Important informationHAKI’s product liability and user´s manuals apply only to scaffolds that areentirely composed of components that have been made and supplied by HAKI.
HAKI’s type examination certifi cate apply only to scaffolds whose materials,dimensions and design accord with those specifi ed in the documentation uponwhich this certifi cate is based.
HAKI’s scaffold systems must not be erected using components of makes otherthan HAKI or be connected to scaffolds of makes other than HAKI. In such cases,a special study of load-bearing capacity must be carried out. However, HAKI hasno objection to the customary addition of scaffold tubes and approved couplersto the scaffold.
Adding components from different suppliers may invalidate the insurance cover.
HAKI reserves the right to make technical modifi cations on a continual basis.
A user’s manual should be provided to the user together with the scaffolding.
The latest versions of HAKI user’s manuals can be downloaded from our website,www.HAKI.com.

BASIC INFORMATION
HAKI Universal The modular scaffold has been type examined by SP Swedish NationalTest ing and Research Inst itute in accordance with Ordinance AFS 2013:4of the Swedish National Board of Occupational Safety and HealthCode of Statutes and SS-EN 12810-1 – Cert ificate No. 14 55 01 – for loadclasses 1 - 6 (0.75 - 6.0 kN/m2 ). The calculat ions were carried out using method 4026 of the SP TechnicalResearch Inst itute of Sweden.General The scaffolding has a bay width of 700, 770, 1050, 1250 or 1655 mm and a bay length of 3050 mm with a lift height of 2000 mm.Single tube beams and ledger beams can be used both as ledgers and transoms.HAKI decking units are suitable for use as decking. Components for the HAKI Universal system are hot-dip galvanized.Older components that are covered by the cert ificateLedger beam LB and Guardrail frame SKRD.
MarkingAll components, with the exception of locking catches , locking pins etc, come permanent ly marked with the HAKI logo and the last two figures of the year of manufacture ( S15). All loadbearing components are marked for full traceability. For further information, please refer to the HAKI Safety Guide.

Informat ion on safety when erect ing and dismant ling 1. Carry out local risk assessment and method statement. 2. Make sure that all lift ing equipment to be used, e.g chain hoists, lift ing ropes, pulley blocks, etc., has been thoroughly tested and approved by an authorised person in accordance with local regulat ions. 3. Check that tools and protect ive equipment are available at the worksite. 4. Wear appropriate personal safety equipment at all t imes, e.g. safety harnesses, proper independence lifelines with suitable fixings, etc. 5. When erect ing and dismant ling a scaffold, robust temporary decking must be used as temporary platforms for plat forms for the scaffolders. 6. Always make sure that the safety locking devices that prevent a plat form lift ing off have been act ivated once a platform has been installed. 7. Study all relevant instruct ions or safety direct ions from the manufacturers of the various scaffolds that are to be used. 8. Never climb up a scaffold from the outside. Always use the stairs, ladders or climbing frames that are designed to provide access to the upper decks from the inside of the scaffold. 9. If the scaffold is to be used outdoors, erect ion or dismant ling work must be discont inued of the weather condit ions are too bad. Make sure that all loose components are properly fixed before leaving the scaffold.10. Scaffolding work must be done by “competent operat ives” under the supervision of a “competent person”.11. Lift ing equipment must not be attached to a free-standing scaffold. 12. Beware of any overhead power lines nearby.13. Always observe and comply with the regulat ions issued by the local authorit ies concerned.
Instruct ions for dismant ling 1. Dismant le the scaffold from the topmost lift. 2. Start by taking down the toe boards. 3. Take down the topmost decking. 4. Take down the horizontals and diagonals of the topmost lift. 5. Finally remove the standards where possible. 6. Repeat 2-6 to take down the second topmost lift and continue the whole process unt il the dismant ling process reached the scaffold is completely dismant led. 7. Do not throw or drop materials to the ground. This may damage the material or cause personal injury. The materials must be lowered down to the ground by means of ropes or slings or passed down by hand. 8. If intermediate t ies or t ie rod tube have been installed, they must not be removed unt il the dismant ling process reaches the level in quest ion. 9. Always observe and comply with the regulat ions published by the local authorit ies concerned.10. Reference should also be made to the sect ion “Information on safety when erect ing and dismant ling” in this manual.
ERECTING/DISMANTLING SCAFFOLD

ERECTION PROCEDURE
Before commencing erect ion, ensure the ground condit ions are capable of carrying the loads to be imposed by the scaffold.Appropriate sole plates should be used. The user should refer to the relevant Code of Pract ise. Start the erect ion of the scaffold at the highest ground point or as directed by the scaffold lay-out plan.

Unless the scaffold is going to be crane lifted/suspended or used to support a temporary roof then the joints do not normally have to be pinned except when cantilevers are used. In this instance all joints above uppermost tie must be pinned. When selecting the standard size, be aware that to en-able the use of the Advanced Guard Rail method, you must always have at least 1m of outside standard above the next lift.
N.B It is not necessary to stagger the joints in the Standards.

