Isn’t it what all of us want on a building project? The good feeling of knowing that everything works with maximum efficiency and reliability. Especially on construction sites, each cog in the system must interact perfectly with the others to ensure a smooth building process. This requires reliable machinery, from large excavators to compact handheld machines – and this reliability must extend from the first step in the construction process all the way to the final approval. For renovations involving flooring, floor saws and concrete saws are usually the first step in the process.

Lissmac is one of the innovation and market leaders in this sector. The Swabian company, headquartered in Bad Wurzach, Germany, has been producing masonry saws and floor saws for nearly 45 years. Power, reliability, and smooth operation are crucial factors in these machines. It is no different with the Lissmac Multicut 905 floor saw, which is driven by a Hatz 4H50TICD four-cylinder engine. No wonder, says Daniel Keller, Executive Director of Lissmac Maschinenbau GmbH: “The Hatz engine and our Multicut machine are a great combination. Floor saws require an enormous amount of power in a small space, and it must be available very quickly. The 4H50TICD engine from Hatz is perfect for this.”

On construction sites – where the schedule is tight – the next tradespeople are usually already prepared when the floor is being cut. There can be no delays. The floor saw has to work right from the beginning. “Delays on construction sites are always frustrating, for the building contractor but also for the subcontractors who are affected. It is therefore very important that the machines just work. Machinery failures are unforgivable, especially with compact machines. Reliability is the most important thing for the construction company,” that much Daniel Keller is sure of. “That is another reason why we rely on Hatz drives.”

Lissmac and Hatz have worked together for a long time. For its smaller compact machines, the machinery manufacturer has relied on the air-cooled Hatz B, D and G-series engines since the 1990s. The larger, self-driving masonry saws were redesigned by Lissmac in 2017. During the planning stage, Lissmac was already on the lookout for the ideal drive – and found the 4H50TICD for the Multicut 905. It gives the machine the necessary smooth running behavior, as Daniel Keller explains: “As the heart of the machine, the Hatz engine provides almost 75 horsepower. With that power, we can cut directly into the concrete at maximum rotational speed. The machine runs very smoothly, which protects the blade and mechanical system of the floor saw.”

Thanks to its compact design and low weight, the operator can move the Multicut 905 especially easily and ergonomically. This, in turn, protects workers from occupational injuries and long-term mobility issues. Lissmac’s optimal chassis design as well as the compact and lightweight engine all make positive contributions. Daniel Keller says in conclusion, “For our premium machines, we need premium partners that support us with the technology and functionality we need on our mission to provide innovation and performance. Hatz does that like no other drive manufacturer.”
