Machine Inspection
WARNING!
To prevent serious injury, inspect your Core Drilling
Machine. The following inspection procedures
should be performed on a daily basis:
1. Make sure Core Drilling Machine is unplugged and the
drill mast switch is set to the OFF position (Figure 1).
2. Inspect the vacuum seal for wear or damage. Replace
if necessary.
3. Inspect the power cord and plug for damage. If the
plug has been modified, is missing the grounding
prong or if the cord is damaged, do not use the
Threading Machine until the cord has been replaced.
4. Inspect the Core Drilling Machine for any broken,
missing, misaligned or binding parts as well as any
other conditions which may affect the safe and normal
operation of the machine. If any of these conditions
are present, do not use the machine until any problem
has been repaired.
5. Lubricate the Core Drilling Machine if necessary ac-
cording to the Maintenance Instructions.
6. Use drill bits and accessories that are designed for
your Core Drilling Machine and meet the needs of your
application. The correct tools and accessories allow
you to do the job successfully and safely. Accessories
designed for use with other equipment may be haz-
ardous when used with this Core Drilling Machine.
7. Clean any oil, grease or dirt from all handles and
controls. This reduces the risk of injury due to a tool or
control slipping from your grip.
Inspect the cutting edges of your drill bits. If neces-
sary, have them replaced prior to using the Core
Drilling Machine. Bit is considered worn when the
crown shows excessive wear and has become flush
with tube. Dull or damaged cutting tools can lead to
binding and tool breakage.
Machine and Work Area Set-Up
WARNING!
To prevent serious injury, proper set-up of the
machine and work area is required. The following
procedures should be following to set-up the ma-
chine.
1. Check that the work area has the following:
• Adequate lighting.
• No Flammable liquids, vapors or dust that may ig-
nite.
• Grounded electrical outlet.
• Clear path to the electrical outlet that does not
contain any sources of heat or oil, sharp edges or
moving parts that may damage electrical cord.
2. Clean up the work area prior to setting up any
equipment. Move tools and debris to prevent slips
and falls.
3. Make sure drill motor ON/OFF switch is in the OFF
position.
4. When plugging the Core Drilling Machine into the
electrical outlet make sure to position the power cord
along the clear path selected earlier. Use an exten-
sion cord in good condition.
To avoid electrical shock and electrical
fires, never use an extension cord that is damaged or
does not meet the following requirements:
• The cord has a three-prong plug similar to shown
in Electrical Safety section.
• The cord is rated as “W” or “W-A” if being used
outdoors.
• The cord has sufficient wire thickness (12 AWG
below 50
′
). If the wire thickness is too small, the
cord may overheat, melting the cord’s insulation or
causing nearby objects to ignite.
To reduce risk of electrical shock, keep all
electrical connections dry and off the ground. Do not
touch plug with wet hands.
