Electrical Connection

Be sure your power source agrees with the nameplate marking. 120 volts, AC means that
your saw will operate on alternating current. Do not operate with DC power. A voltage
decrease of 10 percent or more will cause a loss of power and overheating. All D
are factory tested. If this tool does not operate, check the power supply.
This miter saw operates on either two 60V battery packs or by using the D
power supply.
Using the Corded Power Supply
WALT corded power supply is designed to Fig. 1
The D
e
provide power for D
e
cordless tools. Insert the corded power supply into the
miter saw battery slot (refer to Installing and
Removing the Corded Power Supply) and plug the
power supply into an AC outlet. The power supply will
act as the power source to the tool. Your D
corded power supply should only be used with
standard household 120 VAC, 60 Hz power or a
120 VAC 60Hz generator.
The corded power supply is suitable for use with both
grounded and double insulated 120V AC tools. When the power supply is utilized with a
grounded tool, the tool inlet will be equipped with a ground prong that allows the ground path
from the tool to connect to the power supply. When the power supply is used with this double
insulated miter saw, no ground connection is made from the tool to the power supply as no
ground connection is required.
Additional Specific Usage Instructions
The corded power supply may become warm to the touch during use. This is a normal
condition and does not indicate a problem.
IMPORTANT. The power supply is not user serviceable. There are no user serviceable parts
inside the power supply.
Servicing at an authorized service center is required to avoid damage to static sensitive
internal components.

Batteries and Chargers

The battery pack is not fully charged out of the carton. Before using the battery pack and
charger, read the safety instructions below and then follow charging procedures outlined.
When ordering replacement battery packs, be sure to include the catalog number and voltage.
Your tool uses a D WALT charger. Be sure to read all safety instructions before using
e
your charger. Consult the chart at the end of this manual for compatibility of chargers and
battery packs.

Important Safety Instructions for All Battery Packs

• Do not charge or use the battery pack in explosive atmospheres, such as
in the presence of flammable liquids, gases or dust. Inserting or removing the
battery pack from the charger may ignite the dust or fumes.
• Never force the battery pack into the charger. Do not modify the battery
pack in any way to fit into a non-compatible charger as battery pack may
rupture causing serious personal injury. Consult the chart at the end of this
manual for compatibility of batteries and chargers.
• Charge the battery packs only in designated D
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the
