Inspection
Take care of your Microlite. The Microlite is designed for trade and industrial
use but is not indestructible.
Clean the Microlite. Remove all debris particularly corrosive materials such as
cements and plaster.
Check
1) There is no damage such as dents, splits, holes, excessive wear or gross
distortion. Very minor distortion is acceptable as long as the Microlite sits
evenly and has not been re-bent after damage. See dimensions on page 2.
2) Both wheels are secure and undamaged and the tyres are clean and not
loose, swollen or excessively worn.
3) Both spring clip assemblies are secure and springs are not stretched.
4) No repairs of any sort have been made.
5) Both hooks are in line see below. The bottom hook is especially
susceptible to damage if the ladder is dropped/bombed with the Microlite in
place.
Inspect hooks
Place a straight edge (ruler or other)
against hook ends. Ensure that bottom
and top hooks run in line along the
straight edge.
Inspect hooks
Push both hooks against the
ladder rungs. The hooks should
run parallel with the ladder stile.

Working above 10 metres. The Microlite
should be secured with a ratchet strap
when accessing a roof above 10 metres.
Wrap the strap around the lower rung
and the lower back bar of the Microlite.
Tighten to secure.
Fit the Microlite while the ladder is on
the ground.
Feed the ladder through the Microlite.
Engage hooks over two rungs. See
erection pages 6 and 7 for the correct
rung positions.
The 80mm lower hook allows the
Microlite to fit rung pitches from
250mm to 290mm. The position of the
rung on the hook will vary according to
the rung pitch.
Engage spring clips under the lower
of the two rungs. Attach with the back
of the clips facing out to ensure that
springs do not get knocked off.
Fitting
The Ladderfix Microlite is a class one ladder stand off suitable for use with all
popular patterns of ladder (except C section ladders) which are properly erected
On firm level ground or with a proper safety base.
Important
Spring adjustment
There are two settings for the spring assembly. Choose the one that gives
positive grip with the least tension.

Erection
The Microlite is designed to rest safely on walls, window sills, sloping and flat roofs.
After fitting the Microlite
Extend the ladder to required height and up-end. Alternatively rest the Microlite on the
wall. Incline the ladder more steeply than 1 in 4. Check stability then extend and roll the
top section of the ladder up the wall.
Ladder angle The ladder should be A tolerance of plus or minus 5 degrees
set at an angle of 1 in 4. is acceptable for the Microlite to still
operate safely.
If tying off the ladder using a ratchet strap.DO NOT over tighten as this can
inadvertently change the angle of the ladder, impose undue stress and affect the correct
sitting position of the Microlite.
The use of a luggage strap instead of a ratchet strap stops the risk of over tightening.
WALLS, WINDOWS AND WINDOW CLEANING
SLOPING ROOF, FLAT ROOF AND GUTTERS
Walls Hook the Microlite over rungs
1 and 2 of the ladder.
Extend, up-end, check angle and rest
both wheels firmly in position.
Windows
Either
Hook the Microlite over rungs 2 and 3.
Extend, up-end, check angle and rest
both wheels firmly in position just below
window sill.
Or
Hook the Microlite over rungs 2 and 3.
Extend, up-end, check angle and rest
both wheels firmly on top of the window
sill and up against the bottom of the
window frame
Sloping roof
Hook the Microlite on rungs 3 and 4 or
rungs 4 and 5 of the ladder, creating a
minimum handhold of 1 metre.
Position both wheels on the roof so that
the ladder is supported just clear of the
gutter.
Adjust ladder angle and allow the
Microlite to settle into place, making
sure that the ladder stiles are
touching the lower back bar of the
Microlite. This ensures the correct
working position of the Microlite.
When a roof ladder is securely hooked
in place, tie it to the Microlite.
Ensure that the ladder stiles are
touching the lower bar.

SLOPING ROOF, FLAT ROOF AND GUTTERS continued
Wrong flat roof position Right flat roof position
Flat roof Hook Microlite on rungs
3 and 4 or rungs 4 and 5 of the
ladder, creating a minimum
handhold of 1 metre.
Position both wheels on the roof
so that the ladder is supported
clear of the gutter or edge.
Adjust ladder angle and allow the
Microlite to settle into place.
Make sure that the ladder stiles
are touching the lower back bar
of the Microlite. This ensures
the correct working position of the
Microlite.
Gutters When required to
access or clean a gutter,
follow the procedure for
sloping roof. See page 6.
Although the Microlite can
be hooked on rungs 2
and 3 if preferred.
Important
Keep the projecting limbs of the
Microlite as far over the roof top as
possible without touching the edge
Do not allow the wheels to get
trapped in the angle of the reverse
incline or lip at the edge of the flat
roof
Check that the top hook is fully
engaged before climbing

Additional Safety Guidelines
The Work at Height Regulations 2005 should be observed at all times.
Secure ladders at the top with the appropriate Ladderfix model or by tying.
Caution. Ladderfix products are convenient and safe providing that they and your ladder
are in good condition and they are used in accordance with safe codes of practice.
Further Useful Precautions
Winds. Avoid using ladders if winds are more severe than a light breeze and be prepared
for sudden gusts.
Carrying Ladders. Keep the ladder clear of the ground and obstructions, hesitate at
steps, doorways and corners, and look in all directions before changing direction.
Location. Do not erect ladder at doorways without taking particular precautions –
especially fire exits. Make sure that the ladder can be seen and avoided by pedestrians
and vehicles. Corners are particularly risky. Do not forget about blind people and children.
Up-Ending. Close the ladder as much as possible. Check for overhead cables, clothes
lines, trees and other overhead obstructions, then check that the ground is reasonably
clear. Because you may have repositioned the ladder, do the same when bringing the
ladder down. Place the bottom end against wall or kerb, lift the top end and walk forward
holding the middle of each rung in turn, keeping the arms stretched up high. When the top
of the ladder is at rest, bring the bottom outwards.
Stable Base. Do not erect on a box or a free standing tower.
Ladder Angle. Incline ladder at 1 in 4, i.e. 1 going 4 rising. Do not alter to compensate for
poor site conditions.
Outbuildings and Shallow Angles. Do not use ladder at a shallow angle to get to a
window above an outbuilding, staking a ladder does not prevent ladder stress.
Ladder Level. Both bottom stile ends must be on a firm level surface and the rungs
should be more or less horizontal. If the ground slopes sideways use Ladderfix Safety
Base or Leveliser.
Do not use loose packing.
Slippery Ground. At angles around 1 in 4, normal exterior level surfaces even when wet
are not usually a problem, especially if rubber feet are used. But backward slopes, ice, oil,
moss and polish are dangerous. Clean up all slippery material under and around, not
forgetting that you also might slip stepping on and off.
Clean and inspect ladder feet regularly.
Soft Ground. When working on soft ground or flower beds, put down a stout board with a
suitable slip resistant surface.
Rungs and Footwear. Make sure that they are free of slippery material. Footwear should
have a proper arch to engage the rung. Soles should be substantial to avoid discomfort.
Toes should be reinforced.
Climbing. Have at least one hand free to hold on. If you are climbing “one handed” hold
the stile.
Overloading. Do not exceed limits or allow more than one person on at a time.
Handhold. Do not climb higher than 1 metre below the ladder top.
Overreaching. Do not allow both shoulders beyond one side of the ladder.
Caution.These safety guidelines are not an exhaustive list of precautions. They should
not be taken as a substitute for any additional measures found necessary on site, nor do
they guarantee that the use of a ladder is safe without regard to local conditions and are
always subject to an employers risk assessment.
