The PDK is a powered machine.

The rated limits

The rated limits — maximum rider weight, total payload, rider height, clearance envelope, keep-clear zone, floor load and mounting, power supply, session length and operating environment — are stated in the Safety Manual supplied with your kit. Never operate outside them. The minimum rider age is also stated there.

7.1 Read first

The Product is a powered machine that moves the Rider in six axes with real force and speed. Misuse, incorrect assembly, poor mounting, modification, or ignoring the Safety Manual can cause serious injury or death to the Rider or bystanders. Before you assemble, install or operate the Product, read the Safety Manual and Installation Guide in full. They form part of the Terms; on a safety matter the Safety Manual prevails. The rated limits — maximum Rider weight, total payload, Rider height, clearance envelope, keep-clear zone, floor load and mounting, power supply, session length and operating environment — are stated in the Safety Manual. Never operate outside them.

7.2 Emergency stop

Before every session confirm it works and keep it within the Rider's reach and, when a second person is present, within that person's reach. Never disable, bypass, relocate out of reach or modify the emergency stop or any safety interlock.

7.3 Before every session

Check that all fasteners, mounts and anchors are tight; cables are secured and undamaged; the keep-clear zone is empty of people, pets and objects; the seat or cockpit is rated for motion use and secured as the Installation Guide requires; the emergency-stop test has passed; and the Rider meets 7.4.

7.4 Who must not ride

This list is not medical advice and is not complete. If in doubt, ask a doctor. Motion simulation can cause nausea, dizziness, disorientation and loss of balance during and after a session: start with short, low-intensity sessions and do not drive or do anything that needs balance until symptoms have passed.

7.5 Stop immediately

Stop immediately if the Rider feels unwell, dizzy or in pain; on any unusual noise, vibration or movement; if any part loosens; if the Software or Firmware shows a fault code; or if anyone enters the keep-clear zone.

7.6 Never

• modify or re-tune actuators, drives, controllers, wiring, the power supply or any safety interlock, or replace them with anything other than ARK-supplied or ARK-approved parts fitted as the Installation Guide or a Safety Notice instructs;
• modify, re-flash or bypass safety-critical Firmware;
• exceed the rated limits;
• operate with covers, guards or fasteners removed;
• fit a seat, cockpit or peripheral not rated for the loads it will carry;
• operate outdoors, on an unstable or unlevel floor, or in a wet environment;
• leave the Product powered and unattended with a Rider on board;
• let anyone into the keep-clear zone during operation.

7.7 Upkeep

Inspect fasteners, mounts, cables and actuators at the intervals in the Safety Manual and after any transport, impact, fault or unusual event; follow its maintenance schedule and replace wear items when it says so. Keep children, pets and bystanders out of the room or behind a barrier outside the keep-clear zone. Use only the supplied or approved power supply on a properly earthed outlet; do not use damaged cables; provide the ventilation the Installation Guide requires; keep flammable materials away from drives and power electronics.

7.8 Third-party games and platforms

The Product works with third-party sim titles, engines, telemetry APIs, plug-ins and PCs. We do not control them and are not responsible for their availability, compatibility, content, or the motion cues they send; flashing images come from them, and 7.4 applies. The compatibility list is on the support page.

7.9 Age

You must be at least 18, and at least the age of majority where you live, to buy a Product, hold an Account or accept the Terms. A minor may ride only if they are at least the minimum rider age and within the rated limits; a parent or legal guardian, or an adult authorised by one, is present and acts as Operator for the whole session, has read the Safety Manual, and has the emergency stop within reach. The Operator is responsible for supervising the minor.

7.10 Your acknowledgement

By buying, assembling, installing or operating a Product, or allowing anyone else to ride, you confirm that: (a) you have read and understood the Safety Manual and this Section; (b) you understand that motion simulation carries inherent risks of injury that cannot be fully removed even when the Product is used correctly; (c) you will follow the rated limits and the rules in this Section; (d) you will make sure every Rider and Operator you allow also knows and follows them; and (e) you are responsible for supervising the Riders you allow and for making sure they meet 7.4. This does not limit our liability for death or personal injury caused by our negligence, or by a defective Product, where the law says that liability cannot be limited (Terms, Section 13.1).

7.11 Safety Notices

If we learn of a safety issue we may issue a Safety Notice by email to your Account or order address, in the Software and on this website. It may require you to stop using the Product, install an update, inspect or replace a part, or return the Product. You must follow it. We bear the cost of anything a Safety Notice requires. If it requires you to stop using the Product and we cannot restore safe use within a reasonable time, we repair or replace the Product, or refund it, at our cost — at our option, or at your choice between at least two of those remedies where the law so provides; where the law allows, a refund of a Product you have had for more than a year may be reduced by a reasonable allowance for use. A Safety Notice supplements the Safety Manual; it does not change the commercial terms of your order.

Current Safety Notices: none issued.
