hydraulic oil. (Check oil level while semitrailer is
not tilted as tilting will change the oil level in the
tank.)

3. If the engine does not crank, check the following
on the battery: charge, fluid, terminals, and
cables. take corrective actions as needed.
If the hydraulic fluid level is low during operation,
the semitrailer may not operate correctly,
resulting in damage to the semitrailer.

hydraulic controls on the driver's side of the
semitrailer. Use the key to start and stop the
Hydraulic Power Supply Engine (See Figure 3-3.)
