Important Safety Instructions for All 
Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains 
important safety and operating instruc tions for the SC121 
battery chargers.
• Before using charger, read all instructions and
cautionary markings on charger, battery pack, and
product using battery pack.
 WARNING: Shock hazard. Do not allow any 
liquid to get inside charger. Electric shock may 
result.
 CAUTION: Burn hazard. To reduce the risk 
of injury, charge only STANLEY rechargeable 
batteries. Other types of batteries may burst 
causing personal injury and damage.
   CAUTION: Children should be supervised to 
ensure that they do not play with the appliance.
 NOTICE: Under certain conditions, with the 
charger plugged in to 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 
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.
• DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual. The 
charger and battery pack are specifically designed to
work together.
• These chargers are not intended for any uses other
than charging STANLEY rechargeable batteries. Any 
other uses may result in risk of fire, electric shock or
electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting
charger. This will reduce risk of damage to electric plug
and cord.
• Make sure that cord is located so that it will not be
stepped on, tripped over, or otherwise subjected to
damage or stress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result
in risk of fire, electric shock, or electrocution.
• Do not place any object on top of charger or place
the charger on a soft surface that might block the
ventilation slots and result in excessive internal
heat. Place the charger in a position away from any heat
source. The charger is ventilated through slots in the top
and the bottom of the housing.
• Do not operate charger with damaged cord or plug
— have them replaced immediately.
• Do not operate charger if it has received a sharp
blow, been dropped, or otherwise damaged in any
way. Take it to an authorised service centre.
• Do not disassemble charger; take it to an authorised
service centre when service or repair is required. 
Incorrect reassembly may result in a risk of electric
shock, electrocution or fire.
• In case of damaged power supply cord the supply cord
must be replaced immediately by the manufacturer, its
service agent or similar qualified person to prevent any
hazard.
• 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
household electrical power. Do not attempt to use
it on any other voltage. This does not apply to the
vehicular charger.
