2.1 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.

2.1.2 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.
