THE SWITCH
The machine has a lockable trigger switch. Squeeze the trigger to start
the machine. To lock the switch on, press the lock button while holding
the trigger switch on. To release, squeeze the trigger and release.
THE SUCTION CENTERING GUIDE
The optional suction centering guide is a very useful multi-purpose
device which can be used as a drilling guide, a slurry collector ring, and
a dust collector ring. There is an adjustable splash cover to help control
splattering of slurry.The guide firmly attaches to the workpiece with a
suction cup.
To use, align the guide with the location of the intended hole then flip
down the lever of the suction cup to secure in position. The shank of the
core bit will rest against the two guide rollers to keep it from wandering
when the cut begins. Adjust the splash cover to minimize splatter. One
may either attach a vacuum cleaner or simply route the drain hose to
catch the slurry as needed.
DIAMOND CORE DRILLING
NOTE: When drilling with a new bit for the first time, use less than normal feed pressure for a time
until it breaks-in.
1.
Press the "Reset" button on the PRCD interrupter device to energize the circuit to the machine. Then
squeeze the trigger switch to turn the machine on.
2.
Very gently begin the cut. Use the optional suction centering guide to guide the bit and keep it from
wandering. Or, if holding free hand, start the cut by approaching at an angle of about 30 degrees to the
cutting surface. Once about a third of the arc is cut, straighten the bit to the correct perpendicular angle
while keeping enough feed pressure on the bit to prevent it from wandering.
Once the cut is finished, if the core does not drop out of the bit on its own, remove the bit and push out
the core with an appropriate tool.
NOTE: When using larger bits, it is sometimes helpful to use a slight rotating motion to help the cutting
action and allow debris to escape the kerf.
FOR WET DRILLING
1.
Make adjustments to the water feed as needed. The water leaving the cut should be a solid colored
slurry with about the consistency of milk. If the exiting water is clear, then you may reduce the water flow.
If the exiting water is thick and muddy, then increase the water. It's very important that the water
