SAFETY PRECAUTIONS

❍ 3. Remove the antenna tube from the parts bag. Run the anten­na through your fingers a few more times to straighten the receiv­er antenna wire. Thread the receiver antenna wire through the
antenna tube. Press fit the antenna tube into the antenna holder
which is located on the throttle servo mount. Do not cut or coil

the receiver antenna wire.

❍ 4. Remove the air filter from the parts bag. Remove the 3 air
filter elements from the air filter housing and soak the air filter
elements with air filter oil (not included) and then squeeze the
excess oil from the elements. A light shock oil ma y be used or you
can purchase special air filter oil from most hobby shops. Place
the air filter elements back into the air filter housing, and then
install the air filter assembly onto the top of the carburetor.

❍ 5. Remove the two 3x10mm screws from the receiver battery
case which is located on the rear of the truck. Then remove the
cover from the top of the receiver battery case.

❍ 6. Remove the receiver battery holder from the receiv er battery
case. Install 4 (included) "AA" batteries into the battery holder in
the configuration molded into the battery holder. Re-install the
battery holder and the battery case top with the two 3x10mm
screws which you removed earlier.

❍ 7. Remove the transmitter antenna from the parts bag and
install it into the top of the transmitter as shown. To ensure that
the antenna is attached, lightly pull on the antenna. If it slides out,
it is not screwed in properly.

❍ 8. Slide off the battery door on the bottom of the transmitter.
Install 8 "AA" batteries into the bottom of the transmitter in the
configuration molded into the battery holder . Re-install the battery
door onto the bottom of the transmitter.

❍ 9. Turn the transmitter on using the switch on the front. The red
LED light next to the on/off switch should light up. If the LED does
not light up, turn the transmitter off and check to make sure the
batteries are properly installed in the bottom of the transmitter.
Turn the transmitter on again to make sure the red LED lights, and
if it does turn the transmitter off. If the LED light is blinking, the

batteries are low and should be replaced!

❍ 10. Remove the clear lexan truck body from the box. Prepare
the lexan body to be painted by washing it out with warm water
and a liquid detergent. Dry the body off with a non-abrasive cloth.

Mask the windows off on the inside of the body with masking
tape. Paint the body using a polycarbonate or lexan compatible
paint. Remove the masking from the windows. Cut the excess
lexan around the molded cut lines, and remove the clear protec­tive cover from the outside of the body. Locate the dimples in the
body which mark the body post locations. Drill these dimples out
using a 5/16" drill bit or by using a lexan body reamer. Apply the
decals as shown on the front of the box. Install the body onto the
four body posts and install a body clip onto each post.

❍ 11. Refer to the separate instruction sheet for running and tun­ing your engine.

Before Each Run

• Check for loosened screws on the truck. Engine vibration will
loosen some of the screws, particularly in the engine mount
area. Use thread lock on screws that thread into metal parts or
use a metal nut.

• Inspect the air cleaner for a torn or damaged element. Also
look for dirt in the air cleaner element and wash or replace it
if necessary.

• Check the suspension and drive train for binding.

• Inspect all of the wires for damage. Also check the connectors
to make sure all of them are tight and in the proper place.

• Check the fuel tank and fuel lines for leaks.

• Before starting the engine, turn on the radio and make sure the
servos move easily and in the right direction.

• Before running, always check the condition of your radio sys­tem batteries and replace/recharge if necessary.

After Each Run

• Drain the fuel tank of any leftover fuel. DO NOT return it to
your fuel jug.

• Put some after-run oil in the carb and turn the flywheel several
times to work the oil into the engine. T his will protect the engine
from rusting, especially when stored for a long period of time.

• Check again for loosened screws.

• CLEAN the truck. Wipe off any oils that have collected on the
chassis, engine end exhaust. Oils will attract dirt on the next run.
