When hydraulic oil is less than 25℃, it is needed to preheat the machine before any work; otherwise
machine may not respond or react very quickly, leading to severe accident.
Therefore it is needed to preheat machine if it is cold:
①
.
Adjust the manual accelerator to have engine run at medium speed, and then slowly move bucket forth and
back for 5min.
Caution: do not operate other actuators than the bucket.
②. Adjust the manual accelerator to have engine run at high speed, and then move the boom, the arm and the
bucket for 5-10min.
Caution: operations are merely limited on boom, arm and bucket, instead of any slewing or traveling.
③. Each complete action of excavator should be carried out for a few times, completing the preheating and ready
to work.
