Important Charging Notes - DeWalt DC545-XE Instruction Manual

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.

Electronic Force Control
The tool is designed to dispense a wide range of adhesive and caulk, and to detect
when material is not dispensing or dispensing slowly. In certain cases, the tool may
not dispense material properly due to solidified adhesive, puncture holes, frozen
materials and the like. Always follow the manufacturer's recommendations regarding
solidified adhesive, puncture holes, frozen materials, etc. to reduce the risk of
damaging the tube or casing.
Remove the battery pack and replace material tube/casing following the manufacturer's
instructions and the instructions under To Insert Material. Take the tool to a D
service center if the tool continues to shut down.
Electronic Auto-reverse
This tool has an auto-reverse feature that reverses the plunger in certain situations
depending on material used and speed of tool.
