NOTE: Align r ibs oninside o fdepth l ocater with grooves inclutch h ousing before snapping into
place.
CHANGING BiT
TIP
1. Pull forward on adjustment collar and remove it from clutch housing (see Figure 3).
2. Use pliers to remove worn bit and install new bit tip.
DEPTH ADJUSTMENT:
Follow the graphic on the collar to increase or decrease the fastening depth. To seat the screw
deeper in the workpiece, turn the adjustment collar to the right. To seat the screw higher in the
workpiece, turn the adjustment collar to the left.
Nutsetting Units
(DW260, DW263, DW266, DW266.220)
iNSTALLING AND CHANGING NUTSETTERS AND LOCATORS
Depth Sensitive Units for Drill Point Screws
1. To change or install a new nutsetter:
a) Pull forward on adjustment collar and remove from clutch housing.
b) Pull nutsetters straight out with pliers
c) Select nutsetter size desired.
d) Two Iocators are supplied, a 9/16" ID for 3/8" nutsetters and 1/2" I D for 5/16" nutsetters.
Match locater to desired size nutsetter or bit holder.
2. Place nutsetter into clutch housing and push end of nutsetter until ball lock snaps into groove
of nutsetter shank.
3. Reassemble adjustment collar by snapping over springs (see Figure 4).
NOTE: Align ribs on inside of depth locater with grooves in clutch housing.
DEPTH ADJUSTMENT
1. For washer head screws: rotate adjustment collar until end of nutsetter is flush with end of
locater.
2. For large washer head and sealer screws: adjust as above until nutsetter is recessed
approximately 1/16" into the locater.
3. Test drive a fastener in scrap material to determine if seating is correct.
4. Adjust following the graphic printed on the tool.

UNITS (DW267, DW268, DW268-220, DW268G, DW269)
External adjustment of all Versa Clutch
TM
units for a wide range of fastener sizes is fast and easy
as follows (see Figure 5):
1. Pull forward, then rotate collar in increase direction (stamped on adjustment collar) to
increase the amount of clutch engagement and torque output.
2. Maximum rotation of the collar in the increase direction results in full clutch engagement and
maximum torque output and fastener capacity. Collar and adjustable stop will not screw off
clutch housing.
3. Test drive a fastener into a scrap piece to check proper fastener seating. It is normal after a
period of use to require a slightly different collar setting due to wear on the clutch faces.
NOTE: With Versa Clutch
TM,
the operator has the ability to "override" clutch ratchet if a fastener
hits a wood knot, variable hardness in steel work pieces or incorrect pilot holes. Increased operator
pressure will usually cause the clutches to pick-up and continue to seat the fastener. Further, a
quick twist of the collar will change the clutch setting to overcome most driving difficulties and will
provide for immediate change in torque output giving the operator the option to drive a wide range
of fastener sizes.
Positive Clutch Units (DW28t_ DW282_ DW284)
1. Install proper bit and set screwdriver for correct rotation.
2. Place fastener on bit and contact work.
3. Apply steady pressure on screwdriver to keep clutches engaged and bit in contact with fas-
tener.
4. Upon fastener seating, clutches will ratchet. Disengage bit from fastener.
Maintenance
CLEANING
With the motor running, blow dirt and dust out of all air vents with dry air at least once a week.
Wear safety glasses when performing this operation. Exterior plastic parts may be cleaned with
a damp cloth and mild detergent. Although these parts are highly solvent resistant, NEVER use
solvents. Drywall Screwdrivers: Depth locater and adjustment collar should be removed and
drywall dust blown out of the clutch housing area at least once a week.
CHANGING CLUTCHES
1. Remove clutch housing by unscrewing (left hand thread).
2. Clamp tool or clutch housing in a resilient clamp.USE CARE, the clutch housing can be
easily damaged.
3. Remove round clutch retaining rings with a very small screwdriver (see Figure 6).
4. install new clutches and new retaining rings. (DW274 series only) Be careful to assemble
the intermediate clutch large end first toward the unit and then the spring. The spring should
run against the output clutch.
NOTE: if the output spindle slides toward inside of gear case, remove gear case and push out-
put spindle forward to expose retaining ring groove. Reassemble dead spindle spring allowing
no more than 1/4" projecting from end of spindle.
5.Relubricate clutches (see Parts Bulletin for DEWALT lubricants identification).
LUBRICATION
All ball and needle bearings are factory lubricated for the life of the bearing.
