• Occasional maintenance work and repairs are required to ensure safe use. For example, the tyres may become worn, or some parts may be damaged due to driver error. Only use genuine spare parts for maintenance and repair work.

b) Setup

• The instructions for the remote control system and charger are included separately. Always follow all the safety information as well as all other information! Numerous hazards are associated with improper handling of the battery charger.
• Never wind the aerial cable! This significantly reduces the transmission range. Take care not to damage the antenna cable. Never attempt to shorten the cable!
• Only use suitable drive batteries for the vehicle. Never power the speed controller with a power adapter, even for test purposes.
• This vehicle is only suitable for use with a 6-cell NiMH battery (nominal voltage 7.2 V) or a 2-cell LiPo battery (nominal voltage 7.4 V).

Using a drive battery with more cells may make the speed controller overheat and cause a fire. In addition, the powertrain may be damaged due to overload (e.g. differential), which will void the warranty/ guarantee!
Warning!
The NiMH battery charger should only be used to charge a NiMH vehicle battery. Attempting to charge a LiPo battery with the NiMH battery charger may cause a fire or explosion! A LiPo battery can only be charged with a compatible LiPo battery charger (similarly, NiMH batteriesmust be charged with a NiMH charger). If you wish to purchase a LiPo battery for the vehicle, you willalso need to purchase a suitable LiPo battery charger.
Always ensure that you use the correct type of battery charger.
Always switch on the remote control before connecting the vehicle battery and switching on the speed controller, otherwise the vehicle may react unexpectedly!
Proceed as follows:
– Before connecting the battery, place the vehicle on a suitable surface so that all wheels can move freely.
– Switch off the speed controller.
– Switch on the remote control and check that it functions correctly (e.g. the display turns on).
– On the remote control, set the trim for the throttle/brake function to the central position.
– Connect a fully-charged vehicle battery to the speed controller in the correct polarity.
– Turn on the speed controller. Wait for a few seconds until the speed controller has completed a self-test.
– Check that the vehicle reacts to the remote control commands as expected (steering and throttle) before removing it from the support and placing the wheels on the ground.

c) Driving the vehicle

• Improper use can cause serious injury and damage to property! Only use the vehicle when it is within your sight. Do not use the vehicle at night.
• Only use the vehicle when you are fully alert and able to respond. As is the case when driving a real vehicle, fatigue, alcohol or medications can affect your ability to respond.
• This model vehicle must not be used on public roads, spaces or paths. Do not use the vehicle on private land without the landowner’s permission.
• Do not drive towards people or animals!
• Avoid driving in very low outdoor temperatures. Plastic parts lose their elasticity in cold temperatures. This can result in serious damage even after a minor accident.
• Do not use the vehicle during thunderstorms, under high-voltage power lines or next to radio masts.
• Always leave the remote control turned on when the vehicle is in use.
• When you have finished using the vehicle, switch off the speed controller and fully disconnect the battery from the speed controller. You can now switch off the remote control.
• The range of the remote control decreases when the batteries are nearly empty. Replace the batteries when necessary.

When the vehicle battery is nearly empty, the vehicle will slow down and may not respond properly to the remote control. In addition to powering the motor via the speed controller, the vehicle battery also generates the necessary voltage/current for the receiver and the steering servo. This voltage is generated via an integrated BEC (“Battery eliminator circuit”, an electronic circuit that supplies a voltage directly to the receiver without an additional receiver battery). If the battery voltage is too low, the receiver voltage may drop and the vehicle may not respond to remote control commands.
If this occurs, stop driving the vehicle immediately (switch off the speed controller, disconnect the battery from the vehicle and switch off the remote control). Replace/recharge the vehicle battery as necessary.

• The engine, drive, speed controller and vehicle battery heat up during use. Pause for at least 5–10 minutes before changing the battery.
• Allow the vehicle battery to cool down completely before charging.
• Do not touch the motor, speed controller or rechargeable battery until they have cooled down. Burn hazard!
• Improper use can cause serious injury and damage to property! Only use the vehicle when it is within your sight. Do not use the vehicle at night.

