DRILLING WITH CD12 ANCHOR
STAND
The anchor stand may be used with a vacuum pump for
a vacuum hold down or with a concrete anchor screw to
hold the stand in place while drilling. The standard ar-
rangement of the anchor stand is for use with a vacuum
pump.
CAUTION
Use of a vacuum to hold the anchor stand on other
than horizontal surfaces is not recommended. Loss
of vacuum will allow the stand to slip or fall. The
result may be personal injury or damage to the drill
and stand.
The carriage feed handle may be installed on either end
of the pinion gear spindle. Align the cross screw in the
handle with the slot in the spindle and push the handle
on until the spring detent in the handle snaps into the
groove on the spindle.
ATTACHING THE CORE DRILL TO THE
ANCHOR STAND
1. Back out the drill mount locking screw that is in the
carriage. Slide the dovetail block attached to the
core drill into the carriage.
2. Tighten the drill mount locking screw into the dove-
tail block. The tip of the locking screw engages a
hole in the dovetail block.
USING THE ANCHOR STAND WITH A
VACUUM PUMP
1. Connect the vacuum pump to the tting on the base
of the anchor stand.
2. Screw the leveling screws up to the underside of the
base to allow the base gasket to compress when the
vacuum is created.
3. Make sure that the base gasket is in good condition
to hold the vacuum.
4. Position the anchor stand so that the drill and bit are
aligned where the hole is to be drilled.
5. For a good vacuum seal make sure the surface that
the base gasket will contact is free of debris.
6. Turn on the vacuum pump.
7. To reposition the anchor stand as required to accu-
rately place the drill bit, press the vacuum release
button and move the anchor stand. Release the but-
ton to re-establish the vacuum.
8. Turn the leveling screws down to contact the sur-
face to be drilled. This will provide a solid, stable
footing for the stand.
9. Tighten the jam nuts to lock the leveling screws.
USING THE ANCHOR STAND WITH
AN ANCHOR SCREW
1. Remove the vacuum handle and gasket from the
base. The screw that holds the vacuum handle in
place is located on the underside of the base.
2. Remove the base gasket from the base.
3. Screw the leveling screws up to the underside of the
base. Make sure the area where the anchor stand is
to be placed is clear of debris.
4. Place the anchor stand to position the drill bit.
5. With a marking pen through the slot in the base,
mark on the surface a line along which to place the
screw anchor.
6. Put the anchor stand aside. Drill and set the screw
anchor. Place the anchor stand over the screw an-
chor, put the anchor screw through the slot in the
base and tighten just snug. Make sure the drill bit is
correctly positioned.
7. Turn the leveling screws down to contact the sur-
face to be drilled. Tighten the jam nuts to lock the
leveling screws.
8. Tighten the anchor screw to hold the anchor stand
in position.
9. The “Bulls Eye” level on the drill carriage is used for
indicating level when drilling into a horizontal sur-
face. You can use the leveling screws to make slight
adjustments to level the anchor stand.
10. There is a hex socket head capscrew through the
very bottom of the mast into the base. This capscrew
solidly holds the mast square to the base. If you want
to drill a hole at an angle to the base, this capscrew
must be removed.
11. To adjust the mast to any angle up to 45 degrees,
you must loosen the clamping screw located in the
slidable handle on the back of the mast. Move the
mast to the desired angle and tighten the clamping
screw.
