When the tank is full, the line pressure will rap-
idly spike and the flow rate will fall. When a pres-
sure rise or flow rate drop is observed, close the
station’s fill valve, if equipped.
NOTE: Do not over-fill an LNG tank. If the ul-
lage tank is completely filled during fueling, tank
standby time will be reduced to zero and the
primary relief valve will open almost immediately
after fueling.

Disconnect the station hose from the tank fuel fill
fitting.
9.
Disconnect the electrical ground clamp and cable
from the fuel tank.
10. Install the dust cap on the tank fuel fill fitting.
Natural Gas Detection System
A gas detection system is standard equipment in all
Daimler Trucks natural-gas-fueled vehicles. This sys-
tem has a sensor in the engine compartment and
one in the cab, both situated in high areas to detect
natural gas buildup as a result of leaks.
The AMGaDS III Plus is a natural gas detection sys-
tem. This device is meant to serve as a supplemen-
tal warning only. It is not intended to replace stan-
dard safety practices that should be conducted
around flammable gases.
IMPORTANT: To function properly, the gas de-
tection system must be powered at all times.
The gas detection system is directly powered by
the batteries, and can only be powered off by
disconnecting the batteries.When servicing a
natural-gas-fueled vehicle, disconnect the bat-
teries only when necessary, and do not leave
the batteries disconnected for extended periods
of time.
The lower flammability limit (LFL) is the smallest
amount of the gas that supports a flame when mixed
with oxygen and ignited. Zero percent (0%) LFL indi-
cates a gas-free atmosphere. One hundred percent
(100%) LFL indicates that gas concentration has
reached its lower flammability limit (5% gas in air by
volume). The red warning light and audible alarm
located in the overhead console activate when a sen-
sor detects gas fumes in concentrations above 50%
LFL, and should allow ample time to utilize safety
procedures. However, individuals with special needs
should review the system with a professional safety
engineer.
Alarm Procedure
Before operating the vehicle, the driver must be fa-
miliar with the procedures as shown on the interior
sticker on the overhead panel (
Fig. 19.4
) and the
exterior sticker on the door (
Fig. 19.5
).
IMPORTANT: If an audible alarm activates, do
not operate any electrical switch, including
lights. Avoid causing sparks and stay away from
arcing switches and equipment. Do not use a
telephone, including cellular phones or any
types of portable communication or electronic
devices that have a battery.