Battery safety information

Batteries present numerous safety hazards. Compared with conventional NiMH rechargeable batteries, LiPo rechargeable batteries have a high energy content. For this reason, it is essential to comply with safety regulations to prevent the risk of a fire or explosion.
Always observe the following safety information when handling batteries:

• Keep batteries out of the reach of children.
• Do not leave batteries lying around, as they present a choking hazard for children and pets. Seek immediate medical advice if a battery is swallowed.
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into fire, as thismay cause an explosion!
• If you do not plan to use the model for an extended period (e.g. during storage), remove the batteriesfrom the remote control to prevent them from leaking and causing damage. Disconnect the vehicle battery and remove it from the vehicle.
• When handling leaking or damaged batteries, always use suitable protective gloves to avoid burningyour skin.
• Liquids leaking from batteries are very chemically aggressive. Objects or surfaces coming into contact with these liquids could be severely damaged. Always store batteries in a suitable location that is not prone to damage.
• Do not attempt to recharge disposable, non-rechargeable batteries. This may cause a fire or explosion!Only recharge compatible rechargeable batteries and ensure that you use a suitable battery charger.
• Always ensure that the batteries/vehicle battery are inserted in the correct polarity (observe the plus/+and minus/- symbols).
• Never mix disposable batteries with rechargeable batteries. The remote control can be powered withdisposable or rechargeable batteries.
• Always exchange the entire set of batteries in the remote control. Do not mix full batteries with half-full ones. Always use batteries of the same type and from the same manufacturer.
• The type of charger you require may vary depending on the type of rechargeable battery (NiMH,LiPo….). For example, you should never charge LiPo batteries with a NiMH battery charger. This maycause a fire or explosion!
• A balancer is required to charge multi-cell LiPo batteries (most LiPo chargers features a built-in balancer). A balancer monitors the voltage of each LiPo cell to prevent individual cells from overcharging. Overcharging a LiPo battery cell (max. cell voltage 4.24 V) can cause the battery to expand or evenresult in a fire or explosion.
• Only charge intact and undamaged batteries. Do not charge batteries if the external insulation or batteryhousing is damaged, or if the battery is deformed or swollen. This may cause a fire or explosion!
• Never charge batteries immediately after use. Always allow them to cool down for at least 5–10 minutes.
• Always remove the battery from the vehicle before charging it.
• Place the charger and battery on a heat-resistant, non-combustible surface.
• The charger and battery will heat up during the charging process. Ensure that there is a sufficient distance between the charger and battery. Never place the battery directly onto the charger. Never cover the charger and the battery. Do not expose the charger or battery to extremely high/low temperatures or direct sunlight.
• Never leave batteries unattended when they are charging.
• Rechargeable batteries should be charged regularly (approx. once every 2 – 3 months) to prevent them from overdischarging. This may result in permanent damage and render the batteries useless. NiMH rechargeable batteries (except special batteries with a low self-discharge) lose their charge within a few weeks. LiPo batteries usually retain their charge for several months. However, if the batteries overdischarge, this will result in permanent damage and render them useless.
• Never use an excessive charging current. Observe the manufacturer’s specifications for the ideal/maximum charging current.
• Disconnect the battery from the charger when the battery is fully charged.
• The charger and the rechargeable battery must not get damp or wet. This may result in a fatal electric shock or cause a fire or explosion! Lithium rechargeable batteries (e.g. LiPo batteries) contain chemicals that are very sensitive to moisture.

Charging the vehicle battery

• The vehicle comes with a 6-cell NiMh rechargeable battery and a NiMH battery charger. Refer to the charger instructions before charging the battery.

Warning!
The NiMH battery charger should only be used to charge a NiMH vehicle battery. Attempting to charge a LiPo battery with the NiMH battery charger may cause a fire or explosion! A LiPo battery can only be charged with a compatible LiPo battery charger (similarly, NiMH batteries must be charged with a NiMH charger). If you wish to purchase a LiPo battery for the vehicle, you will also need to purchase a suitable LiPo battery charger.

