1 Safety First
1.1 Introduction
Read this instruction manual carefully.
Note that diagrams are for illustrative purposes only.
Instruction manuals are also available to download from our
website at zarges.com/uk.
PAXTower mobile aluminium towers are light-weight scaffold
towers used throughout the building and construction industry
for both indoor and outdoor access solutions where a stable
and secure platform is required. Ideal for maintenance and
installation work or short-term access, the highly versatile
towers provide a strong working platform for a variety of
heights.
This instruction manual provides you with step by step
instructions to ensure your system is erected easily and safely,
using the 3T (Through The Trapdoor) method. The law requires
that personnel erecting, dismantling or altering towers must
be competent. Any person erecting a mobile tower must have
a copy of this instruction manual. For further information
on the use of mobile access and working towers consult the
PASMA operators code of practice.
If you need further information, design advice, additional
instruction manuals or any other help with this product,
please contact the manufacturer on [phone] or
email [e-mail].
1.2 Compliances
The PAXTower 3T aluminium towers have been
tested and certified to EN 1004.
1.3 Preparation and inspection
Inspect the equipment before use to ensure that it is not
damaged and that it functions properly. Damaged or incorrect
components should not be used.

PAXTower 3T Instruction Manual4
2 Safe use
• Check that all components are onsite, undamaged and that
they are functioning correctly - (refer to Quantity Schedule,
page 10). Damaged or incorrect components should not be
used.
• Check if the ground on which the mobile access tower is to
be erected and moved is capable of supporting the tower.
• The safe working load is 208 kg for the one working platform
level, uniformly distributed.
• Any platform used as a working platform must be fitted with
toe boards.
• Towers must always be climbed from the inside during
assembly and use.
• Adjustable legs should only be used for levelling.
• This tower may be assembled by a single person, but it is
recommended that for 5.6 m PH a second person is used to
pass up components.
2.1 Lifting of equipment
• Tower components should be lifted using a reliable lifting
material (e.g. strong rope) employing a reliable knot (e.g.
clove hitch) to ensure safe fastening and always lift within
the footprint of the tower.
• Assembled mobile towers should not be lifted with a crane
or other lifting devices.
2.2 Stabilisers
• Stabilisers or outriggers should always be fitted when
specified. The Quantity Schedules show the recommended
stabilisation. In circumstances where there is restricted
ground clearance for stabilisers, contact the manufacturer.
2.3 Movement
The tower should only be moved by manual effort, and only
from the base.
• Beware of live electrical apparatus when moving the tower
(particularly overhead), plus wires or moving parts of
machinery.

5
• No person or materials should be on the tower during
movement.
• Caution should be exercised when wheeling a tower over
rough, uneven or sloping ground, taking care to unlock
and lock castors. If stabilisers are fitted, they should only
be lifted a maximum of 25mm above the ground to clear
ground obstructions.
• Before use, check that the tower is still correct and
complete.
• After every movement of the tower, use a spirit level to
check that it is vertical and level and set the adjustable legs
as required.
2.4 During use
• Effect of wind conditions on site must be considered before
assembly and during use.
• This structure has been assessed for windloads equating to
27mph (43kph,12m/s).
• If greater windspeeds are forecast the tower must be
dismantled while still safe to do so.

• Beware of open ended buildings, which can cause a
funnelling effect.
• Do not abuse equipment. Damaged or incorrect components
should not be used.
• Raising and lowering components, tools, and/or materials
by rope should be conducted within the lower base. Ensure
that the safe working load of the supporting decks and the
tower structure is not exceeded.
• The assembled tower is a working platform and should not
be used as a means of access or egress to other structures.
• Beware of horizontal forces (e.g. power tools) which could
generate instability. Maximum horizontal force: 30 kg.
• Do not use boxes or stepladders or other objects on the
platform to gain extra height.

PAXTower 3T Instruction Manual6
• After assembly the tower should be regularly inspected by a
competent person to ensure that no environmental changes
have occurred that may affect safe use.
2.5 Maintenance - storage - transport
• All components and their parts should be regularly
inspected to identify damage; particularly to joints. Lost
or broken parts should be replaced, and any tubing with
indentation greater than 5 mm should not be used and put
to one side for manufacture repair. Adjustable leg threads
should be cleaned and lightly lubricated to keep them free
running.
• Brace claws, frame interlock clips, trapdoor latches and
platform windlocks should be regularly checked to ensure
they lock correctly.
• Components should be stored with due care to prevent
damage.
• Ensure components are not damaged by excessive strapping
forces when transported.
• Danger of falling due to slippery tread surfaces!
Lubricating oil on tread surfaces causes falls and injuries.
Remove superfluous oil.
