d. Keep the hose from twisting. Twisted hoses can
cause couplers to loosen as the hose flexes
during operation resulting in oil leaks.
e. Kinked or twisted hoses can restrict the oil flow
causing the system to malfunction and the oil to
overheat and also lead to hose failure.
5.10 HYDRAULIC OIL AND FILTER _______________________________________________
Refer to Section 7.3 for specific maintenance intervals.
Drain and replace the hydraulic oil after a major
component failure, or if you notice the presence of water
or foam in the oil, or a rancid odor (indicating excessive
heat).
Always replace the hydraulic filter when changing oil.
To change hydraulic oil:
1. Clean the area around the oil cap to prevent
impurities from entering and contaminating the
system.
2. Remove drain plug from bottom of main tank.
3. After oil has drained install drain plug and fill with
Jacobsen hydraulic oil.
4. Purge air from system.
a. Operate all aerator functions for about 5 minutes
to purge air out of the system and stabilize the oil
level.
b. Once the level has stabilized and the air is
purged, fill tank to full mark on gauge
The hydraulic system is protected by one 10 micron filter.
The filter is located under the frame near the hydraulic oil
tank.
