WET A COTTON SWAB WITH RUBBING OR DENATURED ALCOHOL. NOTE: Cleaning rod is too big to be used on receiver bores. A cotton swab must be used.

Cleaning the bore is important for allowing the maximum power transfer from the piston while striking the back of the receiver and transmitting this force to the tip of the graver or setting tool.

CLEAN PISTON & SPRING
CLEAN QC HOLDERS
ALLOW ALL PARTS TO DRY COMPLETELY BEFORE REASSEMBLING. !
Lay out piston and spring on clean pad and wet with rubbing or denatured alcohol. Gently scrub with wet pad until clean.
Wipe down each QC holder with a pad and rubbing or denatured alcohol to remove debris.

LUBRICATE QC HOLDER BODY
APPLY SMALL AMOUNT OF SYNTHETIC GREASE TO FINGER.
Rub synthetic lightweight lubricant on the QC holder body. This will keep the O-ring from drying out and cracking, and ensures the holder moves freely in the receiver.
AVOID APPLYING TOO MUCH LUBRICANT. EXCESS WILL ATTRACT DEBRIS ONTO THE OUTSIDE OF THE QC HOLDER.
