RedMax 4GL— Product Specification

    • Professional 4‑gallon backpack sprayer for herbicides, pesticides, fertilizers, and cleaning solutions on residential and commercial properties.

    • Internal no‑leak pump design is aimed at pro landscapers who need durability and safety when carrying chemicals on their back.

    • Manual piston/diaphragm backpack capable of up to 150 psi, with a 25 psi pressure regulator that delivers constant pressure for consistent spray patterns when applying lawn chemicals.

    • 4‑gallon backpack tank with internal pump, designed to prevent leaks against the operator’s back.

    • Frame includes deluxe comfort harness with padded shoulder straps for extended wear.

    • Pump handle can be stored vertically or horizontally and is easily accessed for pumping and service.

    • Pro shut‑off handle with comfortable grip, 50 in reinforced PVC hose with strain‑relief nut to prevent kinking, and 25 in stainless steel wand with poly liner for chemical resistance.

    • Easy‑access pump design lets you change seals in minutes without tools.

    • Included 3‑nozzle kit: brass adjustable nozzle plus two high‑volume fan nozzles (commonly red and yellow poly) with cap nut and Viton gasket. Compatible with additional nozzles and accessories used across RedMax 4‑gallon sprayer line (e.g., disinfectant/fine mist nozzles), sold separately.

    • Internal no‑leak pump reduces risk of chemical exposure on the user’s back compared with external‑pump designs.

    • Pressure relief and high‑quality seals support safe depressurizing before opening the tank; always follow chemical label PPE requirements.

    • After each use: depressurize, empty, and rinse tank; run clean water through hose, wand, and nozzles; store depressurized.

    • Periodically: inspect and clean in‑line filter(s) and nozzle screens, check/replace seals and hose as needed.

    • Pump seals can be replaced quickly via the easy‑access pump housing.

    • Liquid capacity 4 gallons (15.1 L).

    • Hose length about 50 in

    • Wand length 25 in giving good reach for shrubs, beds, and small trees.

    • Refer to the RedMax owner's manual and official RedMax warranty documentation for full coverage terms, conditions, exclusions, and claim procedures applicable to this model

    • “4GL Manual Sprayer” aligns with the manual 4 Gallon Backpack Sprayer spec set; the 4 Gallon Battery Backpack Sprayer uses the same tank, wand, hose, and nozzle kit, but replaces pumping with an 18 V battery-powered internal pump (no manual pumping).
