Inspection and maintenance
1. Precautions
Be sure to observe the following precautions when performing the inspection or maintenance work.
• 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.
