Check Operation of All Controls

2. Follow cold weather hydraulic system warm-up
procedures.
3. Note any slow operations or unusual movements.
Determine the cause and repair fault before operating.
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.
