Main Chassis Assembly
Step 1 –Hinge and Hinge Base RH
Insert a 1/2" x 1-1/4" long carriage bolt into the top hole of the Hinge Base. Then add a 1/2"
teflon washer (.020" thick) to the bolt. Add the hinge on top of the carriage bolt. Then add a
1/2" metal flat washer and a 1/2" nut. Tighten until you can barely rotate the hinge.
Insert a 1/2" x 1-1/4" long carriage bolt into the bottom hole of the Hinge Base through the
slot of the Hinge. Add a 1/2" metal flat washer and screw on the Large Black Handle (Item 6).
The handle can be adjusted by pulling up on the handle and rotating. You may need to hold
the threaded portion while rotating the handle.

Step 2 –X Brace
Insert X-Brace into the Hinge Base. Slide 5/16-18 nylock nuts into the X-Brace. Secure with
5/16-18 x 3/4” long Button Head Screw by inserting it through the Hinge Base into the nylock
nut.
