Inspection and maintenance

2.2 Periodic inspection (Weekly/Monthly)

In addition to daily inspection, periodic inspections (weekly and monthly) are essential to ensure safe and

efficient use of the machine.

We recommend setting an earlier inspection interval if parts are subject to frequent usage.

2.2.1 Parts to be replaced during periodic replacement

If parts need to be replaced as a result of the periodic inspection, use the spare parts listed below.

CAUTION

The part Nos. given in this manual are the original part Nos. which were assigned to the parts when this manual was

issued. Because these part Nos. may be changed without prior notice, be sure to verify the latest part Nos. before

ordering parts.

2.2.2 Recommended grease

When lubricating axis ball screws and linear guides according to the periodic inspection checkpoints, use only

the grease stated in the list below.

Recommended grease

Lubrication point Grease name YAMAHA part No. Notes

Ball screws and leaner guides of all axes

Precautions when handling grease

WARNING

INFLAMMATION MAY OCCUR IF GREASE OR LUBRICANT GETS IN THE EYES. BEFORE HANDLING THE GREASE, WEAR SAFETY

GOGGLES TO ENSURE THE GREASE WILL NOT COME IN CONTACT WITH THE EYES.

WARNING

INFLAMMATION MAY OCCUR IF THE GREASE OR LUBRICANT COMES INTO CONTACT WITH SKIN. BE SURE TO WEAR

PROTECTIVE GLOVES TO PREVENT CONTACT WITH SKIN.

WARNING

DO NOT TAKE ORALLY OR EAT THE GREASE OR LUBRICANT. EATING WILL CAUSE DIARRHEA AND VOMITING.

CAUTION

When storing the grease after use, tightly close the cap of the grease tube or container to prevent dust and moisture

from entering inside. Store it in a dark place to avoid direct sunlight, and keep away from ﬁre and heating sources.

2.2.3 List of periodic inspection checkpoints

Use the inspection check sheet to periodically inspect the machine.

The inspection check sheet describes the contents of the inspections to be performed weekly or monthly in

addition to the daily inspection described in the previous section.

Make a copy of the inspection check sheet (sample) stated on the next page and use it for the periodic

inspection. Or, it is recommended that the customer prepares an appropriate inspection sheet in such format

and properly perform the periodic inspection with it.

CAUTION

Periodic inspections must be performed by or under the direction of person who has received training from YAMAHA

or a YAMAHA sales representative.

CAUTION

Warm up the machine and wipe away excess grease before greasing up the lubrication points.
