7. Operate the machine as follows and then record the
pressure readings from the gauge and laptop
computer.
For arm regenerative solenoid valve (B), extend the
arm and lower the boom so bucket is in the ground
then actuate boom up and arm in functions in
combined operation.
For speed sensing solenoid valve (C), operate the
arm in function over relief to load the engine.
For propel speed change solenoid valve (D), drive
the machine at fast speed propel.
For power boost solenoid valve (E), push the power
boost button on right control lever.
8. Compare pressure reading from the gauge and laptop
computer. The pressure reading from the gauge must
be within the specified range of calculated pressure
reading on the laptop computer.
