Testing the Auxiliary Control Circuit - Hopper Lift Cylinder Internal
Leakage

Test Procedure
Hydraulic System: Testing the Hydraulic System
Perform a hopper lift cylinder internal leakage test if a raise/lower problem exists.
This test determines if the lift cylinder is damaged. Each hopper lift cylinder must
be tested individually.
Note: The raise/lower circuit operation can be affected by the hopper lift cylinder
binding, extra weight on the hopper, and/or binding of the lift components.
Ensure that these items are checked before continuing with the hopper lift
cylinder internal leakage test.
Note: When performing the lift cylinder internal leakage test, the hopper must
be attached to the lift arms.
1. Park the machine on a level surface and raise the hopper; refer to Operator's
Manual.
2. Switch of the PTO, shut off the engine, and set the parking brake.
3. Secure the hopper in raised position with hopper safety lock; refer to
Operator's Manual.
4. Clean the area around the hydraulic hoses end at the barrel end of the
hopper lift cylinder. Disconnect the hydraulic hoses from the hopper lift
cylinder barrel end fitting.
