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 power drive for any broken, missing,
misaligned, or binding parts as well as any condi-
tions, which may affect the safe and normal opera-
tion 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 indi-
cator light goes ON, the tool is ready to use. If bro-
ken, 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 haz-
ardous when used on a hole saw and lead to seri-
ous 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.
