After any fall it is always necessary to completely revise the condition of the vehicle. To be completely sure visit any Drill dealer.
3.2. Battery and charger, electrical components
3.2.1. Basic instructions
The battery is provided with a safety seal, the battery can only be opened by a Drill dealer. If this seal is damaged, you will lose your warranty.
Fully charge the battery before the rst use. The battery is equipped with BMS, which constantly evaluates the current status of the battery and
optimizes its performance. If the battery charge falls below 25% while driving, the control unit automatically reduces engine power. The system
is deactivated before the battery is completely discharged. Battery life may vary depending on the conditions in which the machine drives and
the riding style.

12
3. Operation
3.2.2. Battery charging
1/ Connect the charger to a 220V power supply.
2/ LED No. 1 on the charger lights up red to indicate that it is energized.
3/ LED No. 2 lights up green until the motorcycle charging connector is connected.
4/ Remove the protection cap on the motorcycle charging connector.
5/ Switch the main battery switch on the handlebars of the motorcycle to the ON position and disconnect the tug.
6/ Connect the charging connectors between the charger and the motorcycle.
7/ LED No. 2 on the charger turns red and the charger activates and starts charging the battery.
8/ The charger fan is active during charging and cools the charger.
9/ As soon as the battery is charged, the charger automatically switches o the cooling and LED No. 2 lights up. The LED is green when the
battery is charged.
10/ Turn the main battery switch to OFF.
11/ Disconnect the connectors between the motorcycle and the charger and attach the protective cap to the charging connector on the
motorcycle.
12/ Charging a fully discharged battery takes about 4 hours.
13/ Start the motorcycle according to the chapter "Starting the motorcycle and changing the driving mode".
3.2.3. Battery capacity indicator
The motorcycle is equipped with a central display, which shows the current state of charge of the battery in volts and at the same time via the
graphic symbol of the battery with 4 cells. To determine the battery capacity more accurately, it is better to monitor the voltage in volts. When
the battery is fully charged, the display shows 53, 7 V. If the voltage drops below 42 V, the motorcycle's control system begins to reduce power.
When the 39 V voltage is reached, the control system switches o the entire motorcycle to protect the battery. Further start-up of the motorcy-
cle after full discharge is only possible after recharging.

313
3. Operation
3.3. Starting and changing the driving mode
1/ Turn the main battery switch to ON.
2/ Attach the “tug”(put magnetic protection switch on wrist). The driving mode control indicator illuminates white and the motorcycle
acoustically signals readiness to drive.
3/ Carefully turn the gas handle. The motorcycle does not start and does not react to the gas.
4/ Press the drive mode switch. After the rst press, the weakest economy mode is activated. The motorcycle works at 50% of its own
maximum power. The LED indicates the ECO mode in green. After the second press, the LED lights up blue and signals the middle perfor-
mance level. In this SPORT mode, the motor power is set to 75% of the maximum power. The third press activates the motor at its maximum
RACING power and the LED is red. When pressed again, the motorcycle switches back to the "green" economy mode.
In case of a fall and pulling out of the "tug", check all elements of the motorcycle. Connect the tug magnets. The performance map status LED
lights up white. The motorcycle acoustically announces readiness to ride. Switch on the selected driving mode and continue driving.
3.4. Stopping the motorcycle
1/ Disconnect the "tug" when you stop driving. The map indicator LED goes out.
2/ Then disconnect the battery with the main switch by turning it to the OFF position. The battery indicator turns o when the battery is
turned o.
3.5. Motorcycle range
The range is inuenced by many factors, especially by terrain, rider’s weight, gear selection, outside temperature and riding style.
O-road travel is 60 km depending on speed and selected mode / 2,5 hours in terrain / 1 hour in Racing mode.

