Double Insulation; Polarized Plug; Extension Cords - DeWalt DW441 Manual De Instrucciones

Always use NIOSH/OSHA approved respiratory protection appropri-
ate for the dust exposure. Direct particles away from face and body.
CAUTION: Wear appropriate hearing protection during use.
Under some conditions and duration of use, noise from this product
may contribute to hearing loss.

Double Insulation

Double insulated tools are constructed throughout with two separate
layers of electrical insulation or one double thickness of insulation
between you and the tool's electrical system. Tools built with this insu-
lation system are not intended to be grounded. As a result, your tool
is equipped with a two prong plug which permits you to use extension
cords without concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety pre-
cautions when operating this tool. The insulation system is for added
protection against injury resulting from a possible electrical insulation
failure within the tool.
CAUTION: When servicing all tools, USE IDENTICAL REPLACE-
MENT PARTS. Repair or replace damaged cords.

Polarized Plug

This product is supplied with a polarized plug (one blade is wider than
the other). This plug will fit into a polarized outlet (receptacle) only one
way. If the plug does not fit fully into your outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a proper polar-
ized outlet. Do not modify or change this plug in any way.

Extension Cords

Make sure your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry the current
your product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. The table shows
the correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord.

Motor
Be sure your power supply agrees with nameplate marking.120 AC
means your tool may 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 tools are factory tested; if this
tool does not operate, check the power supply.
Attaching Sanding Discs
Your sander is designed to use 6" sanding discs with the 6 hole dust
extraction pattern.
Hook and Loop (DW442 and DW443)
PSA - Pressure Sensitive Adhesive (DW441 and DW444)
To attach paper to the sanding pad:
1. Turn off and unplug tool.
2. Turn the sander over so that the sanding pad is facing upward.
3. (DW441 and DW444 only) Clean dust from vinyl pad face.
4. Hold the pad with one hand to keep it from rotating.
5. With the other hand, align the holes and place the disc directly on
top of the pad (see FIG. 1).
