IMPORTANT NOTES – ELECTRICAL

• Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape) to prevent dangerous short circuits. Take maximum care in wiring, connecting and insulating
cables. Make sure cables are always connected securely. Check connectors for if they become loose. And if so, reconnect them securely. Never use R/C models with damaged
wires. A damaged wire is extremely dangerous, and can cause short-circuits resulting in fi re. Please have wires repaired at your local hobby shop.

• Low battery power will result in loss of control. Loss of control can occur due to a weak battery in either the transmitter or the receiver. Weak running battery may also result in
an out of control truck if your truck‘s receiver power is supplied by the running battery. Stop operation immediately if the truck starts to slow down.

• When not using RC model, always disconnect and remove battery.

• Do not disassemble battery or cut battery cables. If the running battery short-circuits, approximately 300W of electricity can be discharged, leading to fi re or burns. Never
disassemble battery or cut battery cables.

• Use a recommended charger for the receiver and transmitter batteries and follow the instructions correctly. Over-charging, incorrect charging, or using inferior chargers can
cause the batteries to become dangerously hot. Recharge battery when necessary. Continual recharging may damage battery and, in the worst case, could build up heat
leading to fi re. If battery becomes extremely hot during recharging, please ask your local hobby shop for check and/or repair and/or replacement.

• Regularly check the charger for potential hazards such as damage to the cable, plug, casing or other defects. Ensure that any damage is rectifi ed before using the charger
again. Modifying the charger may cause short-circuit or overcharging leading to a serious accident. Therefore do not modify the charger.

• Always unplug charger when recharging is fi nished.

• Do not recharge battery while battery is still warm. After use, battery retains heat. Wait until it cools down before charging.

• Do not allow any metal part to short circuit the receiver batteries or other electrical/electronic device on the model.

• Immediately stop running if your RC model gets wet as may cause short circuit.

• Please dispose of batteries responsibly. Never put batteries into fi re.

IMPORTANT NOTES – NITRO ENGINES

• Always test the brakes and the throttle before starting your engine to avoid losing control of the model.

• Make sure the air filter is clean and oiled.

• Never run your engine without an air filter. Your engine can be seriously damaged if dirt and debris get inside the engine.

• For proper engine break-in, please refer to the manual that came with the engine.

• Do not run near open flames or smoke while running your model or while handling fuel.

• Some parts will be hot after operation. Do not touch the exhaust or the engine until they have cooled. These parts may reach 275°F during operation!

IMPORTANT NOTES – NITRO FUEL

• Handle fuel only outdoors. Never handle nitro fuel indoors, or mix nitro fuel in a place where ventilation is bad.

• Only use nitro fuel for R/C models. Do not use gasoline or kerosene in R/C models as it may cause a fire or explosion, and ruin your engine.

• Nitro fuel is highly inflammable, explosive, and poisonous. Never use fuel indoors or in places with open fires and sources of heat.

• Always keep the fuel container cap tightly shut.

• Always read the warning label on the fuel container for safety information.

• Nitro-powered model engines emit poisonous vapors and gasses. These vapors irritate eyes and can be highly dangerous to your health. We recommend wearing rubber or vinyl gloves

to avoid direct contact with nitro fuel.

• Nitro fuel for RC model trucks is made of the combination of the methyl alcohol, castor or synthetic oil, nitro methane etc. The flammability and volatility of these elements is

very high, so be very careful during handling and storage of nitro fuel.

• Keep nitro fuel away from open flame, sources of heat, direct sunlight, high temperatures, or near batteries.

• Store fuel in a cool, dry, dark, well-ventilated place, away from heating devices, open flames, direct sunlight, or batteries. Keep nitro fuel away from children.

• Do not leave the fuel in the carburetor or fuel tank when the model is not in use. There is danger that the fuel may leak out.

• Wipe up any spilled fuel with a cloth

• Be aware of spilled or leaking fuel. Fuel leaks can cause fires or explosions.

• Do not dispose of fuel or empty fuel containers in a fire. There is danger of explosion.

FIRST AID

• Do not swallow nitro fuel or get it in your eyes. If this happens, immediate measures should be taken.

• If fuel is swallowed, immediately drink large quantities of water and induce vomiting. Consult a physician or poison control center immediately.

• If fuel gets into the eyes, rinse them well with water, and then consult a physician immediately.

• If fuel gets onto the skin, wash it with soap and water well.

