Dear customers,
dear operators,
with this playground equipment you have purchased a high quality product from company HUCK Seiltechnik which is used
Europe-wide by many well-known playground manufacturers.
If you assess defects at the swing basket, please contact your supplier or manufacturer immediately (phone: 0049 6443
8311-81 or -68, Fax: 0049 6443 8311-79 or e-mail: seiltechnik@huck.net).
Please always keep ready and specify: 1) serial number, 2) production date (month and year on green HUCK-seal at
upper end of suspension chains) and 3) control number (white number at black cover tube of rope wrapped ring).
If the swing basket will be installed at an existing swing frame, please pay attention to the utmost stability of the frame and
the swing joints. The frame has to bear up against extreme strains (centrifugal load approx. 1.5t). In case of doubt, consult a
competent person. Regarding installation and maintenance, basically the specifications of EN 1176 have to be considered.
In case of complete installation incl. swing frame, the installation- and maintenance-guides (incl. this supplement) have to be
taken into account.
Drilling holes for "bird's nest", art.no. 4650 at crossbeam:

Drilling holes for "honeycomb nest", art.no. 4550 at crossbeam and
Drilling holes for "Original-Mini-bird's nest", art.no. 4650-85 at crossbeam
clear distance for the inner swing joints 1.54m (drilling hole diam. 19mm)
clear distance for the outer safety joints 1.90m (drilling hole diam. 17mm)
In case of wooden swing frames, the joints will be additionally fixed with the spiked washer from the underside.
If using a metal swing frame, remove the spiked washer. Also the drilling holes at the underside have to be expanded to
take up the squared sockets of the bolts.
Checkup of swing joints during installation:
The free rotation of all swing joints is very important and has to be considered before installation on site. After assembly of
the swing basket, check if the bearing axis (main swing joint) is turning in case of minor swing movement. If this is not the
case, short and intensive circular translation can cause the failure of the suspension chains (wear through).
That problem can be avoided if the last upper chain link is fixed at first as tight as possible with the cross screw.
ATTENTION: this is the last cross screw which is carrying the chain (see drawing – pos.9). Never tighten or loose both
screws of the bearing axis – they are factory-aligned!
After that, the above stated checkup (only light swing movement of basket) has to be done. If the required effect is not
obtained, the hexagon screw has to be unscrewed for a ¼ rotation. The end of the screw has to be at least even with the
locking nut and additionally locked with a center punch.
The safety joints have to be checked regarding the free rotation, too. The adjusting has to be done in the same way:
unscrew the cross screw of the special steel shackle until the bow can rotate free and lock it with the pre-assembled locking
nut. The locking nut is used here as a counternut. The end of the screw must not be reached by the blue circlip (ring) of the
nut. Attention: the motion of rotation has to be in swing direction, too!
After start of operation, the maintenance work has to be done daily during the first week - afterwards once a week. Attention
should be paid especially to the bolted connection of swing frame and the solid fitting of the swing joints.
Depending on the utilization rate (latest every three months) all suspension points directly at the basket have to be checked
for chafe marks.
