Installing the Assist Arm
TOOLS REQUIRED
AWL
LARGE FLAT SCREWDRIVER
PHILLIPS SCREWDRIVER
(small and medium)
ADJUSTABLE WRENCH/PLIERS
1. Position the template cut (from the back of the packaging
card) against either the left or right hand hinge guide
bracket (depending on which chosen side the power pivot
system is to be installed).
2. Using an awl or pencil mark the 6 applicable holes through
the template on to the attic floor (See Figure F).
3. Place the spring housing (F1) in position over the holes
ensuring the arm points AWAY from the rough opening
(with slot in cover on the left-hand side) (See Figure G).
4. Secure the spring housing to the attic floor with 20mm
screws (F3) through the 4 inner holes (See Figure G).
5. Place the housing cover (F2) over the spring housing and
attach using 20mm screws (F3) through the 2 remaining
outer holes (See Figure G)
6. Position the ladder in its fully stowed (closed) position
carefully in the opening.
7. Remove the tack and plastic top cap from the top of the
required side rail of the rear ladder section and discard
(See Figure H).
8. In their place attach Pivot Tip (F4) (See Figure H).
9. Locate the power arm linkage plates on either side of pivot
tip (F4)/ladder rail and align all holes.
10. Secure the rail to the linkage plates using bolt (F5),
washers (F6), nut and nut cap (F7 & F8) (See Figure I).
Ensure bolt (F5) and nut (F7) are tightened sufficiently to
allow the linkage to freely rotate without any looseness.
DO NOT over-tighten the nut as this will restrict smooth
operation of the ladder system.
