7.) FINAL CHECK LIST

 

1.) With all jacks fully retracted, check the oil level. The oil 
level should be within 1 inch of the top of the reservoir.

2.) Check all hose connections for leaks and check hose 

routings for heat or rubbing issues. Make sure all hoses 

are fastened or supported properly.

3.) Check all wiring connections for tightness and make 
sure all exposed connections are protected against 

moisture and corrosion. Check harness routings for heat 
or rubbing issues Make sure harnesses and wires are 

fastened or supported properly.

4.) Check all mounting bolts and brackets for the jacks, 

power unit and/or control box are tight. 

5.) Check that all indicator lights including the master 
warning light and buzzer (if so equipped) are functioning 

properly.

6.) Run the system with the owner to explain the correct 
operation and function of the leveling system in both the 
manual and automatic mode.

7.) Make sure the owner receives the owner’s manual. 

Review the manual, especially cautions, with the owner.
