Charging A Battery; Important Charging Notes - Craftsman CMCHTS820 Manual De Instructiones

English
required. Incorrect reassembly may result in a risk of
electric shock, electrocution or fire.
• Disconnect the charger from the outlet before
attempting any cleaning. This will reduce the risk
of electric shock. Removing the battery pack will not
reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on standard
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.

WARNING:
any liquid to get inside the charger. Electric shock
may result.

WARNING:
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.

CAUTION:
risk of injury, charge only CRAFTSMAN rechargeable
battery packs. Other types of batteries may
overheat and burst resulting in personal injury and
property damage.

CAUTION:
the charger plugged into the power supply, the
charger can be shorted by foreign material. 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 the 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.

Charging a Battery

nOTE: To ensure maximum performance and life of
lithium-ion battery packs, charge the battery pack fully
before first use.
1. Plug the charger into an appropriate outlet before
inserting battery pack.
2. Connect the charger and battery pack, making sure
the battery is fully seated. The (charging) light will
blink continuously indicating that the charging process
has started.
3. The completion of charge will be indicated by the light
remaining ON continuously. The battery pack is fully
charged and may be removed and used at this time or
left in the charger.
nOTE: To remove the battery pack, some chargers require
the battery pack release button to be pressed.

Hot/Cold Pack Delay
A charger will not charge a faulty battery pack. The charger
refusing to light could indicate a problem with the charger.
nOTE: If the charger refuses to light, take the charger and
battery pack to be tested at an authorized service center.
hot/Cold Pack Delay
When the charger detects a battery pack that is too hot
or too cold, it automatically starts a Hot/Cold Pack Delay,
suspending charging until the battery pack has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
maximum battery pack life.
A cold battery pack may charge at a slower rate than a
warm battery pack.

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 – 75 °F (18 ° C– 24 °C). DO NOT charge
when the battery pack is below +40 °F (+4.5 °C), or
above +104 °F (+40 °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. 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 °C – 24 °C);
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 effect on the battery pack.
5. 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.
