IMPORTANT
Cold weather operation requires that the operator fully

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

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.
