• Track Assembly
   Remove slider assembly parts from box
   # 40-7940-0051-000 and insert into channel in the 
   order shown. See illustration on page 2 or 4.
   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 hold open angle for door. 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. This may require turning the hold
   opening force screw (small set screw) with 1/8" 
   hex drive to reduce tension. Tighten the stop 
   position screw (large set screw) with 3/16" hex 
   wrench (from screw pack) until secure. Turn the
   hold opening force screw until desired hold open
   tension is achieved, then release.

• 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.

• 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.
