ICE SCREW S/M/L SPECIFIC INSTRUCTIONS
This note contains the necessary information for a correct use of the following
product/s: ice screws for mountaineering and ice climbing.
1) FIELD OF APPLICATION.
The ice screws are available in three distinct lengths, suitable for different types
of use.
1.1 - Ice screw M/L.
Ice Screw M and L models constitute Personal Protective
Equipment (P.P.E.) for the protection against falls from a height. They comply with
Regulation (EU) 2016/425 and they are certified to EN 568:2015 standard
(Mountaineering equipment / Ice anchors).
1.2 - Ice screw S.
Ice Screw S model is an ice screw intended for progression
only. Due to a body that is only 10 cm long, this ice screw offers a holding
strength that is lower than the requirements established by the EN 568 standard
(10 kN) when pull-out tested. For this reason, this screw does not constitute a Per-
sonal Protective Equipment (P.P.E.) and it should only be used when the thickness
of the ice does not allow the use of the certified models (Ice Screw M/L).
2) NOTIFIED BODIES.
Refer to the legend in the general instructions (paragraph 9
/ table D): M6; N1.
Caution!

2.4): 1.
4) MARKING
.
Numbers/letters without caption: refer to the legend in the general instructions
(paragraph 5).
4.1 - General
(Fig. 3). Ice Screw M-L: 2; 4; 6; 7; 11; 12; 30) Minimum guaran-
teed pull-out strength. Ice Screw S: 2; 4; 7; 31) Warning stating that the product
does not constitute Personal Protective Equipment (P.P.E.).
4.2 - Traceability
(Fig. 3)
.
Indications:T3; T8.
5) COMPATIBILITY.
The product can only be used in combination with CE-marked equipment, moun-
taineering equipment such as connectors (EN 12275), harnesses (EN 12277)
ropes (EN 892), sling (EN 566), etc.
6) CHECKS.
In addition to the checks described below, do comply with the directions provided
in the general instructions (paragraph 3). Before each use, check thread and end
teeth for wear and tear. If the end teeth are worn out, re-sharpen them by using
a hand file, making sure the original angles are preserved.
Caution!
Never use
a grinding wheel, as it would excessively heat the material of the screw, compro-
mising its mechanical properties and strength.
6) ISTRUCTIONS FOR USE.
7.1 - Installation.
Remove any brittle crust from the surface of the ice (Fig. 4.1).
Place the ice screw at an angle of 90° to the surface (Fig. 4.2). While applying
some pressure, rotate the screw in a clockwise direction until the thread engages
(Fig. 4.3). Keep rotating until the screw is fully inserted (Fig. 4.4). If a complete in-
sertion is not possible, make sure that the ice screw does not excessively protrude
above the surface (Fig. 4.6) and that it does not go into contact with the rock
below the ice (Fig. 4.10). In this case, it is possible to secure a Dyneema sling
to the tube of the screw (Fig. 4.8) avoiding, however, to install it over its thread.
7.2 - Removal.
To remove the screw from the ice, turn the screw in an anti-clock-
wise direction. If unscrewing is difficult, use the pick of the ice axe for some
leverage. Once it has been removed, immediately extract the ice core to avoid
it from freezing inside the screw.
Caution!
To extract the ice core, if necessary,
tap the screw on the ice surface, as shown (Fig. 4.11).
Caution!
Do not hit the
thread (Fig. 4.12).
7.3 - Warnings.
1) The reliability and strength of the ice screws is determined
by the conditions of the medium they are used on: avoid using them on aerated,
fractured or very thin ice. 2) A sudden reduction of the force needed to turn the
screw in, indicates the presence of an air pocket inside the ice (Fig. 4.9): in these
cases it is essential to change the position of the ice screw placement.
8) MAINTENANCE.
To properly preserve the equipment it is advisable to: after each use, pass a rag
soaked in oil over the surface of the equipment or use some silicone spray to
prevent it from rusting and make it easier to remove from the ice when used in very
cold environments; when not in use, preserve teeth and thread using the specific
protectors that are supplied with the product.
