To buy a suitable slack adjuster really is not easy, drove to the far Dian Li come to, or not, if I’d known I would go directly to the Internet have a look, because my brother said the store sold, so I will run out, the Dian Li things really many, but we want slack adjuster he really did not have this kind of thing is not good, machinery management, sometimes things need tools to repair it must buy, like this has happened before, so I always feel something to buy it or online shopping, no everywhere, but also does not have results.
