Bosch GSA 18 V-LI Black, Blue

The Bosch GSA 18 V-LI is a cordless reciprocating saw designed for versatile cutting tasks. It offers a 28 mm stroke length and a stroke rate of up to 2,700 strokes per minute, powered by a 18 V lithium-ion battery with 5.0 Ah capacity. At approximately 3.4 kg, the saw combines mobility with sufficient power for demolition, renovation and installation work. Integrated battery protection prevents deep discharge, overheating and overload to enhance tool and battery reliability.

Advantages

Innovative CoolPack battery technology improves heat dissipation and can extend battery lifetime by up to 100% compared with lithium-ion cells without CoolPack. Bosch Electronic Cell Protection (ECP) protects the battery from overload, overheating and deep discharge. Two-stage speed setting enables adjustment of cutting speed for different materials while an ergonomically shaped handle with a softgrip comfort zone provides a secure hold and reduces user fatigue.

Suitable for

• Demolition and dismantling work in construction and renovation
• Cutting through wood, metal pipes and profiles with appropriate blades
• Installation tasks requiring precise or fast reciprocating cuts

How to use

Install a compatible reciprocating saw blade according to the blade holder instructions. Select the required speed setting depending on the material: use the lower stage for controlled cuts and harder materials, the higher stage for faster progress in softer materials. Maintain a stable grip using the softgrip handle, start the saw before contacting the workpiece and allow the blade to reach full speed. Apply steady, even pressure and avoid forcing the blade. After use, switch off the tool, remove the battery for storage or charging, and inspect the blade for wear.

Recommendations

Use blades matched to the material and application, check battery charge level before starting demanding tasks, and follow safety instructions in the user manual. For prolonged cutting sessions, allow batteries to cool between charges to preserve CoolPack benefits.
