Hydraulic Power Supply
Electrical Operation
1. The Hydraulic Power Supply Electrical system is also
used to power the hydraulic system.
IMPORTANT
1. Check the hydraulic oil level before starting the
hydraulic power supply electrical package.
(Check oil level while semitrailer is not tilted as
tilting will change the oil level in the tank.)
2. Flip battery shutoff switch to ON position.
If the hydraulic fluid level is low during operation,
the semitrailer may not operate correctly,
resulting in damage to the semitrailer.
