Why should I pull it up a few times? Because the friction should stop gradually
This problem is very simple, you just don't know it. The working principle of diesel hammer, hammer force pull up several times in the ignition, ignition after diesel combustion explosive can put the hammer from the top, the hammer reaches a certain height to fall under gravity, in the moment of contact pressure the light diesel (compression diesel can make its combustion is its characteristics), and was the top hammer, again and again.
