5-11.1 Hard time intervals 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 interval if your lubricants are
contaminated or if You are operating the equipment under adverse operating condi-
tions, including longer-than-usual operating hours. The interval may be extended
during periods of low activity. If extended period of low activity is anticipated,
adequate preservation precautions must be taken.
5-11.2 On-condition (OC) intervals for oil changes shall be determined by the Army

Dry cleaning solvent, P-D-680, used to clean parts is potentially dangerous
to personnel and property. Avoid repeated and prolonged skin contact.
Wear solvent impermeable gloves and eye/face protective equipment when using
solvent. Do not use near open flame or excessive heat. Flash point of
solvent is 100 F to 138 F (38 C to 59 C).
