WHEN USING (THIS APPLIANCE)
• Do not operate power tools in an explosive atmosphere, such as in the presence of ammable
liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes.
• To reduce the risk of electric shocks, the batttery charger has a polarized plug (one blade
is wider than the other) and will require the use of a polarized extension cord. The plug will
only t into a polarized extension cord one way. If the plug does not t fully into the extension
cord, reverse the plug. If the plug still does not t, obtain a correct polarized extension cord.
A polarized extension cord will require the use of a polarized wall outlet. This plug will only t
into the polarized wall outlet one way. If the plug does not t fully into the wall outlet, reverse
the plug. If the plug still does not t, contact a qualied electrician to install the proper wall
outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug
in any way.
• Never allow children to operate the equipment. Never allow adults to operate the equipment
without proper instruction.
