Inspect Hole Cutting Tool
WARNING
To prevent serious injury, inspect your Hole
Cutting Tool on a regular basis. The following
inspection procedures should be performed
before each use of the tool:
1. Inspect the power cord and plug for damage. If the
grounding prong is missing or the cord or GFCI is
damaged, do not use the tool until the cord has
been replaced.
2. Make sure the switches turn the tool ON and OFF.
If broken, do not use until they are replaced.
3. Inspect the hole cutting tool for any broken, miss-
ing, misaligned, or binding parts as well as any
conditions, which may affect the safe and normal
operation of the tool. If any of these conditions are
present, do not use the tool until the problem has
been repaired. Do not use dull, bent, or damaged
hole saws or arbors.

4. Test the Ground Fault Circuit Interrupter (GFCI) to
insure it is operating correctly. When test button is
pushed in, the indicator light should go OFF.
Reactivate by pushing the reset button in. If the
indicator light goes ON, the tool is ready to use. If
broken, do not use the tool until it is replaced.
5. Clean any oil, grease, or dirt from the handles.
This reduces the risk of injury due to the tool slip-
ping from your grip.
6. Use only accessories recommended for your tool.
Accessories used for other tools may be hazardous
when used on a hole saw and lead to serious
injury.
7. Inspect the cutting edges of your hole saws. If nec-
essary, replace prior to using in your hole-cutting
tool. Dull or damaged cutting edges can lead to
injury, tool breakage, or excessive heat buildup in
the workpiece and the tool.
