FUEL:
Fuel leaks are dangerous. Inspect the TQG for leaks before, during
and after operating it. If you ±nd any,
shut down the TQG
and report the problem to
±eld maintenance.
Dirt and debris in the fuel system make the engine run rough. They can cause
engine speed to vary. And that can spike voltage and damage equipment powered by
the TQG. Remove the fuel tank ±ll cap. Remove the
mesh fuel strainer
and wipe it
clean. Also inspect your
plastic fuel cans.
Make sure the caps are screwed on snug.
Covering the cans with a tarp helps keep dirt, debris and water out of the fuel, too.
The
fuel/water separator
removes water and sediment from the fuel. Open the
drain cock and drain the contaminants into a container. Inspect the fuel/water separator
for leaks, cracks and loose fuel lines before and after running the TQG. If you ±nd any
damage, report it to ±eld level maintenance.
When the TQG’s running, keep an eye on the
FUEL LEVEL
indicator on the
control panel and the
NO FUEL
fault indicator. Never allow the fuel tank to run dry
while the TQG is running. That can drain the batteries and damage the fuel pump.
Depending on which TQG you have, its fuel tank holds 4 or 5 gallons, enough for
about 8 hours of operation.
Refuel if the indicators show the fuel level is low.
Shut down the generator
set before refueling.
Never refuel while the engine is running. Read your TM’s
WARNINGS about ±lling the fuel tank.
HEAT:
A running engine creates heat. This heat needs to be released into the
surrounding air to reduce engine temperature. Problem is, heat releases more slowly in
hot weather than in cooler weather. That means engine temperature stays high longer.
The result: The engine overheats and may stop running altogether. During hot weather,
take precautions to avoid engine overheating.
If you put the
TQG in a
revetment,
give it plenty of
air. Center the TQG with at
least 4 feet between it and
the walls.
Another way to keep the
TQG cooler is to put it under
a
solar shade.
Solar shades
block out the sun and reduce
hot surface temperatures.
Heat and the 3-kW TQG
Before you run the 3-kW TQG,
inspect the
air intake ducts, exhaust
ducts
and
air ±lter
for clogging dirt
and debris. A clogged air intake or
±lter chokes off air to the engine,
making it work harder. The results
are
overheating
and
shutdown.
Remove
clogs
from
the
ducts.
Clean the ±lter with compressed air.
Replace it if necessary.
Keep the
access doors
closed. That allows air to ²ow around inside and cool the
generator. Closed doors also keep dirt and sand away from the engine.
Keep an eye on the
ENGINE HIGH TEMP
fault indicator on the control panel.
If the indicator shows the engine’s running hot, the problem could be a clogged air
±lter or air intake ducts. Or the generator could be overloaded.
Read the operator’s troubleshooting table for instructions.
