Using The Ez-Start; Protection Mode; Shutting Off The Engine; Clearing A Flooded Engine - Traxxas Revo 5310 Owner's Manual

Using the EZ-Start

Your EZ-Start controller plugs into a 4-prong receptacle in the center of
the pickup bed on your Revo. When the red button on the controller is
pressed, the EZ-Start motor begins to spin the engine and power from
the control unit heats the glow plug. Assuming all settings and
preparations are correct, the engine should start almost immediately.
Each of the two status indicator LEDs on
the hand-held control unit, the Motor
LED and the Glow Plug LED, should
light green while starting. If either LED
fails to light while starting, there is a
fault indicated with that function:
If the Glow Plug LED fails to light,
the glow plug may be bad, or the
glow plug wire may be damaged or
disconnected.
If the Motor LED fails to light and the
starter fails to operate, then the
EZ-Start is in protection mode.

Protection Mode

The EZ-Start uses Smart Start ™ technology to monitor the condition of
the system and detect failures. The controller monitors the load being
placed on the EZ-Start motor. If the load becomes excessive, the system
shuts off power to the motor to prevent costly damage to the motor and
the controller. This may occur, for example, if the engine floods with fuel
during starting. The starter spins at first but when excessive fuel in the
combustion chamber begins to lock up the engine, the starter motor
slows under the heavier load. This causes the protection circuit to shut
off the power to the motor. Allow at least 3 minutes for the starter motor
to cool and the circuit to automatically reset before continuing. Use the
time to find and eliminate the condition that caused the excessive load
on the starter motor.

Shutting Off The Engine

Turning off the switch for the radio will
not shut off the engine. To shut off the
engine, use the shut-off clamp on the
fuel line. Simply squeeze the clamp
closed to shut off the fuel supply to the
engine. Don't forget to release it when
you restart the engine.
Avoid shutting off the engine by placing your finger over the exhaust
outlet, especially if you are through driving for the day. This will leave
more unburned fuel in the engine that could lead to harmful corrosion.
Always be careful not to touch the metal exhaust pipe after running, it
can become very hot.

Clearing a Flooded Engine

If the engine is primed for too long during startup, then it can
become flooded with fuel. When the engine is flooded it will no
longer turn due to excess fuel in the combustion chamber preventing
upward movement of the piston. Use the following procedure to clear
a flooded engine.
1. Remove the blue glow plug wire.
2. Remove the glow plug and gasket with the glow plug wrench
supplied with your model. A 5/16 nut driver will also work.
3. Turn the model upside down and plug in the EZ-Start controller.
4. Push the EZ-Start button for several seconds to clear the engine of
excess fuel.
5. Turn the model over and reinstall the glow plug and gasket.
6. Reconnect the blue glow plug wire to the glow plug.
7. Reconnect the EZ-Start controller
8. Do not prime the engine. Pull the throttle to 1/2 throttle and push the
EZ-Start button. The engine should start immediately.
When the EZ-Start
controller is in protection
mode, wait at least three
minutes before attempting
to start the engine, to give
the starter motor time
to cool.
It's normal for your EZ-Start
controller to become warm
after repeated use.
