Selection of appropriate materials and instal-
NOTI E
lation, joining and forming methods is the responsibility of
the system designer and/or installer. Selection of im-
proper materials and methods could cause system failure.
Stainless steel and other corrosion resistant materials
can be contaminated during installation, joining and form -
ing. This contamination could cause corrosion and pre-
mature failure. Careful evaluation of materials and methods
for the specific service conditions, including chemical and
temperature, should be completed before any installation
is attempted.

Pre-Operation Inspection

WARNING
Before each use, inspect your Hole Cutting Tool
and correct any problems to reduce the risk of se-
rious injury from electric shock and other causes and
prevent tool damage.
1. Make sure that the Hole Cutting Tool is unplugged and
the ON/OFF switch is in the OFF position.
2. Clean any oil, grease or dirt from the tool, including the
handles and controls. This aids inspection and helps
prevent the tool or control from slipping from your grip.
3. Inspect the Hole Cutting Tool for the following items:
• Inspect the power cord, Ground Fault Circuit Inter -
rupter (GFCI) and plug for damage or modification.
• Proper assembly and completeness.
• Broken, worn, missing, mis-aligned or binding parts.
Make sure that the motor assembly moves smooth -
ly and freely up and down the posts of the base as-
sembly. Confirm that the chain and swivel handle
move freely. On the HC-300, confirm that the plung -
er pin functions properly and retains the motor as-
sembly to the base assembly (Figure 7).

• Presence and readability of the warning labels (see
Figures 4A and 4B).
• Any other condition which may prevent safe and
normal operation.
If any problems are found, do not use the hole cutting
tool until the problems have been repaired.
4. Inspect the arbor, hole saw and drills to be used with
the Hole Cutting Tool for wear, deformation, breakage
or other issues. Do not use dull or damaged cutting
tools. Dull or damaged cutting tools increase the
amount of force required, produce poor quality cuts
and increase the risk of injury.
5. With dry hands, plug the cord in. Test the GFCI in the
electrical cord to insure that it is operating correctly.
When the test button is pushed in, the reset button
should pop out. Reactivate by pushing the reset but-
ton. If the GFCI is not functioning properly, unplug the
cord and do not use the hole cutting tool until the
GFCI has been repaired.
