1. TRANSMISSION OIL LEVEL CHECK.
While performing engine warm-up,
make sure personnel stand well clear
suddenly, causing severe injury or
death to personnel.
Do not check oil with engine running.
Do not overfill.
Transmission and engine contain preservative oil
upon receipt. Preservative engine oils PE1 and
PE2 are identical to engine oil OE-40, except
they contain a preservative additive. PE1 and
PE2 will be used in the same manner as the
regularly used engine oil OE-40. PE1 or PE2 will
also be used in the transmission until the first
scheduled 2000-mile or semiannual oil change.
Check oil level before starting engine. Oil level
indicator must be within 'OPERATING RANG E"
stamped on dipstick and filler cap (1). Add or
drain oil (see key for required type) as required.
Block vehicle tracks. With brakes applied and
transmission in fourth gear, run engine at 1600-
1900 rpm to warm the transmission oil. When
transmission oil temperature gage reads over
180°F, run engine at 1200-1600 rpm for 1-3
minutes with transmission in neutral (N). After
this period of time, oil temperature should
stabilize between 180"F and 220°F. Stop
engine, wait 3-5 minutes, then check oil level.
