ASSEMBLY

Replacing the Sanding Belt
WARNING: BE SURE SANDER IS TURNED OFF AND DISCONNECTED FROM THE
POWER SUPPLY WHEN CHANGING THE SANDING BELT. BEFORE RECONNECTING
THE TOOL, DEPRESS AND RELEASE THE TRIGGER SWITCH TO ENSURE THAT THE
TOOL IS OFF.
TO REMOVE SANDING BELT (FIG. 2)
1. Rotate the belt release lever (A) up until the top front wheel of the sander retracts releasing
the tension on the abrasive belt.
2. Set the sander on its side so all three wheels are visible.
3. Remove the worn out belt.
TO INSTALL SANDING BELT
1. Slip a new belt around the wheels. Arrows printed on the inside of the belt point in the direc-
tion in which the wheels turn. Orient the belt in the direction of wheel rotation. Be sure the
belt does not go over the tracking flange (B) located on the inside of the top, front wheel as
shown in Figure 3.
2. Rotate the belt release lever (A) down into position to reapply tension to the belt.
NOTE: Some sanding belts are multi-directional and do not have arrows. The direction of rota-
tion is also indicated on the brush cover (C) in Figure 1.
MOTOR
Your D WALT tool is powered by a D
E
with the nameplate marking. Volts 50/60 Hz or "AC only" means your tool must be operated
only with alternating current and never with direct current. Voltage decrease of more than
10% will cause loss of power and overheating. All D
tool does not operate, check the power supply.

OPERATION

Switch Operation
To start the belt sander, depress the trigger switch (D). Allow the belt sander to reach oper-
ating speed before touching the work surface.
To slow or stop the belt sander, release the trigger switch.
For continuous operation, press in the lock button (E) while the trigger switch is depressed
and the belt sander is running (Fig. 2).
To release from continuous operation, squeeze the trigger and the lock will disengage.
WARNING: BE SURE THE LOCK BUTTON IS NOT DEPRESSED BY CYCLING THE
SWITCH SEVERAL TIMES OR BY DEPRESSING AND RELEASING THE SWITCH
SEVERAL TIMES BEFORE PLUGGING IN YOUR BELT SANDER! DAMAGE TO YOUR
TOOL OR PERSONAL INJURY MAY RESULT.
Variable Speed (DW433 ONLY)
The speed control dial, located on the back of the rear handle, moves the speed of the sanding
belt from approximately 850 surface feet per minute on speed #1 (light sanding; fine grit sand-
ing belts) to approximately 1400 surface feet per minute on speed #6 (more aggressive sand-
ing; coarse sanding belts). Low speeds also prevent excessive belt wear and overheating when
removing paint with the belt sander.
Front Handle
There are two positions for the front handle: top position and front position. The unit comes with
the handle installed in the top position (F) as shown in Figure 1.
TO POSITION THE HANDLE
1. Loosen the screw in the center of the handle using a Phillips screwdriver.
2. Attach the handle to the threaded hole in the front (G) or the top (F) of the unit.
3. Tighten the screw.
NOTE: The handle must be properly seated over the mounting surface before tightening the
screw.
Tracking the Belt
Your belt sander is equipped with an automatic tracking system that prevents the belt from
moving into the housing while the sander is operating. The automatic tracking system prevents
damage to the sander housing and the destruction of the sanding belt.
TO PROPERLY TRACK THE SANDING BELT (FIG. 2)
1. Grasp the rear handle (H) of the unit firmly and flip the sander so that the belt is facing the
operator.
2. Depress the trigger (D) to begin rotation of the belt.
3. Turn the tracking knob (I) counterclockwise to move the belt toward the housing. Turn the
knob clockwise to move it away from the housing.
NOTE: The belt should be aligned with the flush edge of the platen (J) while the sander is in oper-
ation (Fig. 4).
4. Release the trigger and make sure the belt has come to a complete stop before setting the
unit down.
Proper Hand Position
Safe belt sanding is a two-handed operation. One hand is used to grip the rear handle of the unit
while the other hand is used to grip the front handle as seen in Figure 4.
Dust Collection System
WARNING: Turn off and unplug sander before making any adjustments or removing or
installing accessories. Before reconnecting the tool, depress and release the trigger switch to
ensure that the tool is off.
TO ATTACH THE DUST COLLECTOR (FIG. 5)
1. Pull the locking dust chute collar (K) up.
2. Insert the rubber dust ejection chute into the collar. Make sure the slots on the collar are
aligned with the nubs (L) on the ejection chute.
3. Push the dust collector from the rear of the bag until the ejection chute snaps into the dust
chute collar and the locks onto the belt cover (M).
4. Push the locking dust chute collar down to secure the dust collector to the unit.
TO EMPTY THE DUST COLLECTOR
1. Pull up on the locking dust chute collar.
2. Remove the dust collector, the rubber ejection chute, and dust collector from the unit
together.
3. Once the dust collector is disconnected from the unit, release the dust seal latch (N) on the
underside of the collector (Fig. 6).
4. Squeeze the dust chute in the spaces indicated (O) to release the collector.
5. Pull the dust bag up to release it from the chute.
6. Slide the dust collector off of the rubber dust ejection chute.
7. Shake the bag and ejection chute over a trash can, tapping the bag lightly against the can
to loosen any compacted dust particles.
8. When the dust collector is empty, reattach it to the dust ejection chute and then to the
sander.
DUST COLLECTION SHUT-OFF VALVE (FIG. 2)
When sanding in tight places, the dust collector may be removed.
CAUTION: With the dust collector removed, the stream of dust will be blown through the
exhaust port toward the operator unless the dust collection valve is closed.
To close the dust collection valve, push the lever (P) forward. This will prevent the flow of
dust from the exhaust port.
To open the dust collection valve, pull the lever (P) backward. This will allow the flow of dust
to exit the exhaust port.

