    What to do if my Hytorc Stealth 8 Power Tool ratchet does not take successive strokes?

      If the ratchet does not take successive strokes, the square drive or the ratchet spring may be defective, requiring replacement. Also, ensure the piston fully retracts. Another possible cause is damage to the linkage between the piston rod and the drive plates, which would also require replacing the defective part.

    Why does my Hytorc Stealth 8 lock onto the nut?

      Kayla VasquezSep 13, 2025
      If the tool locks onto the nut, it is likely that the square drive is loaded at full torque. Use the disengagement lever to remove the tool from the nut or bolt.

      If ice builds up at the exhaust, the ambient temperature is likely too low. Wait 5-10 minutes to let the ice melt.
