Oil lubrication

These units use high-performance lubrication oil. The lubrication oil will remain chemically and thermally stable, but should be replaced every 3,000
hours of operation to prolong the life of the unit. Use the oil level gauge to check the condition of the lubrication. Check lubrication when the unit hasstopped. If the oil appears low or discolored, change it with fresh oil regardless of the hours of operation. Occasionally, air bubbles may form in the oil
during operation but this is natural and not a quality concern.

※：Use the following lubricant for reﬁll.
Standard lubricant：Mobil SHC629 (VG150)
Use of diﬀerent oil can cause wearing or other problems.
