Take the following precautions when performing 6-month inspection.

WARNING

Injury can occur if hands or fingers are squeezed between the drive pulley and belt. Always turn off the controller and use caution when handling these parts.

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, spline shaft and linear busing 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.

WARNING

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 ig- nite.

!CAUTION

Unless grease specified by YAMAHA is used, the service life of the ball screw, ball spline and linear bushing shaft will shorten.
