BEFORE EACH RUN
1. IMPORTANT: Check to make sure
that all screws are tight. Pay
particular attention to the screw pins
in the drive cups. Always use
threadlock (DTXR2010) on screws
going into metal.
2. Before running always check the condition of your radio
system batteries and replace/recharge if necessary.
3. Check to make sure that all of the moving parts of the
Warhead move freely and do not bind.
4. Check the fuel tank and fuel lines for leaks.
5. Before starting the engine, turn on the radio and make
sure the servos move easily and in the proper direction.
6. Inspect the air filter for a torn or damaged element. Also look
for dirt in the air cleaner element and wash it if necessary.
7. Check for broken or damaged parts. Replace any broken
or damaged parts before running the Warhead. Running
of the Warhead with broken or damaged parts could
result in damage to other parts.
8. Check to make sure that all wires are properly connected.
AFTER EACH RUN
1. Clean any large globs of dirt or debris from the chassis
and moving parts.
2. Drain the fuel tank of any leftover fuel. DO NOT return the
fuel to your fuel jug.
3. Check for any broken or damaged parts. This way parts
may be replaced before the next run.
4. Put some after-run oil in the carburetor and cylinder and
turn the flywheel several times to work the oil into the
engine. This will protect the engine from rusting, especially
when stored for a long period of time.
AFTER EVERY 10 RUNS
1. Check to make sure that the bearings are free of dirt and
debris, and roll smoothly.
2. Check the shocks for oil leakage. If the shocks have
leaked any shock fluid out, you should properly refill the
shocks for best performance.
3. Make sure the servo saver is free moving and does not bind.
This will help prevent stripping of the servo during running.
4. Check for proper gear mesh between the spur and clutch bell.
When tuning the Warhead make sure that you have equal
lengths from one side to the other on the shocks, camber
rods and steering rods. Also, make sure to have the shock
pre-load adjusters at the same setting from left to right. They
do not have to be the same front to rear.
2-SPEED ADJUSTMENT
• Once the engine is fully broken-in, the truck should shift
within 30-40 feet.
• There are a few things to remember when adjusting the
two speed: During break-in the truck may not shift into
second gear. This is normal. DO NOT adjust the two speed
until after the engine is fully broken-in. Also, do not adjust
the engine needles on the engine so the two speed shifts.
Adjust the engine to its best tune first, and then adjust the
two speed. Always make small adjustments.
• There are two set screws, the adjustment set screw is the
one that is at an angle. The other set screw is the one that
holds the shift hub to the reverser input shaft and is a
different size.
• To locate the adjustment screw, remove the rubber plug
and look into the access hole. Rotate the spur gear until
you see the aluminum shift hub. Hold the spur and roll the
truck until the correct (smaller) set screw comes into view.
• Use a 1.5mm hex wrench to adjust the two speed set screw:
To make the Warhead shift sooner, adjust the set screw
1/8th of a turn counter clockwise (looser).
To make the Warhead shift later, adjust the set screw
1/8th of a turn clockwise (tighter).
• Replace the rubber plug to keep dirt out of the transmission.
