    HYDRAULICS INTRODUCTION The hydraulic system on the model 6200E consists of the electro/hydraulic pump, reservoir, hoses, and hopper lift cylinder. 6200E 330415 (6- -99)

  • Page 208: Hydraulic Fluid Reservoir

    The quality and condition of the hydraulic fluid play a very important role in how well the machine operates. Tennant’s hydraulic fluid is specially selected to meet the needs of Tennant machines. Tennant’s hydraulic fluids provide a longer life for the hydraulic components. There are two fluids...