CONSERVEZ CES DIRECTIVES
MISE EN GARDE ! Lire, comprendre et suivre toutes les directives suivantes, y
compris celles fournies avec les accessoires, afin d'éviter tout risque de choc
électrique, d'incendie ou de blessure grave.
RÈGLES DE SÉCURITÉ – GÉNÉRALITÉS
ZONE DE TRAVAIL
• Maintenez votre zone de travail propre et bien éclairée. Les établis encombrés et les
zones sombres invitent les accidents.
• Ne pas faire fonctionner d'outil électrique dans un environnement explosif, en
présence de liquides, gaz ou poussières inflammables. Les outils électriques produisent
des étincelles qui peuvent enflammer poussières ou vapeurs environnantes.
• Se tenir éloigné de toute personne présente (enfants ou visiteurs), lors de l'utilisation
d'outil électrique. Toute distraction peut vous en faire perdre le contrôle.
MESURES DE SÉCURITÉ – ÉLECTRICITÉ
• Les outils mis à la terre doivent être branchés dans une prise aux normes et mise à la
terre conformément aux codes et règles en usage. Ne jamais retirer la broche de masse
ou modifier la prise de quelque façon que ce soit. N'utilisez pas d'adaptateur de mise à
la terre. Renseignez-vous auprès d'un électricien qualifié si vous avez des doutes quant à la
mise à la terre de votre prise. Si l'outil devait subir une défaillance électrique ou une avarie, la
mise à la terre procure au courant un chemin de plus faible résistance afin de réduire les
risques de choc électrique. Valide seulement pour les outils de Classe I (mis à la terre).
• Les outils munis d'une double isolation sont équipés d'une fiche polarisée (l'une des
lames est plus large que l'autre). Ce genre de fiche ne rentre dans une prise polarisée
que dans un seul sens. Et on doit l'inverser si on est incapable de l'enfoncer. Si le prob-
