# §112.50-3. Hydraulic starting.


A hydraulic starting system must meet the following:

- (a) The hydraulic starting system must be a self-contained system that provides the cranking torque and engine starting RPM recommended by the engine manufacturer. The hydraulic starting system must be capable of six consecutive starts, unless a second, separate source of starting energy capable of three consecutive starts is provided. A second, separate source of starting energy may provide three of the required six starts. If a second source is provided, the hydraulic system need only provide three consecutive starts.
- (b) The stored hydraulic pressure must be automatically maintained within the predetermined pressure limits.
- (c) The means of automatically maintaining the hydraulic system within the predetermined pressure limits must be electrically energized from the final emergency bus.
- (d) There must be a means to manually recharge the hydraulic system.
- (e) Charging of the hydraulic starting system must not cause insufficient hydraulic pressure for engine starting.
