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

 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.
 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. 
 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.
 Unplug  charger  from  outlet  before  attempting  any 
maintenance or cleaning to reduce the risk of electric 
shock.
 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 onto the connector. 
It also will help prevent damage to the charger during a 
power surge.
 Disconnect charger from tool when the battery is fully 
charged.
Risk of electric shock. Do not touch uninsulated portion 
of output connector or uninsulated battery terminal.
 For best results, your battery tool should be charged in 
a location where the temperature is more than 50° but 
less than 100°. To reduce the risk of serious personal 
injury, do not store outside or use in vehicles.

WARNING!
READ  AND UNDERSTAND ALL  INSTRUCTIONS. 
Failure to follow all instructions listed below, may result in 
electric shock, fire and/or serious personal injury. 
 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.
WARNING: 
To  reduce  the  risk  of electric shock  or  damage to 
the  charger  and  battery,  charge  only  the  UT44172  as 
specifically designated on your charger. Other types of 
batteries may burst, causing personal injury or damage. 
A charger that may be  suitable for one type of battery 
pack may create a risk of fire when used with another 
battery pack.
 Do not use charger outdoors or expose to wet or damp 
conditions. Water entering charger will increase the risk 
of electric shock.
 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.
 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.
 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.
 Keep cord and charger from heat to prevent damage 
to housing or internal parts.
 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.
