HYDRAULIC OIL SYSTEM
The hydraulic system consists of a hydraulic pump directly
coupled to the engine.
Hydraulic oil is filtered by a screen filter located in the tank
filler neck, a 10 micron inlet filter that connects to the
hydraulic tank and pump, and a 10 micron outlet filter that
connects from the cooler to the hydraulic tank. See
Figure 61.

Figure 61. Hydraulic Filter Locations
It is recommended that ISO 46 type hydraulic oil or equivalent
be used when adding or replacing the hydraulic oil.
DO NOT USE MULTI-VISCOSITY OIL. Cleanliness is a
very important part of proper hydraulic system operation.
Hydraulic oil is not only used to transfer power; it also
lubricates and cools the system components. Keeping
the hydraulic system clean can help reduce costly repairs.
The hydraulic oil level sight glass is located on the side of the
hydraulic tank This level should be checked daily. Oil must
be below the top and above the bottom of the sight glass.
DO NOT OVERFILL! Care should be taken to clean the filler
cap before adding oil to the system. If hydraulic oil has to be
added, the machine should be inspected for leaks.
CAUTION
DO NOT open hydraulic lines or loosen
hydraulic fittings while engine is running!
Hydraulic fluid under pressure can
penetrate the skin, blind, cause burns
or create other potentially dangerous
hazards follow all safety instructions as described
throughout this manual.
