7B. Moving the CROLL down the rope (exceptional situation)
Move the CROLL a short distance up the rope and
simultaneously push down on the cam with the index finger
to disengage the teeth from the sheath of the rope. Do not
manipulate the trigger/safety catch because this creates a risk of
involuntary opening of the cam.

Diagram 7. Principles of operation
7A. Ascending
The CROLL is a device for ascending the work or access rope. It
grips the rope when loaded in a downward direction and slides
easily when moved up the rope.
The teeth push into the sheath of the rope, engaging the cam
and causing the device to jam on the rope. Slots in the cam
allow mud, etc. to be evacuated.

7C. Operational check
Before each use, to verify correct orientation on the rope
and functioning of the device, a test must always be
carried out with the user self-belayed.
Push the CROLL up the rope. It must slide easily up the
rope. Pull it down to verify it grips the rope.
7D. Precautions
- Close the CROLL’s cam when not in use because
equipment or other objects can become stuck in the
device if left open.
- ATTENTION, do not allow foreign objects to interfere
with the operation of the cam (pebbles, mud, vegetation,
cordage, slings, clothing, paint, etc.).
- BEWARE of catching the safety catch in clothing and
webbing.
- The rope between the CROLL and the anchor point
must always be taut. The user must always stay below
the anchor point of the rope.
- Shock-load absorption by the rope:
do not forget that it is the rope which absorbs energy in
the event of a fall. The closer you get to the anchor point,
the more the energy-absorbing capacity of the rope
diminishes, eventually becoming practically zero.
- Protect the rope from anything capable of damaging it
(e.g. sharp edge, rough surface, etc).
- The rope must be able to slide freely through the
CROLL. Beware of situations that can impede sliding
(e.g. knot or worn/damaged section in the rope, etc.).
- Do not forget to tie a stopper knot in the end of the
rope.
Diagram 8. Rope climbing
- Work rope: Use the CROLL and another hand rope
clamp (e.g. ASCENSION handled rope clamp) with a
foot-loop. Always attach yourself to the second ascender
with an appropriate lanyard.
- Safety rope: use a type A device.

Compatibility: attachment
points / connectors
An incompatible connection can cause
accidental disconnection, breakage,
or affect the safety function of another
piece of equipment.
WARNING, the attachment points of
your harness can act as a lever on the
gate of a connector.
When a sudden tension comes onto
the rope and/or an external pressure
on the locking system, and the
connector is poorly positioned, the
locking sleeve can break and the gate
can open itself.
To reduce this risk, check that your
connectors are properly positioned
each time the system is loaded
(lanyard, descender, etc.).
Also make sure your connectors are
compatible with the attachment points
(shape, size, etc.) by avoiding the use
of connectors showing a tendency to
position themselves incorrectly (and
stably) in the attachment points.
EN 365: WARNING
Compatibility
Check that this product is compatible
with the other components of your
equipment, see the instructions
specific to the products.
WARNING, when using multiple
pieces of equipment together, a
dangerous situation can result if
the safety function of one piece
of equipment is compromised by
the operation of another piece of
equipment.
Contact Petzl if you are uncertain
about the compatibility of your
equipment.
Anchors: Work at height
The anchor point of the system should
preferably be located above the user’s
position and must conform to the
requirements of the EN 795 standard,
in particular the minimum strength of
the anchor must be 10 kN.
Rescue plan
You must have a rescue plan and
the means to rapidly implement it in
case of difficulties encountered while
using this equipment. This implies
an adequate training in the necessary
rescue techniques.
Connectors
Carabiners must always be used
with the gate closed and locked.
Systematically verify the gate is closed
by pressing it with your hand.
Inspect the connectors as indicated in
their Instructions for use.
Various
- ATTENTION DANGER, do not allow
this product to rub against abrasive
materials or sharp edges.
- Users must be medically fit for
activities at height. WARNING, inert
suspension in a harness can result in
serious injury or death.
- You must check to ensure that the
product markings remain legible
during the entire lifetime of the
product.
- You must verify the suitability
of this equipment for use in your
application with regard to applicable
governmental regulations and other
standards on occupational safety.
- The instructions for use for each
item of equipment used in conjunction
with this product must be respected.
- The instructions for use must be
provided to users of this equipment.
If the equipment is re-sold outside
the original country of destination
the reseller shall provide these
instructions in the language of the
country in which the product is to
be used.
Lifetime
WARNING, an exceptional event can reduce the
lifetime of the product to one single use; for
example, if it is exposed to any of the following:
chemicals, extreme temperatures, sharp edges,
major fall or load, etc.
The potential lifetime of Petzl products is
as follows: up to 10 years from the date of
manufacture for plastic and textile products. It is
indefinite for metallic products.
The actual lifetime of a product ends when it
meets one of the retirement criteria listed below
(see “When to retire your equipment”), or when in
its system use it is judged obsolete.
The actual lifetime is influenced by a variety
of factors such as: the intensity, frequency,
and environment of use, the competence of
the user, how well the product is stored and
maintained, etc.
Inspect equipment periodically for
damage and/or deterioration.
In addition to the inspection before and during
use, a periodic in-depth inspection must be carried
out by a competent inspector at least once every
12 months. This inspection must be performed
at least once every 12 months. The frequency of
the in-depth inspection must be governed by the
type and the intensity of use. To keep better track
of your equipment, it is preferable to assign each
piece of equipment to a unique user so that he
will know its history. The results of inspections
should be documented in an «inspection record».
This document must allow recording of the
following details: type of equipment, model, name
and contact information of the manufacturer
or distributor, means of identification (serial or
individual number), year of manufacture, date
of purchase, date of first use, name of user,
all other pertinent information for example
maintenance and frequency of use, the history of
periodic inspections (date / comments and noted
problems / name and signature of the competent
person who performed the inspection / anticipated
date of next inspection). See example of detailed
inspection record and other informational tools
available at www.petzl.com/ppe
When to retire your equipment
Immediately retire any equipment if:
- it fails to pass inspection (inspection before and
during use and the periodic in-depth inspection),
- it has been subjected to a major fall or load,
- you do not know its full usage history,
- it is at least 10 years old and made of plastics
or textiles,
- you have any doubt as to its integrity.
Destroy retired equipment to prevent further use.
Product obsolescence
There are many reasons why a product may be
judged obsolete and thus retired before the end of
its actual lifetime. Examples include: changes in
applicable standards, regulations, or legislation;
development of new techniques, incompatibility
with other equipment, etc.
Modifications, repairs
Any modification, addition to, or repair of the
equipment other than that authorized by Petzl
is prohibited: due to the risk of reducing the
effectiveness of the equipment.
Storage, transport
Keep your harness in a bag or other container to
protect it from exposure to UV, moisture, chemical
products, etc.
Guarantee
This product is guaranteed for 3 years against
any faults in materials or manufacture. Exclusions
from the guarantee: normal wear and tear,
oxidation, modifications or alterations, incorrect
storage, poor maintenance, damage due to
accidents, to negligence, or to improper or
incorrect usage.
PETZL is not responsible for the consequences,
direct, indirect or accidental, or any other type of
damage befalling or resulting from the use of its
