The Duck is a non-aggressive device and during correct operational use it
will not damage ropes. In emergency deployment (see 'Deployment' section)
with the exception of very minor glazing a properly used Duck-R will lock on
to the Back-Up rope without causing serious damage to itself, its lanyard,
karabiners or to the Back-Up rope. The user is responsible for ensuring the
combination of all components in the rope access system do not adversely
affect the performance of any item with due regard to all user instructions.

DEPLOYMENT
The body of the Duck-R must NOT be squeezed or the
Cord pulled to de-weight a loaded or partially loaded
Duck-R.
Accidental Deployment
It is essential that all users are competent in the techniques
required to overcome accidental loading. If accidental
loading occurs during ascent, first check the ascent
equipment, then continue ascending until the Duck-R is no
longer under any loading. If loading occurs during descent,
first check the descent equipment, then use techniques to
complete a short ascent of the Working Rope until the
Duck- R is no longer under any loading. Any other
accidental loading should be assessed and appropriate
methods used to overcome the loading. At all times two
safety systems must be in place.
Emergency Deployment
If failure of the Working system e.g. Working Rope failure or
user detachment from the Working Rope, occurs and the
user becomes suspended on the Back-up Rope, the user
and work colleagues must consider the planned procedural
options available with regard to all factors of the actual
event.
These options may include amongst others:
I
. The deployment and use of a new Working Rope;
II
. The rescue by a colleague using new ropes;
III
. The use of the Back-up Rope to attach escape
equipment
(descender or ascenders) for the user to evacuate on the
single Back-up Rope;
IV
. Other techniques undertaken by competent persons.
All emergency actions should only be carried out following
a risk assessment of the situation. During emergency
deployment of the Back-up system any downward
movement of the user will be determined by several factors:
back-up rope stretch, cows-tail stretch, knot tightening and
device slippage. With the exception of very minor glazing a
properly used Duck-R will lock on to the Back-Up Rope
without causing any damage to itself, lanyard, karabiners
or the Back-Up Rope. Following any Emergency
Deployment all equipment must be removed from service
for inspection by a competent person.
WARNING
8
POSITIONING
At all times that the user is stationary the Duck-R should be
positioned as high as possible. The Duck-R must always be
above the descender or chest ascender and never below its
lanyard/cows-tail attachment point (FF1)
Ascent
To move the Duck-R up the rope, hold the lanyard or karabiner-
do not hold the device.
Descent:
The Duck-R backup device is fitted with a Positioning cord.
Users must always perform full function checks of both their
descent device and Duck-R before each descent.
To move the Duck-R down, pull the Positioning cord down using
the index finger and thumb. Users should only hold the
positioning cord for as short a period as necessary and ensure
that they are prepared to let go of the Positioning cord
immediately at all times.
In many applications the Duck-R should be controlled
independently of the descent device, in others it may be
necessary to control both Duck-R and descent device
simultaneously. It is the responsibility of the user to carry out a
risk assessment and determine which method is best for their
operational activity and environment.

WARNING
If users keep hold of Positioning Cord the device will not
function. Users must release their hold of the Cord
immediately if anything unexpected occurs. At all times check
the lanyard is not caught on obstacles and that it will not come
in to contact with sharp edges, heat, tools or any other source
of damage.

GENERAL INFORMATION
Rope Condition:
wear, wetness and contaminants will affect
the performance of the Duck-R. Some rope conditions will
make positioning of the Duck-R more difficult. Others e.g. oil &
grease will affect the device’s ability to perform - Back-Up may
not be provided. The effective operation of the Duck-R should
be monitored and checked in all conditions. Where any
performance doubt exists, the Duck-R should not be used.
Sea Water:
it is essential that this Duck-R is cleaned as soon as
practicable after each exposure to sea water or saline
environment.
Chemical reagent:
avoid contact with any substance or
material that may causes corrosion or other damage to the
device.If contact occurs consult expert advice as to damage
and cleaning requirements. Inspect prior to any re-use.
Maintenance:
the Duck-R is not user maintainable with the
exception of disinfection, cleaning and lubrication as detailed
below.
Disinfection:
following any contamination the source of the
contamination should be determined and advice obtained as to
suitable disinfecting procedure. After disinfection the device
should be re-cleaned. Sterilisation may be required.
Cleaning:
If soiled rinse in clean warm water of domestic
supply quality (maximum temperature 40°C) with mild
detergent at appropriate dilution (pH range 5.5 - 8.5). Dry
naturally away from direct heat sources. To remove grease use
a detergent that has properties that do not affect the metal
spring, body, cam or nylon cord.
Lubrication:
It is essential to maintain lubrication of the Cam
spring. Lubricate regularly and after cleaning with light machine
oil or teflon or silicone lubricant to ensue free movement of the
cam. Wipe off the excess to avoid contamination of ropes and
textile equip.
Lifespan:
it is very difficult to define the safe lifespan due to
varying use and storage conditions and may be as little as one
use, or even earlier if damaged (e.g. in transit or storage) prior
to first use. For the product to remain in service it must pass a
visual and tactile examination. Maximum lifespan: 10 years
from 1st use. Maximum Cam wear 1.5mm.
Obsolescence:
this device may become obsolete before the
end of its lifespan. Reasons for this may include changes in
applicable standards, regulations, legislation, development of
new techniques, incompatibility with other equipment etc.
Transportation & Storage:
after cleaning store unpacked in a
cool, dry, dark place in a chemically neutral environment away
from excessive heat or heat sources, high humidity, sharp
edges, corrosives or other possible causes of damage.
Do not store wet.

Wind
The effect of Wind can create additional
slack rope above the Duck-R, this must
be managed at all times. It may be
necessary to add friction to the Back-Up
Rope below the Duck-R or pull rope
through at work zones to partially load
the device.
Rope Obstacles
Great care is required if there are any
devices, knots or other obstacles
attached to the Back-Up Rope within 3m
b e l o w t h e D u c k - R . I n t h e s e
circumstances the Duck-R must be kept
as high as possible with less than 10cm
of slack in the lanyard or cows-tail until
the obstacle is dealt with.
ATTENTION TO WIND SPEED.

Move the device along the rope and check that it stays in position,
then with one hand holding the lanyard or cows-tail, pull down
vigorously to verify that the device locks on to the rope.
To maintain good spring action ensure that cam spring is
lubricated regularly. See section 16.

CLEARANCE DISTANCE
A d d i t i o n a l l y u n c o n t r o l l e d d o w n w a r d
movement will occur due to the elongation of
the Back-Up Rope during loading. This should
be assessed for the particular rope being used
but a minimum of 10% elongation should be
expected.
The amount of elongation will depend on
several factors including:
I. Elongation Properties of the particular rope
used;
II. Length of rope between the
Duck-R
and the
rope anchorage;
III. Knot tightening;
IV. Weight of user;
V. Amount of slack in
cows-tails/lanyards;
VI. All other factors that must be determined by
the user;
On long ropes the elongation will be many
meters.
Clearance
– The clearance distance must be
carefully assessed for all situations.
At work positions when the device is
positioned high and there is less than 10cm
slack in the Lanyard or Cows-tail there will be
very little slippage (e.g. a 100kg user less than
20cm). Additional slackness in the connecting
lanyard increase slippage.
