OPERATION
GENERAL OPERATION
CHECK THE POWER SOURCE
The tool comes with a set of accessories which may be 1. Using a calibrated flowmeter and pressure gauge,
customized by each purchaser, so as to facilitate per-
formance of all work occurring within the scope of his
specific application. Tools included are for mounting and
dismounting.
check that the hydraulic power source develops a
flow of 7–9 gpm/26–34 lpm at 950–2000 psi/66–138
bar.
2. Make sure the hydraulic power source is equipped
with a relief valve set to open at 2100–2250 psi/145–
155 bar.

3. Check that the hydraulic circuit matches the tool for
open-center (OC) operation.
DRILL BIT INSTALLATION
CHECK THE TOOL
1. Make certain all tool accessories are correctly in-
stalled. Failure to install tool accessories properly
can result in damage to the tool or personal injury.
WARNING
2. Check the equipment for signs of oil leaks. If leaks
are observed, do not use the tool; have the equip-
ment serviced before use.
Before you start changing the drill bit, make sure that
the tool is disconnected from the power source in
order to avoid unintentional operation of the tool and
injury.
3. Check fasteners for tightness.
4. Check the tool and hydraulic system for proper op-
eration and performance.
Use a single-head wrench SW 24 (small drill bit) or SW
41 (large drill bits) and a single-head wrench SW 32 to
manually unscrew the drill bit to be removed and to
screw on the new one. There is no need to use any ad-
ditional tools.
5. If the equipment does not appear to operate prop-
erly, have it serviced before use.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
DIMENSION OF THE DRILL BIT
Drill head thread: male 1 – 1/4 in. UNC and female R
1/2 in.
2. Connect the hoses from the hydraulic power source
to the tool fittings or quick disconnects. It is good
practice to connect the return hose first and discon-
nect it last to eliminate or reduce trapped pressure
for easier quick-connect fitting attachment.

If uncoupled hoses are left in the sun, pressure in-
crease within the hoses can make them difficult to
connect. When ever possible, connect the free ends
of hoses together.
3. Observe the flow indicators stamped on the hose
couplers to ensure that the flow is in the proper di-
rection. The female coupler on the drill is the inlet
coupler.
4. Cycle the control valve momentarily. If the drill does
not operate, the hoses might be reversed. Verify
correct connection of the hoses before continuing.

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.
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
CAUTION
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.
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.
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.
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.
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.
ATTACHING THE CORE DRILL TO THE
ANCHOR STAND
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.
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.
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.
USING THE ANCHOR STAND WITH A
VACUUM PUMP
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.
1. Connect the vacuum pump to the fitting 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.
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.
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.
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.
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.

TOOL PROTECTION & CARE
NOTICE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
•
•
Make sure all couplers are wiped clean before con-
nection.
•
•
•
•
Always keep critical tool markings, such as warning
stickers and tags legible.
The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydrau-
lic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hy-
draulic system.
Tool repair should be performed by experienced and
trained personnel only.
Make certain that the recommended relief valves
are installed in the pressure side of the system.
Do not use the tool for applications for which it was
not intended.
•
•
Always store the tool in a clean dry space, safe from
damage or pilferage.
Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse cir-
cuit flow. This can cause damage to internal seals.
•
•
Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a mini-
mum working pressure rating of 2500 psi/172 bar.
Do not exceed the rated flow. See Specifications in
this manual for correct flow rate. Rapid failure of the
internal seals may result.

TROUBLESHOOTING
When diagnosing faults in operation of the grinder, always check that the hydraulic power source is supplying the
correct hydraulic flow and pressure to the grinder as listed in the table. Use a flowmeter known to be accurate.
Check the flow with the hydraulic oil temperature at least 80 °F/27 °C.
Problem
Tool will not start
Cause
Solution
Power not being supplied.
Make sure the hoses are connected
and the couplers are tight.
Turn the hydraulic system control

aged. Replace seals.
MAINTENANCE
Good maintenance practice keeps the core drill on the
job and increases its service life.
The most important maintenance practice is to keep
the hydraulic fluid clean at all times. Contaminated fluid
causes rapid wear and/or failure of internal parts.
Follow the recommendations contained in the HYDRAU-
LIC SYSTEM REQUIREMENTS section of this manual
to ensure peak performance from the tool.
Do not disassemble the tool until you know whether the
problem is in the hydraulic power supply, the gearbox
module, or the power and control (rear) module. Then
only disassemble the tool as necessary to repair as re-
quired. KEEP CONTAMINANTS SUCH AS DIRT AND
GRIT AWAY FROM INTERNAL PARTS AT ALL TIMES.
Always determine and correct the cause of the problem
prior to reassembly. Further wear and tool failure can
result if the original cause is not corrected.
