HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger
detects a battery that is hot, it automatically starts a Hot Pack Delay,
suspending charging until the battery has cooled. After the battery has
cooled, the charger automatically switches to the Pack Charging mode. This
feature ensures maximum battery life. The red light flashes long, then short
while in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used
with some portable power sources such as generators or sources that convert
DC to AC, the charger may temporarily suspend operation,
flashing the red
light with two fast blinks followed by a pause
. This indicates the power
source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light
glowing indefinitely. The charger will keep the battery pack fresh and fully
charged.
NOTE:
A battery pack will slowly lose its charge when kept out of the
charger. If the battery pack has not been kept on maintenance charge, it
may need to be recharged before use. A battery pack may also slowly lose
its charge if left in a charger that is not plugged into an appropriate AC
source.
WEAK BATTERY PACKS:
Chargers can also detect a weak battery. Such
batteries are still usable but should not be expected to perform as much
work. In such cases, about 10 seconds after battery insertion, the charger
will beep rapidly 8 times to indicate a weak battery condition. The charger
will then go on to charge the battery to the highest capacity possible.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is
charged when the air temperature is between 18°- 24°C (65°F and 75°F).
DO NOT charge the battery pack in an air temperature below +4.5°C
(+40°F), or above +40.5°C (+105°F). This is important and will prevent
serious damage to the battery pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a problem.
To facilitate the cooling of the battery pack after use, avoid placing
the charger or battery pack in a warm environment such as in a metal
shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance
b. Check to see if receptacle is connected to a light switch which turns
power off when you turn out the lights.
c. Move charger and battery pack to a location where the surrounding
air temperature is approximately 18° - 24°C (65°F - 75°F).
d. If charging problems persist, take the tool, battery pack and charger
to your local service center.
4. The battery pack should be recharged when it fails to produce sufficient
power on jobs which were easily done previously. DO NOT CONTINUE
to use under these conditions. Follow the charging procedure. You may
also charge a partially used pack whenever you desire with no adverse
affect on the battery pack.
5. Under certain conditions, with the charger plugged into the power
supply, the exposed charging contacts inside the charger can be shorted
by foreign material. Foreign materials of a conductive nature such as,
but not limited to, steel wool, aluminum foil, or any buildup of metallic
particles should be kept away from charger cavities. Always unplug
the charger from the power supply when there is no battery pack in the
cavity. Unplug charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING:
Shock hazard. Don’t allow any liquid to get inside charger.
Electric shock may result. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm environment such
as in a metal shed, or an uninsulated trailer.
CAUTION:
Never attempt to open the battery pack for any reason. If the
plastic housing of the battery pack breaks or cracks, return to a service
center for recycling.
Installing and Removing the Battery Pack
CAUTION:
Engage contact trip lock-off before removing or installing battery.

NOTE:
Make sure your battery pack is fully charged.
To install the battery pack into the tool handle
, align the base of the tool
with the notch inside the tool’s handle and slide the battery pack firmly into
the handle until you hear the lock snap into place.
To remove the battery pack from the tool
, press the release buttons (M)
and firmly pull the battery pack out of the tool handle. Insert it into the
charger as described in the charger manual (Fig. 4).
COMPONENT
WARNING:
Lock off trigger, disconnect battery pack from tool and
remove fasteners from magazine before making adjustments or personal
injury may result.
Refer to Figure 1 at the beginning of this manual for a complete list of
components.
OPERATION
WARNING:
Read the section titled
Important Safety Instructions for Nailers
at the beginning of this manual. Always wear eye and ear protection when
operating this tool. Keep the nailer pointed away from yourself and others.
For safe operation, complete the following procedures and checks before
each use of the nailer.
1. Wear proper eye, hearing and respiratory protection.
2. Lock the pusher in the back position and remove all fasteners from the
magazine.
3. Check for smooth and proper operation of contact trip and pusher
assemblies. Do not use tool if either assembly is not functioning
properly.
NEVER
use a tool that has the contact trip restrained in the up
position.
4.
NEVER
use a tool that has damaged parts.
WARNING:
To reduce the risk of personal injury, disconnect battery pack
from tool before performing maintenance, clearing a jammed fastener,
leaving work area, moving tool to another location or handing the tool to
another person.
Mode Selection
WARNING: ALWAYS
wear proper eye [ANSI Z87.1 (CAN/CSA Z94.3)] and
ANSI S12.6 (S3.19) hearing protection when operating tool.
The D
E
WALT cordless nailers are assembled in accordance with the ANSI
Standard SNT-101-2002.
FIG. 5
Before operating this tool, look at the selector switch to determine the
actuation mode. Read all instructions before selecting actuation mode.
WARNING:
Keep fingers AWAY from trigger when not driving fasteners to
avoid accidental firing.
NEVER
carry tool with finger on trigger. In Bump
mode tool will fire a fastener if safety is bumped while trigger is depressed.
SEQUENTIAL ACTION
Use sequential action for intermittent nailing where very careful and accurate
placement is desired.
To operate the nailer in sequential action mode:
1. Flip the switch located on the body
FIG. 6
of the tool just between the trigger and
magazine to the left, as shown in Figure 6.
2. Fully depress nosepiece against the work
surface (motor will start).
3. Pull trigger (nail will drive into work
surface).
4. Release trigger.
5. Lift nosepiece off work surface.
6. Repeat steps 2 through 4 for next application.
CAUTION:
The contact trip needs to be depressed followed by a trigger
pull for each nail followed by a release of both the contact trip and trigger
after each nail.
BUMP ACTION
Bump action is intended for rapid nailing on flat,
FIG. 7
stationary surfaces.
When using bump action, two methods are
available:
place actuation
and
bump actuation
.
Flip the switch located on the body of the tool just
between the trigger and magazine to the right as
shown in Figure 7.
To operate the tool using the PLACE ACTUATION
method:
CAUTION:
A nail will fire each time the trigger is depressed as long as the
contact trip remains depressed.
1. Depress the contact trip against the work surface.
2. Depress the trigger.
To operate the tool using the BUMP ACTUATION method:
1. Depress the trigger.
2. Push the contact trip against the work surface. As long as the trigger
is depressed, the tool will fire a nail every time the contact trip is
depressed. This allows the user to drive multiple nails in sequence.
CAUTION:
Do not keep trigger depressed when tool is not in use. Keep
the contact trip lock-off engaged in the locked position when the tool is not in
use.
