• Place the backrest support tube (AT1)
into the bracket on the top of the main
frame (AB1). The rubber bumper should
be facing down. Line up the holes in the tube
with the back set of holes in the bracket.
Slide a lock washer (10.2x18.4x2.5)
and a flat washer (10.2x22x2) onto a
bolt (M10x25) and fasten to the left and
right side of the back holes. Repeat this
process, attaching the seat support tube
(AT2) to the main frame’s (AB1) front set of
holes. After attaching, retract the pull pin
and position it in one of the holes in the
seat support tube (AT2).
• Place a bushing (T10) into the left and
right side holes of the backrest support
(AT1). Slide a bolt (M12x115) and a flat
washer (13x26x2.5) thru both holes of the
seatback angle adjuster (AT3) and the
backrest support tube. The adjuster’s handle
should be positioned on the right side of
the bench when looking from the front.
Attach a flat washer (13x26x2.5) and a
nut (M12) to the end. Do not overtighten.
The seatback angle adjuster should move
freely when transitioning the backrest.
• Slide the accessory tube (AH2) into the
accessory receiver tube (AH1), with the
vertical holes to the rear. Disengage the
pull pin first, then slide the accessory tube
in and engage the pin in one of the
vertical holes.
