PREVENTIVE MAINTENANCE CHECKS AND SERVICES INCLUDING
LUBRICATION INSTRUCTIONS -- CONTINUED
Lubrication Instructions -- Continued
When AOAP analysis is not available and OE/HDO is used, change engine oil and filters at 150 hours or 1500 miles
(2413 km) of operation, or Semiannually (whichever comes first). If Engine Oil, Arctic (OEA) is used, change en-
gine oil and filters at 75 hours or 750 miles (1207 km) of operation (whichever comes first).
When AOAP analysis is not available, change transmission oil and filters at 150 hours or 1500 miles
(2413 km) of operation, or Semiannually (whichever comes first).
Always use the Expected Temperature Lubrication Table to determine seasonal lubrication requirements. When
changing engine and transmission oil due to seasonal requirements, always change the oil filters.
Sound maintenance practice dictates that AOAP is not a maintenance substitute, but is used as an effective mainte-
nance diagnostic tool. Therefore, if 12 months have elapsed since the last AOAP or seasonally directed oil and
filter change, the oil and filters will be changed.
Clean parts with SOLVENT, DRY--CLEANING (P--D--680) (item 1, WP 0716 00).
