Product Description
The Porter Cable 7424 Dual Action Polisher is designed to move both in an orbital motion and a jiggling motion. With all that movement, the polisher may become unbalanced and the user has to compensate for the added wobbling. This problem is easily corrected with a counterweight. The counterweight fits on the eccentric housing, located just above the backing plate. This is the part that causes the plate to spin. The semi-circular weight spins with your backing plate to balance out any irregular motion and make the Porter Cable operate more smoothly. With the addition of a counterweight, your Porter Cable 7424 will work like a charm and render a perfectly uniform finish every time.

Technical Details
- The counterweight is for use with a 6 inch backing plate only.
The counterweight is a half-moon shaped piece of metal attached to the rotating shaft of the tool. This smooths out the random orbit action by providing a counter balance to the elliptical orbit of the rotating backing pad. If you change the pad size you must also change the counterweight or suffer unnecessary vibration and possible damage to the tool.
There are two different counter-weights which are clearly marked to indicate use with either the 5" or 6" backing pad. Therefore if you decide to outfit the 7335 5" Sander with a 6" backing pad for sanding or polishing you must switch to the counterweight used with 6" backing pads. The same goes for the 7336 6" Sander. If you decide to outfit it for 5" sanding or polishing you must switch to the counterweight used with 5" backing pads.
The only exception is when using the 54745 6" Foam Polishing Pad. Due to its light weight and the small-diameter backing pad used (included with pad), it can be used with the 5" or 6" pad counterweight. Porter-Cable outfits the 7424 Car Polisher with the 5" pad counterweight.
