Precautions To Take When Sanding Paint; Maintenance - DeWalt DWE6421 Instruction Manual

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 sanding 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.

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 NIOSH-approved dust mask.
3. NO EATING, DRINKING or SMOKING should be done in the
work area to prevent ingesting 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.

MAINTENANCE

WARNING: To reduce the risk of injury, turn unit off and
disconnect tool from power source before installing and
removing accessories, before making any adjustments or
removing/installing attachments or accessories. An accidental
start-up can cause injury.
Your D WALT power tool has been designed to operate over a long
e
period of time with a minimum of maintenance. Continuous satisfactory
operation depends upon proper tool care and regular cleaning.
Replacing the Sanding Pad and the Belt
(Fig. 6)
Your sander is equipped with a replaceable belt (K) which is located
between the pad (E) and the sander body (H). It is designed to control
the pad speed while the unit is off the work surface. The belt and
the sanding pad (E) are designed to be consumable parts and will
occasionally need to be replaced. The sanding pad needs replacement
when signs of wear become evident. Replacement of the belt is
necessary when the pad speed increases very dramatically when the
