Inspection and maintenance
Before beginning work
In most cases, the maintenance work should be performed with the main power turned off.
However, some maintenance tasks are performed under emergency stop conditions with the power turned on.
In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance work.
The power is turned on during maintenance where any servo-axis must be operated or machine operation
must be checked. In this case, also ensure adequate safety before beginning the maintenance.
When operating the machine, make sure the following conditions are satisfied.
n
Operating conditions
1. The supply air pressure is kept at its correct level.
2. All the safety covers are closed.
Be sure to observe the following precautions when performing the inspection or maintenance work.
n
Precautions
• Periodic inspection or maintenance work must be performed by or under the direction of person who has received
training from YAMAHA.
• Always turn off the power to the machine before inspecting mechanical components. If the power to the machine
needs to be turned on during inspection, make sure that no part of anyone's body comes within the machine movement
range.
• Be careful not to allow any foreign matter to enter the machine during inspection or maintenance work.
• Use only the lubricants and grease specified by YAMAHA or a YAMAHA sales representative.
• When replacing parts, always use parts approved by YAMAHA or a YAMAHA sales representative.
• Do not modify any parts in the machine. Modification may result in poor performance or threaten operator safety.
