Note : Machines are shipped from factory with ISO VG46 for hydraulic oil and with SAE 10W-30 for engine oil.
Note : USE OF BIO-DEGRADABLE OILS When you use Bio-degradable Oil (BIO OIL), refer to the following information. 1. There are two types of BIO OIL available; vegetable-based and synthetic-based. You are recommended to use the synthetic-based type, because the vegetable-based oil has a maximum usage temperature of 80˚C {176˚F}. Because of this, the degradation of vegetable-based oil occurs more rapidly, and causes reduced service life. 2. Do not mix either type of BIO OIL with the original factory-filled mineral oil, in the case that you do use BIO OIL, it is required to flush the hydraulic system that was filled with BIO OIL three times. 3. If you use BIO OIL, slewing and propel parking brake performance will be reduced, because of the lower friction factor of BIO OIL compared to that of mineral oil. 4. For further information about recommended Bio-degradable oil, please contact our distributor.

SK75UR-3E CAB INTERFERENCE PREVENTION SYSTEM (SK75UR-3E) Note : The contents in para. 1), 2) and 3), are in common to the concerned sections (Boom up, Arm in, Off-set left). 1) The potentiometer output voltages for boom, arm and off-set operations are input to mechatro controller. 2) The mechatro controller detects that any of boom, arm and off-set are entered in interference area with each potentiometer output voltage. 3) And simultaneously detects the ATT position and speed, and outputs command to proportional valves for boom up, arm in and off-set left to gradually stop the movement in the interference area, according to respective command. (1) Boom up 4) The boom up proportional valve controls the proportional valve secondary pressure according to command output by mechatro controller; consequently the conflux valve of boom main spool and boom on the control valve starts returning. 5) Simultaneously changes value of command to P2 cut proportional valve according to the controlled boom up pilot secondary pressure. 6) And P2 cut proportional valve controls the proportional valve secondary pressure to the pressure corresponding to the command output by mechatro controller. 7) The boom main spool and boom conflux valve, and P2 cut proportional valve are switched by mechatro pressure command, consequently cylinder supply flow rate is gradually reduced during boom up operation in the range of boom up interference area, and ATT smoothly stops. (2) Arm in 4) The arm in proportional valve controls proportional valve secondary pressure according to command output by mechatro controller, consequently the arm main spool on the control valve starts returning. 5) Simultaneously changes values of command to P1 cut valve & Arm conflux valve and P2 cut proportional valve according to the controlled arm in pilot secondary pressure. 6) And P1 cut valve & Arm conflux valve and P2 cut proportional valve control the proportional valve secondary pressure to the pressure corresponding to the command output by mechatro controller. 7) The arm main spool and P1 cut & Am conflux valve and P2 cut proportional valve are switched by mechatro pressure command, consequently cylinder supply flow rate is gradually reduced during arm in operation in the range of arm in interference area, and ATT smoothly stops. (3) Off-set left 4) The off-set left proportional valve controls proportional valve secondary pressure according to command output by mechatro controller; consequently the off-set main spool on the control valve starts returning. 5) The off-set main spool is switched by mechatro pressure command, consequently cylinder supply flow rate is gradually reduced during off-set left operation in the range of off-set left interference area, and ATT smoothly stops.

SK130UR-1E CAB INTERFERENCE PREVENTION SYSTEM (SK130UR-1E) Note : The contents in para. 1), 2) and 3), are in common to the concerned sections (Boom up, Arm in, Off-set left). 1) The potentiometer output voltages for boom, arm and off-set operations are input to mechatro controller. 2) The mechatro controller detects that any of boom, arm and off-set are entered in interference area with each potentiometer output voltage. 3) And simultaneously detects the ATT position and speed, and outputs command to proportional valves for boom up, arm in and off-set left to gradually stop the movement in the interference area, according to respective command. (1) Boom up 4) The boom up proportional valve controls the proportional valve secondary pressure according to command output by mechatro controller; consequently the conflux valve of boom main spool and boom on the control valve starts returning. 5) Simultaneously changes values of command to P1 and P2 pumps, and P2 cut proportional valve according to the controlled boom up pilot secondary pressure. 6) And P1 and P2 pumps, and P2 cut proportional valve control the proportional valve secondary pressure to the pressure corresponding to the command output by mechatro controller, and reduce the deliveries of P1 and P2 pumps. 7) The boom main spool and boom conflux valve, and P2 cut proportional valve are switched by mechatro pressure command and changes the deliveries of P1 and P2 pumps, consequently cylinder supply flow rate is gradually reduced during boom up operation in the range of boom up interference area, and ATT smoothly stops. (2) Arm in 4) The arm in proportional valve controls proportional valve secondary pressure according to command output by mechatro controller, consequently the arm main spool on the control valve starts returning. 5) Simultaneously changes values of command to P2 pump and P2 cut proportional valve according to the controlled arm in pilot secondary pressure. 6) And P2 pump and P2 cut proportional valve control the proportional valve secondary pressure to the pressure corresponding to the command output by mechatro controller, and reduce the delivery of P2 pump. 7) The arm main spool and P2 cut spool are switched by mechatro pressure command and change P2 pump delivery, consequently cylinder supply flow rate is gradually reduced during arm in operation in the range of arm in interference area, and ATT smoothly stops. (3) Off-set left 4) The off-set left proportional valve controls proportional valve secondary pressure according to command output by mechatro controller; consequently the off-set main spool on the control valve starts returning. 5) The off-set main spool is switched by mechatro pressure command, consequently cylinder supply flow rate is gradually reduced during off-set left operation in the range of off-set left interference area, and ATT smoothly stops.