• The vehicle battery is empty when the product is shipped and must be charged. Several complete discharge and charge cycles are required to ensure that the battery reaches it maximum performance. NiMH and LiPo batteries can be recharged when they are partially discharged. They do not normally need to be fully discharged in advance.
• High-quality vehicle batteries have a higher capacity, which results in a longer battery life. They also have a higher output voltage, which provides more power for the motor for enhanced acceleration and higher speeds.
• The vehicle battery heats up when charging/discharging (i.e. when driving the vehicle). Wait until the battery has reached room temperature before charging it. The same applies after the battery has finished charging. Allow the battery to cool down before connecting it to the vehicle
• Only use a charger that is designed for the type of vehicle battery used (e.g. NiMH or LiPo).
• Always remove the battery from the vehicle before recharging it.

Setup

a) Removing the chassis

Remove the clips and lift the chassis off the vehicle:
b) Configuring the speed controller The speed controller features two jumpers that can beused to configure the driving functions and the rechargeable battery. “MODE” jumper (A): Use this jumper to select the operating mode. Leave the jumper in the “Mode 1” setting. “BATT” jumper (B): Use this jumper to select which typeof battery is connected to the speed controller (LiPo orNiMH).
Important! If you are using a LiPo vehicle battery and set the battery type to NiMH, the battery will overdischarge and be permanently damaged. Always ensure that you select the correct battery type before driving the vehicle. The “LiPo” setting reduces the motor power by 50 % when the battery voltage drops below 6.5 V. The speed controller switches the motor off when the battery voltage drops below 6.0 V. This prevents the LiPo battery from overdischarging, which damages the battery. The “NiMH” setting reduces the motor power when the battery voltage drops below 4.5 V. The motor is switched off when the battery voltage drops below 4.0 V.
c) Inserting batteries into the remote control
Open the battery compartment on the remote control and insert new or fully charged batteries. Ensure that the batteries are inserted in the correct polarity (observe the positive/+ and negative/- markings). Replace the battery compartment cover. Read the remote control instructions included with the product.
d) Configuring the remote control
Switch on the remote control and set the steering and throttle trim to the central position. If the remote control has a dual rate feature, disable it or adjust it so that the   teering angle is not limited. Read the remote control instructions included with the product.
e) Inserting the vehicle battery

Warning! Switch on and configure the remote control before connecting the vehicle battery to the speed controller (see sections 9. c) and 9. d). Important! This vehicle is only suitable for use with a 6-cell NiMH battery (nominal voltage 7.2 V) or a 2-cell LiPo battery (nominal voltage 7.4 V). Using a drive battery with more cells may make the speed controller overheat and cause a fire. In addition, the powertrain may be damaged due to overload (e.g. differential), which will void the warranty/guarantee! Check whether the battery has a suitable connector system for the speed controller and that the polarity is correct (red cable = positive/+, black cable = negative/-).
Loosen the strap (A) on the battery holder.
Insert the vehicle battery into the battery holder (B).
If the battery connection cable is very short, the battery must be inserted into the battery holder so that the connection cable points towards the rear of the vehicle. Pull  the  trap (A) tight so that the vehicle battery is securely in place, and then secure the strap.
f) Connecting the vehicle battery to the speed controller

Place the vehicle on a suitable support (or a start box) so that the wheels can move freely. This ensures that you will not lose control of the vehicle if the wheels move suddenly (e.g. if the throttle trim is not set correctly). Do not reach into the engine or hold the wheels in place.
Switch off the speed controller (move the switch to the “OFF” position). The on/off switch can be found directly next to the speed controller (refer to the labels on the switch). If you have not already done so, switch on the remote control (see sections 9. c) and 9. d). Connect the vehicle battery to the speed controller. Ensure that the battery is inserted in the correct polarity (red cable = positive/+, black cable = negative/-). Do not use force when connect the battery plug to the speed controller.
Important! This vehicle is only suitable for use with a 6-cell NiMH battery (nominal voltage 7.2 V) or a 2-cell LiPo battery (nominal voltage 7.4 V). Make sure that the cable cannot get into the vehicle’s drive components or the steering mechanism. If necessary, use cable ties to fix the cables in place.
g) Switching on the speed controller
Switch on the speed controller by moving the sliding switch (see i mage in section 9. f) to the “ON” position. Wait for a few seconds (leave the throttle/brake lever in the neutral position) until the speed controller has completed a test.
→  If the speed controller does not detect a signal from the remote control or does not detect that the throttle lever is in the neutral position, the red LED indicator will continue to flash and you will not be able to use the speed controller.

