Ground quality
With regard to the type of ground in the play area,
please refer to EN 1176-1. According to this, sand,
wood chips, gravel and HIC-tested synthetic
protective surfaces are permitted. We recommend a
covering of gravel at least 400 mm thick (grain size
2–8 mm) or sand (grain size 0.2–2 mm). If you use a
synthetic protective surfaces it must be sure that all
relevant parts for the maintenance (see maintenance
instruction on page 5 and 6) are every time
accessibly. If necessary consult SMB.

Assembly
General advice
The rope netting has been knotting by a hercules rope (an steel wire rope, which is coated with chemical
fibre). This coating could become damaged, if you move the rope over the ground. Please work carefully.
Spread out rope netting
The rope netting has been folded up following knotting in the factory. Take the netting out of the container
in accordance with the folds. The netting should be spread out in a triangular shape with the base of the
triangle lying in the diagonals of the foundations. The tip of the netting can be recognised by the
aluminium mast cap and should be lined up with foundation 3 (see schematic diagram). The
connection with foundations 1 and 2should now be created, using the tension jacks to connect the
netting to the tension rods of the foundations.
Insert the mast into the netting
Push the mast through the netting to the tip of the net. A hemp rope is attached to the netting as a guide
when threading though. Once the mast has been threaded through, place the mast cap in the mast, raise
the mast slightly by lifting it and support it temporarily on the tip. In this position, it should be ensured that
the mast supports itself on the round plate of the mast plate.
Raising the mast
When raising the mast it is essential to ensure that you pull the mast, not the net. To raise the mast, use a
cable pull (10 KN tensile force). The mast, including the netting, should be raised carefully. In particular, it
should be ensured that the mast plate is in the mast tube and is not pulled out and that the foot of the
mast is pulled onto the round plate. Once the mast has been raised higher than 45°, the connection
between the netting and foundation 3 is created. The mast should be raised higher until it is in a vertical
position. The final connection with foundation 4 is now created. Pulling the netting to the tension rods is
made easier with the aid of a crowbar, which should be placed in the curved clevis, as a result of the lever
action. Do not pull the mast with the cable pull over and above the vertical in the direction of the
tension rods (see figure 3).

Fitting netting entry points
The entry ladders (if ordered) should be fitted on the space netting at the press connections marked (if
not already done in the works) and on the middle base on the eye bolts (Figure B).
Tensioning the netting
Tensioning (tensioning tools are supplied) is carried out with the tube tensioning jacks and should be performed
uniformly and crossways. Alternating at each turnbuckle in each case a short piece must become strained
till the final initial tension is achieved. Ensure that the mast is in a vertical position. Apply noticeable
preliminary tension to the rope netting. After tensioning, the lock nut should be securely tightened. Finally,
the safety ropes should be connected to the safety anchor loop via the clevises.
The first re-tensioning of the space netting
!!! Initial re-tensioning should be carried out after one to two weeks of use
(reference operational inspection for more details) !!!
Caution:
When putting the mast up and when
stretching the space network make
sure absolutely that the mast is not
pulled beyond the vertical (figure 3)!
Pull only at the mast, not at the space
net (Figure 3)!

Maintenance instructions EN 1176-1
Visual routine inspection
Frequency will be based on local conditions (high/low use, vandalism, air pollution, effects of weather).
The inspection must be carried out by an expert or specialist company.
Check Space Net for general damage, wear and tear and damage resulting from vandalism
Check ground quality (layer of sand = protection from a fall; contamination of sand = protection from
injury)
Operational inspection (twice-yearly)
The entire Space Net should be checked for damage, particularly for breaks in the wires
On the mast cap, it should be checked that the central markings on the mast rope are between the
rope shackles
All the anchoring cables should be checked:
The lock nuts should be tightened securely to the tension jacks!
The safety ropes should be connected to the thinner traction anchor loop via the clevis
connection.
Check the preliminary tension of the Space Net and adjust tension if necessary.
Adjusting tension (see picture on page 6):
Uncover the tension lock and clean the threaded parts
Remove the lock nut
Adjust tension with the tensioning spanner SW 46 supplied
Tensioning should be carried out until it is no longer possible to tighten the tensioning spanner
manually without any great strain. When tensioning, the direction of rotation for tensioning should be
counteracted so that the inclined tension cables do not become twisted.
It should be ensured that the mast is vertical.
Fasten the lock nut again securely

Main inspection (annually)
In addition to the checks in the visual and operational inspection:
Check the clevis connections: curved clevis on the inclined tension cable, straight clevis on the
tension anchor loop.
Check the safety cable for damage
Check the tension anchor in the foundations for signs of corrosion
Check that the mast plate is positioned stably on the foundation and check for signs of corrosion
Check the foundations for possible cracks in the concrete. To do this, the foundations should be
exposed in the area of the tensioning anchors.
Please note: The swaying of the mast tube is a static necessity and is therefore intentional.
In order to guarantee enjoyment when playing and a long life, the rope Space Net should be kept under
tension. The first tension adjustment should be carried out approximately one week after the first use.
Further tension adjustments will be necessary at longer intervals, depending on the loss of elasticity of
the ropes, until the natural stretch capacity of the rope has been exhausted.
