Safety guidelines before driving Maintenance
• The brake braking force is sufficient to check the operating condition. If the braking force is significantly
lowered, use it immediately after inspection and action.
• Check that the brake pad is not worn, that the cable is not loose, that the cable is not
damaged, or that there is no leakage in the case of 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 the home 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 clearance of the QR lever on the handle.
*
If there is a folding clearance,
If there is a folding clearance, it can be adjusted with a tongue bolt. However, if
you pull it too hard, it will become stiff without a gap, but it may sound '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 counseling is available..
●
Unusual heating of the motor
●
Brake braking status error
●
Error messages on the instrument cluster
●
When the throttle is returned to its original position
●
When the throttle is returned to its original position
* In this case, stop driving immediately.
Danger
●
abnormal noise is generated
●
Product smoke, ignition, sour odor
●
When rain or wet with water or in a similar situation
●
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.
①
The 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
①
Replace 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.
②
If the product is exposed to strong sunlight for a long time, discoloration may occur.
③
In 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.
④
Fatigue 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
puncture increases, 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
