Table 2. Lubrication Chart
Inspection requires checking for visible signs of oil leakage,
draining, replacing and adding oil to ensure appropriate oil
level requirements. Refer to paragraph 4.3 for procedure
and recommended intervals between inspection.
Excessively dirty oil will require fresh oil replacement. If oil
leakage is found to be excessive, determine cause and per-
form required corrective action. Periodic inspection proce-
dures can be less frequent after first or second scheduled
inspections.
