LIFACombiCleaner15/40isapneumatically
operatedductcleaningmachinefordemanding
cleaningtasksinroundandrectangularventila-
tionducts.LIFACombiCleanersaredesignedfor
thecleaningofsmall,mediumandlargeducts.
ThenameCombiCleanerstatesthatitiscom-
binedwithbrushingandthepossibilityofspray-
ingliquidsorcompressedairwhilebrushing.
BothLIFACombiCleanerbrushingmachinescan
beusedingreaseductcleaning.Thelengthof
thecleaningshaftis15meters(50ft.,CC15)or
40meters(131ft.,CC40)orsotheycanbeused
incleaningupto25m(82ft.,CC15)or75m

Theuseofcompressedairgivesanalternative
toLIFA’selectricallyoperatedandhydraulic
machines.
Acentering devicefortheshaftisavailableasanaccessoryfortheLIFACombiCleanerbrushing
machines.Thecenteringdevicehelps to push the brush in the ductandcentres the brushinthe

Thefollowingsafetydirectionsmustbecarefullyobservedinordertoavoid
injurytopersonnelordamagetotheenvironmentortotheLIFACombiCleaner
brushingmachineitself.Followingtheseinstructionswillensurethesafeand
uninterrupteduseofthemachine.
Safety Precautions
• Theequipmentmustnotbepositionedoruseinplaceswherethere
isariskofexplosionorhazardoussubstances.
• Theequipmentmustnotgetwetanditmustbeprotectedfrom
moisture,vibrationandwind.
• Foreignobjectsmustnotbeinsertedorttedintotheequipment.
• Themachinecannotbecoveredduringtheuse.
• Theusermustensurethattheapplianceisadjustedforthetaskand
thatthestatutoryrequirementsaremet.
1. Avoid contamination of the
environment
Themachinemustbekeptascleanas
possible.Theshaftmustbecleaned
beforepushingitbacktothemachine.
Thebrushesandtheshellofthe
cleaningshaftmustbecleanedafter
theworkhasbeencompleted,before
transportingthemachinetoanother
location.
2. General safety
Thecompressedairhosemustbe
disconnectedwhenthemachineisnot
beingused.Itisforbiddentomake
anymodicationstothebrushing
machineortheaccessories(for
examplebrushes).
3. Operator safety
Theperson/personsperformingthework
mustusepersonalprotectiveequipment:
lteredmouthmask,helmet,earmuffs,
safetygoggles,overallwithlongsleeves,
protectionshoesandothernecessary
protectiveequipmentthatthetaskathand
requires.
LIFACombiCleanerbrushingmachines
haveastrongrotatingforce.Clothesor
haircaneasilygetcaughtinthebrushand
causedamageoraccidents.The brush
must always be placed in the ventilation
duct before switching on the machine.
Themachinecannotbeusedwhenthe
brushisoutsidetheventilationduct.
Becauseofthegreatrotatingforce,the

7. Noise level
ThenoiselevelofLIFACombiCleaneris
low(<70dB)anditisnotdependantof
theoperatingenvironment.
8. Transportation and operating position
Duringthetransportation,themachine

Operating Principles

Beforebeginningthework,checktheductworkwitha)LIFADuctControl(accessory)
equipmentandchoosethesuitableb) brushesandnozzlesbasedonthesizeand
constructionoftheductaswellasthecompositionoftheremovabledirt.
• Before beginning the work, check
the ductworkwithLIFADuctControl
(accessory)camerainspection
equipment.Theremaybeairvolume
controllers,noisesilencers,re
dampersetc.thatcanbedamaged
duringthework.
• Inlargerectangularducts,theremight
besupporterpolesinsidetheduct.
Useextracare,whendealingwith
ductsequippedwithsupporters.When
cleaninglarge rectangular or round
ductstheuseofLIFAcentering device
(accessory)ishighlyrecommended.
• Placethemachineinarmposition,
enteringductasdirectlyaspossible.
• Choosea right sized brush(depending
onthesizeoftheductandtypeofdirt).
Makesurethatthebrushisn’ttoosmall
orbigfortheductthatisgoingtobe

