PREPARING M1114 TRUCK
4-22. Prepare the M1114 truck as described below.
• Prepare the fuel tank as shown in Figures 3-5 and 3-6.
Note. Certain units may be authorized a waiver allowing 95% fuel. One way to verify the tank
is 95% full is to fill the tank and withdraw 1 ¼ gallons with a hand pump.
CAUTION
A full tank does not allow for expansion, and is a danger to aircraft and
air crew.
• Make sure the batteries and battery compartment comply with AFMAN 24-204(I)/TM 38-250.
• Prepare the cab of the truck as shown in Figures 4-2, 4-3 and 4-28.
• Prepare the body of the truck as shown in Figure 4-29.
• Prepare the underside of the truck as shown in Figure 4-30.
• Prepare the front of the truck as shown in Figure 4-31.
• Prepare the turret housing as shown in Figure 4-5.
• Prepare the light vehicle obscuration smoke system (LVOSS) units as shown in Figure 4-32.
