Accessories - DeWalt D26450 Guide D'utilisation

NOTE: Do not use sanding screen (e.g., screen used for sanding drywall) directly on the hook
and loop pad. The screen will not hold and will damage the hooks on the pad. The hooks on the
pad will wear very rapidly if left in contact with the work surface while the tool is operating.
Switch (Fig. 3)
To turn the unit on, depress the side of the dust-protected switch (A) that corresponds to the
symbol "I". To turn the tool off, depress the side of the switch that corresponds to the symbol "O".
Speed Control Dial (D26453)
The speed control dial (B), shown in Figure 1, allows you to increase or decrease speed from
7,000–12,000 Orbits Per Minute. The optimal speed setting for each application is very much
dependent on personal preference. Generally, you will want to use a higher setting on harder
materials and a lower setting on softer materials. Material removal rate increases as speed
increases.
Dust Extraction (Fig. 4)
CAUTION: Turn off and unplug the tool before making any adjustments or removing
or installing attachments or accessories. Be sure the switch is in the OFF position.
Your sander has two dust collection methods: a twist-on dust collection bag (D) and a built-in
vac-adapter (E) which can be hooked directly to a shop vaccum system.
TO EMPTY DUST BAG
1. While holding the sander, grasp the dust collection bag (D) at the end nearest the sander
and twist off of the vac-adapter (E).
2. Gently shake or tap the dust collection bag to empty.
3. Twist dust collection bag back onto the vac-adapter.
You may notice that all the dust will not come free from the bag. This will not affect sanding per-
formance but will reduce the sander's dust collection efficiency. To restore your sander's dust
collection efficiency, depress the spring inside the dust bag when you are emptying it and tap it
on the side of the trash can or dust receptacle.
CAUTION: Never operate these tools unless the dust collector is in place. Sanding dust
exhaust may create a breathing hazard.
OPERATION (Fig. 5)
To operate your sander, grasp it as shown in Figures 5A or 5B and turn it on. Move the unit in
long, sweeping strokes along the surface being sanded, letting the sander do the work.
Pushing down on the tool while sanding actually slows the removal rate and produces an
inferior quality surface. Be sure to check your work often, this sander is capable of removing
material rapidly, especially with coarse paper.
The random orbital action of your sander allows you to sand with the grain or at any angle across
it for most sanding jobs. To produce the best finish possible, start with coarse grit sandpaper and
change gradually to finer and finer paper. Vacuum and wipe surface with a tack cloth between
grit steps.Your sander is designed to sand into small or confined areas. Its small size and light
weight make it ideal for overhead work.
The rate at which the dust collection bag fills up will vary with the type of material being sanded
and the coarseness of the sandpaper. For best results, empty the bag frequently. When sand-
ing painted surfaces, (see the following for additional precautions when sanding paint) you may
find that the sandpaper loads up and clogs with paint. A heat gun will work much better to
remove paint before sanding. FOLLOW ALL SAFETY INSTRUCTIONS IN HEAT GUN
INSTRUCTION MANUAL.
NOTE (D26450 only): When using PSA sanding discs, remove the disc soon after operation.
PSA paper, if the disc is left on during tool storage, sometimes becomes difficult to remove. To
aid in the removal of old PSA paper, sand for a few minutes to soften the adhesive backing prior
to changing disc.
Precautions To Take When Sanding Paint
1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the
contaminated dust. The greatest danger of lead poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis,
we recommend the following precautions when sanding any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the work area where the paint sanding is
being done until all clean up is completed.
2. A dust mask or respirator should be worn by all persons entering the work area. The filter
should be replaced daily or whenever the wearer has difficulty breathing. See your local
hardware store for the proper N.I.O.S.H. approved dust mask.
3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingest-
ing contaminated paint particles. Workers should wash and clean up BEFORE eating,
drinking or smoking. Articles of food, drink, or smoking should not be left in the work area
where dust would settle on them.
ENVIRONMENTAL SAFETY
1. Paint should be removed in such a manner as to minimize the amount of dust generated.
2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils
thickness.
3. Sanding should be done in a manner to reduce tracking of paint dust outside the work
area.
CLEANING AND DISPOSAL
1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the
duration of the sanding project. Vacuum filter bags should be changed frequently.
2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or
other removal debris. They should be placed in sealed refuse receptacles and disposed
of through regular trash pick-up procedures. During clean up, children and pregnant
women should be kept away from the immediate work area.
3. All toys, washable furniture and utensils used by children should be washed thoroughly
before being used again.
Tool Care
1. Keep your sander as clean as possible by wiping with a clean cloth and blowing air through
it after every 5 hours of use.
2. As part of CFS (Controlled Finishing System®), your sander is equipped with a replace-
able disc (F) which is located between the pad (C) and the sander body (G). It is designed
to increase the dust collection efficiency and control the pad speed while the unit is off the
work surface. The disc is designed to be a consumable part and will occasionally need to be
replaced. Replacement is necessary when the pad speed increases very dramatically when
the unit is lifted from the work surface.
TO REPLACE YOUR CFS DISC (FIG. 6)
CAUTION: Turn off and unplug the tool before making any adjustments or removing
or installing attachments or accessories. Be sure the switch is in the OFF position.
a. Remove the three screws from the bottom of the pad.
b. Remove the pad (C).
c. Remove worn CFS disc (F).
d. To install the new CFS disc, place the spring side of the disc toward the sander.
e. Align the notches (H) on the CFS disc with the seams in the sander body.
f. Replace the pad and the three screws. Be careful not to over-tighten screws.
3. Don't use harsh chemicals or solvents to clean the tool. These chemicals could seriously
damage the plastic components of your sander.
4. Avoid overloading your sander. Overloading will result in a considerable reduction in speed
and finish quality of your work. The unit may also become hot. In this event, run sander at a
no load condition for a minute or two.
5. If you wrap the cord around the tool when you store it, leave a generous loop of cord such
that the strain relief does not bend. This helps prevent premature cord failure.
Brush Replacement (Fig. 8, 9)
CAUTION: Turn off and unplug the tool before making any adjustments or removing or
installing attachments or accessories. Be sure the switch is in the OFF position.

TO REPLACE BRUSHES
1. Remove the three screws from the top cap and lift off top cap, as shown in Figure 8.
2. Pull the brush spring (I) back (be careful not to pull completely off) and slide out the old
brush.
3. Pull the brush wire (J) which is connected to the brush, out of the motor field (K).
4. Plug the new brush wire back into the motor field.
5. Still holding the brush spring back, slide in the new brush with the wire coming out the top
of the brush and release the brush spring.
6. Repeat steps 1–5 for the second brush.
7. Replace the top cap and tighten the three screws. Be careful not to over-tighten screws.
8. Always replace both brushes.
Lubrication
Self lubricating bearings are used in the tool and periodic relubrication is not required. However,
it is recommended that, once a year, you take or send the tool to a service center for a thorough
cleaning and inspection.
