Installation Sequence (Pull or Push Side Mount)

1. Determine hand of door

Using the illustrations on page 1, determine the hand of door and type of installation.

2. Use template dimensions to locate fastener holes on door and frame . Refer to pages 3 and 4 to locate fastener holes on door and frame. Refer to "Preparation for Fasteners" chart for fastener information.

Frame : Prepare the frame for mounting track. Drill and tap holes for 1/4-20 machine screws or #14 wood screws.

Door : Prepare the door for mounting closer. Drill and tap (4) holes for 1/4-20 machine screws, #14 wood screws, 3/8 diameter sex-nuts, or through bolts and grommet-nuts.

NOTE: If drop plate is used (see page 4), prepare holes for 8148/8548/8158 drop plate instead of closer. Secure drop plate before mounting closer.

3. Fasten closer to door or drop plate.

Position closer with:

Pull side : Power adjustment shaft away from hinge Push side : Power adjustment shaft toward hinge Secure mounting screws.

NOTE: If using full metal cover, mounting clips must be slipped under ends of closer when closer is being mounted. Clips should project 1/4" (6 mm) from each end of closer.

4. Assemble Slide Arm . Insert flat arm rod into arm tube with the counterbore screw hole facing up. Align counterbore with the 3rd hole in the arm tube and secure with 8-32 x 1/4 long hex socket cap screw. See illustration on pages 3 or 4.

5. Install arm on closer pinion.

Refer to arm indexing illustrations below:

Pull mount:

Position slide arm with counterbore facing up and align with pinion flat as illustrated. Install onto pinion.

Push mount:

With "S" & "L" valves closed, place arm on closer pinion shaft with arm at a 45° angle to frame face. Rotate arm toward hinge at least 50°.Remove arm and reinstall on pinion with arm almost parallel to frame face, before pinion shaft can rotate far enough to create interference with door.
