray near people, pets, or water sources unless the label allows it.

Rinse the tank and lines with clean water, flush the system, clean the nozzle and intake filter, and dry before storage. Regular inspection of seals, hoses, and fittings helps prevent leaks and ensures consistent performance.

Runtime depends on the battery capacity you install and the selected flow rate. With a higher-capacity 18V Milwaukee battery, you can spray longer between charges, but exact duration will vary with spray tasks and settings.

Wear the sprayer as a backpack, adjust padded shoulder straps and the chest/waist strap for a snug fit, and balance the load to reduce fatigue. The ergonomic design is intended to make extended use more comfortable.

Always wear appropriate PPE (gloves, goggles, long sleeves), avoid drift to non-target plants or people, store chemicals securely, follow local regulations on application, and keep the unit away from children and pets when not in use.

Yes, consider extra nozzles tailored for misting or direct spray, replacement filters, and additional packing for chemical compatibility. Accessories should be sourced from Fepy to ensure compatibility with the Milwaukee M18BPFP-CST system.

For large areas or frequent spraying, the 15L tank reduces refills and the 0.5–1.0 GPM flow lets you control coverage. For smaller areas or precision spots, you might opt for a smaller capacity model with a steadier, finer spray. Review your area size, chemical type, and spray pattern needs to decide if this model meets your requirements.
