MAINTENANCE PROCEDURE
CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL
The parts and oil are at high temperature after the engine is stopped, and may cause serious burns.
Wait for the temperature to go down before starting the operation.
If there is still pressure remaining inside the case, the oil or plug may fly out.
Loosen the plug slowly to release the pressure.
Prepare a hexagonal 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 level plug (G) with a hexagon wrench (Width
across flats: 8mm). Oil level should be near the bottom of
the plug hole.
4.
If the oil level is still too low, add engine oil through the
hole in plug (G) until the oil overflows.
5.
After checking, install plug (G).
REPLACE HYDRAULIC OIL FILTER ELEMENT
The parts and oil are at high temperature after the engine is stopped, and may cause serious burns.
Wait for the temperature to go down before cleaning the hydraulic tank strainer.
When the oil filler cap is removed, oil may spurt out, so turn the cap slowly to release the internal
pressure,then remove it carefully.
NOTICE
If the machine is equipped with a hydraulic breaker, the hydraulic oil will deteriorate much faster than dur-
ing normal bucket operations. For details, see "MAINTENANCE INTERVAL FOR HYDRAULIC BREAKER
(PAGE 4-19)" when carrying out maintenance.
Prepare a filter wrench for hydraulic filter cartridge.
1.
Tip the operator's seat and remove the toolbox from under the seat. For details, see "TIPPING OPERA-
TOR'S SEAT (PAGE 3-20)".
2.
Remove cover at the left side of the machine.
