The images used in this manual are from the FasTival, but the set-up is similar for the Arko.

Step 1: Releasing safety cable

Roll the structure to the designated place (for this: unlock the brake of the wheels) and loosen the long safety cable (which is around the structure).

Step 2: First opening of the structure

Pull the structure open with 2 (or with 4) persons. Open the structure as far as you can, until the structure is half open in a stable position.

Step 3: Where to open the structure

Position the team of 4 people exactly like in this picture: two persons at each side, one person per joint, being the third joint starting from the sides. In your case there will be no membrane as on the picture.

Step 4: Full opening of the structure

Push the structure upwards with 4 people along the arch side: first push the structure up (at the starting joints) and then go to the lower joint next to you to pull the structure inwards. It’s a combination of keeping the center of the structure high enough and pulling the sides inwards. Again, there is no membrane in your case.
Keep in mind that you need a larger space to deploy and open the structure than the ultimate span of the structure in open state (in total 10m for the FasTival, a bit less for the Arko’s)!

Step 5: Connecting safety cable

Connect the safety cable between the two middle ground joints, at the eye bolts with the carabiner hooks. If the span of the structure is too big for the safety cable, you should push the sides of the structure more inwards, until the safety cable fits.

While someone is installing the safety cable, make sure that two other persons hold the structure in place so that it cannot close back down.

Step 6: Removing the wheels

Remove the wheels on the 4 ground joints.

Step 7: Installing the banners

Install the banners on the locations where necessary with the elastics provided.

Step 8: Installing the connection pieces

(if you want to connect a second structure, e.g. in the case of a FasTival L, otherwise skip this step)

First set up both structures separately and bring them as close together as possible. In the best scenario (first picture) the fins of the joints are (almost) touching each other. Sometimes this may not be possible (see second picture). Then attach the connection pieces by connecting the fins of the two joints concerned. For the FasTival, do this at 5 locations on the structure (so not at the level of the two ground joints).

Make sure you connect the pieces in the right way as shown in the picture.

Step 9: Attaching the locking cables

(if you want to remove the safety cable and/or if you expect high winds)

Attach all locking cables (at both sides of the structure). If they seem too short, then push the lower joint upwards to reduce the distance. Use a ladder where necessary.

Step 10: Installing the feet plates

Place the ground joints on the feet plates (there are 6 plates). One person should lift the structure a bit while the other one can install the footplate by positioning the joints over the holes. Move the joint to find a corresponding hole and fix it with the clevis bolt and pin.

If you have the version with the position pins, you can tighten the pins in the bolts. The ballast weights are placed over these position pins to block the lateral movement and position of the weights.

Step 11: Removing the safety cable

Only remove the safety cable when it hampers the passage underneath the structure. Only do this when the locking cables and the feet are secured!

Step 12: Installing ballast weights or anchors

Anchor the structure by putting the necessary ballast weights on the feet (when the structure is on hard underground). If the structure is on grass or soil, you can additionally use ground anchors through the big holes of the feet plates.
The total amount of ballast weight depends on the expected wind speed and extra loading of the structure: follow the instructions of the provided load bearing sheet.

Closing the structure

Step: Follow all the previous 12 steps in exact the opposite order

Make sure that the brake of the wheels are loose once you want to fold the structure back in its fully folded state.

DANGER: Be aware of the position of the hands! (from arch to half open)

Keep the hands at the outside to prevent them getting squeezed in between the beams when you close the structure from arch position to half open position.

DANGER: Be aware of the position of the hands! (from half open to fully closed)

Keep the hands at the outside of the top joints when closing the structure fully.
