Lubricate all of the joints for each pin assembly.Note: Use the following steps in order to perform the correct break-in procedure for the work tool.
Raise the work tool to approximately 1/3 maximum height.
Lower the work tool to the ground and apply slight downward pressure. The downward pressure reverses the direction on the load on the pin.
Repeat the procedure for 20 to 30 cycles. Then, gradually increase the height of the work tool at each cycle until the maximum height is reached.
Lubricate all the joints on each pin assembly.End By: Separate the steering frame lock. Refer to Disassembly and Assembly, "Steering Frame Lock - Separate and Connect".
