Nomenclature of parts
(1) moving side-piece, (2) safety catch, (3) friction runner,
(4) side-piece pivot, (5) cam, (6) anti-error catch, (7) fi xed
side-piece, (8) handle. Principal materials: aluminum alloy
(side-pieces), stainless steel (cam), chrome-plated steel
(anti-error catch).
Checking, points to verify
Check before each use: the fi xed and moving side-pieces;
the cam (check the wear indicator*- see drawing) and the
friction runner; the locking components (safety catch, side-
piece pivot), and the operation of the springs i n the cam, the
safety catch, and the anti-error catch. Finally, carry out the
operational check (see diagram 2).
* Warning, when the cam groove becomes worn all the
way to the wear indicator, discontinue use of the I'D.
Depending on the rope diameter and condition of the sheath,
the descender may not possess suffi cient braking power.
If in any doubt, return the device to PETZL for checking.
Instructions for use
This device can help prevent some errors, but not all of
them. The user must receive specifi c training and always
remain alert. The use of gloves is strongly recommended.
Always tie a knot in the end of the rope.
Positions of the handle
(a) transport, (b) work positioning, (c) descent and belaying,
(d) panic locking.
Diagram 1. Installation of the rope
Attach the I'D either to the harness (A) (device is moving),
or to the anchor (B) (device is fi xed). Open the moving
side-piece. Insert the rope as indicated by the engraving
on the device. The handle must be in position (c).
Close the moving side-piece (security catch) on a locked
carabiner.
Diagram 2. Operational check
Before each use, to check the correct installation
of the rope and correct operation of the device, a
test must always be carried out while self-belayed.
(A) Moving device: before descending, transfer bodyweight
onto the device, rope taut, (handle in position c).
Check that the device locks onto the rope. Holding the free
end of the rope in one hand, pull progressively on the handle
with the other, allowing the rope to run. When the handle is
released, the I'D brakes, then locks onto the rope. If the I'D
does not lock, or if descent is not possible due to
the device remaining locked whatever is done to the
handle, check that the rope is correctly installed. With
bodyweight still on the device, check the operation
of the panic lock by pulling hard on the handle
(position d): the device brakes then locks onto the rope.
(B) Fixed device (use for belaying or evacuation): when
the rope from the second or the load is strongly pulled
(handle in position c), the device must lock onto the rope.
Warning, in the case of an error (rope threaded backwards)
the anti-error catch will not work. With the device under
load, check the operation of the panic lock by pushing hard
on the handle (position d) : the device brakes, then locks
onto the rope.
Diagram 3. Descent
Moving device (position c), installed on the harness:
braking control is effected by loosening or tightening
the grip on the free end of the rope, while unlocking
the rope by pulling the handle with the other hand.
Locking is achieved simply by releasing the handle. In a
panic situation: if the handle is pulled too much (position
d) the device brakes, then locks onto the rope. To continue
the descent, fi rst move the handle upwards (position c).
Warning, if the I'D is held in a horizontal position by the
hand, the braking function can be rendered inoperative.
For extra braking friction, pass the free end of the
rope through a carabiner.
Warning, this extra friction carabiner can lock the I'D
into a horizontal position and render the braking function
inoperative.
Diagram 4. Work positioning
After having stopped at the desired position, to lock the
device onto the rope, turn the handle in the opposite
direction to that of the descent, then pull it down as far as
possible without forcing it (position b); this position varies
according to the diameter of the rope. For work positioning
(both hands off of the rope), the I'D must be set in this
position. To unlock the system, hold the free end of the rope
5 Notice I'D D20 réf. : D20900-04
in one hand, and with the other return the handle to the
descent position.
Diagram 5. Occasional rope climbing
Moving device (position c or d), installed on the harness.
The required movements are as follows:
- hang from the I'D,
- Slide the handled rope clamp/grab ASCENSION (B17) up
the rope, while lifting the foot in the footloop (this rope
clamp / grab must be attached to the harness by a lanyard).
