Check Oil Level In Final Drive Case, Add Oil; Clean And Inspect Radiator Fins And Oil Cooler Fins - Komatsu PC18MR-3 Operation & Maintenance Manual

MAINTENANCE PROCEDURE

CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL

The parts and oil are at high temperature immediately after the engine is stopped, and may cause serious burns. Wait for the
temperature to go down before starting the operation.
If there is internal pressure inside the case, the oil or plug may fly out.
Loosen the plug slowly to release the pressure.
Prepare a container to catch drained oil.
Prepare a hexagon wrench.
1. Set so that drain plug (P) is at the bottom.
2. Set a container under plug (G) to catch the oil.
3. Remove plug (G) with a hexagonal wrench. Oil level shouldbe
near the bottom of the plug hole (G).
4. If the oil level is low, add oil through the hole in plug (G) until the
oil overflows.
5. After checking, install plug (G).

CLEAN AND INSPECT RADIATOR FINS AND OIL COOLER FINS

If compressed air, high-pressure water, or steam hits your body directly or dirt is sent flying by the compressed air, high-pressure
water, or steam, there is danger of personal injury. Always wear protective glasses, dust mask, and other protective equipment.
NOTICE
When use the compressed air, keep a distance from air nozzle, to prevents damage to the fins.
To prevent damage to the fins, apply compressed air from and appropriate distance. Damaged fins may cause water leakage or
overheating. In a dusty site, check the fins daily, irrespective of the maintenance interval.
1. Open the cooling cover. For details, see "COOLING COVER (PAGE 3-21)".
2. Use compressed air, steam, or water to blow off the mud, dirt,
and leaves clogging radiator fins and oil cooler fins (1).
Steam or water may be used instead of compressed air.
However, when carrying out powerful steam cleaning
(high-pressure machine wash) of the heat exchange
equipment (radiator, oil cooler), maintain sufficient distance
from the machine when carrying out the operation. If steam
cleaning (high-pressure machine wash) is carried out at close
range, there is danger that the internal fins of the heat
exchange equipment may be deformed, and this will cause
early clogging and breakage.