THINGS TO KNOW ABOUT YOUR ENGINE

High-performance competition engines can sometimes fail; no guarantee for these types of failures exist, and we are not responsible for the use and treatment of an engine. These
engines can make extremely high RPMs and build up incredible loads inside. It is extremely important that you check frequently for excess play in any components (especially the
conrod/big-end) and also engine compression. Most failures occur because of low-quality fuel or mixtures, bad carburetor settings, bad functioning of the air filter, or excessive
wear of moving parts. Please take note that it is suggested not to modify any parts of the engine.
If you want to repair the engine yourself, take care of the following:

• Clean the outside of the engine thoroughly before you open it, work on a clean spot, use proper tools. Any dust or dirt that enters the engine will make considerable damage.

• All moving parts inside the engine are subject to wear. If a piston/liner has worn out, or if the big-end/conrod connection has worn, you must replace these parts. If the engine has

broken you must check that all other moving parts are still in good shape. If you only change one part and other parts are not in good shape, it is highly likely that your engine will
suffer another failure shortly thereafter.

• If you want to replace the conrod, be sure the big-end of your crankshaft is still round and at a good size, if not replace the crankshaft. If you do not replace the crankshaft and

re-use the engine, a failure may occur such as conrod or piston breakage.

• If you replace the piston and liner, be sure to check the big-end on the crankshaft.

• These high-technology engines need to be treated with precision. If you are not sure how to modify or repair your engine, ask your local dealer to do it for you or return the engine

to us.

SERVICING THE ENGINE

Should your engine require service, please follow the following guidelines. Do not return the engine to the place of purchase, as they are not authorized or equipped to perform
service.

1. Remove the engine from the model. We cannot accept equipment for service other than the engine.

2. Along with your engine and proof of purchase, enclose a complete written explanation of the problem(s) with as much detail as possible.

3. Be sure to include your complete and proper name, address, and daytime telephone number(s).

The charges for repairs will be billed to you C.O.D. Please mention if you wish to have an estimation of repair charges prior to us beginning service. (This may cause a slight delay
in your repair.) Contact your national distributor who will advise you how to proceed.

CHARGING BATTERIES

Before operating your micro nitro truck for the fi rst time, you need to properly charge the receiver battery pack and the starterbox battery pack.

USE THE PROPER BATTERY CHARGER

We strongly recommend using a high-quality peak-detection charger with automatic shut-off. The charger should be specifi cally designed for charging NiMH batteries used
in the receiver pack and starterbox battery pack. Charge each pack at its recommended rate, and do not overcharge or damage or injury may result. Carefully follow the
manufacturer’s instructions that accompany the battery charger.

INITIAL CHARGING & CYCLING THE BATTERY PACKS

The receiver battery pack and starterbox battery pack must be cycled before fi rst-time use. When cycling the receiver battery pack for the fi rst time, carefully follow these instructions:

1. Set the charge current to 110 mA (0.11A).

2. Charge each battery pack for 14-16 hours. During charging it may happen that the charger will stop charging while the battery pack is not fully charged. In such case you
can continue charging until the battery pack is fully charged. This may happen one or more times during charging and this issue is related to the type of charger or type of
charging used.

3. After 14-16 hours disconnect the battery pack, even if the charger is still charging it.

4. Let the battery pack rest for 1 day.

5. After 1 day discharge the battery pack. Set the discharger to a 1.1A discharge rate, and set the discharge cut-off voltage to 4.5V for the pack (0.9V per cell).

6. Let the battery pack rest for 6 hours.

Your battery packs have now been cycled and you can use them safely.

RAPID CHARGING

After you have initially charged and run the receiver and starterbox battery packs, you can rapid charge the packs afterwards.

Using a peak-detection charger, set each battery pack to charge at the proper rate (1.0A for receiver pack, X.XA for starterbox battery pack). Do not use higher charge currents;

rapid charging is done at a higher current, so the battery pack may generate too much heat and explode or vent. Never leave the battery pack unattended while it is charging. If
the battery pack becomes too hot (113°F or higher), stop charging immediately.

DISCHARGING AND STORAGE

After use, we DO NOT RECOMMEND discharging the packs completely, as this will damage the packs. You can safely recharge the packs immediately after use without any

performance degradation. If you will be storing the packs for longer than a month, partially discharge the pack down to approximately 40% capacity.