CLUTCH LUBRiCATiON
1. Remove clutch housing by unscrewing (left hand thread).
2. Lightly brush clutch faces.

_AVERTISSEMENT! Vous devez life et comprendre routes les instructions. Le non-
respect, m@me partiel, des instructions ci-apr@s entrafne un risque de choc 61ectrique, d'in-
cendie et/eu de blessures graves.
CONSERVEZ CES INSTRUCTIONS.
AIRE DE TRAVAIL
_ Veillez ace que I'aire de travail soit propre et bien #c/air#e. Le d6sordre et /e manque de
lumi@re favorisent les accidents.
_ N'utilisez pas d'outils _lectriques clans une atmosph@re explosive, par exemple en
presence de liquides, de gaz ou de poussi#res inflammables. Les outils 61ectriques
creent des 6tincelles qui pourraient enflammer les poussi@res ou les vapeurs.
A Tenez a distance les curieux, les enfants et les visiteurs pendant que vous travaillez
avec un outil #lectrique. IIs pourraient veus distraire et veus faire faire une fausse manoeu-
vre.
S¢:CURITI_ ELECTRIQUE
Les outils mis _ la terre doivent @tre branches dan une prise de courant correctement
install#e et raise _ la terre conform#ment _ tousles codes et reg/ements pertinents.
Ne modifiez jamais la fiche de quelque fagon que ce soit, par exemple en enlevant la broche
de mise 9 la terre. N'utilisez pas d'adaptateur de fiche. Si vous n'@tes pas certain que la prise
de courant est correctement mise 9 la terre, adressez-vous 9 un 61ectricien qualifi6. En cas
de defaillance ou de d6fectuosit6 61ectrique de Ibutil, une mise 9 la terre offre un trajet de
faible resistance 91'61ectricit6 qui autrement risquerait de traverser I'utilisateur. Valable seule-
ment pour les outils de classe I (mis 9 la terre). Les mod@les DW274W et DW286G sent mis
9 la terre.
ALes outils _ double isolation sent _quip#s d'une fiche polaris#e (une des lames est
plus large que I'autre), qui ne peut se brancher que d'une seule facon clans une prise
polarisee Ne modifiez pas la fiche de I'outiL La double isolation [] #limine le besoin
d'un cordon d'alimentation # trois ills avec raise # la terre ainsi que d'une prise de
courant raise a la terre. Valable seulement pour les outils de classe fl (9 double isolation).
Les meddles DW251, DW252, DW255, DW257, DW260, DW262, DW263, DW265, DW266,
DW266-220, DW267, DW268, DW268-220, DW269, DW272, DW274, DW274-220, DW276,
DW276-220, DW281, DW282 et DW284 comportent une double isolation.
Evitez tout contact corporel avec des surfaces raises _ la terre (tuyauterie, radiateurs,
cuisini#res, r#frig#rateurs, etc.). Le risque de choc #lectrique est plus grand si vetre corps
est en contact avec la terre.
N'exposez pas les outils #lectriques # la pluie ou _ I'eau. La presence d'eau dans un eutil
#lectrique augmente le risque de choc #lectrique.
Ne maltraitez pas le cordon. Ne transportez pas I'outil par son cordon et ne debranchez
pas la fiche en tirant sur le cordon. N'exposez pas le cordon 9 la chaleur, 9 des huiles, 9 des
ar@tes vives ou 9 des pi@ces en mouvement. Remplacez immediatement un cordon endom-
mage. Un cordon endommage augmente le risque de choc electrique.
_ Lorsque vous utilisez un outil #lectrique _ I'exterieur, employez un prolongateur pour
I'exterieur marqu# ,,W-A_, ou ,,W,,. Ces cordons sent faits pour @tre uhTises 9 I'ext#rieur et
r#duisent le risque de choc electrique. S'assurer que le cordon de rallonge est en ben #tat.
Lersqu'on se sert d'un cordon de rallonge, s'assurer qu'il est de calibre appropri# pour la ten-
sion n#cessaire au fonctionnement de I'outiL L'utilisation d'un cordon de calibre inferieur
eccasionne une baisse de tension entrafnant une perte de puissance et la surchauffe. Le
tableau suivant indique le calibre appropri# selon la Iongueur du cordon et les mentions de
la plaque signal#tique de I'outiL En cas de doute, utiliser un cordon de calibre sup#rieur. Le
