4.3.2 Prevent corrosion of extended hydraulic cylinders

Store the machine with the cylinders in the retracted position. If the machine is stored with cylinders in the
extended position, periodically cycle the cylinder. If a cylinder must be stored in the extended position
without being cycled, the following corrosion prevention must be done.
Procedure
1. Use a dry cloth or cloth with solvent to clean any dirt from the cylinder shaft.
2. Prepare a mixture of 60 percent oil based rust inhibitor and 40 percent Kerosene.
3. Use a cloth to apply a thin layer of this mixture to the surface of the chrome plated shaft. Number
one fuel oil can be replaced with Kerosene. A good grade purpose made product can be used for
this procedure.
