LUBRICATION INSTRUCTIONS
F-1. Scope.
This appendix provides instructions for lubricating and servicing the APU.
F-2. General.
a.
Intervals (on-condition or hard time) and the related man-hour times are based on normal operation. The man-
hour time specified is the time you need to do all the services prescribed for a particular interval. Change the hard time
interval if your lubricants are contaminated or if you are operating the equipment under adverse operating conditions,
including longer-than-usual operating hours. The hard time interval may be extended during periods of low activity. If
extended, adequate preservation precautions must be taken.
b.
Lubrication points are indicated by arrow shafts on the equipment.
c.
The lowest level of maintenance authorized to lubricate a point is Unit Maintenance (C).
F-3. Oil Servicing Procedures.
a.
Unlock lid latches and open APU front lid.
b.
Remove engine oil dipstick. Wipe clean and reinsert into engine. Remove dipstick and check oil level.
c.
High mark on dipstick indicates "full" condition. Oil level on dipstick must fall between high and low marks.
CAUTION
Always wipe clean oil filler components before starting your lube service. Never
use the wrong type or grade of oil. Never use too much oil, as overfilling will
cause spillage and harm engine components.
d.
If oil level is low, remove oil filler cap. Fill engine with up to 2.5 quarts of engine lubricating oil as specified. Pour
oil slowly to prevent overflow.
e.
Using engine oil dipstick, check for proper oil level.
