* Inspection requires checking for visible signs of oil leakage, draining replacing and adding oil to ensure appropriate oil
level requirements. Excessively dirty oil will require fresh oil replacement. If oil leakage is found to be excessive, refer to
appropriate troubleshooting information and perform applicable corrective action. Periodic inspection procedures can be
less frequent after first or second scheduled inspections.
** Initial oil change requirements include flushing gear boxes with a standard cleaning agent.
