Adjusting your BullDog Key
Do not use tools - Damage may result

NOTE: Adjust spacing first then adjust tension.

TO ADJUST SPACING:  Spacing adjustment is accomplished by bending the stop wires. The stop wires are the wires that protrude out the top of the key and bend down to act as a stop for the paddles. To increase the spacing use the paddle as a lever to very carefully bend out the stop wire to open the contact gap.  To decrease spacing carefully compress the paddle wires near the socket joints just enough to allow the paddle to swing to the outside of the stop wire. Again, using the paddle, bend stop wire to close the gap.  Alternately bend the stop wire back and forth until the desired spacing is obtained.

TO ADJUST TENSION:  Compress the paddle wires near the socket joints just enough to allow the paddle to be removed completely from the key.  To increase tension spread the paddle wires apart.  To decrease tension, squeeze the wires together.  Reinstall the paddle. Caution: Compress the paddle wires just enough to re-insert.  Check the up/down movement of the paddle by very gently applying up/down pressure.
If any movement or looseness is encountered the tension is too loose for proper operation.
