General Information

The device has been manufactured in conformity with the TECHNICAL REGULATIONS listed below:
TECHNICAL SUPPORT INFORMATION
The PowerSeat is covered by a warranty, as laid down in the general conditions of sale. If during the warranty
period the device proves defective or suffers breakages, as indicated in the warranty, the manufacturer, after
checking the device, will repair or replace the defective components. You are reminded that modifications
carried out by the user, without explicit written authorisation from the manufacturer, will invalidate the
warranty and relieve the manufacturer of any responsibility for damage caused by the defective product. The
same considerations apply when spare parts that are not original or different from those explicitly indicated by
the manufacturer as “safety devices” are used. For all these reasons we advise customers to contact Harken
Technical Support.

GENERAL ADVICE
Use of the PowerSeat is restricted to qualified operators who are certified for temporary work at height with
the use of access and positioning systems using ropes according to the current regulations of the Nation in
which the device is used.
Harken is not responsible for damage caused by the PowerSeat to people, animals or property in the case of:
- use of the PowerSeat by operators without proper certification.
- improper use of the PowerSeat
- lack of proper maintenance, as indicated in the Maintenance chapter of this Manual
- unauthorised modifications or changes

INTENDED USE
IThe PowerSeat is designed to help qualified operators ascend a rope using the engine and descend using a
passive manual device. The PowerSeat is not safety equipment and is not a Personal Protective Equipment.
It must always be used in combination with a secondary rope to which is connected the fall arrest device fixed
to the operator’s harness by a cord with an energy absorber, and must satisfy the requirements of EN 363 on
individual systems for the protection against falling from heights.
Use the PowerSeat only in sufficiently ventilated areas, as the engine exhaust gases contain carbon monoxide.
In order to use the PowerSeat a risk analysis, and rescue plan must have been drawn up, as required by
current regulations of the nation where the device is used on temporary work at height and the use of access
and positioning systems using ropes.
The following guidelines must also be considered:
- ISO 22846: Personal equipment for protection against falls (Part 1/Part 2)
- IRATA: International Code of Practice.
- C(HSW)R: The Construction (Health, Safety and Welfare) Regulations.
- LOLER: The Lifting Operations and Lifting Equipment Regulations.
- MHSWR: The Management of Health and Safety at Work Regulations.
- PUWER: The Provision and Use of Work Equipment Regulations
This list is not complete and it is the responsibility of the qualified operator to be aware of current regulations
in his country on temporary work at height and the use of access and positioning systems using ropes or
other regulations relating to his specific sector of work.