Base jacksThe scaffolding is mounted on base jacks which are adjustable in height between 55 and 570mm.If more adjustments are needed, screw the base jacks down and assemble the beams to the next group of pockets. This means that the Standards can always be adjusted to ensure that the beams are horizontal. Standards Standards of length 3000mm or 2000mm are normally used in the scaffold.However 1500mm Standards may be used at the bottom of the scaffold in accordance with the alternat ive method of erect ion described on page 35.
Horizontals Generally, the scaffold is erected us-ing Ledgers and/or Ledger beams as ledgers and transoms with a height of 2000mm between the lifts. Each lift must be fitted horizontals on both the inside and the outside faces. The lower-most lift should always be installed at the lowest possible pocket level.
GuardrailsDecked lifts must be provided with guardrail frames or double guardrails and toeboards.The guardrail height must be aminimum of 950mm above decking level.

Bracing and tying-inVert ical diagonal bracing between the outside standards must be installed in every 5th bay and always in the end bays. Guard rail frames can replace vert ical diagonal braces, but MUST then be fitted in each bay and at every lift level, including the bottom level.Each inside standard must be t ied to the facade or equivalent at every 4th metre in height adjacent to the node between standard and beam.The lowest t ie must be fitted no more than 4.8 m above ground level.There must be t ies that can carry horizontal forces on at least every 6th pair of standards along the scaffold and at every level of t ies.In addit ion, we recommend that the scaffold always be anchored as high up as possible.Ties that can withstand horizontal forces should be dimensioned for a load of 5.5 kN parallel with the façade and 8.5 kN perpendicular to the façade. Other t ies should be dimensioned for a load of 4.6 kN perpendicular to the façade.Where a scaffold is covered insheet ing, the number of t ies must beincreased to take account of windload. Seperate calculat ions are therefore required.

Permissible construct ion heightsThe table applies to HAKI Universal with bay lengths 3.05 m, lift heights 2.0 m and a vert ical distance between t ies of 4.0 m.
Work must not be carried out on more than one lift at a t ime.
Other standard loads, bay lengths, bay widths and decking alternat ives will have an effect on the permissible construct ion height. Please contact HAKI’s technical department in these cases.
Loads from snow or ice are not included in the calculat ions.

Access waysAccess can be provided by means of a HAKI UTV stairway or a HAKI Stair Tower. Please refer to the Stair Tower user manual for further information.
Maintenance & storage
1. After use, all components must be thoroughly cleaned and inspected before storage.2. Any damaged parts or components found must be replaced.3. The manufacturer or supplier must be consulted before repairing scaffold material.4. Components must be sorted and stacked properly. Take care not to pile the stacks too high, so that the material lower down in the stacks becomes overloaded and damaged. If the material must be stacked up high, suitable racking and shelves should be used.5. Wooden and plast ic components (e.g. plat forms, toe boards, toe board holders, etc.) should be stored in a sheltered area so as to maximize their working life.
Wind, ice and snow
During the winter months, when extreme weather condit ions can occur, it is important to remove snow and ice immediately.With regards to wind loads, t ies must be installed every fourth metre in height; see the sect ion “Bracing and tying-in”. For clad scaffolding, calculat ions should be made in each individual case.For more information, please contact HAKI’s technical department.

LOADING CONDITION
Lattice beamsLatt ice beams 500/6100 are designed to allow the scaffold to cont inue to be erected across a span equivalent to two 3050 mm bays.Latt ice beams 500/6100 are fitted to the standards of the scaffold by hooking them into two pairs of pockets.The latt ice beams must be braced against lateral movement by fitt ing a ledger to the pair of pockets in the centre of the beams.
Permissible loads on lattice beams
Heavy Duty Beams
Aluminium lattice beamsAluminium latt ice beams are fitted in pairs on the inside and outside of the scaffold. Both the top and bottom tubes must be fixed to the standards using SW 48x48 double couplers or use latt ice beam connectors to standard. The height is adjust-ed so that the decking is level when this is fitted.The latt ice beams must be braced against lateral movement at least every other metre with the aid of a diagonally rigid framework of standards and beams or tubes and couplers.

Attachment points for personal fall protect ion equipmentThe only permissible points of attachment for personal fall protect ion equipment are as described below. Please note: Recommendations for points of attachment apply provided that the compo-nent in quest ion is otherwise without load and that only one person is attached to the same component at any one t ime.Components that have been subjected to loading from a fall must be replaced by new material.
Around a standard between two lifts oraround the lower tube in a ledger beam fi tted between two standards.Alternat ively, around a single-tube beam ofmaximum length 1964, fi tted between two standards.
Around a free standard, but only within 40cm of the node.
PLEASE NOTE: Not next to a standard joint.
No other points of attachments are recommended. Fall protect ion equipment MUST NOT be attached to the guardrails, brackets and cantilevers, i.e. beams fi xed only at one end. Fall protect ion equipment MUST NOT be attached to components that have not been locked into place.
PLEASE NOTE: Use only approved safety equipment.
