10. Bleed air from the hydraulic system:
The system controller has been designed to provide a purge option. With this
option applied, the generator will turn at a reduced speed to minimize wear to the
system’s hydraulic components while purging air from the system. The generator
is shipped from the factory with the purge option enabled. See Figure 13, below,
for instruction on manually enabling purge mode.
a. Turn off the generator’s main power breaker. Refer to Figure 11 for the breaker
location on the electrical enclosure, above.
b. Ensure hoses are securely attached to the hydraulic pump and not connected to
the generator.
c. Fill all hoses with fresh hydraulic fluid before connecting them to the generator
system. This will significantly reduce the required time to purge air from the
system.
d. Fill the Gen-set reservoir with fresh hydraulic fluid until the fluid in the sight gauge
is ½ to ¾ from the top. As hydraulic oil fills the system, maintain the level of fluid
in the reservoir.
e. Ensure the generator purge option is enabled.
f. Start the vehicle and engage the Power Take-Off (PTO). (Note: Pump may
cavitate briefly while air is purging, making noise.)
g. The automatic purging function will cancel after the hydraulic pressure has
stabilized, and the Command & Control Center will display all zeroes.
h. Check for hydraulic fluid leaks, all hose connections must be tight. Continue
monitoring the hydraulic fluid level, adding fluid as needed to keep the level
in the sight gauge.
Verify that the generator’s output frequency is 59-62 Hz for 60 Hz application, or 49-
52 Hz in 50hz application. If the frequency is not within that range, contact Smart

WARNING:
Never operate the system without the filler/breather cap installed. Contaminants may
enter the hydraulic fluid through the filler opening, causing premature wear on the
hydraulic components and void the system’s warranty.
Never apply a load to the generator while there is air trapped in the hydraulic fluid.
Damage to the system’s hydraulic components, as well as ruptured hoses, may result
and void the system’s warranty.
Always run the purge cycle after installation, after replacing the hydraulic fluid and
the filter, or after making any other repairs that may allow air into the hydraulic
system. Failure to do so will void the system’s warranty.
