The backcheck should be adjusted to match the movement of the arm.
Once the backcheck is adjusted, test the operation of the door closer to ensure proper operation.
LCN has developed a snap-on plastic cover for the 4040XP door closer. There is a clip that is snaps on to the closer body tube. There are two cutouts for the pinion and the clip, depending on the hand of the door. LCN recommends locating the clip in the proper cut-out, then “snapping” the cover directly onto the closer body. When the installation is completed, write the date of installation onto the door closer body. This way, should the closer need repair, you will know if it is still under warranty.
LCN 4040XP door closers are available with a powder coat finish, plated finish on the arms fasteners and metal cover as well as a SRI primer with powder coat finish for installation in corrosive conditions. The snap-on plastic cover is standard; the metal cover is optional.