7

IMPORTANT WARNINGS

A new, unused battery pack is guaranteed against manufacturer‘s defects and workmanship. Any damage due to misuse by the user will be repaired at the user‘s expense.
There is no warranty expressed or implied that covers damage caused by normal use, or covers or implies how long the battery pack will run (run time), or last before requiring
replacement due to normal use and normal cell degradation. XRAY shall not be liable for any damage caused by overcharging, battery failure, improper charging or discharging,

use of non-approved chargers, use of non-approved batteries, and alternations or modifi cations of any kind to the charger, batteries, switches, or wiring.

WARRANTY

INSTALLING THE ANTENNA

You must install the antenna tube before operating your micro nitro truck.

• Never disassemble the battery pack or peel away the cover.

• Keep the battery pack away from water.

• Do not touch the battery pack with wet hands or wet objects.

• Do not subject the battery pack to strong impacts and short circuits.

• Keep the battery pack away from fi re and fl ammable objects.

• Disconnect the battery pack when it is not in use.

• Do not put metal objects in the battery pack connector or touch the terminals

• in the connector.

• Do not throw away the battery pack when you no longer need it. Bring it to the shop from which you bought it, or to a shop offering battery recycling service.

• If leaked battery alkaline electrolyte gets in your eyes or on your skin, fl ush thoroughly with clean water and consult with a doctor immediately.

• Regularly check the wiring for damage. While running the truck, vibration or movement may cause damage to the wires which if left unchecked may result in a short circuit. If
any wire insulations becomes damaged, please dispose of the battery pack properly and do not use it, nor try to repair it.

• You are responsible for the proper use of this battery pack and any damage that may occur due to its use or misuse. XRAY is not liable for any injury, damage, or harm caused
to any person or property arising from the use or misuse of their products.

1. Locate the black antenna wire that exits the receiver. The receiver

is mounted on the top of the servo.

2. Pull the wire straight with your fi ngers and then insert the end of

the wire into one end of the antenna tube. Push the wire all the
way through the antenna tube.

3. Pull the remaining wire through the antenna tube, and then

insert the base of the antenna tube into the molded post on the
chassis to which the servo is mounted.

4. Fold the remaining antenna wire over the top of the tube. The

remaining wire can stick up.

TIP:

Spray a small amount of window cleaner on the antenna wire to
make it easier to push through the antenna tube.
Do not push the transmitter antenna down from the top. Pull it down
from the bottom, one segment at a time, to prevent binding and
kinking the antenna mast.

CAUTION !!!

Do not shorten the length of the antenna wire. Its length is tuned to the frequency band; cutting it may severely shorten the radio system’s range.

DECORATING THE BODY

The micro nitro truck body was hand-painted with premium-quality, high-gloss paint and several stickers were applied to the body.

If you want to use the included rear wing, you must trim it fi rst. When installing the wing on the Monster Truck make two holes in the rear of the body as indicated. Attach the rear
wing to the body using the included screws and plastic nuts. To install the wing to the truck use a double-sided tape.
Extra decals are provided to decorate and personalize your micro nitro truck body.
Use the tip of a hobby knife to lift the corner of a decal, then remove it from the backing sheet.

Position the decal over the desired location on the body, and press it onto the body. Pull tight on the decal if required, and use your fi ngers to smooth out any air bubbles.

INSTALLING THE TRANSMITTER BATTERIES

Your XT1 Transmitter uses eight AA batteries. The battery tray is located at the base of the transmitter.

1. Remove the battery cover (bottom of transmitter) and remove the battery tray.

2. Install eight (8) AA alkaline batteries into the battery holder. Pay close attention to the correct direction of the positive (+) and negative (-) ends of the

batteries as marked in the tray.

3. Reinstall the battery tray using the molded pegs in the bottom as a guide, then replace the battery cover.

4. Turn on the transmitter and check that the LED power indicator gives a solid red light.

If the power indicator does not light up, the transmitter batteries may be weak, discharged, or possibly installed incorrectly. Check the battery positions fi rst, then replace any weak
batteries with new or freshly-charged batteries as required.

The power indicator light does not indicate the charge level of the main battery pack in the truck.

Use only fresh alkaline or rechargeable batteries, all of the same brand. Make sure that rechargeable batteries are fully charged according to the manufacturer’s instructions. If
you use rechargeable batteries in your transmitter, be aware that when they begin to lose their charge, they lose power much more quickly than regular alkaline batteries.
