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

- use of spare parts that are not original or specific for the model

- total or partial failure to observe the instructions

- usage contrary to specific national regulations

For safety information on the use of the engine, consult the Engine Manual supplied together with this Manual

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.

General Information

WARNING!

read the instructions in this manual attentively and carefully follow the indications it contains before using the PowerSeat

Safety Precautions

IMPROPER USE

The machine must not be used:

- for purposes different from those outlined in “Intended use” chapter, or for purposes not mentioned in this manual or different from those mentioned

- if unauthorised modifications or interventions have been carried out

- in an explosive atmosphere

- after it has fallen from a height of more than 1mtr onto a hard surface. In this case the device must be returned to the manufacturer or to a Harken authorised repair centre.

SAFETY DEVICES

The following safety devices are installed:

- Fall arrest attachment consists of strap and carabiner locked to the main support plate certified according to EN 1275; EN 362 Standards.

- Plastic cover on the central support for protecting the device from contact shocks and rope jamming

- Shaped plastic guard between the descending knob and the rope entry on the winch to prevent the rope jamming and tangling.

PERSONAL PROTECTIVE EQUIPMENT (PPE)

The device bears an adhesive label reminding you of the obligation:

- to use gloves

- to use ear plugs or ear muffs

PowerSeat PWRS-G

DEVICE DESCRIPTION - GENERAL

The PowerSeat is designed to help qualified operators ascend a rope and descend using a passive manual device.

The rope must be inserted in its housing in the vertical tube, through the deflector sheave, wrapped round the winch drum and locked in the rope grab.

When the engine is started, a transmission system rotates the drum and creates a traction force on the rope.

The engine is 4-stroke internal combustion and supplies the power for ascending, it has a pull start with automatic rewind and double action mechanical controls. Switch off is electrical.

During descent the engine is switched off and the operator uses the lever to open the rope grab and allow the rope to slide round the drum in a controlled descent..
