Cold temperatures have a significant impact on pressure
readings. JLG Industries Inc. recommends operating the
machine until hydraulic systems have warmed to normal
operating temperatures prior to checking pressures. It is
also recommended using a calibrated gauge. Pressure
readings are accepted if within +/-5% of specified pres-
sures.
