Test Procedure (continued)
ProLine H800
19241SL Rev A
When capping the hopper tilt cylinder fitting and hydraulic hose end,
use a steel cap and plug to ensure that there is no fluid leakage. The
plastic plugs cannot hold the hydraulic pressure that is developed
during this test procedure.
5. Install a steel cap on the open hopper tilt cylinder fitting to seal the tilt
cylinder. Also, install a steel plug in the open end of the disconnected hose to
prevent leakage or contamination.
6. Allow the hopper weight onto the hopper tilt cylinder.
7. The capped hopper tilt cylinder should be able to support the hopper long
enough for the machine to tilt and clean the hopper.
8. If the hopper tilt cylinder allows the hopper to lower too quickly, replace the
hopper tilt cylinder; refer to
9. Once the hopper tilt cylinder condition is determined, tilt the hopper slightly
which removes the load from the tilt cylinder.
10. Secure the hopper in tilt position.
11. Remove the cap from the cylinder fitting and the plug from the hydraulic hose.
12. Connect the hydraulic hose to the tilt cylinder fitting.
13. Start the engine and operate the hopper tilt cylinders through several tilt and
lower cycles. Shut off the engine and check for any leakage.
14. If necessary, repeat the steps
15. Check and fill the hydraulic tank with the correct quantity of new hydraulic
fluid before returning the machine to service.
