If the unit jams in a hole, stop the drill immediately by quickly disengaging the
“on” switch to prevent injury. Disconnect the drill from the power supply and
loosen the cutter by turning drill spindle counterclockwise. Never attempt to
free bit by starting motor!
§
After an interruption in drilling, make sure the drill bit is free and turns
before restarting the hole. Be very careful at this point to make certain
the drill does not bind when restarting.
o
CAUTION: CAUTION: It can take a 1-2 seconds for the safety clutch to engage
otherwise excessive wear and heat will develop.
Ø
Make sure to keep the cutting material lubricated when “wet” drilling.
Ø
Ease up on pressure as the cutter starts breaking through the backside of the
material.
o
Be certain all is clear on the output side of this core to prevent injury to
persons or property.
Ø
Finish drilling the hole.
Ø
Turn the motor off and disconnect power once the drill is safely back to the non-
drilling position.

Turn water valve off.
RUNNING THE MACHINE USING THE OPTIONAL DRILLING RIG
Ø
Do all pre-operational and operational safety checks from Chapter 1.
Ø
Consider your security and stability as well as the orientation of the machine in the
work area.
o
Consider the work surface material, condition, strength, density and rigidity.
These factors directly affect the tools efficiency.
Ø
Ensure the drill is secure in the drilling assembly by inspecting the C clamp assembly
and checking the tension on the C clamp bolts.
o
Ensure the machine’s axis are parallel with the drill stand.
Ø
Secure the machine base to the work surface by using a wedge anchor or other
method to ensure the base does not move.
Ø
Use the four leveling bolts on the corners of the base to level the machine.
Ø
After placing the machine in work area, connect a safety chain or strap if necessary.
o
The safety chain should attach to the machine (preferably through the
carrying handle or O bolt) as well as attached to the work area in such a
manner that prevents the machine from detaching or falling from the work
area.
Ø
Ensure the feed handles are securely attached to the feed spindle.
Ø
Ensure the work surface is free of debris, oil, etc.
Ø
Select the gear you will be using.
