Elecraft KXPD3 - Manual (Page 3)

Contact Spacing Adjustment
Each paddle has a contact adjustment screw and a locking screw that keeps the contact adjustment screw from
turning. A wrench for each screw is provided with your KPD3. Be sure to loosen the locking screw before
turning the adjustment screw. Do not over-tighten the locking screws. You can damage the threads of the
contact adjustment screws, making further adjustment difficult.
If you back the contact adjustment screw out too far it will no longer reach the stationary contact and the
paddle will stop activating the keyer.

Spring Replacement
The KXPD3 is supplied with a medium weight spring installed. If you’d like a lighter or heavier touch, suitable
springs are provided with your paddles. Replace the spring as follows.
Remove the KXPD3 paddles from the KX3.
Use the 3/32” (0.09”) wrench to remove the three screws shown in Figure 4 and lift the top cover off while
holding the paddles closed. The top cover is a tight fit. If you must let go of the paddles to remove it, one or both
levers may fly off under the spring tension. If that happens it is easy to reassemble, but take care not to lose any
parts. The pivots (Figure 4) may stay in the bottom or come out with the paddle arms.
