5) CHECKS.
Further to the checks listed below, comply with what indicated in the general
instructions (paragraph 3).
Before each use, verify that: the size adjustment system can be securely fastened
and the adjustment bar slides freely through the crampon body; the buckle is
working properly; the heel lever adjustment screws turn without sticking; the wire
toe bails can rotate freely in their mounting holes; the points are well-sharpened
(for sharpening see the relative paragraph).
Attention!
During use check regularly
that the crampons are properly adjusted and well fastened to the boots.
Attention!
Even if the crampons are equipped with an anti-balling system, it is necessary to
be cautious and to pay attention to snow built-up under the crampons: danger of
slipping and falling.
6) ADJUSTMENT AND MOUNTING.
The crampons must fit perfectly onto the
boots that will be used.
Attention!
It is advisable to check the compatibility and
proper fitting of the crampons indoors before using them outdoors.
Attention!
The
Flex models are equipped with an adjustment bar, ideal for use with boots with
a semi-rigid sole.
Attention!
Please make sure that the adjustment bars that come
standard on the Snow Flex model are always correctly equipped with anti-wear
buckles. (Fig. 13). Adjusting the crampons is a two-stage process: the first is to the
broad size range 36÷43 or 42÷47 (macro-adjustment), the second is the adjust-
ment inside on of these broad size ranges (size adjustment).
Attention!
Some views
are simplified for a better understanding.
6.1 - Macro-adjustment.
There are two macro-adjustment systems:
• screw system (Ice): push the adjustment bar forwards, insert the shortening screw
into the square hole in the bar and screw on the auto-locking nut. Pull the bar rear-
wards until the shortening screw fits into the front half of the crampon. To return to
size range 42÷47 remove the shortening screw.
• rapid system (Hyper Spike, Lycan, Nuptse Evo): push the adjustment bar for-
wards, lifting it over the intermediate crossbar, and then pull it backwards so that
the end of the adjustment bar is stopped fro m moving further backwards by the
attachment to the crossbar (Fig. 4.3). To return to size range 42÷47 repeat the
operation in reverse.
6.2 - Size adjustment.
There are two size adjustment systems:
• single lever system (Ice, Nevis Flex, Snow Flex): lift the lever with your fingers and
move the bar to the desired position. Release the lever making sure that the locking
pin is correctly inserted into the hole of the bar (Fig. 4.1).
• double lever system (Hyper Spike, Lycan, Nuptse Evo): lift the command lever
so as to be able to lift the main lever and adjust the bar to the desired position.
Then release the command lever making sure that that the locking pin is correctly
inserted into the hole of the bar (Fig. 4.2).
Important!
The bar should not protrude
more than 10 mm (Fig. 4.6).
Important!
Check the fit of the rear crampon half to
the heel of the boot (Fig. 4.4-4.5).
6.3 - Additional adjustment.
For larger boots (size 44÷50) you can buy a longer
adjustment bar (LONG BAR / LONG FLEX BAR, LONG FLEX BAR-B), except for
the Nevis Flex and Snow Flex models that are sold with two adjustment bars of
different lengths (a short one for EU sizes 34÷41 and a long one for EU sizes
40÷47). For all crampons with SEMIAUTOMATIC or AUTOMATIC bindings ad-
just the height of the heel lever by loosening and then retightening the adjustment
screws, so that when it is snapped on the heel lever stays firmly in position (Fig.
4.7). For only the models Hyper Spike, Lycan, Nuptse Evo and Snow Flex with
AUTOMATIC bindings is it possible to adjust how much the front points stick out
by modifying which of the holes in the front half of the crampon the toe bail wire
is inserted into (Fig. 7).
6.4 - Fitting to the boot.
For all models there is a right foot and a left foot crampon
and they cannot be fitted to the other boot. Check the curve of the adjustment
bar and the binding strap with buckle is always on the outside of the foot (Fig.
6.1-6.2).
• CLASSIC binding (Fig. 5.1): put the toe of the boot into the toe binding; position
the heel of the boot onto the rear half of the crampon; thread the strap through the
rear binding, then through the front binding, then through the buckle and tighten
it. Remember to always pass the strap back through the second ring (Fig. 6.3).