• 1x short tone: NiMH vehicle battery detected
• 2x short tones: 2-cell LiPo battery detected
• 1x long tone: Test was successfully completed; thethrottle/brake lever is in the neutral position and thespeed controller is ready for use.| • LED off: Throttle/brake lever on the remote control is in the neutral position
• LED flashes: Throttle/brake lever on the remote control is in theforwards/backwards position
• LED on: Maximum throttle

→  The acoustic signals are generated by the motor.
Check that the throttle and steering functions are working correctly.
h) Attaching and securing the chassis
Place the chassis onto the fixtures and fix it in place it with the clips.
i) Attaching the decorative accessories to the chassis
The accessories can be attached to the chassis for decorative purposes. You can use hot glue or plastic adhesives  to secure the accessories in place.
j) Controlling the vehicle
Place the vehicle on the ground. Do not reach into the engine or hold the wheels.
Move the throttle/brake lever on the remote control very carefully and drive slowly until you are familiar with how the vehicle responds to the remote control. Do not make sudden adjustments to the remote control  levers.
If the vehicle shows a tendency to move to one side, adjust the steering trim on the remote control accordingly.
→ The following images are for reference purposes only and do not necessarily correspond to the design of  the remote control included with the product!

1. Release the throttle/brake lever (move it to the neutral position). The vehicle should roll to a halt or stay stationary (if necessary, adjust the throttle trim on the remote control).

2. Slowly pull the throttle/brake lever towards the handle to make the vehicle move forwards.

3. Slowly push the throttle/brake lever away from the handle to make the vehicle move backwards. Do not switch immediately between forwards/reverse. Bring the vehicle to a standstill first before moving it in the other direction. Directly switching to another direction may overload the drive components.

Stop driving immediately if the vehicle does not respond correctly to remote control commands. If this occurs, the vehicle/remote control batteries may be nearly empty, or the vehicle may be too far from the remote control. A damaged receiver antenna, interference on the wireless channel (e.g. from other devices, Bluetooth ® or Wi-Fi) or poor reception/transmission conditions may cause the vehicle to respond incorrectly. The receiver is powered by the speed controller/vehicle battery, therefore the vehicle may not move correctly when the vehicle battery is nearly empty (e.g. the steering servo may not work properly).
For example, the vehicle battery voltage may drop momentarily at full throttle, and the receiver may not receive the required voltage as a result. If this occurs, the vehicle will accelerate, but the steering servo will not respond correctly. Discontinue use immediately and use a new, fully charged vehicle battery.
If the vehicle battery is empty, wait for at least 5 – 10 minutes until the engine and speed controller have cooled down. You can then use the vehicle again with a fully charged battery.
k) Turning the LEDs on/off
The front and rear bumpers are equipped with LEDs. These can be switched on and off using a small sliding switch (see arrow in right-hand image).

I) Stopping the vehicle To stop the vehicle, proceed as follows:

• Release the throttle/brake lever on the remote control so that it is in the neutral position, and then let the vehicle coast to a standstill.

• Wait until the vehicle has stopped, and then switch off the speed controller (move the switch to the “OFF” position). Do not reach into the wheels or drive components or move the throttle/brake lever on the remote control. Do not hold the vehicle by the wheels!
  Warning! The motor, speed controller and drive battery become very hot during use! Do not touch these parts immediately after use – burn hazard!

• Disconnect the vehicle battery from the speed controller. Unscrew the plug-in connection completely.

• You can now switch off the remote control.

