ensure that the rope is in good condition. Ensure
that the braking side of the rope has a stop knot
or other termination. The device may heat up
during descent and damage the rope: take care.
Safe operation of the device is dependent on the
condition of the rope–if the rope is damaged, it
must be replaced.
Harnesses
• NFPA 1983 use: Class II or Class III harnesses.
• ANSI Z359.4 use: ANSI Z359.11 full body harness
(sternal or ventral points).
Carabiners
Use only carabiners with locking gates.
• NFPA 1983 use: Technical or General Use carabiners.
• ANSI Z359.4 use: ANSI Z359.12 carabiners.
Anchors
• ANSI Z359.4 use: Anchors must comply with ANSI
Z359.4 and ANSI Z359.18.
6. WORKING PRINCIPLE
The CLUTCH allows the rope to be pulled through in one
direction, but friction of the rope on the Sheave in the other
direction causes the Sheave to lock, pivot, and capture the
rope between the Sheave and Friction Shoe. By holding
the braking side of the rope, the Brake Hand helps engage
the braking mechanism.
7. INSTALLATION /
RIGGING
Installing the Rope
1. Open the Side Plate by activating the Side Plate
Release Latch 2 times.
2. Move the Control Handle to the Standby position.
3. Load the rope according to the diagram marked
on the device.
4. Close the Side Plate and secure the device to
an appropriate attachment point or anchor with a
locking connector.
Loading the rope incorrectly
!
!
could cause imminent risk of
injury or death.
!
Usage on Anchor
In tight clearance or overhead rigging situations, an extra
carabiner is recommended to improve ergonomics, redirect
the rope and/or improve alignment of rope into the device.
An extra carabiner may also be used to increase friction on
the free end of the rope for heavy load applications.
Locking the Side Plate and Latch
If necessary, it is possible to lock the Side Plate and Latch
mechanism, after the rope is installed (i.e. when used
as a rescue kit). Install the Side Plate Lock Out Screw
(stored on the handle) into the Side Plate Lockout Screw
Hole in the Side Plate. Check that Side Plate and Latch
are secure.
8. FUNCTION TEST
Before each use, verify that the rope is correctly installed
and that the device is working properly. The CLUTCH must
be properly rigged prior to use. Always use a backup safety
system when performing this test.
1. Move the Control Handle to the Standby Position
and give a quick pull on the anchor/load side of
the rope. When rigged correctly the CLUTCH
will lock up.
2. Gradually apply a load to the device (rope taut,
handleinStandbyposition).Whilefirmlygripping
the braking side of the rope, gradually move the
Control Handle to Release Position to allow rope
through the device.
• Descent is possible = rope correctly
installed.
• Descent is not possible = check the installa-
tion of the rope.
3. When the Control Handle is released, the
CLUTCH should lock up and hold the rope.
4. Pull rope through the device as if using it to haul.
Audible clicking sound should be noticeable.
WARNING: DANGER OF DEATH. Do not
!
!
allow anything to interfere with the
operation of the device or its
components (Sheave, Control Handle,
!
22 CLUTCH USER MANUAL
etc.). Any constraint on the device may negate
the braking function.

10. PRECAUTIONS FOR
USE
WARNING: When lowering, the tail of the rope
should pass over the Friction Shoe, located adja-
cent to the Becket. Avoid placing the tail over the
Sideplate or over the back of the Chassis.

Heavy Loads/Expert Use Only - Max Loads
Forexpertusersspecificallytrainedinthisuse,the
CLUTCH can be used for loads up to 272 kg. These
operationsmustonlybeperformedbyrescuersspecifically
trained in these uses. For heavy loads, shock-loading must
absolutely be avoided. In these cases, users should take
cautionandalwaysmaintainafirmgriponthebraking

Heavy Loads, Expert Use Only - Descent/Lower
The CLUTCH can be used to descend and lower loads up
to 272 kg. When lowering heavy loads maintain a speed of
less than 0.5 m/s. An extra carabiner may also be used to
increase friction on the free end of the rope. When lowering
heavy loads from an overhead anchor it is recommended
to use a secondary friction carabiner.

When belaying heavy loads it is recommended to minimize
slack in the system.

To lower/descend, grip the braking side of the rope and
gradually pull on the Control Handle to adjust the descent
speed. To stop the descent let go of the Control Handle.
WARNING: when using multiple items of
equipment, make sure they are compatible. A
dangerous situation can arise in which the safety
function of an item of equipment can be affected
by the safety function of another item of equip-
ment. Be vigilant when working near sources of
electricity, moving machinery, abrasive or sharp
surfaces, or in an environment presenting chem-
ical or extreme temperature hazards. The energy
of descent is equal to the product of the descent
length, the mass of the load, the acceleration of
gravity, and the number of successive descents.
Any misuse of this equipment will introduce
additional dangers.

BELAYING
TheCLUTCHhasbeenthirdpartytestedandcertified
to meet the impact force and system extension require-
ments of NFPA 1983 (2017 ED) belay device (auxiliary
equipment).
Tensioned Belay of a Lowering System
Firmly grip the braking side of the rope and bring it back
toward the anchor, parallel to the load end. Use the Control
Handle to match the speed of the main line. If there is a
sudden change in speed or tension on the rope running
through the CLUTCH, the belayer must immediately let go
oftheControlHandle(disengage)whilemaintainingafirm
grip on the braking side of the rope to ensure the braking
mechanism activates and arrests the load in the shortest
distance possible.
WARNING: YOU MUST LET GO OF THE CON-
TROL HANDLE WHILE MAINTAINING A FIRM
GRIP ON THE BRAKING SIDE OF THE ROPE TO
ACTIVATE THE BELAY!
Slack belay
To facilitate feeding the rope, focus more on pushing the
rope into the device rather than pulling it out.
Belay of a Raising System
Simply pull the rope hand over hand through the device,
keepingafirmgriponthebrakingsideatalltimes.
15. HAULING
To build simple or compound mechanical advantage
systems, add an appropriate rope grab and traveling pulley
to the working rope, and if desired a second change of
direction pulley to the Becket of the CLUTCH.
