STEP 3
Assemble the backrest into the receiver on a bench or sturdy table. PIC 1 With a flat blade screw-
driver, turn the setscrew in (clockwise) to increase the tension against the backrest upright. Turn
the setscrew out (counterclockwise) to decrease the tension. Adjust the tension so that the back-
rest pulls out with resistance. This will allow the backrest to remain in place during use.
Remove the backrest from the receiver.
STEP 4 With the seat underside up on a sturdy bench or table, center the support bracket as
shown in PIC 2. Ensuring that the bracket has seated on the seat pan, press down on
the forward lip of the support bracket. PIC 2 Mark the three holes on the seat pan as
shown in PIC 2. Remove the bracket.
STEP 5
Using a 5/16” drill bit, drill a hole in the top and bottom of each mark. PIC 2 Do not
drill all the way into the foam. Use a sharp razor knife to connect the two holes and
create a slot. There will be three slots. PIC 2
STEP 6
With the seat top side up, align the
straight edge with the stitching in the seat
and mark the center of the seat as shown
in PIC 3.
STEP 7 Locate the chrome top trim from the kit.
Align the notches on the underside of the
trim with the mark made in STEP 6. Using
it as a template, mark around the INSIDE
of the chrome top trim on the seat. PIC 4
Remove the trim. It is VERY important to
have the top trim centered and even in
relation to the seat stitching.
STEP 8
Using a sharp razor knife, cut around the INSIDE of the reference mark
made in Step 7. Try to cut round corners to prevent potential tearing.
STEP 9
Using a sharp serrated knife, with the sharp edge pointed AWAY from any
wiring, and with slow easy strokes, carefully cut the seat foam aiming for
the three slots in the seat pan. PIC 5, 6 and 7 The slot in the seat foam
should be approximately 1/2 inch X 2inches. PIC 8 Remove just enough
foam to allow the receiver to be installed inside the seat and make con-
tact with the inside surface of the seat pan. Note the angle of the seat
pan and how the receiver will contact it. PIC 5 and 6 Be Patient!
