If the charger indicates a problem, take the charger 
and battery pack to be tested at an authorised 
service centre. 
Hot/Cold Pack Delay
When the charger detects a battery that is too hot 
or too cold, it automatically starts a hot/cold pack 
delay, suspending charging until the battery has 
reached an appropriate temperature. The charger 
then automatically switches to the pack charging 
mode. This feature ensures maximum battery life.
XR Li-Ion tools are designed with an Electronic 
Protection System that will protect the battery 
against overloading, overheating or deep discharge. 
The tool will automatically turn off if the Electronic 
Protection System engages. If this occurs, place the 
Li-Ion battery on the charger until it is fully charged.
A cold battery pack will charge at about half the rate 
of a warm battery pack. The battery pack will charge 
at that slower rate throughout the entire charging 
cycle and will not return to maximum charge rate 
even if the battery warms.
Important Safety Instructions for All 
Battery Packs
When ordering replacement battery packs, be sure 
to include the catalog number and voltage. 
The battery pack is not fully charged out of the 
carton. Before using the battery pack and charger, 
read the safety instructions below and then follow 
the charging procedures outlined.
READ ALL INSTRUCTIONS

in explosive atmospheres, such as in the 
presence of flammable liquids, gases or 
dust. Inserting or removing the battery pack 
from the charger may ignite the dust or fumes.
  • Never force the battery pack into charger. 
Do not modify the battery pack in any way 
to fit into a non-compatible charger as 
battery pack may rupture causing serious 
personal injury.

   WARNING: Never attempt to open 
the battery pack for any reason. If 
the battery pack case is cracked or 
damaged, do not insert it into the 
charger. Do not crush, drop or damage 
battery pack. Do not use a battery 
pack or charger that has received a 
sharp blow, been dropped, run over 
or damaged in any way (e.g., pierced 
with a nail, hit with a hammer, stepped 
on). Electric shock or electrocution may 
result. Damaged battery packs should 
be returned to the service centre for 
recycling.
   CAUTION: When not in use, place 
tool on its side on a stable surface 
where it will not cause a tripping or 
falling hazard. Some tools with large 
battery packs will stand upright on the 
battery pack but may be easily knocked 
over.
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION  
(Li-Ion)

Toxic fumes and materials are created when 
lithium ion battery packs are burned.
 • Ifbatterycontentscomeintocontactwith
the skin, immediately wash the area with 
mild soap and water. If the battery liquid gets 
into the eye, rinse water over the open eye for  
15 minutes or until irritation ceases. If medical 
attention is needed, the battery electrolyte 
is composed of a mixture of liquid organic 
carbonates and lithium salts.
