Genesis Rail Breaker GRB 30
24
HYDRAULIC START-UP
The Genesis Rail Breaker is designed to operate under full excavator pressure or up to 5500 PSI.
Due to these high pressures, it is important that air is bled from the attachment cylinder after in-
stallation. Failure to follow these procedures could result in cylinder seal damage and/or excavator
hydraulic system damage.
Start-up Procedure
3
Check the excavator hydraulic tank for proper fluid level.
3
Excavator oil should be warmed up before hooking up attachment lines in cold weather.
If oil is cold, air from the cylinder will be pushed into the oil tank, causing oil to foam. This
problem takes hours to correct, and it may cause pump cavitation.
3
Follow the OEM procedures for starting and warming the excavator hydraulic system. Do
not operate the attachment circuit during the warm-up period.
3
After the excavator has reached normal operating temperature, set the engine to idle
speed.
3
Attachment must be vertical. Do not allow the tank to run low - have someone watch the oil
gauge.
3
Slowly fill the bore end of the attachment cylinder to partially close the jaws.
3
Slowly fill the rod end of the attachment cylinder to open the jaws. Use partial strokes ex
-
tending and retracting, slowly working to full strokes.
3
Stop and check the excavator hydraulic fluid level again to be sure there is still sufficient
fluid. Service as required. Note: hydraulic fluid level should be checked with the attachment
jaws open (cylinder retracted).
3
Cycle the attachment jaws five or six strokes before increasing to full operating pressure.
Do not fully extend or retract attachment cylinder with the
first cycles.