14
3. Operation
3.6. Driving instructions
1/ Avoid incorrect and dangerous driving style. Always operate the machine with sucient respect.
2/ Never drive while under the inuence of alcohol, drugs or other addictive substances.
3/ Always use the right equipment including helmet, shoes, gloves, etc.
4/ Do not hang any objects on the handlebars or other parts of the motorcycle while driving.
5/ Don't bring anyone else with you. Drill is designed for one rider only.
6/ Please respect the laws and the natural environment.
7/ The motorcycle may overheat if the maps are selected incorrectly or if the driving direction is unsuitable. To prevent damage to the motor,
it is equipped with a temperature sensor directly inside the motor. When the temperature inside the engine reaches 75°C, the engine
control unit will limit its performance. Full engine power will not return to its original level until the engine temperature drops below that
level. If you park the motorcycle in hot weather at the moment when the temperature inside the engine reaches 75°C, the engine tempera-
ture can rise further, because the engine stops being cooled by the air supply.
If the temperature rises above 80°C in this situation, the motorcycle will be switched o completely. It starts to react only when the
temperature drops below 75°C. If the engine shuts down due to overheating, take o the tug, turn the switch to the OFF position, and start
the motorcycle as usual after cooling down.
8/ Use all performance maps while riding the motorcycle. Use the green map to drive slowly and save energy. Use blue map when driving
o-road and especially on long rides. When driving at full speed, do not drive on the blue map for more than 60 seconds. The red map is
intended primarily for the purpose of fast acceleration, short steep rides, overcoming obstacles, where you need to have maximum power
and engine torque. The red map is not suitable for continuous driving, especially at full throttle. If you use the red map, do not drive at full
throttle for more than 20 seconds.

315
3. Operation
3.7. Instructions for parking the vehicle
Drill is built to work in all nature conditions, but hot or extreme cold can aect it when standing or driving. Drill operating temperature is
between -5°C and 35°C. When batteries are exposed to low temperatures, performance and range may be reduced. Do not leave the vehicle
parked outdoors for long periods of time when the outside temperature is below 0°C. Do not charge the battery if it is super-cooled or at
temperatures above 40°C (for example, in direct summer sunlight). You can damage the battery and reduce its battery life. If you are not using
the Drill in winter, it is recommended that you fully charge the Drill at least once within 30 days.
3.8. Motorcycle suspension
Suspension ensures comfort, safety and handling when driving. Always have the suspension serviced or repaired by an authorized service
center. Do not remove the shock absorber or the fork yourself. Damage caused by improper handling will void your warranty. Never use
pressurized water to clean components.
3.9. Rear shock-absorber functions and settings
At the rear of the machine you nd a central suspension and damping unit, in short and commonly used silencer. The shock absorber is
compressed under load and extended again after release.
The squeezing of the spring is called compression. Compression can be set. It is thus possible to set the force by which the spring must be
compressed. This force can be increased or decreased. After compression (compression of the spring), the compressed spring begins to return
to its original position. This is called rebound.
By adjusting the bounce it is possible to change the time how long it will take for the spring to return to its original position after compression.
.

16
3. Operation
Depending on the weight of the driver, it is also possible to adjust the spring preload and thus aect the so-called rear shock absorber, or the
length by which the rear shock absorber drops below the rider's weight. Each driver must adjust the sag in relation to his weight by changing
the preload settings. It is recommended to set the sag to 10 - 20 mm depending on the driving style. Longer sags are more comfortable, while
smaller sags allow for more aggressive driving. Correct sag, preload, compression and rebound settings are essential for this machine to
function properly.
3.10. Fork functions and settings
The fork is compressed under the load and lengthened again when released. The front fork behaves in the same way as the above-described
shock absorber. The squeezing is called compression. Fork compression can be adjusted according to the rider's style and weight by adjusting
the spring preload. After compression, the compressed fork begins to return to its original position. This is called rebound.
By adjusting the bounce it is possible to change the time how long it will take for the fork to return to its original position after compression.
The fork is also equipped with so-called air chamber and control valve. Do not handle the valve. The new fork needs approximately 20 hours of
use to function properly. Regular maintenance, cleaning and adjustments are required for the fork to function properly.
3.11. Brakes
Check the condition and functioning of the brakes before each use. Always have the brakes serviced or repaired by an authorized service
center. Always test the brakes visually and functionally before driving, also again on a at and non-slippery surface several times. Brand new
brakes need to be driven to achieve the highest braking force. This means, in practice, starting the vehicle at least 20 times to 30 km/h and then
brake fully.

