Performance of
hydraulic pump
a As far as possible, bring pump discharge pressure P1 and P2 as close as possible to the average pres-
sure when measuring.
a When measuring with the pump mounted on the machine, if it is impossible to set the engine speed to
the specified speed with the fuel control dial, take the pump discharge amount and the engine speed at
the point of measurement, and use them as a base for calculating the pump discharge amount at the
specified speed.
