(3) Check of a unit to determine if it is "secure" is usually an external inspection, a hand-feel, or a pry-bar or
wrench check for looseness in the unit. Such an inspection should include brackets, lockwashers, locknuts,
locking wires, or cotter pins used in the assembly.
(4) "Excessively worn" means worn close to or beyond serviceable limits, a condition likely to result in a failure if
replacement of the affected parts is not made before the next scheduled inspection.
b. Reporting Deficiencies. The operator will report all deficiencies on DD Form 110.
c. Before-Operation Services. The following services will be performed to determine if the condition of the
equipment has changed since it was last operated, and to make sure the equipment is ready for operation. Any
deficiencies must be corrected or reported to the proper authority before the unit is put into operation.
(1) Fuel. Check fuel supply. See that fuel tank is full. Check reserve supply of fuel and replenish if necessary.
(2) Water. Check coolant level in radiator and see that it is up to proper level. When filling a cold radiator
containing antifreeze, allow room for expansion. Check water level in the roll ballast. If sprinkler system is
to be used, check water level in the sprinkler tank.
(3) Lubrication. Check oil level. Add oil if necessary. Check hydraulic oil tank supply; add oil if necessary.
(4) Leaks, general. Check for fuel and coolant leaks.
(5) Visual inspection. Check for loose or missing bolts, nuts, screws, loose connections, broken wires, and any
damage that may have occurred since the equipment was last operated.
(a) Disengage master clutch; put forward and reverse clutch lever in neutral.
(b) Clear any obstructions from the path of the roller.
(c) Start engine (para. 28), and adjust equipment to proper operating tempo.
(7) Instruments (gages). Check all gage readings. Normal oil pressure is 30 pounds. Oil pressure will be
above normal while engine is cold. It may drop below normal at idling speed after engine has warmed up. If
oil-pressure indicator shows an unusual drop or no pressure, stop engine immediately and report condition
to proper authority. Coolant temperature gage should show a gradual rise during the warmup period until it
reaches the maximum of 1600 to 180° F. The ammeter should show in charge range. The hourmeter
should register the number of hours that the equipment has been in operation.
