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, mis-
aligned, 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 in-
sure it is operating correctly. When test button is
pushed in, the indicator light should go OFF. Re-
activate 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 slipping
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 work-
piece and the tool.

WARNING
When setting up the hole saw, it should be un-
plugged and the switch should be in the OFF posi-
tion. To prevent serious injury the tool must be
properly set up.
1. Determine the size and location of hole to be cut.
Follow coupling manufacturer's recommendations
for hole size to coupling size.
