If you experience excessive bit wear
Replace the bit and try to apply more down pressure when driving screws. Next, check to see if the clutch on the
power screwdriver/screwgun is working properly. Remove the CH7390 from the screwgun and turn on the screwgun.
If the bit turns as soon as it is activated and the bit is not pushed in, then there is a problem with the clutch. The clutch
may be worn or need repair, the bit holder should be spring
-
loaded outwards and smoothly operate when pushed
inwards.
Removing a Strip of Screws or If a screw is jammed or stuck
Rotate the feed lever slightly and
hold down
the feed latch button to allow the feed latch to clear the screws. Wiggle
the screws gently and withdraw the strip of screws.
