Overview

The STIHL SG 31 Manual Sprayer is a compact, portable hand-pressurized fluid sprayer designed for applying liquid fertilizers, pesticides, herbicides, weed control agents, and plant protection treatments around residential gardens, greenhouses, fruit trees, and small agricultural plots. Engineered for precision and mobility, the SG 31 provides homeowners and gardeners with an easy-to-use solution for localized liquid application.

Featuring a 5-liter translucent chemical tank with molded volume measuring scales, the SG 31 allows operators to check fluid levels and mixing ratios quickly. The sprayer operates via a smooth, manual piston pump built directly into the container lid, which pressurizes the vessel up to 3 bar (43.5 psi). It comes equipped with a safety pressure relief valve to prevent over-pressurization, a flexible delivery hose, an ergonomic trigger handle with a lockable spray switch, a brass hollow-cone nozzle for consistent atomization, and a padded shoulder strap for comfortable carrying during long spraying sessions.