GREASE DUCTS: LIFA Combi Cleaner brushing machines may be used for grease duct
cleaning. Please ask us more about our grease removal concept!
cleaned.Nylon grease / Tynex brushes
are meant mainly for grease exhaust
duct cleaning.
• Ifthepurposeistospraycoatingor
disinfectantintotheductatsametime,
placeacompressedairorlow-pressure
airsprayerintothemachinedepending
onthepurposeofuse.Choosea
correctnozzle(checktheaccessorylist).
• Makesurethattheworkingareais
clearedandtherearenoextrapeople.
• Ensurethatalltheemployees
performingtheworkhaveadequate
protective equipment.
• Makesurethatthereisenoughlow
pressureintheductworkandthatLIFA
HepaCleanorLIFAAirCleannegative
pressureunit(NPU)isinstalledcorrectly.
Thebrushedoffdebrisisremovedby
suckingittothenegativepressureunit.
• Connectthecompressedairinto
themachine.Beforeconnecting
thecompressedair,checkthatthe
compressedairtabisoffandairvalves
areinthecentreposition.
• Placethebrushinside the ventilation
ductthatisgoingtobecleaned.
• Whentheoperator,whoisfeedingthe
shaftintotheductgivesapermission
tostartrotation,theotherworkerat
brushingmachineturnstheoperation
valve.Thisisdonebyopeningthe
compressedairtabrstandthenthe
compressedairvalvecanbeturned
intotheotherside,dependingon
therotatingdirection.Thevalveofthe
compressedairtabadjuststherotating
speed.Inthefullyopenpositionthe
rotatingspeedofthebrushisthe
fastestpossible.
• Whentheshaftisbeingfedtotheduct
sharp angles and screws etc. that can
damage the shaft must be beware of.
• Adjusttherotatingspeedofthe
brush.Notethatwhencleaning“soft”
internallyinsulatedductstherotating
speedshouldbemuchlowerthanin
normalducts.Toohighrotationspeed
maydamagetheventilationduct.
• Thebrushcanberotatedtoclockwise
andcounterclockwise.Useboth
rotatingdirectionstoachievethebest
cleaningresult.Inrectangularducts,it
mayberequiredtocleanonesiderst
(withrotatingthebrushinonedirection
only)andafterthatanotherside.
• Feedtheshaftevenlyintotheduct
withoutexcessiveforce.Theuseof
excessiveforcemayharmtheduct,
machineorbrushandinuenceonthe
cleaningresult.Alwaysinserttheshaft
gentlyandsmoothlyintotheductwork,
topreventthebrushfrom‘jumping’and
leavinguncleanspotsintotheduct.
• Itisalsoadvisedtousespecially
designedcenteringdeviceand/orshaft
holderbyLIFAinbigductsand/orwhen
fullrotationspeedisbeingused.

Service and Maintanance
Beforeanymaintenancecompressorneedstobedisconnectedandallpressurefrom
machinereleased.
Thefollowingmaintenanceandupkeepworkmustbedoneinregularbasisdependingon
thepurposeofwhichthemachineisbeingused.Thisenablesatrouble-freeuse.
General Cleanliness: Keepthemachineasfreefromdirtanddustaspossible.Dirtand
greasemaycausedefectsinthecompressedairvalves.Themachinecanbewashedwith
milddetergentandwater.
Maintenance
Lubricating Combi Cleaner 15 motor
Remember to lubricate the pneumatic
motor at the end of each working day by
spraying few seconds of light motor oil*
to the air inlet connector (not to the water
separator) when the operation valve and
air inlet valve are open (Image 1). Tilt the
device slightly so that the oil goes deeper
into the tube.
Connect compressed air to the connector
and run motor few seconds to one direc-
tion only (Image 2).
Repeat the oil spraying and connect
compressed air to the air connector and
run the motor few minutes to the same
direction as rst time until the oil reaches
the motor (motor starts to run faster, and
some oil mist can be seen coming out from
the motors air outlet).
Now the motor is lubricated and ready for
next use.
