WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. 
Failure to follow all instructions listed below, may 
result in electric shock, fire and/or serious personal 
injury.
n
Before using battery charger, read all instructions and
cautionary markings in this manual, on battery charger, 
battery, and product using battery to prevent misuse of 
the products and possible injury or damage.
n
CAUTION: To reduce the risk of electric shock or damage 
to the charger and battery, charge only nickel-cadmium 
rechargeable batteries as specifically designated on your 
charger. Other types of batteries may burst, causing 
personal injury or damage.
n
Never use a battery that has been dropped or received a
sharp blow. A damaged battery is subject to explosion. 
Properly dispose of a dropped or damaged battery 
immediately.
n
Do not expose charger to wet or damp conditions. Water
entering charger will increase the risk of electric shock.
n
Do not use any attachment or accessory not
recommended by the battery charger manufacturer. 
Attachments and accessories that may be suitable for 
one tool may become hazardous when used on another 
tool.
n
Do not abuse cord or charger. Never use the cord to carry
the charger. Do not pull the charger cord rather than the 
plug when disconnecting from receptacle. Damage to 
the cord or charger could occur and create an electric 
shock hazard. Replace damaged cords immediately.
n
Make sure cord is located so that it will not be stepped
on, tripped over, come in contact with sharp edges or 
moving parts or otherwise subjected to damage or stress. 
This will reduce the risk of accidental falls, which could 
cause injury, and damage to the cord, which could result 
in electric shock.
n
Keep cord and charger from heat to prevent damage to
housing or internal parts.
n
Do not let gasoline, oils, petroleum-based products, etc.
come in contact with plastic parts. They contain chemicals 
that can damage, weaken, or destroy plastic. 
n
An extension cord should not be used unless absolutely 
necessary. Use of improper extension cord could result 
in a risk of fire and electric shock. If extension cord must 
be used, make sure:
a. That pins on plug of extension cord are the
same number, size and shape as those of
plug on charger.
b. That extension cord is properly wired and in
good electrical condition; and
c. That wire size is large enough for AC ampere
rating of charger as specified below:
Cord Length (Feet)
25'
50'
100'
Cord Size (AWG)
16
16
16
Note: AWG = American Wire Gage
n
Do not operate charger with a damaged cord or plug,
which could cause shorting and electric shock. If 
damaged, have the charger replaced by an authorized 
serviceman.
n
Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take 
it to an authorized serviceman for electrical check to 
determine if the charger is in good working order. 
n
Do not disassemble charger. Take it to an authorized
serviceman when service or repair is required. Incorrect 
reassembly may result in a risk of electric shock or fire.
n
Unplug charger from outlet before attempting any
maintenance or cleaning to reduce the risk of electric 
shock.
n
Disconnect charger from the power supply when not in
use. This will reduce the risk of electric shock or damage 
to the charger if metal items should fall into the opening. 
It also will help prevent damage to the charger during a 
power surge.
n
Save these instructions.Refer to them frequently and use
them to instruct others who may use this tool. If you loan 
someone this tool, loan them these instructions also to 
prevent misuse of the product and possible injury.
IMPORTANT SAFETY INSTRUCTIONS FOR CHARGER
SAVE THESE INSTRUCTIONS
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these 
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure 
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust 
masks that are specially designed to filter out microscopic particles.
