Lubricant Viscosities
General
• Follow tractor manufacture's maintenance and lubrication instructions for tractor service as required.
• Follow tractor and/or winch manufacture’s lubrication instructions for the pipelayer hydraulic system.
• To prevent corrosion damage to the winch interiors, if not used regularly, cycle the winches up and down several times
at least once every two weeks.
Selecting the Viscosity
The proper oil viscosity grade is determined by the minimum outside temperature. This is the temperature when the machine
is started and when the machine is operated. In order to determine the proper oil viscosity grade, refer to the "Min" column
in the table. This information reflects the coldest ambient temperature condition for starting a cold machine and for
operating a cold machine. Refer to the "Max" column in the table in order to select the oil viscosity grade for operating the
machine at the highest temperature that is anticipated. Use the highest oil viscosity that is allowed for the ambient
temperature when you start the machine.
Machines that are operated continuously should use oils that have the higher oil viscosity in the final drives and in the
differentials. The oils that have the higher oil viscosity will maintain the highest possible oil film thickness. Consult your
dealer if additional information is needed.
