RILLING
Step 1: Incline the drill to get a slight (approx. 10˚) angle with poles pointing toward uphill.
These inclines are calculated in relation to an imaginary line running perpendicular to the
slope. All poles should be set in parallel and poles should not point downhill.
Step 2: Drill a hole (30 to 35 cm depth and 32mm diameter) in snow with a density range of
400-630 kg/m

.
WARNING
: If the snow depth or density is insufficient to provide sound anchorage of the
support poles, do not use these systems.
Step 3: Distance the support poles in order to obtain a net surface which is not overly tight
or overly loose.
Netting which is hung too tightly or too loose may not catch the skier who may ramp
up, flip out or slide under and be subjected to serious injury or even death.
