ATTENTION: BE AWARE THESE MACHINES ARE EXTREMELY POWERFUL. THEY HAVE A TREMENDOUS
AMOUNT OF TORQUE, WHICH MIGHT NOT BE SUITABLE FOR ALL POTENTIAL USERS. ESPECIALLY IN
LOW GEAR AND WITH LARGER BITS. DESPITE THE SAFETY CLUTCH, THESE DRILLS CAN STILL
INJURE THE USER. IF IN DOUBT, CONTACT A PROFESSIONAL FOR ADVICE.
Ø
Turn the machine on by flipping the breaker switch to the “on” position.
Ø
Very slowly engage the cutting bit with the material surface by lightly engaging the hand crank down
towards the material.
o
NOTE: During the initial stages of contact the bit may wander.
Ø
After about 1/8” of cutting has been achieved in the work surface, slightly more force can be applied. This
will be the normal amount of force the rest of the hole.
o
NOTE: Do not force the hole. Let the machine do most of the work. Excessive physical effort
should be avoided as it can cause damage to the machine or the user.
o
If the unit jams in a hole, stop the drill immediately 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.
Ø
Make sure to keep the cutting material lubricated.
Ø
Ease up on feed 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 up in the non-drilling position.
Ø
Turn water valve off.
Ø
Unbolt the wedge anchor.
Ø
Disconnect safety chain/strap and move the drill to a new drilling location.
INSTALLING CORING BITS
Ø
WARNING: Core bits can be sharp and should only be handled with gloves so as not to cut the user during
installation or removal.
Ø
Check that the bits are not damaged.
o
Coring bits that are damaged should not be used.
Ø
Make certain the machine is unplugged from power.
Ø
Raise the drill motor to ensure ample room to install the bit.
o
Apply grease to the spindle thread to prevent corrosion and allow easier core bit removal.
Ø
Insert the coring bit and screw it onto the drill spindle.
Ø
Tighten the bit until fully tightened.
o
Use wrenches that fit the spindle and coring bit to fully tighten.
