Six-Month Inspection

Take the following precautions when performing 6-month inspection.
WARNING
The Z-axis will slide down when the Z-axis brake is released, causing a hazard-
ous situation. Do not release the brake when lubricating the Z-axis parts.
When lubricating the ball screw and spline shaft, observe the following precautions.
WARNING
Precautions when handling grease:
• Inflammation may occur if this gets in the eyes.
Before handling the grease, wear your safety goggles to ensure the grease
will not come in contact with the eyes.
• Inflammation may occur if the grease comes into contact with skin. Be sure
to wear protective gloves to prevent contact with skin.
• Do not take orally or eat. (Eating will cause diarrhea and vomiting.)
• Hands and fingers might be cut when opening the container, so use protec-
tive gloves.
• Keep out of the reach of children.
• Do not heat the grease or place near an open flame since this could lead to
sparks and fires.
Emergency Treatment:
• If this grease gets in the eyes, wash liberally with pure water for about 15
minutes and consult a physician for treatment.
• If this grease comes in contact with the skin, wash away completely with
soap and water.
• If taken internally, do not induce vomiting but promptly consult a physician for
treatment.
Disposing of grease and the container:
• Proper disposal is compulsory under federal, state and local regulations. Take
appropriate measures in compliance with legal regulations.
• Do not pressurize the empty container. Pressurizing may cause the con-
tainer to rupture.
• Do not attempt to weld, heat up, drill holes or cut this container. This might
cause the container to explode and the remaining materials inside it to ignite.
CAUTION
!
Unless grease specified by YAMAHA is used, the service life of the ball screw
and ball spline will shorten.
