1) Clean with tuyong basahan and old tooth brush.
2) Lube with WD40 or Singer oil or kahit cooking oil pwede..
3) let it sit for 10 minutes and lube again.
4) Wipe clean and check.
repeat steps 2 to 4 until wala ka nang duming makuha...
If MAGANIT padin.. baka bearings na problema mo dude.. OR baka may bato sa loob ng bearings..
If so, gamitan mo nang bakyum while moving the parts.
pag ganun pa din... pare bilhin mo na yung aking BNEW Gibraltar Single pedal kick ko 2K lang.. with warranty to dude...
Hope this helps..
