9) Check the Hydraulic System
The Hydraulic Assembly is pre-assembled and tested for operation and leaks before shipping. The
pump is wired as shown on the Hydraulic Assembly drawing (pp. 53-56). Before operating the
system, check to see if the reservoir has adequate fluid. The fluid level of a folded system should
be approximately half full. Add only Dexron™ III ATF fluid. Do not overfill or fluid may leak out when
un-folded. Replace the cap in the fill port.
Read Operation Instructions (p. 19; Folding and Unfolding the System). To ensure all electrical and
hydraulic lines will not be damaged, use the switch at the rear of the truck to fold and unfold the
system twice. Cycling the SS180
®
M will purge excess air from hydraulic lines and confirm its
operational status.
Important:
Cycle the system using the cab switches to test controller operation.
