During final tightening, if your hand does not feel an increasing force on the nut or bolt
as
you pull, the nut or bolt may already be tightened excessively. The nut or bolt may
be very close to breaking. Replace the nut or bolt with a new one.
3. Loosening operation
To
loosen the nut or bolt, turn the tool over (upside-down). Loosen the nut or bolt by
pulling on the tool grip manually in the loosening direction. Then turn the tool on to
quickly and efficiently remove the nut or bolt.
