4) INSTALLATION
To put the poles into the snow, ice or ground, LISKI suggest to use a Ø 32 or 35 mm drill bit,
depending on the snow conditions.
Assemble the protection system putting the net into the 2 pole hooks; the hooks should be all at the
same height (1 at top, 1 at low of the pole), the lower hook should be forward down, the other one
forward up.
The groups of net, all of the same kind, should be attached and the “uphill”group should surmount
the “downhill”group, to avoid that the fallen skier can impact and pass through the only opening of
the net, at the joint by two net groups; do not align joints of net sections in the same direction of
impact of the skier.
The number of rows that must be placed depending by situation and by danger level, LISKI BC-130
NET can be placed in 1,2,3 or more rows; install the second row of net parallel to the first net, the
distance between the two nets should be as described in the set-up model.

5) AFTER USE
The inspection of LISKI BC-130 NET systems must be carried out before and after each use by
personnel who have received and reviewed all of the information contained in the present
document.
Maintain an updated logbook of the frequency of use of this product.
After use remove snow/ice from nets and support poles, align net to be re-wound in a straight line,
rotate the first support pole along the net to create a bundle and place the nets in the appropriate
transport/storage cradles.
Nets should be stored clean, dry and out of direct sunlight, and away from extreme heat and in a
well-ventilated warehouse. Nets should be kept off the floor and stored upright, on racks, to provide
ventilation underneath. It is better to store the nets vertically to allow drainage and prevent contact
of the fiber with the ground. Never store directly on a concrete, metal or dirt floor, and under no
circumstances should nets and/or acid and/or alkalis by kept in the same building. Product life will be
shortened by chemical and corrosive products or excessive temperatures.
