5. Maintenance
5.1. Grease Replenishment/Replacement
Attention
If greasing is performed incorrectly, the internal pressure of the grease bath
may suddenly increase, possibly causing damage to the seal, which would
in turn lead to grease leakage and abnormal operation. When performing
greasing, therefore, observe the following cautions.
① Before starting to grease, remove the plug from the grease outlet.
② Whenever possible, avoid using a compressed-air pump, powered by the
factory air supply. If the use of a compressed-air pump is unavoidable, restrict
the greasing pressure less than 7bar(7kgf/cm
③ Use grease only of the specified type. If not, may damage the reduction gear
or lead to other problems.
④ After greasing, confirm that no grease is leaking from the grease outlet and
that the grease bath is not pressurized, then re-attach the plug in the grease
outlet.
⑤ To prevent accidents caused by slipping, completely remove any excess
grease from the floor or robot.
⑥ When an ambient temperature is more than 40 , be sure to shorten the
period of replenishment in half.
