SECTION 5 - HYDRAULIC

The S20P hydraulic system does not require any special work on a new machine before its start up. The hydraulic tank is

filled with Texaco Rando HD46 hydraulic oil and all machine

functions have been tested at the factory to ensure proper
operation upon initial start up.

The oil level in the hydraulic power pack should be main-
tained, and if necessary, topped up. The usable volume of
the oil reservoir is 0.66 US gallons (2.5 litres).
