Kawasaki Robot Precautions Inspection and Maintenance Manual 1.0 PRECAUTIONS Prior to starting maintenance on a Kawasaki robot, pay attention to the following matters to ensure safety WARNING Prior to starting maintenance, turn OFF the controller power switch and the external power switch for shutting off power supply to the robot controller Display signs indicating clearly “Inspection and maintenance in progress”, and lockout/tagout the external power switch to prevent accidents of electric shock, etc caused when personnel accidentally turns ON the power If changing the joint angle is required for grease replenishment, etc., first, turn ON the motor power Then, set the arm to the specified pose Be careful not to be caught by or between any moving parts of the arm due to careless approach to the arm at this time After moving the arm to the desired pose, turn OFF the controller and external power Display signs indicating clearly “Inspection and maintenance in progress”, and lockout/tagout the external power switch before starting maintenance Some arm parts may be very hot after continuous operations, depending on ambient temperature when conducting maintenance immediately after the continuous operations Be sure the arm has cooled before starting any work Handling hot machine parts is extremely dangerous and may result in injury, burns, etc Warning labels are affixed to the arm to identify areas with possibility of electric shock, high temperature or pinching, so check these areas beforehand See the next pages for the warning labels and their positions CAUTION Do not apply excessive force to the robot arm while robot is not operating Applying excessive force may result in a shortened service life and/or damage to parts or the brake mechanisms in the joints Use only Kawasaki designated greases and other lubricants For replenishing and replacing grease, use manual type grease gun When using air pump type grease gun, reduce air pressure on the supply side to 0.26 Mpa (2.5 kgf/cm2) or lower by a regulator, etc and apply grease using grease pump P3L (manu by Macnaught, pump ratio 50:1, part No.:50154-0349) (When using all other grease pump models/brands, contact Kawasaki before using.)

the cap from the gas inlet of gas spring Attach the gas pressure checking jig on the gas inlet and check the pressure For the specified pressures of the gas, see the next page Remove the jig after checking the pressure Gas inlet cap Gas inlet Gas pressure checking jig Surface temperature check [ NOTE ] Two gas springs are mounted for BT200L/BT165L Internal pressure decreases by approx 0.05 MPa each time the gas pressure is checked Replenish gas at approximately sixth check 47 B Series Kawasaki Robot Check of Gas Spring Inspection and Maintenance Manual NOTE* If it is not possible to confirm the JT2 posture is minus 115º by Teach Pendant, make the match mark of the moving side face vertical direction shown below Rated pressure of gas spring See the figure below for the rated pressure of the gas spring Measure the surface temperature of the gas spring using a radiation thermometer (HORIBA, model: IT540-W or equivalent) Rated reference pressure of gas spring Rated pressure [MPa] Rated lower limit pressure of gas spring Rated upper limit pressure of gas spring Surface temperature of gas spring [C ] [ NOTE ] If the gas pressure exceeds upper/lower limit of rated pressure, discharge/ replenish gas and adjust the gas pressure so that the gas pressure is within the upper/lower limit range 48 B Series Kawasaki Robot Check of Gas Spring Inspection and Maintenance Manual 8.2 GAS REPLENISHMENT Replenish the nitrogen (N2) gas whose content of nitrogen is 99.99 V/V % or more if the gas pressure is below the specified lower limit [ NOTE ] Check the gas pressure 24 hours after the replenishment of nitrogen gas Replace the gas spring if the gas pressure is below the specified lower limit BX100L, BX130X, BX165N, BX165L, BX200L, BX250L, BX300L Procedure Move the robot so that the posture of JT2 becomes minus 5º, then turn OFF the power Remove the cap from the gas inlet of gas spring and attach a gas replenishment coupler Attach the gas replenishment jig on a nitrogen gas
