Parts and oil are at high temperature immediately after the engine is stopped and may cause serious burns. Wait for the oil
temperature to go down before performing this operation.
Refill capacity: 38 liters (10.04 US gal)
Prepare a socket wrench and filter wrench.
1. Remove the cover (1) on the bottom of the machine and set a
container to catch the drained oil directly under the drain plug.
2. Loosen drain plug (P) (with a slit) slowly to avoid getting oil on
yourself, and drain the oil.
3. Check the drained oil, and if there are excessive metal
particles or foreign material, please contact your Komatsu
distributor.
4. Install drain plug (P).
5. Open the engine side cover on the left side of the chassis.
6. Using the filter wrench, turn engine oil filter cartridge (2) to the
left and remove it.
7. Clean the filter holder, fill the new filter cartridge with clean
engine oil, coat the thread and packing surface of the new filter
cartridge with clean engine oil (or coat it thinly with grease),
then install it to the filter holder.
8. When installing the filter cartridge, bring the packing surface
into contact with the filter holder, then tighten a further 3/4 to 1
turn.
9. After replacing the filter cartridge, add engine oil through oil
filler port (F) so that the oil level is between the H and L marks
on dipstick (G).
10. Run the engine at idling for a short time, then stop the engine,
and check that the oil level is between the H and L marks on the
dipstick. For details, see "CHECK OIL LEVEL IN ENGINE OIL