Cleaning and maintenance

a) General
Before cleaning or maintenance, the speed controller must be turned off and the vehicle battery must be completely disconnected from the speed controller. Allow all parts to cool down completely (e.g. engine and speed controller).
After you have finished using the vehicle, remove all dust and dirt (e.g. using a clean long-haired brush and a vacuum cleaner). Compressed air aerosols can also help to remove dirt.
Do not use cleaning sprays or conventional household cleaning chemicals. These may damage the electronic components and discolour the plastic parts or chassis. Never wash the vehicle with water (e.g. with a high-pressure cleaner), as this may destroy the engine, speed controller or receiver.
Use a soft, slightly damp cloth to wipe the chassis. Do not rub too firmly, as this may result in scratch marks.
b) Before and after each use
Engine vibrations and impacts during driving may cause certain parts and screw fittings to become loose. Check the following before and after each use:

• All wheel nuts and screw fittings must be secure
• Check that the speed controller, on/off switch and receiver are secure
•  Check the condition of the tyres and ensure that they adhere to the wheel rims
• Check that all cables are attached (they must not touch the moving parts of the vehicle)
  →  Check the vehicle for any signs of damage before and after each use. If there are any signs of damage  discontinue use immediately. Only use genuine spare parts when replacing worn vehicle parts (e.g. tyres) or defective vehicle parts (e.g.a broken suspension arm).
  c) Changing a tyre The tyres are fixed on the wheel rim and cannot be removed. If a tyre is worn, the entire wheel must be replaced.
  After removing the nut cover (A), loosen the wheel nut (B) with a suitable spanner, and then pull the wheel off thewheel axle (D). Attach the new wheel so that the hex socket on the insideof the wheel rim fits exactly over the wheel hub nut (C). Screw the wheel onto the axis using the wheel nut (B) thatyou previously removed. Do not use any force, otherwisethe wheel will not spin freely and the drive componentsmay be damaged. Insert the nut cover (A) onto the wheel nut (B).

→ When you remove the rear wheel, the wheel hub nut (C) may get stuck in the wheel rim or become detached from the wheel axis (D). Ensure that the drive pin (E) does not fall off.   If the wheel is subsequently re-fitted, it is important to check that the drive pin (E) is inserted exactly into the centre of the wheel axle (D) and that it is positioned in   he corresponding notch on the wheel hub nut (C).  If the drive pin (E) is missing, no torque can be transferred from the motor to the wheel and the wheel will spin freely.
d) Adjusting the backlash

The backlash is preset to an optimal setting and does not normally need to be corrected. However, vibrations may cause the screws in the motor to become loose after  prolonged use. If this occurs, the screws must be tightened and you must check that the  backlash is correct.Remove the dust cover (A) by unscrewing the 3 screws.

The distance between the main gear (B) and the engine pinion (C) should be as small as possible whilst ensuringthat the gears are not too tight. Loosen the screws (D) on the motor slightly, and then gen- tly slide the engine with the engine pinion (B) towards the main gear (C).
→  The engine must not shake; the screws should only be loosened enough to allow the engine to move. The engine pinion and the main gear should now grip eachother with no backlash. However, this is detrimental to the lifespan of the gears.

Place a strip of thin paper (E) between the main gear (C)and the engine pinion (B). Turn the main gear so that thepaper strip (max. 80 g!) is pulled between the two gears. The pressure of the paper pushes the electric motor by therequired amount. Tighten the screws (D) on the motor. When you turn the main gear in the other direction to remove the strip of paper (G), both gears should be at thecorrect distance to one another. Replace the dust cover and screw it in place.
→ Ideally, the engine pinion should be as close as possible to the main gear whilst ensuring that the cogs do not touch, as this makes the gears too tight.
If the gears (engine pinion and main gear) are too far apart, the cogs on the main gear will be damaged by the engine pinion after just a few seconds, which will void the warranty/guarantee!
However, if the engine pinion presses against the main gear (i.e. there is no clearance between the cogs), this will decrease performance, increase power consumption (the motor requires lots of power to turn the main gear) and lead to premature wear.
e) Adjusting the friction clutch
The friction clutch protects the gears against overload (e.g. on non-slip surfaces). In addition, adjusting the friction clutch correctly prevents the vehicle from overturning due to the motor’s high torque. The manufacturer has configured the optimal setting, therefore you do not normally need to make any changes.
Driving frequently at full speed on a non-slip surfaces may wear down the surface of the friction clutch. If this occurs, you may need to recalibrate the clutch. Professional drivers can adjust the friction clutch to make the vehicle respond differently on a particular surface.
To adjust the clutch, proceed as follows: Remove the dust cover (A) by unscrewing the 3 screws. The friction clutch can be adjusted by turning the hex nut (B). Turn the hex nut clockwise to increase the drive power to the gearbox, or anticlockwise to decrease the power transmission.

