* Precautions when usingelectronic brake immediately after full battery charge
The electronic brakes do notoperatewhen the batteryis fully charged, so besureto
checkandoperate this device. When the batteryruns out,the electronicbrake will operate
normally.
* Precautionswhen using the ABS function
ABS has the advantage of being able to stop attheshortest braking distance that can be
obtained from the tires and road conditions. However, due to the principle of repeatedly
holding andreleasing the brakeseveral times in a second, a lot of vibration occurs in the
motor and the body. Repetitive vibration caused by this may causefrequent loosening of
the motor, rim, fixing partand body fixing bolt.
* ABS brake is an abbreviation of Anti-Lock Brake System. It uses the principle that maximum static
friction force is larger than kinetic friction, so that braking distance (distance from breaking to
stopping) is shorter than that of normal brake. It has the advantage that the vehicle does not slip
well when wheel is rotating.andit is a brake assist system that can stop more safely without wheel
lockand slip.
(1) ABS function ON
Set the ABS function part Pdof the dashboard to 1.
(2) ABS function OFF
Set the ABS function part Pdof the dashboard to 0.
* Pd - When the ABS function is ON, the PA -
electronic brakefunction is canceled.
All electric motorcycles are subject to sudden braking, causing the wheels to stop spinning. As a result,
the slip of tire causes the driver to fall down, which can cause accidents. This product is equipped with ABS
brake function to hold the tire lock, enabling more secure braking.

Safety guidelines before driving Maintenance
• The brake braking force is sufficient to check the operating condition. If the braking force is significantly
lowered, useit immediately after inspection andaction.
• Check that the brake pad is not worn, that the cable is not loose, that the cable is not
damaged, or thatthere is no leakage in the caseof hydraulic brakes.
• If there is an unusual feeling or noise during operation, check for breakage, wear and
deformation of the inner wire of the brake cable.
• Check that the bolts and nuts of the brake fixing parts are not loose, and that the disc
is not deformed or damaged.
• Operate the accelerator throttle lever about 2 ~ 3 times to check whether it returns
to thehome position.
• Be careful that excessive throttle leaning and manipulation of the throttle can cause
malfunction due to internal parts damage.
• Check the fastening condition and clearanceof the QRlever on the handle.
*If there is a folding clearance,
If there is a folding clearance, itcan be adjusted with a tongue bolt. However, if
you pull ittoo hard, it will become stiff withouta gap, but it maysound'crackling'.
In this case, if you adjust the tune bolt properly, the noise disappears and the
clearance is also adjusted.
If you encounter any of the following situations while driving, stop driving immediately and
contact your nearest branch or service center for proper measures. If you provide pictures and
videos to get accurate diagnosis, professional counselingis available..
●Unusual heating of the motor
●Brake braking status error
●Errormessages on theinstrument cluster
●When the throttle is returned to its original position
* In this case, stop driving immediately.
Danger
●abnormal noise is generated
●Product smoke, ignition, sourodor
●When rain orwetwith water or in a similarsituation
●When other driving is judged to be unreasonable
1) Required checking before use 2) Maintenance and self-maintenance
Electric products can be damaged by various factors. The life span of each part
varies depending on driving habits and driving environment. Parts that exceed the
service life may cause accidents. Let's manage various parts and prevent safety
accidents in advance.
※The rubber inside the rubber suspension is cured as the consumable parts are used, and the
performance of the suspension is slightly reduced because of the reduced elasticity.
①The components and suspension parts of the car swing arm, tires, tubes, wheels, bearings,
headset bearings, discs, brake pads, cables and folding parts, various brackets and other
consumable parts requiring periodic inspection And always check.
2. External damage inspection by driving environment
①Replace parts that may be damaged by external driving environment, such as deformation of
parts, cracks due to compression, and signs of exceeding fine gold or life expectancy.
②If the product is exposed to strong sunlight for a long time, discoloration may occur.
③In case of heavy driving such as normal jumps, slight impacts such as turning, collision, etc.,
when driving frequently or for a long time in a poor road condition or driving for thousands
of kilometers or more, fatigue breakdown phenomena Please check and replace the parts
replacement schedule for each product for safety.
④Fatigue breakdown and maintenance parts may
differ from the example conditions depending
on the driving environment and the operating
conditions. Also check parts other than the
replacement cycle (maintenance parts) at all times to check for any signs of abnormality.
2. Check brake and cable
• Check the front and rear tires for wear and punctures and check the proper air pressure
(45 to 50 psi) for the tire. When the shortage of air is shortened, the possibility of
punctureincreases, so check always.
• It is necessary to judge the replacement time by observing the appearance of the tire
such as tire damage, uneven wear.
3. Check tire pressure and uniaxial condition
• Make sure that the bolts and nuts of all parts of the product are tight and free from
loosening. Check the fastening condition and clearance of the folding and fixing
parts of the handle (QR lever, fixed slide, hinge center bolt, headset nut, swing
arm, etc.)
4.Tightening check such as folding part and handle part
Danger
1. Check the replacement timing of consumable parts
18 Dualtron Thunder II User Manual Dualtron Thunder II User Manual 19

Maintenance
* Metal vibration may occur due to motor vibration, vibration of the brake disc and pad
during the load section that accelerates during driving. (About 15 ~ 30Km, different for
each product)
This is a phenomenon in which all revolutions (fans, automobiles, ships, etc.) are
vibrating at a specific rotational frequency (rpm) rather than the product. However, if
the continuous noise or metal noise is large, there is a possibility that the disk is bent
anddeformed.
* Please note that after running, there is a risk of burns due to the heat on the motor
andbrake(especially disk rotor)side.
* Be careful that the bolts of the motor, rim and motor shaft due to the ABS function
may beloosened.
Important notice3. Causes and countermeasuresof disc brake noise
The disc braking method uses a disc brake method with many
electric kickboards because braking power is good. However,
if you get a sharp hissing sound when you hold the disc brake,
dust or sand particles on the ground will spill out on the surface
of the disc, causing foreign substances to be on the brake pads
or disc surface, or bending due to heat or external impact. At
this time, clean the inner surface of the disc by turning the
wheels with a clean, dry cloth, or straightening thebent discs.
If the above measures are not taken, please visit the nearest branch and take a
safety check. There may be another problem.
Caution
3) Maintenance by self-maintenance
1. Brake adjustment method
If the braking force decreases due to overheating of the oil,
damage of the oil hose, loosening of the brake lever, oil
leakage, etc. after using the brake for a long time on the
downhill road, stop using and use after checking it.
2. Tire replacement method
1. After removing the calipers, remove the motor using 18mm
spanner and disassemble the wheel andmotor fastening bolts.
2. Remove thewind from thetires and press the tires off the wheel.
3. Replace the tires and complete the assembly of the tires in
reverse order. Tighten the assembled tire to fit the body, then
tighten thescrews and bolts.
*caution
●After completing the tire replacement, try a simple test run with the appropriate air pressure (45 to 50
psi).
●When puncture is occurred, it is possible to use repair by using patch seal. Please use the tire while
checking and checking continuously.
