All of us at Traxxas want you to safely enjoy your new E-Maxx.
Operate your E-Maxx sensibly and with care, and it will be
exciting, safe, and fun for you and those around you. Failure to
operate your E-Maxx in a safe and responsible manner may
result in property damage and serious injury.The precautions
outlined in this manual should be strictly followed to help
ensure safe operation.You alone must see that the instructions
are followed and the precautions are adhered to.
Important Points to Remember
The truck is not intended for use on public roads or
congested areas where its operation can conflict with or
disrupt pedestrian or vehicular traffic.
Never, under any circumstances, operate the truck in crowds
of people.The truck is very fast and could cause injury if
allowed to collide with anyone.
Because the truck is controlled by radio, it is subject to radio
interference from many sources that are beyond your
control. Since radio interference can cause momentary
losses of radio control, always allow a safety margin in all
directions around the model in order to prevent collisions.
The motors, batteries, and speed control can become hot
during use. Be careful to avoid getting burned.
Don’t operate your E-Maxx at night, or anytime your line of
sight to the model may be obstructed or impaired in any way.
Most importantly, use good common sense at all times.

Quick Start: Getting up to Speed

The tires on your E-Maxx must be glued to the rims using CA
tire glue to prevent the rims from spinning inside the tires.You
can glue the tires without removing the wheels from the truck.
For clarity, these instructions show the process with the wheels
removed.
1. Remove a wheel from the
E-Maxx using the larger
(8mm) end of the glow plug
(universal) wrench.
2. Use your thumb to push the
side of the tire away from the
rim. Place one or two drops of
CA glue into the opening and
release the tire. Capillary
action will draw the glue
around the bead of the tire.
3. Repeat step two at four or five points around the rim, until the
tire is completely secured to the rim.Turn the rim over and
repeat the process for the inside of the rim/tire. Repeat for the
other 3 wheels.
4. Reinstall the wheels, making
sure none of the axle pins
have fallen out from behind
the hex hubs.
Always wear safety
glasses to prevent
glue from splattering
into your eyes.
The acetone in
fingernail polish
remover will
remove excess glue from
your fingers.

Decorating Your E-Maxx
Applying The Decals
The ProGraphix painted
body is covered with a
protective film for shipping.
You must remove this film
before applying any decals.
To remove the film, lift a
corner of the film and
carefully pull it off the body
in one continuous piece.
Your E-Maxx decals are die-
cut for easy removal. Use a
hobby knife to lift the
corner of a decal and lift it
from the backing.
Carefully position the decal
over the desired location
and press one side on the
body. Pull the decal tight
and use a finger to gradually
smooth out any air bubbles
as you apply the decal.
Look at the photos on the box for typical decal placement.