17
3. Operation
The pressure must be steady when the brake levers are pressed. The brake levers must not decrease further under pressure. If this occurs, it may
show a serious malfunction. In such case visit your Drill dealer immediately.
Moisture reduces braking eciency. The stopping distance is longer when it is wet and slippery. Dirty or greasy brake pads and discs can
signicantly reduce braking force. Therefore, make sure that no oil or other similar uid gets into the brakes, for example when lubricating the
chain. Never wash the brake pads impure by oil and always replace them with new ones. On contrary, the discs may be washed with a special
brake cleaner, or hot water and a conventional cleaner.
Contact an authorized service center to adjust the brake levers correctly.
Continuous braking can reduce braking eciency and even lead to extreme brake failure in extreme situations due to overheating. Do not
touch the disc or the brake caliper after a long downhill run to avoid burns. Learn to brake with both brakes at the same time! Stop at the rst
signs of overheating, i.e. when the brakes appear to be defective or when more force is required to brake, or smell or hear strange noise. Allow
the brakes to cool before continue riding.

4. Maintenance
4.1. Brake maintenance
1/ Check the brake pads for wear before each ride (min. thickness 2,5 mm).
2/ Always check for wear and damage (min. thickness 1,8 mm) before each ride.
3/ The thickness of the discs should not be less than stated value. If this happens, replace the discs immediately.
4/ Check the connections of hydraulic brake hoses before each ride (there should be no cracks in the cable, the brake uid must never leak).
5/ Wash the brakes if they are very dirty.
6/ Always have the brake serviced by an authorized service center.
4.2. Rims, tires, hubs
1/ Always check the condition of rims, tires and hubs before driving.
2/ Before driving, check the tires for cracks, cuts, bumps or bulges.
3/ If you notice any damage or abnormalities on the tire, replace it immediately.
4/ Check the tire pressure and condition before each ride.
5/ Check the minimum tread depth and, if smaller, replace the tire. The recommended tire pressure is 1,2 - 3,5 bar.
6/ Check the condition of the wheel hub regularly. Focus on runout and any cracks or other mechanical damage.
7/ Check the wheel wires for tightness. Loose wires can negatively aect vehicle behavior and stability.

19
4. Maintenance
4.3. Wheels disassembly
4.3.1. Removing of the front wheel
1/ Place Drill on the mounting stand.
2/ Unscrew the central nut of the wheel axle using an Allen key.
3/ Loosen the 4 screws from the bottom of the fork with the Allen key. Do not unscrew the screws completely.
4/ Lift the wheel slightly upwards so that it does not rest with its full weight on the wheel axis, pull out the wheel axle.
- Before each operation, make sure the vehicle is switched o.
- Be careful, the wheel is released when the wheel axle is removed.
- To replace the wheel, perform this process in reverse order.
- Never press the front brake lever unless the front wheel is tted.
- When retting the wheel, be careful to insert the brake disc back between the pads.
4.3.2. Removing of the rear wheel
1/ Place Drill on the mounting stand.
2/ Loosen the rear wheel axle nut bolt.
3/ Release the chain from the rosette.
4/ Remove the rear wheel axle nut bolt and pull out the rear wheel axle.
- Before each operation, make sure the vehicle is switched o.
- Be careful, the wheel is released when the wheel axle is removed.
- To replace the wheel, perform this process in reverse order.
- Never press the rear brake lever unless the rear wheel is tted.
- When retting the wheel, be careful to insert the brake disc back between the pads.

4. Maintenance
4.4. Gears, chain
1/ Check all gears regularly for wear! If the primary or secondary gears are in poor condition, visit your Drill dealer for replacement.
2/ Check the chain for wear.
3/ Clean and lubricate the chain after each ride.
4/ Use products designed for this purpose.
5/ Check the chain tension regularly as shown on the illustration. The gearwheel is located in the oscillation axis, thus the chain tension can be
higher than in other constructions, because the chain does not stretch during the springing. The chain tension should be within 1 cm.
Perform the tension as follows:
1/ Place Drill on the mounting stand.
2/ Loosen the rear wheel axle nut bolt.
3/ Rotate the tensioner symmetrically at both ends of the wheel to tighten the chain.
4/ Check the rear wheel symmetry from the rear and tighten the retaining screw.
