Look at the gauges frequently during operation.Also, to speed hydraulic oil warm-up, hold the bucket control in the CLOSE position for short periods, not more than 10 seconds.This will allow the oil to reach relief pressure, which causes it to warm more rapidly.Cycle all controls to allow warm oil to circulate through all cylinders and lines.When idling the engine for warm-up, observe the following recommendations:* In temperatures above 0°C (32°F), warm-up requires approximately 15 minutes.* In temperatures below 0°C (32°F), warm-up requires approximately 30 minutes or more.* In temperatures below -18°C (0°F) or if hydraulic functions are sluggish, more time may be required.
