3. Causes and countermeasures of disc brake noise
The disc braking have good braking power so many electric scooters use the disc brake.
However, you may hear a sharp hissing sound when you hold the disc
brake because of dust or sand particles on the ground popping up 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.
If that happens, clean the inner surface of the disc by turning the
wheels with a clean, dry cloth and straighten any bent discs.
4. How to adjust handlebar gap
If there is a free gap on the handle, use a 2.5mm or 3mm hexagon wrench to fine-tune the adjustment bolt that is visible when the
handle is folded, then extend the handle to check the free gap condition. If there is a gap, rotate it a little until there is no gap.
* CAUTION : When adjusting for free gap, do not fully unfold the handle when the bolt is protruding more than
necessary, and excessive coupling may cause external damage to the handlebars. If the handlebars are not
normally combined with the handlebars, tighten the adjusting bolts clockwise again to reduce the protrusion.
5. How to adjust the gap in the folding section
If there is a free gap in the folding part, tighten the folding knob completely to clear the free gap.
If product folding is not required (always unfolding)
Remove the bolt protection caps on both sides of the front folding hanger and
tighten the bolts to ensure that they are un-folding at all the time.
If you work in reverse order, you can do folding.
If you maintain the product using the above methods, please visit the
nearest branch and get a safety check as there may be another problem.
