3• Track Assembly Remove slider assembly parts from box # 40-7940-0050-000 and insert into channel in the order shown. See illustration on page 2 or 4. Use of a hold open device or assembly will void the UL® listing for this product. Insert end caps into ends of track prior to installing.• Install track to frame. Place the assembled slide track against frame with the open side down, stop and cushion blocks toward the hinge. Move the slider to the opposite end of the slide track. Secure slide track with 1/4-20 flat head phillips drive mounting screws.• Connect arm to track. Open door approximately 5"(127mm), rotate arm to slider and place end on stud. Push down on arm and tap gently to seat (to prevent stud from turning during assembly). Secure with 1/4-20 x 5/8" long truss (rounded) head phillips drive screw with thread lock. CAUTION: Closer arm is under spring tension and may be difficult to rotate.• Set door stop angle. Open door to the angle you want the door to stop. With the door held at that location, slide stop with cushion block against slider. Tighten the stop position screw (large set screw) with 3/16" hex wrench (from screw pack) until secure. Release door.• Adjust closer (see page 5) before installing cover. • Install Cover. Slide insert into cover slot (see illustration). Fasten cover to closer with (2) 8-32 x 1/4" long round head phillips drive screws. Installation Sequence Pull or Push Side Mount• Determine hand of door and type of installation from illustrations on page 1. • Use template dimensions to locate fastener holes on door and frame. See "Preparation for Fasteners" chart below. 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, prepare holes for 7786 drop plate instead of closer. Secure drop plate before mounting closer. • Fasten closer to door or drop plate. Position spring tube away from hinge. See arm indexing illustrations (above right) for valve positioning (up or down). Secure mounting screws.• 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 page 2 or 4.• Install arm on closer pinion see arm indexing illustrations (above right). Position slide arm with counterbore facing up and align with pinion flat as illustrated. Install onto pinion. Secure with washer and flat head phillips drive arm screw with thread lock.
