SAFETY RULES FOR CHARGER

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.

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

  

Do not use charger outdoors or expose to wet or damp 
conditions. 

Water entering charger will increase the risk 

of electric shock.

n

  

Use of an attachment not recommended or sold by the 
battery charger manufacturer may result in a risk of 
fire, electric shock, or injury to persons. 

Following this 

rule will reduce the risk of electric shock, fire, or serious 
personal injury.

 

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  con-

tain  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

NOTE:

 AWG = American Wire Gauge

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.

Risk of electric shock. 

Do not touch uninsulated portion 

of output connector or uninsulated battery terminal.

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.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemi-
cals 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.
