German Knife by Turbo Air meat and bone saws feature a high quality stainless steel interior and frame. All of the internal material parts including the upper wheel, lower wheel, upper wheel hinge and the lower bearing housing are made with stainless steel. The automatic tension adjusting handle makes replacement of saw blades easy and maintains an even tension. The V-drive belt system motor produces less heat and runs at a lower temperature by using a high grade insulation and includes a cooling fan to reduce the possibility of overheating and an automatic over temperature shutdown sensor to prevent damage. Also features a sealed upper wheel assembly and the lower bearing housing allowing faster cleanup and protection when cutting wet products. 2 Year Limited Warranty.
