The FLEX sanding machine is a highly ergonomic and lightweight tool designed for optimal ease of operation, providing comfortable working conditions. It features a well-balanced design between the motor and sanding head, utilizing FLEX technology for reliable power transmission and high flexibility via a flexible drive shaft. The motor's position near the head minimizes strain, making handling easier. The machine includes an electronic control system that maintains constant speed, offers soft-start functionality, overload protection, and allows for speed adjustments through an adjuster wheel. Dust is effectively extracted between the brush ring and sanding pad, promoting a dust-free working environment. It also offers connectivity with FLEX safety vacuum cleaners through the FLEX clip-system on the guide tube. The ergonomically shaped aluminum guide tube can accommodate an optional auxiliary handle for enhanced ease of use. The machine is dust-proof with a protected on/off switch and can be extended with an optional 500 mm accessory for working in high rooms. It is suitable for a wide range of applications, including sanding plasterboards, Styropor insulation slabs, and preparing surfaces for painting and polishing. The machine can handle large areas and rooms up to 3.40 meters in height when using the optional GM 340 application. Additionally, it is highly portable, featuring an innovative transport system that allows for effortless movement without the need for mounting. The gimbal-mounted sanding head provides excellent flexibility and precise adjustment for sanding walls and ceilings, making it a versatile and efficient tool for various finishing tasks.
