Fix the spring housing to the loft floor with 4 x
20mm screws (F3) through the 4 inner holes.
Place the housing cover (F2) over the spring

Installing the Power Pivot System
Position the template cut from the rear of the
header card against either the left or right hand hinge
guide bracket (depending on which chosen side the
power pivot system is to be fitted).
Using a bradawl mark the 6 applicable holes
through the template on to the loft floor.

WARNING:
Do Not stand on the ladder to do this. Either using a
second ladder, or from inside the loft space, secure
the hinges using six 35mm screws supplied.

If flooring material covers the top edge of the loft hatch frame ensure that it is completely stable and if necessary
use longer screws to penetrate the frame itself.
The ladder should now be free to swing from the hinges and slide freely up and down the guides.
Installing the Ladder
N.B. The ladder should be installed on the same side
of the trap as the trapdoor hinges.
With the ladder preferably centred in the
opening, and the trapdoor hanging down, locate the
hinge guide bracket arms (B1 & B2) on the top edge
of the loft hatch frame (see diagram).
Make guide holes with the bradawl then pre
drill pilot holes (2mm diameter) for all screws.
Fix using 35mm screws (B3).
N.B. the bracket arms with two screw holes should be
on top.

Handrail Assembly
The handrail (G6) can be fitted to either side of the loft
ladder. It is advisable to fit the handle only after fitting
the power pivot arm.
Fix the handrail to your chosen side of the
rear frame.
Use 3 x spacers (E1), 60mm bolts (E2),
washers and nuts (E3 & E4) supplied.
You have a choice of 2 different handrail
heights which will be dependent on the amount of
“in-loft” handrail you require.
Check that all fixings for the whole assembly are fully
secure.

9.1
Locate the power arm linkage plates either
side of pivot tip (F4)/ladder stile and align all holes.
Secure the stile to the linkage plates using bolt
(F5), washers (F6), nut and nut cap (F7 & F8).
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.

Operating the Ladder
Locate the plastic stowing hook/key (G3) into
one end of the stowing pole (G2) and push firmly to
ensure the plastic stowing hook/key (G3) is fully located
within the pole. Secure hook/key (G3) with screw (G7).
Push the plastic end plug (G4) into the opposite end of
the stowing pole (G2).
To open the trapdoor locate the key (G3) into
the slot in the catch operator (A1) and turn the catch
anti-clockwise until it reaches the travel stop and then
lower the trapdoor.

Stowing the Ladder
Retract both right-hand side catches ‘C’ & ‘D’
(blue) and rotate both catch levers upwards into the
locked open position.
To stow the ladder, retract catch ‘A’ (black), slide
the front frame fully upwards until catch engages again.
Repeat step 11.2 for catch ‘B’ (black) and the
middle ladder frame.
Engage the plastic stowing hook/key (E3) over
and at the centre of the REAR ladder section bottom
rung and whilst maintaining the stowing pole near
vertical push the ladder vertically upwards.
Continue to slowly push the ladder up and fully
into the loft.

WARNING:
DO NOT attempt to climb your loft ladder until you
have:
Checked that it is pulled down to the stops.
Fully read all safety labels and ensured that it is
set at the correct angle.
Ensure that the locking catches are fully engaged.
Locate the stowing hook/key (E3) over and at
the centre of the REAR ladder section bottom rung and
steadily pull the ladder outward and downward until
both top stops reach and make contact with the hinge
guides.
10.3
To extend the ladder, retract left-hand catch ‘A’
(black) while supporting the front frame of the ladder.
Lower the frame slowly until catch ‘A’ (black) engages
again.
Then retract catch ‘B’ (black) and lower the
middle frame until catch ‘B’ (black) is engaged in your
required position. Extend the ladder until the feet rest
firmly on the floor.
When the ladder has been fully deployed, rotate
both right-hand side catch levers downward to unlock
and release both catches ‘C’ and ‘D’ (blue) and ensure
both catches are fully engaged. Do NOT use ladder with
any catches (‘A’, ‘B’, ‘C’ or ‘D’) disengaged. Read the
safety labels on the product.
10.5
10.6
Ensure the ladder is pulled down so that the top
stops or additional top stops if fitted rest firmly on the
hinge guides. This supports the top section and
prevents it sliding down when climbed.
Check the ladder angle against the safety label
or refer back to deployed requirements on page 1.

Retract both right-hand side catches ‘C’ & ‘D’
(blue) and rotate both catch levers upwards into the
locked open position (see diagram).