If the friction clutch is too tight, the maximum drive power will be transmitted and the clutch will not function. This may damage the differential and the vehicle may overturn on non-slip surfaces due to the high torque from the motor. If the friction clutch is too “soft”, this places significant wear on the friction clutch. It also affects acceleration and may prevent the vehicle from moving (due to spinning of the friction clutch).
→  Adjust the clutch in small steps (max. 1/4 turn) and check how the vehicle responds. Make a note of each change so that you can revert to the previous setting if necessary.

Troubleshooting

This model was built using the latest technology. However, faults and malfunction may still occur. The following section shows you how to troubleshoot potential faults. Ensure that you also read the remote control instructions included with the product.
The model does not respond or does not respond correctly:

• In the case of 2.4 GHz remote control systems, the receiver must be connected to the remote control. This process is known as “pairing”. The manufacturer pairs the remote control with the receiver before the vehicle is shipped. However, you can also pair the remote control yourself. To do this, follow the enclosed operating instructions for the remote control.
• Is the vehicle battery or the remote control batteries empty? If so, replace the vehicle battery or remote control batteries.
• Did you switch on the remote control before switching on the speed controller? For safety reasons, the speed controller does not function if this is done in the reverse order.
• Is the vehicle battery connected to the speed controller? Check the connection to see if it is dirty or rusted.
• Is the vehicle too far away? The range should be at least 50 m when the vehicle battery and the remote control batteries are full. However, this can be reduced by the ambient conditions, such as interference on the transmission frequency or proximity to other transmitters (including Wi-Fi/Bluetooth ® devices that use a transmission frequency of 2.4 GHz), metal objects and buildings. The position of the remote control and receiver aerials relative to one other also has a significant impact on the range. For best results, the remote control and receiver aerial should be vertical (i.e. parallel to each other). Pointing the remote control aerial at the vehicle significantly reduces the range.
• Check the correct position of the speed controller plug and steering servo on the receiver. If the plugs have been rotated 180°, the speed controller and steering servo will not work. If the connectors for the speed controller and steering servo are connected the wrong way round, the throttle/brake servo will control the steering servo (and vice versa).

The vehicle doesn’t stop when the throttle/brake lever is released

• Correct the throttle trim on the remote control (set the neutral position).

The vehicle travels slowly or the steering servo does not respond properly to remote control commands; the range between the remote control and the vehicle is very short

• The vehicle battery is nearly empty.
  The receiver and the steering servo are powered by the BEC in the speed controller. As a result, the receiver will not function properly when the battery is nearly empty. Replace the vehicle battery with a fully charged battery (before changing the battery, wait for at least 5 – 10 minutes for the motor and speed controller to cool down).

• Check the batteries in the remote control.

The vehicle slows down or comes to a standstill while being driven

• The vehicle battery is nearly empty.
• The speed controller overheated and overtemperature protection was enabled (indicated by a flashing red LED).Leave the speed controller to cool down before using it again.
• The vehicle is too far from the remote control and the speed controller did not detect a signal via the receiver (or the receiver’s fail-safe function was activated, see remote control instructions).

The vehicle does not travel in a straight line

• Set the steering trim on the remote control.
• Check the steering linkage, the servo arm and the screw connection.
• Has the vehicle had an accident? If so, check the vehicle for any defective or broken parts and replace them if necessary. The vehicle moves in the opposite direction to the steering wheel on the remote control
• Enable the steering reverse function on the remote control.

The vehicle responds in the opposite way to the throttle/brake lever on the remote control

• Usually, the vehicle should move forwards when the throttle/brake lever on the remote control is pulled towardsthe handle.

If this is not the case, enable the reverse throttle on the remote control.

• Was the motor disconnected from the speed controller (e.g. when the vehicle was repaired)? If so, swap the motor cables.

The vehicle does not steer properly or the steering angle is too low

• If the transmitter has a dual rate setting, check that it is working correctly (refer to the remote control operating instructions for details). If the dual rate setting is too low, the steering servo will not respond.
• Check the steering mechanism for loose parts (e.g. check whether the servo arm is attached correctly to the servo).
