Inspection and maintenance
1. Precautions
For safe, effective inspection and maintenance, be sure to observe the
following precautions.
1. Periodic inspections must be performed by or under the direction of person
who has received training from YAMAHA or a YAMAHA dealer.
2. 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 or maintenance, make sure that no part of anyone’s body comes
within the machine movement range.
3. Be careful not to allow any foreign matter to penetrate inside the machine
during inspection.
4. Use only the lubricants and greases specified by YAMAHA or YAMAHA dealer.
5. When replacing parts, always use only parts approved by YAMAHA or a
YAMAHA dealer.
6. Do not modify any parts in the machine. Modification may result in poor
specifications or threaten operator safety.
