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

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..

USING THE DEVICE - CHECKING THE DEVICE BEFORE USE
Before and after every use, visually inspect the PowerSeat for traces of wear, damage or breakage. If such traces are
present, do not use the device. If the worn or defective parts are not immediately replaced, the manufacturer will
assume no responsibility for resulting damage or accidents.
In particular:
Check that the strop and carabiner are
intact.
Check the movement of the rope grab cover.
Check that the rope grab knob is working by
rotating the control lever and releasing it
(CLOSE JAW).
Check that the rope grab knob is working by
rotating the cotrol lever and releasing it
(OPEN JAW).
Inspect all screws and check that the marker on the screws and on the plate are aligned.
In case of any misaligned contact a HARKEN service center.

PowerSeat PWRS-G
WARNING!
Take at least two turns of the
rope around the winch drum,
and if it slips under load
increase the number of turns
to a maximum of four, taking
care not to overlap the rope.
7. Wind the rope clockwise around the winch
drum.
NOTE!
The number of turns needed round the winch drum depends on the load and the condition of the rope.
Check the device's descending capacity in its working configuration.
Before use ascend with the device, no more than 1 mtr (3,28 ft) and check, according to the descent procedure 1,
that it's descending smoothly.
In case of difficulties unwind the rope, and reduce the turns to not less than 2 wraps, until you have the optimal
configuration.
8. Pass the rope over the stripper arm. 9. Fit the rope into the rope grab. Raise the
cover to make this easier.
10. Position the rope inside the stopper. 11. Close the protective cover with the strap.

PowerSeat PWRS-G
USING THE DEVICE - PREPARING TO ASCEND
Install two ropes, Primary and Secondary, with separate anchorage points. Each rope must support at least 15
kN.
Install the Primary (or working) rope on the device as directed Primary Rope Installation Procedure above.
Attach the Secondary (or backup) rope is attached to the operator using a fall arrest device (EN353/2
approved) and energy absorber (EN355 approved).
Both ropes must be EN1891 Class A certified and have a diameter of between 10 (1/8" ) and 12.7 mm (1/2").
In the case of fault or breakage of the device or of the primary rope, the load will be immediately transferred
to the secondary rope through the fall arrest device, thus constituting the anti-fall system.
WARNING!
Do not use the PowerSeat in the case of illness, tiredness or if under the infl uence of drugs or alcohol.
WARNING!
Use the PowerSeat only with the primary and secondary ropes installed so as to create the anti-fall system
described above.
To use the PowerSeat the operator must also wear:
1. A full EN 361 and EN813 certified harness to which the device is attached at the lower front attachment and
the fall arrest device at the upper front attachment
2. An EN 795 B certified waist strop connected to the two side attachments of the harness and passing
outside the front tube of the PowerSeat
3. Appropriate Individual Personal Protective Equipment (PPE) (e.g. helmet, gloves, protective glasses and ear
plugs)
4. Suitable clothing, form fitting so it cannot catch on moving parts
