6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips,
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 the charger before attempting to clean.
7. Do not freeze or immerse the charger in water or any other liquid.
WARNING: Shock hazard. Don’t allow any liquid to get inside the charger. Electric shock may
result.
WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to
enter the battery pack. 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.
Storage Recommendations
1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat or
cold.
2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place out
of the charger for optimal results.
NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need
to be recharged before use.
SAVE THESE INSTRUCTIONS FOR FUTURE USE
COMPONENTS (FIG. 1)
WARNING: Lock the trigger in the off position, disconnect battery pack from tool and remove nail
strips 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.
INTENDED USE
The DCN690 cordless framing nailer has been designed for driving nails into wooden workpieces.
DO NOT use under wet conditions or in presence of flammable liquids or gases.
This cordless framing nailer is a professional power tool. DO NOT let children come into contact with
the tool. Supervision is required when inexperienced operators use this tool.
OPERATION
WARNING: Read the section titled Nailer Safety Warnings 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. Remove battery pack from tool.
3. Lock the pusher in the back position and remove all nail strips from the magazine.
4. 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.
5. 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 nails, leaving work area, moving tool to another location
or handing the tool to another person.
CHARGE INDICATORS
This charger is designed to detect certain problems that can arise. Problems are indicated by the red
light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is working properly. If the new pack
charges correctly, then the original pack is defective and should be returned to a service center or
other collection site for recycling. If the new battery pack elicits the same trouble indication as the
original, have the charger and the battery pack tested at an authorized service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it
automatically starts a 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/cold delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack Charged.
WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected to
perform as much work.
FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will
indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE: This could also mean a problem with a charger.
PROBLEM POWER LINE
Some chargers have a Problem Powerline 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.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the air
temperature is between 65°F and 75°F (18° – 24°C). DO NOT charge the battery pack in an
air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will
prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the 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. A cold battery pack will charge at about half the rate of a warm battery pack. The battery pack
will charge at that slower rate throughout the entire charging cycle and will not return to maximum
charge rate even if the battery pack warms.
4. If the battery pack does not charge properly:
a. Check operation of 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 the charger and battery pack to a location where the surrounding air temperature is
approximately 65°F – 75°F (18° – 24°C);
d. If charging problems persist, take the tool, battery pack and charger to your local service
center.
5. 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 effect on the battery pack.
