This Oval Hand - held Vacuum Cup is an excellent tool for handling glass, stone, and steel pipes. Crafted from aluminium, it features an ergonomic handle along with an integrated vacuum gauge and a pump. Ideal for non - porous materials with smooth and curved surfaces, this vacuum cup creates a vacuum by repeatedly pulling the hand pump. You can continuously monitor the vacuum via the pressure gauge and add more pumping whenever needed. It has rust - resistant parts that can withstand wet conditions in stone working and comes with a protective carrying case. It only takes three pumps to achieve full vacuum. Here are the specifications: In metric units, the oval pad has a length of 380mm and a width of 80mm, with a working load limit of 90kg and a net weight of 1.3kg. In imperial units, the length is 15 inches, width is 3.1 inches, working load limit is 198 lbs, and net weight is 2.9 lbs.



Using this Oval Hand - held Vacuum Cup is easy. First, make sure the surface of the material (like glass, stone, or steel pipes) is smooth and non - porous. Place the cup on the surface. Then, start pulling the hand pump repeatedly. It only takes three pumps to create a full vacuum. You can check the vacuum level on the pressure gauge. If you notice the vacuum is dropping, just give the pump a few more pulls. When it comes to safety, always check the working load limit. Don't try to lift objects that are heavier than 90kg (198 lbs). Also, avoid using it on porous or rough surfaces as it won't work effectively. For maintenance, keep it clean after each use. Wipe it with a dry cloth. The rust - resistant parts are durable, but if it gets wet during stone working, dry it thoroughly. Store it in the protective carrying case when not in use to prevent damage.
