The grease nipple position is shown in Fig. 5-6. The lubrication specifications for each place are shown in Fig. 5-6［Caution］

・ The brands of grease given in Table 5-5are those filled when the robot is shipped.

・ The lubrication time is a cumulative value of the operation at the maximum speed. If the operation has been suspended, or if the designated speed is slow, the lubrication time can be lengthened in proportion.

(The "Lubrication interval " in Table 5-5is usually based on the three-year inspection. 8Hr x 20 days x 36 months = 6000Hr.）

・ Depending on the robot operation state, the lubrication time will fluctuate, so determine the time according to the state so that the grease does not run out.

・ With the maintenance forecast function of the personal computer support software (option), the guidance of lubrication time is calculated according to the operating environment of the customer.

・ The numbers in the correspond to the supply positions in Fig. 5-6.

・Avoid excessive lubrication since it may lead to grease leak. Also, the number of lubrications is limited to 3 times.

(2)Lubrication method
