the tool serviced before using.  Many accidents are caused by poorly
maintained tools.

21.

Use only accessories that are recommended by the manufacturer for your
model.  
Accessories that may be suitable for one tool may become hazardous
when used on another tool.

SERVICE

22.

Tool service must be performed only by qualified repair personnel.  Service
or maintenance performed by unqualified personnel could result in a risk of injury.

23.

When servicing a tool, use only identical replacement parts.  Follow
instructions in the 

“Inspection, Maintenance, And Cleaning” section of this

manual.  Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.

GROUNDING

SKU 90234

PAGE 5

WARNING!

Improperly connecting the grounding wire can result in the risk of electric

shock.  Check with a qualfified electrician if you are in doubt as to whether the

outlet is properly grounded.  Do not modify the power cord plug provided with

the tool.  Never remove the grounding prong from the plug.  Do not use the

tool if the power cord or plug is damaged.  If damaged,  have it repaired by

a service facility before use.  If the plug will not fit the outlet, have a proper

outlet installed by a qualified electrician.

GROUNDED TOOLS: TOOLS WITH THREE  PRONG  PLUGS

1.

Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug.  The plug must be connected to a properly grounded outlet.  If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of elec-
tric shock.  (See Figure A, next page.)

2.

The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool.  The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal.  (See Figure A.)
