DON’T OVERREACH. Keep proper footing and balance at all
times.

MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean
for better and safer performance. Follow instructions for
lubricating and changing accessories. Inspect tool cords
periodically and if damaged, have repaired by authorized service
facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and
grease.

DISCONNECT OR LOCK OFF TOOLS when not in use, before
servicing, and when changing accessories, such as blades, bits,
cutters.

REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of
checking to see that keys and adjusting wrenches are removed
from tool before turning it on.

AVOID UNINTENTIONAL STARTING. Don’t carry tool with
finger on  switch. Be sure switch is off when plugging in.

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 following 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.

OUTDOOR USE EXTENSION CORDS. When tool is used
outdoors, use only extension cords intended for use outdoors
and so marked.

STAY ALERT. Watch what you are doing. Use common sense.
Do not operate tool when you are tired.

CHECK DAMAGED PARTS. Before further use of the tool, a
guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any other conditions that
may affect its operation. A guard or other part that is damaged
should be properly repaired or replaced by an authorized service
center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service
center. Do not use tool if switch does not turn it on and off.

SAVE THESE INSTRUCTIONS

Motor

Your D

E

WALT tool is powered by a D

E

WALT built motor. Be sure your

power supply agrees with the nameplate marking.

Volts 50/60 Hz or “AC only” means your tool must be operated on
alternating current and never with direct current. 

Voltage decrease of more than 10% will cause loss of power and
overheating. D

E

WALT tools are factory tested; if this tool does not

operate, check power supply.

Motor Brushes

This D

E

WALT tool uses an advanced brush system which automatically

stops the tool when the brushes wear out. This prevents serious
damage to the motor.

Switch

Pressing the BOTTOM part of the switch runs the tool in forward (right
hand thread) direction. Pressing the TOP of the switch reverses motor
direction. This allows "rocking" fasteners to break them loose.
