andtheamountofabrasionthelineexperiencesfromtheclimbingwall.Ata
minimum,thelineshouldbereplacedtwiceannually,orafter5,000climb/lower
cycles,whichevercomesrst.Theenclosedkitmayalsobeusedtoreplace

CAUTION
When replacing your Perfect Descent line, you should take specied
precautions to prevent the line from twisting inside the housing. You
should also ensure that when the line is detached at the joint, the free
end will not escape inside the housing under the force of the retracing
spring. Please read and understand all instructions provided BEFORE
you begin line replacement. Failure to follow specied precautions may
result in damage to the Perfect Descent and require factory service.

INSTRUCTIONS:
1. RemovethePerfectDescentfromtheclimbingwallandlayitonaat
surfacewiththefacelabeldown.Layasoftmaterialbeneaththeunitto

duringlineextraction,orhavesomeoneholdthePerfectDescenthandle
whilethelineisbeingextracted.
2. RemovethePhillipsheadscrew
locatednearthelinenozzle(Figure 2).
3. Notetheverticalorientationofthewebbingandnozzleslot.Itisimportant
thatthewebbingisnottwistedduringlineextraction.Pullthenozzlefrom
thehousingwithouttwisting(Figure 3)andextractallofthelinefromthe

4. Secure the line by inserting a
Phillips head screwdriver between
the two layers of blue webbing
where indicated in Figure 4.  To
prevent twisting it is important that
the webbing maintain its vertical
orientation (screwdriver oriented
vertically).  The screwdriver will
prevent the joint from returning into
the housing during replacement.
Release the webbing, making
certain that the line is adequately
secured, and that the screwdriver
will not slip loose or rotate.
Place some duct tape across the
screwdriver and housing nose to
prevent the screwdriver and line
from twisting (Figure 5).  If the
detachedendofthelineretractsand
islostwithinthehousing,thePerfect
Descent will require factory repair.
A black mark should appear on
the upper portion of the web
(Figure 6).  If not, the webbing
has become twisted.  Untwist the
webbing by carefully examining the
webbingasitexitsthehousingand
rotating the webbing so the mark
appearsinitsproperlocation.

7. Insertthenewthreadeddowelpininto
the loop formed by the blue webbing
(Figure 8).Alignthethreadedholewith
theholeinthebluewebbingloop.
8. Using the Allen wrench, secure
the new replacement line to
the blue webbing by running
the bolt through the hole in
the blue webbing, and into the
threaded dowel pin (Figure 9).
9. While tightening the bolt, ensure
thatthetwodowelpinsandtheblue
and black webbing loops remain
parallel(Figure 10).Realignthepins
ifnecessary.Makecertainthebolt
istight.Avoidexcessiveloosening
andre-tighteningofthebolt,asthis

10. Tieaknotloopapproximately12”downonthenewreplacementline.Grasp
thelineandpullittowardstheknotloopbehindthenozzle.Untwisttheportion
ofwebbingbetweenthenozzleandthescrewdriverthatsecuresthewebbing.
Check that the screwdriver is still vertical, and has not rotated during line
replacement.Ifso,reorientthescrewdrivertoitsoriginalposition.Alsocheck
thattheblackmarkisstillontheupperportionofwebbing.
13. Extract the line and untie the knot loop.  A second pair of hands will be
required tohelpsecurethewebbing. Return thenewlineinto thehousing
slowly, in a controlled manner, while maintaining a secure grip on the line.
14. Inspectpriortousebyextractingalloftheline,andreturningitonceagainto
thehousing.Checkforsmoothoperationandproperlineretraction.
11. With the nozzle slot oriented
vertically,andnotwistsintheline,
apply tension to the nozzle and
knotloopwhileremovingtheduct
tapeandscrewdriverthatsecured
thewebbing(Figure 11).Feedthe
linebackintothehousinguntilthe
nozzle and knot loop are against
thehousing.Pressthenozzleinto
thehousingsothatthenozzleslot
remains vertical, and the nozzle
screw hole is aligned with the
housingscrewhole.Againmake
certain that the webbing has not
twistedas thenozzle isinstalled.
12. Install the sheet metal screw
through the housing screw hole
and into the nozzle screw hole
(Figure 12).  Tighten the screw
untilsnug.Avoidover-tightening,
asyoumaystripthethreadsofthe

CAUTION
A twisted line will result in the line dragging on the housing, impeding
retraction. If you suspect that the line has become twisted during the
replacement process, remove the Perfect Descent from use until the
unit can be returned to an authorized service center for repair.
