IMPORTANT
Cold weather operation requires that the operator fully warm up the hydraulic oil before
beginning machine operation. Follow all warm up instructions listed in the Operating Instruction
section of this manual. Make sure to cycle oil through all of the components, including all
cylinders, both travel motors and the swing motor. Cold hydraulic oil in the lines and
components needs to be warmed before beginning full operation. If this is not done, damage to
the cylinders or hydraulic motors can occur.
