Traxxas 48077 - Manual (Page 22)

22 • NITRO 4-TEC 3.3
The Traxxas EZ-Start brings the convenience of push-button electric
engine starting to your Nitro 4-Tec. The EZ-Start consists of a hand-held
control unit and an on-board motorized starter.
• Power for the EZ-Start system comes from a 7.2-volt rechargeable battery
pack installed in the hand-held control unit.
• The engine glow plug is heated automatically by the EZ-Start system,
eliminating the need to keep up with a separate glow plug igniter.
• The voltage to the glow plug is kept constant, regardless of the
load placed on the starter by the starter motor.
• The “Glow Plug” LED (light emitting diode) on the control unit
indicates the condition of the glow plug.
• The “Motor” LED indicates the status of the EZ-Start electric starter motor.
• The cush drive mechanism in the drive unit prevents damage to the
gears caused by engine kickback.
• Smart Start ™ protection circuitry prevents damage to the motor by cutting
power if the load on the motor or other electronics exceeds safe limits.
Charging the EZ-Start Battery
The included charger can be used to charge the included EZ-Start
battery pack.
1. Plug the charger into the wall. The LED on the charger should
glow green.
2. Connect the included EZ-Start battery pack to the charger output
cord. The LED will glow red indicating the battery is charging.
3. The battery should charge for approximately 4 ½ hours. The LED
will turn green when the battery is fully charged.
Installing the EZ-Start Battery
1. Press the tab in the end of the battery
compartment door to open (A).
2. Plug a fully charged
7.2-volt battery pack
into the connector
inside (B).
3. Twist the battery two
or three times to twirl
the battery plug wires. This
helps hold the wire and
battery in place when the
battery is installed in the
compartment (C).
4. Install the battery into the
compartment and press the wires securely into place.
5. Snap the battery compartment door back on and lock the
end tab (D).
Using the EZ-Start
Your EZ-Start controller plugs into a 4-prong receptacle in the center of
the bed on your Nitro 4-Tec 3.3. 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.
Using Other Chargers
Another convenient option
for charging the included
battery is an AC peak-
detecting charger that
plugs directly into an AC
wall outlet, such as the
TRX Power Charger, Part
#3030X. It contains special
peak-detection circuitry
that automatically shuts the
charger off when the battery
is fully charged.
Caution: Never use a
15-minute timed charger to
recharge your model’s battery
packs. Overcharging may
result, causing damage to the
battery packs.
