Watch out for HOT OIL. Immediately after operations, the oil will be very hot. Wait for the oil
temperature to go down before starting this maintenance operation.
1. Remove the oil level plug and check that the oil is near the
bottom edge of the plug hole.
2. If the oil level is low, remove the oil filler plug and add oil
until it reaches the bottom edge of the oil level plug hole.
3. After filling with new oil, check the oil level.
NOTICE
Always use genuine Komatsu Forklift gear oil (SAE 90). See
"LUBRICANT LIST" on page 4-2 for details.
Remark
On clutch-type lift trucks, the oil is used for both the differential
case and the transmission case. However, on the TORQFLOW
transmission lift truck, each case has its own special oil, so it is
necessary to check and change the oil in the TORQFLOW
transmission case in addition to checking and changing the oil in
the differential case in two separate operations.