• SEMIAUTOMATIC binding (Fig. 5.2): put the toe of the boot into the toe bind-
ing; Position the heel of the boot onto the rear half of he crampon; position the
heel lever on the rear welt of the boot and rotate it forwards until it snaps onto the
closed position; thread the strap through the front binding, then through the buckle
and tighten it. Remember to always pass the strap back through the second ring
(Fig. 6.3).
• Binding AUTOMATIC / A (mod. Hyper Spike / Lycan / Nuptse Evo - Fig. 5.3):
position the welt on the toe of the boot under the toe bail wire; position the heel of
the boot onto the rear half of he crampon; position the heel lever on the rear welt
of the boot and rotate it forwards until it snaps into the closed position; pass the
binding band around the upper part of the boot , then through the buckle and tight-
en it. Remember to always pass the strap back through the second ring (Fig. 6.3).
• Binding AUTOMATIC / B (Mod. Ice - Fig. 5.4): follow the instructions already
indicated for AUTOMATIC / A version, passing in this case the webbing binding
band through the eyelet of the tongue, connected to the front wire toe bail, as
illustrated.
• Binding AUTOMATIC / C (mod. Snow Flex - Fig. 5.5): position the welt on the
toe of the boot under the toe bail wire; position the heel of the boot onto the rear
half of he crampon; position the heel lever on the rear welt of the boot and rotate
it forwards until it snaps into the closed position; close the quick-release buckle and
pull the strap until tight.
6.5 - Test of function.
After having tightened the strap, check the crampon is fitted
correctly by kicking into the ice or snow: if the boot can be moved, remove it
from the crampon and readjust the fitting of the crampon.
Attention!
During use
check periodically that the crampon is firmly fitted to the boot, since during use the
binding can work loose.
6.6 - Hyper Spike.
The Hyper Spike model is equipped with a modular front sec-
tion, compatible with the main Hook point and with the Blade accessory point. The
Blade point, mounted to one side of laterally onto the Hook point, provides greater
stability on ice and mixed climbing. The possible combinations configurations are
shown in Fig. 9.5.
Attention!
The Blade accessory point must always be used
together with the main Hook point.
7) MAINTENANCE.
1) Always check before and during use that the crampons are
in good condition. 2) If the crampons are very heavily loaded or you are unsure
of their condition, replace them. 3) We recommend having the crampons checked
annually by a competent person (e.g. manufacturer). 4) If the points are worn,
sharpen them with a hand file: don’t use a powered grinder since the heat gen-
erated could affect the characteristics of the metal (steel or light alloy) and reduce
holding power (Fig. 8). For Hyper Spike and Lycan models do not file back to
beyond the first half of the first tooth.
Attention!
Maintain the thickness of the metal
or you may reduce the point’s holding power.
8) REPLACEMENT PARTS / ACCESSORIES.
The accessories / spare parts are
listed in the table (Fig. 9): antibots*; standard, long (Long Bar model) and/or
flexible (Flex Bar/Long Flex Bar models) regulation bars*; additional tips* for the
Hyper Spike model. The adjustment bars mounted on each model, if necessary,
can be replaced either with identical or compatible bars (Fig. 9.6). In case of re-
placement, it is necessary to keep track of the fabrication date marked on the origi-
nal bars, since it identifies the fabrication date of the whole product.
Attention!
The use of the flexible adjustment regulation bars is recommended with semi-rigid
and/or oversized boots (over 42 size), since they improve the comfort of use and
the life span of the crampons.
Attention!
Spare bars 4AST19 e 4AST20 include
two anti-wear buckles that can only be used with the Snow Flex model, never with
Nevis Flex crampons. (Fig. 13).
Attention!
Accessories/spare parts marked with
an asterisk (*) by themselves do not constitute PPE.
Attention!
Before installing an
accessory/replacement part, carefully read and understand the instructions for use
of the device on which it will be installed.
Attention!
Before use make sure that the
accessory/spare part is correctly installed.
