Section III. MAINTENANCE PROCEDURES
This section contains the operator maintenance procedures for repair of the M2, M2A and the M2A with Safety Device
generators. Refer to TM 10-7360-281-13&P operator maintenance procedures for the Modern Burner Unit (MBU)
a. General. The purpose of the generator is to filter and vaporize the fuel when using leaded or unleaded fuel. Two
(2) pounds of steel wool is packed inside the generator to accomplish the filtering of the fuel. To vaporize the fuel, the
generator must be hot to convert the liquid fuel to a vapor and this is primarily done by thepreheater, and after the
burner is ignited the heat from the burner keeps the generator hot. The normal life expectance of the generator, when
using leaded fuel, is 450 to 500 hours. Due to carbon buildup and gasoline lead deposits replacement is required,
usually during this time frame.
b. Removal. Refer to figure 3-1.
(1) Make sure the unit is off and cool.
Do not release pressure near any open flame or while unit is hot.
(2) Loosen the fuel filler cap (1) to release air pressure.
(3) Remove top shield by unhooking four springs (2) securing the shield (3) to the burner unit (4).
Remove the shield.
(4) Remove flame valve knob (5) and place in holder (6).
(5) Loosen nut (7) at rear of generator (8) and slide generator forward slightly and lift generator from burner.
(6) Remove fuel feed tube (9) located under nut (7).
Avoid breathing dust or fumes or placing generator to mouth. Never try to
blow air through the generator to remove any matter. Dust and fumes could
cause lead poisoning. Always bury an unserviceable generator if in combat
and follow local policy during peacetime.
