. OPERATION MACHINE OPERATIONS AND CONTROLS Check Oil Level in Hydraulic Tank, Add Oil WARNING before starting the work. When removing the oil filler cap, turn it slowly to release the internal pressure, then remove it. gauge (G). NOTICE REMARK The oil level will vary depending upon the oil temperature. Accordingly, use the following as the guide: Before operation: around L level (Oil temperature 10 to 30 ° C (50 to 86 ° F)) Normal operation: around H level (Oil temperature 50 to 80 ° C (122 to 176 ° F)) 3 - 45 The parts and oil are at high te mperature after the engine is stopped, and may cause burns. Wait for the temperature to go down 1.
If the work equipment is diagram on the right, sta speed, retract the arm a lower the boom, set the bu and stop the engine. not in the condition shown in the rt the engine, run the engine at low nd bucket cylinder rods fully, then cket teeth in contact with the ground, 2. Open the engine rear cov er and cooling cover. For details, see Section "COOLING COV ER (PAGE 3-29)". 3. Confirm that the oil level i s between the H and L marks of sight Do not add oil above the H line. cause the oil to spurt out.
This will damage the hydraulic circuit or If oil has been added above the H level, stop the upper structure so that the drain plug (P) under the hydraul ic tank will be between both tracks, and stop the engine and wait for the hydraulic oil to cool down, then drain the excess oil from drain plug (P). 4. If the oil level is below the L mark, open the dirt cover, move the cover on top of oil filler por (F). t (F), then add oil through oil filler port
