OPERATING ENGINE Warming Up Operation in Cold Weather In case the hydraulic oil temperature d isCAUTION: low, perform warm up operation. Operate the machine only after the loader front operating speed becomes normal. Operating the machine without warming up operation may cause the engine to be seizure or damaged and hydraulic system to be damaged. Be sure to perform warm up operation also to ensure safe operation such as protecting any accidents caused by unstable motion of hydraulic system. 1. Run the engine at low idle speed for more than 5 minutes. 2. Run the engine at medium speed for 5 minutes. IMPORTANT:
