The following section addresses some very basic engine and
radio questions you may have about your T-Maxx.Most questions
arise from simple user errors or minor adjustments that are easy
to correct. If you can’t find a solution for your T-Maxx here, then
visit our Web site at www.traxxas.com and click on the Customer
Support menu.There you will find a much more extensive and
detailed online troubleshooting area.In addition, you may call
Traxxas Customer Service at 1-888-TRAXXAS (outside US
call 972-265-8000).
Radio system does not work properly:
If the power light on the transmitter does not come on,check
for proper battery installation and that the batteries are new
and/or fully charged.If the power light is blinking, then the
transmitter batteries are weak and should be replaced.See
page 13 for more details.
If the transmitter light is on but the radio is still not
responding,check for proper installation of the receiver
batteries and that the batteries are new and/or fully charged.
Check to make sure the on/off switch on the model is in the
on position.Finally,if there is still no response check the red
and black wires that connect the battery pack to the “batt”
terminal on the receiver (you will have to remove the receiver
cover). Make sure the wires are not pinched or damaged and
that the plug is secure in the receiver.See page 14 for more
details.
Short radio range:
If the radio range appears short, then first check to make sure
the transmitter antenna is fully extended and that the
antenna in the T-Maxx is in place and has not been cut or
damaged.Next, make sure the batteries are all fully charged.
Finally, if you are still experiencing short range,try a different
location.Sometimes there can be interference from various
sources that can cause your radio to malfunction.
The transmission is stuck in neutral
(neither forward or reverse is engaged):
Do not rev the engine.Revving the engine with no load can
cause serious internal damage to the engine, such as a broken
connecting rod.Move the shift button back and forth until a
gear is selected.
The transmission will not shift between forward and reverse:
Reduce the engine idle speed.The engine idle speed should
be set as low as possible and still allow reliable running.If the
idle speed is too high, the T-Maxx will not shift.
Unload the driveline.If the T-Maxx driveline is heavily loaded,
as it might be when stuck on an incline or against an object, it
may not shift into reverse.
Engine will not spin (EZ-Start will not turn the engine):
If neither LED on the controller lights,the EZ-Start battery
could be discharged or improperly connected.Inspect and
recharge if necessary.
If the glow plug LED lights and the motor LED does not,then
the EZ-Start controller is in protection mode. Allow the
controller to cool for at least three minutes.The circuitry
should automatically reset.
Check to make sure the wires are connected to the EZ-Start
motor in the T-Maxx.The red wire should connect to the
positive motor terminal,indicated by a red dot next to the
terminal.
The engine could be flooded.If too much fuel accumulates in
the combustion chamber at start up,the engine will
hydraulically lock.Follow the procedure on page 43 for
clearing a flooded engine.
Check for binding at the engine flywheel.If you are not able to
turn the engine by hand,the engine could be flooded,there
could be binding in the clutch system, or there could be
internal engine damage.(Note: It is normal for the engine to
be extremely tight and hard to turn when the piston reaches
the top of the compression stroke.)
The T-Maxx shudders or jerks during acceleration:
This occurs when the T-Maxx is accelerated slowly.The
engagement pawls inside the transmission use centrifugal
force to operate.The engine must be turning above a certain
RPM before the pawls will swing out and engage.If the engine
is run at just below engagement RPM the truck will appear to
