Charging the EZ-Start Battery

The included charger can be
used to charge the included
EZ-Start battery pack.

Do not charge batteries inside of an

automobile. Read the Safety Precautions

section of this guide.

Plug the charger into a 12-volt
automotive auxiliary power socket.

The charger is compatible with 12-volt
automotive auxiliary power sockets only.
The LED on the charger will glow red to
indicate it is ready to charge a battery.

2. Connect the battery to begin charging.

Plug the battery into the charger. The
charger’s LED will flash green, indicating
that charging has begun. The flashing
green LED on the charger indicates the
charge progress.

3. Disconnect the battery

when charging is
complete.

When the

battery is fully charged,
the LED will light solid
green. The battery will
be warm in your hand.
Disconnect the battery.

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 T-Maxx 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.

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.

Use a Strong Starter Battery
A weak starter battery, or one that has not been fully charged, may not
deliver enough power to crank the engine over at the appropriate rpm to
keep the piston from sticking at top dead center (TDC). A new engine will
typically have a tight fit between the piston and the top of the sleeve. This
is a tapered fit, and a tight piston sleeve fit on initial startup is desirable
for those who want the best-performing engine. Make sure you are using
a good quality battery pack that is fully charged (new batteries usually
require several charge cycles to reach peak voltage and full capacity). This
is especially important with a new engine that needs to be broken in. If the
engine sticks at TDC, see page 28 for instructions on freeing the engine.

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. 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 exhaust pipe after running, it can
become very hot.

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 EZ-Peak Plus, part #2970. 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.

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.
