HYDRAULIC FILTRATION
The hydraulic oil used in the hydraulic system on your 6100 series mixer was selected for its heavy duty operating
properties. This minimizes frequent hydraulic oil changes and extends the life of the hydraulic systems components.
It is recommended to change the hydraulic oil every 1000 hours of regular use or when oil properties degrade. If
the fluid becomes black it is a sign that the fluid is overheating. Also, if the fluid appears to be milky, this is a sign of
water contamination.
If in doubt as to the condition of your hydraulic oil, contact your authorized SAC Dealer or Distributor or your local
hydraulic service center. A sample of the hydraulic oil can be tested with the correct testing equipment. Good condition
hydraulic oil must meet the following minimum requirements.
Your mixer is equipped with an integral charge pump filter. It is critical that this filter is changed on a regular
basis to keep the system running normal. The charge filter (1 per unit, located on the hydrostatic pump next to
the auxiliary pump) must be changed within 20 hours of initial startup. The filter must be changed again at 100
hours of use. After the first two initial filter changes within 100 hours of startup, the filter changes must occur
every 250 hours therafter.
The auxiliary circuit filter (located near the cooling fan) must be changed after 50 hours of initial startup and
every 500 hours thereafter.
Changing Hydraulic Oil and Reservoir Maintenance
The following steps should be followed to change the hydraulic fluid and clean the reservoir:
1. Position catch containers under the reservoir below the drain plug. Make sure the ball valves located on the tank
are in the open position. The volume of the hydraulic reservoir is large; make sure the selected containers are
suitable to hold the complete volume of fluid.