- stand up in the footloop attached to
the rope clamp/grab (B17) while pulling the slack
rope through the device (never allow slack to develop
in the rope),
- hang once again from the I'D,
- move up the rope clamp/grab (B17) once again, and so
on.
Diagram 6. Lowering from a fi xed anchor-
point
The device is attached to the anchor: the free end of the rope
must pass through a carabiner for extra braking friction.
Hold this free end and push the handle upwards (position c)
to unlock the device.
Diagram 7. Lowering from the harness
The device is attached to the harness. To lower a person,
attach yourself to a secure anchor, then brace yourself in
a stable position and use a supplementary braking system.
The device is then used in a manner similar to that shown
in diagram 3.
Diagram 8. Evacuation in exceptional
circumstances: accompanied descent
Moving device, attached to the harness: must only
be used by rescuers trained in this technique.
Maxi 250 kg, no impact loading tolerated, must be used with
a supplementary braking system.
Belaying
Pay attention to the safety of the belayer: it is absolutely
necessary that he/she be belayed so as to avoid any risk
of a fall. Slow falls and lightweight climbers: numerous
rubbing-points over a long length of rope can reduce the
transmission of impact force onto the device. This can delay
the braking action on the rope.
Diagram 9. Belaying the leader
Use a dynamic rope certifi ed to EN 892. The device is
attached (position c) to the second's harness (check that
the rope is properly inserted before use): the belayer holds
the free end of the rope with one hand, and the leader's
rope with the other. For easier running of the rope, it
is more important to push the free end into the device,
rather than to pull the rope through from the leader's side.
To stop a fall, pull fi rmly on the free end. To lower, use the
device in a manner similar to that shown in diagram 7.
Diagram 10. Belaying the second / Self-
belaying
The device is attached (position c) to the anchor: with one
hand, the belayer holds the free end of the rope, and with
the other, the rope to the second. Take in the rope regularly.
To stop a fall, pull fi rmly on the free end of the rope. To
lower, use the device in a manner similar to that shown in
diagram 6. Warning, in the case of an error (rope incorrectly
installed), the anti-error catch will not work with the I'D in
this position.
Diagram 11. Anti-return lifting point +
simple hauling system
The device is attached (position c) to the anchor: the I'D
can be used as an anti-return point to tension a rope or to
lift a load.

Checking = safety
Do not hesitate to scrap a product showing signs of
wear which might affect its strength, or restrict its
operation. For your safety we advise you to adopt
a 3-level checking schedule:
- before and after each use it is necessary to check the
condition of the product,
- during use, it is important to regularly monitor the
condition of the product and of its connections to the other
elements of the system.
- Periodically, a more thorough inspection must be carried
out by a competent inspector: approximately every three
months for textile products and helmets, approximately
annually for metallic products.
For more safety and better control of your equipment, we
advise you to keep an inspection record for each product.
It is preferable to personally issue each user of P.P.E. with
his or her own set of equipment.
Major fall and impact
Do not continue to use this product after a major fall or a
major impact (fall of the product or impact on the product).
Even though no external signs may be visible, a deformation
may restrict its operation or internal damage may have
occurred, thus reducing its strength. Do not hesitate to
contact PETZL in case of doubt.
Lifetime = shelf life + useful life
Shelf life (in favorable conditions):
Helmets, harnesses, webbing slings and lanyards: 5 years
Metallic products: no limitation.
- The useful life depends on the intensity and the
environment of usage. Certain environmental elements
will considerably accelerate wear: salt, sand, snow, ice,
moisture, chemicals. In exceptional circumstances, wear
or damage could occur on the fi rst use which reduces
the lifetime of the product to that one single use.
Maximum useful life: helmets, harnesses: 5 years;
slings, lanyards: 3 years;
metallic products: no limitation.
For webbing, slings, and lanyards, because of their direct
contact with supporting structures and the heavy demands
that usage places on them, their average operational lifetime
is 6 months heavy use, 12 months normal use, 3 years
maximum occasional use.
