Use the product in accordance with these instructions
and in the manner intended for the product, taking
into account the working conditions and the work
to be performed. Use of the product for operations
different from those intended could result in a hazardous
situation.
Use battery products only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury and fire.
When servicing a battery product, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized
parts or failure to follow Maintenance instructions may
create a risk of shock or injury.
Know your battery product. Read operator’s manual
carefully. Learn its applications and limitations, as well
as the specific potential hazards related to this power
tool. Following this rule will reduce the risk of electric
shock, fire, or serious injury.
Do not place battery products or their batteries near
fire or heat. This will reduce the risk of explosion and
possibly injury.
Do not crush, drop or damage battery pack. Do not
use a battery pack or charger 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.
Batteries can explode in the presence of a source
of ignition, such as a pilot light. To reduce the risk of
serious personal injury, never use any cordless product
in the presence of open flame. An exploded battery can
propel debris and chemicals. If exposed, flush with water
immediately.
Do not use battery tool in a damp or wet location.
Following this rule will reduce the risk of electric shock.
Under extreme usage or temperature conditions,
battery leakage may occur. If liquid comes in contact
with your skin, wash immediately with soap and water.
If liquid gets into your eyes, flush them with clean water
for at least 10 minutes, then seek immediate medical
attention. Following this rule will reduce the risk of serious
personal injury.
