Transmission (gear) oil level (Figure 12)
Check the level with the machine on a flat surface. Oil level

Use only SAE 90 or API GL-5. Oil capacity : 1.00L

Each 100 hours or Every year whichever comes first.
HST oil level (Figure 14)
Check HST oil level regularly with the machine on a flat surface. Be sure correct oil level is
maintained. Oil level should reach the upper level "FULL". If needed, add the oil “VG46” or “SAE
10W30”. Refill the same type of oil. Never mix different type of oil.
Oil capacity: 0.50L(RM882/RM952), 5.0L(RM982F).
Check for oil leak.
Rear HST oil replacement (Figure 13,Figure 14)
HST oil is clean when the unit is delivered. But when the unit is used for a long time, the inside of HST
unit will be dirty because there are some sludge and the oil is degraded. And dirty oil might disturb the
smooth working.
Replace HST oil frequently for your safety and smooth working.
Also replace oil filter when HST oil is replaced.
Drain the used oil
1. Place the suitable container below the HST unit to catch the oil, then remove the oil drain plug (1
Figure 13).
2. Allow the used oil to drain completely, then reinstall the oil drain plug, and tighten the oil drain plug
securely.
3. With the HST unit on a flat surface, refill to the upper limit mark with the recommended oil. (Refill
same oil if possible.)
When oil is added, please pay high attention not to mix dust with oil. Tighten the cap securely to
prevent leakage.
