2. Operating with tracks adjusted wrong.
 Tracks on M107, M110 and M578
 should be adjusted like shown in Fig
 63, Ch 2 to TM 9-2320-238.10.

 3. Operating with brakes adjusted wrong.
 or pulling to one side, have your unit
 MWO 9-2300-216-30/1 (Mar 64) and
 2320-238-20, para 51a.

 S(1.) Check cable slack and tight adjustment as given
 in MWO.

 (2) With brakes released, index pins should line up
 at "release" mark.
 S (3) With fully applied brakes, index pins should be
S between apply and adjust and still be alined.

 (4) If pins are not alined, or go to or beyond
 adjust mark re-adjust brakes.

 S 4. Moving out without a properly warmed
 engine. Always, but always, warm up
 your engine before moving out. When
 the engine catches good and runs
 smoothly, set the hand throttle control
 to run between 1000-1200 RPM. Run
 for about five minutes until the tem-
 perature gage begins to rise. Coolant
 temperature should level off between
 1700-1850F. More details are covered
 in Ch 7, TM 9-2300-216-10 and para
 16a, Ch 2, TM 9-2320-238-10.

 5. Stopping without cooling engine. Before engine shutdown, make sure your cool-
 ant temperature is between 170 and 185"F. If it's higher, set your hand throttle
 and idle between 1000 and 1200 RPM. This should bring it down to the right
 temperature range. If it takes longer than five minutes to cool off, then you
 better check out the engine like it says in Table II, item 7, TM 9-2300-216-10
 or item 7, Table I, TM 9-2320-238-10.
