Greasing
The ball screw spline and reduction gear units need greasing regularly. Only use
the grease specified.
Parts and Interval when the greasing is necessary have been described. Refer to
the manipulator manual for details of the greasing procedure.
Keep enough grease in the Manipulator. Operating the
Manipulator with insufficient grease will damage sliding parts and/or
result in insufficient function of the Manipulator. Once the parts
are damaged, a lot of time and money will be required for the
repairs.
CAUTION

instructions below.
If grease gets into your eyes :
Flush them thoroughly with clean water, and then see a doctor
immediately.
If grease gets into your mouth :
If swallowed, do not induce vomiting. See a doctor immediately.
If grease just gets into your mouth, wash out your mouth with
water thoroughly.
If grease gets on your skin
Wash the area thoroughly with soap and water.
