[4] CHECKING/REFILLING OIL LEVEL IN SLEWING REDUCTION GEAR CASE Securely tighten the filler plug after refilling with the oil. If the filler plug falls during the operation, the hot oil spouts out of the pan, causing burns.
CAUTION • See “Maintenance 5.1 Use of Lubricating Oil According to Temperature” for which oil to be used. • Use seal tape, etc. at the thread of the filler plug to stop the oil leak and securely tighten the plug after refilling with the oil. 1. Stop the machine on a level surface. 2. See “Operation 1.6 Machinery Cover” to remove the machinery cover. 3. Remove 2 mounting bolts (2) and then remove the slewing gear cover (1). 4. Remove the oil filler plug (F) in the slewing reduction gear case and put your finger into the hole to check that the oil is sufficient to almost reach the plug hole mouth. 5. If the oil level is low, refill with the gear oil from the plug hole of the filler plug (F).
NOTES Oil shall be refilled until it almost reaches the plug hole mouth.
6. Put in the filler plug (F) and secure it after oil checking/refilling. 7. Install the slewing gear cover (1) to the original position and tighten the 2 mounting bolts securely. 8. Install the machinery cover. For detail, see “Operation 1.6 Machinery Cover”.
