HYDRAULIC FILTRATION
2. Remove the drain plug and allow the oil to drain.
3. Dispose of the used oil in an enviromentally safe manner.
4. Remove and inspect the Reservoir Suction Strainers:
a. Disconnect the suction lines (a.k.a. supply line) from the shutoff valve.
b. Remove all other fittings to permit access to the suction strainers.
c. Remove the suction strainers by turning the large hexagonal flange counterclockwise
until it is free from the reservoir.
d. Thoroughly inspect the suction strainers for foreign matter and/or damage.
e. If the suction strainers are undamaged clean them with a degreasing solution and a brush.
If there is any damage to the suction strainers replace them with a new strainer. See below for
suction strainer replacement information.
f. Check for and anylize any debris on the bottom of the reservoir. This is done by reaching through the suction
strainer ports and feeling aroound on the bottom of the reservoir. If excess metal shavings are found it
could be an indicator of pump or motor damage.
g. With inspection complete, reinstall the suction strainers, fittings and suction line. Use appropriate pipe
thread sealant on all threaded connections.
5. Reinstall the drain plug. Use an appropriate pipe thread sealant on the threads of the drain plug.
6. Remove and inspect the breather/filler cap from the reservoir. Follow the breather/filler cap service and
maintenance instructions following this section.
7. Add new filtered hydraulic oil of appropriate specification to the hydraulic reservoir. Add the oil slowly and carefully
to avoid spillage. Continue filling the reservoir until the oil level sight glass indicates that the tank is full.
8. Ensure that all of the reservoir shutoff valves are completely open.
9. Following the startup proceedures described in this manual, start the truck engine and allow the pumps to operate
in neutral for 5 minutes to allow the system to fill with oil and purge any air in the system.
10. After the 5 minutes of running in neutral, engage the pumps and check for hydraulic leaks and verify proper operation
of the machine.
11. Re-check the oil level in the hydraulic reservoir and add oil as needed to maintain the proper level indicated by the
oil level gauge.
