4-
Warning
Woodworking machines are dangerous and can cause personal injury if not used properly.
Read safety instructions and operating instruction for your machine completely before using products.
Using this system before understanding its safe and proper use could result in serious injury to the operator.
Failure to follow these rules may result in serious personal injury.
For your own safety, read instructions manual before operating the tool. Learn the tools application and limitations as well as
the specific hazards peculiar to it.
Keep all guards and safety devices in proper place while using these products.
Always wear safety glasses.
Keep hands well away from the pneumatic or mechanical clamp and rotating bit when operating machine.
Avoid awkward hand positions, where a sudden slip could cause contact with rotating bit. Never reach under the clamp pad
with either hand to hold down the workpiece.
Kickbacks
Beware of kickbacks; they can cause serious injury. A kickback occurs when the workpiece binds up while being drilled, causing
it to twist, jump, or become airborne.
To Avoid kickbacks:
Always use sharp drill bits.
Keep machine in proper alignment and good working condition.
Never perform any “free hand” drilling. Work must always be held securely against the table and fence.
Always support longer boards when drilling.
To avoid injury, never make adjustments while the machine is running.
Make sure machine comes to a complete stop before removing or securing workpiece, or workpiece angle.
Ground all tools. If tool is equipped with three-prong plug, it should be plugged into a three hole electrical receptacle. If an adapter is
used to accommodate a two-prong receptacle, the adapter lug must be attached to a known ground. Never remove the third prong.
Remove adjusting keys and wrenches. Form habit of checking to see that keys and adjusting wrenches are removed from tool before
turning it “on”.
Don’t use in dangerous environment. Don’t use power tools in damp or wet locations, or expose them to rain. Keep work area well-lighted.
Keep children and visitors away. All children and visitors should be kept a safe distance from work area.
Make workshop CHILD PROOF with padlocks, master switches, or by removing starter keys.
Don’t force tool. It will do the job better and be safer at the rate for which it was designed.
Use right tool. Don’t force tool attachment to do a job for which it was not designed.
Wear proper apparel. No loose clothing, gloves, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering to contain long hair.
Secure work. Use clamps or a vise to hold work when practical. It’s safer than using your hand and frees both hands to operate tool. Don’t over-
reach. Keep proper footing and balance at all times.
Maintain tools in top condition. Keep tools sharp and clean for best and safest performance.
Follow instructions for lubricating and changing accessories.
Disconnect tools before servicing and when changing accessories such as bits, clamps, etc.
Use recommended accessories. The use of improper accessories may cause hazards.
Avoid accidental starting. Make sure switch is in “OFF” position before plugging in power cord.
Never stand on tool. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted.
Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to ensure that it
will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
Never leave tool running unattended. Turn power off. Don’t leave tool until it comes to a complete stop.
Drugs, alcohol, medication. Do not operate tool while under the influence of drugs, alcohol or any medication.
Make sure tool is disconnected from power supply while motor is being mounted, connected or reconnected.

DB110 Electric - General Operation/Maintenance
7.
Semi-Automatic Electric Foreman DB110 Operation
Entirely electric, no compressed air needed.
Motor rated at 3/4-HP and 8-amps
GENERAL OPERATION (Fig. 7A)
To operate the Electric FOREMAN, first place a workpiece under the
clamping pad. Make sure that the clamping pad extends no more
than 1/8” above the workpiece in the unclamped state. If more than
a 1/8” gap exists, adjust the Clamping Pad to the correct height. See
the “ADJUSTMENTS” section – “Adjusting the Clamping Pad” for more
information. Secondly making sure all body parts and clothing are
safely away from the Clamping Pad, Drill Guide and Drill Bit, pull the
handle towards the work surface. This action will start the Drill Motor
and the mechanical action of moving the Handle will be transferred
to the clamping mechanism to hold the workpiece in position prior to
drilling. Continue to pull the Handle slowly toward the table surface
to complete the drilling cycle. Finish the drilling process by carefully
guiding the Handle back to the starting position. This will stop the
Drill Motor and release the Clamping Pad.
MAINTENANCE (Fig. 7B & 7C)
1. Keep motor clean. Like any electric tool the Electric FOREMAN
needs to be kept free of excessive wood chips and dust. Routinely
remove waste material from inside the cabinet or mount the
machine above an open stand that will not allow the waste
material to accumulate.
2. Lubricate Guide Rods. Periodically service the Guide Rods with
a dry film lubricant like Dri-Tool™ Lubricant from Empire
Manufacturing. A dry film lubricant will not collect wood chips
and dust and will extend the life of the Bearings and the Guide
Rods. See the “ADJUSTMENTS” section – “Changing the Drill Bit”
for more information on how to perform this maintenance. The
mechanical linkage associated with the clamping mechanism
should be lubricated periodically to ensure free movement of
its parts.
3. Use a sharp Drill Bit. You can expect to drill between 4000 and 5000
holes in Oak with your #DKDB drill bit before the bit will need to be
sharpened. This baseline was established using the factory settings
described in the owner’s manual. Adjust your sharpening schedule
for your settings and the material that you may be drilling. Keeping
the Drill Bit clean and free of pitch, resin, and glue will significantly
add to the life of the Drill Bit and increase the number of holes
between sharpening. You can easily clean the Drill Bit with a
proprietary cleaner like Blade Saver™ from Empire Manufacturing.
WARNING! Even a dirty Drill Bit can be very sharp, exercise
extreme caution when handling the cutting edges of the Drill Bit.
After cleaning you can coat the Drill Bit with a proprietary lubricant
designed for cutting wood such as OptiCut-XL™ from Empire
Manufacturing. To change the Drill Bit see the “ADJUSTMENTS”
section – “Changing the Drill Bit” for more information.

preset for 3/4” material. This setting can be changed by moving the
Fence and Clamping Tower along the slots stamped in the Tool Plate.
Be certain to re-adjust the Drill Bit Depth Stop as outlined in the
“ADJUSTMENTS” – “Adjusting the Drill Bit Depth Stop” section of this
manual. Before adjusting the EZ DB Fence make certain your machine
is DISCONNECTED from the ELECTRICAL SUPPLY. Without an electrical
supply you can be certain the machine will not accidentally engage
while you are performing this adjustment.
1. Disconnect the machine from the electrical supply.
2. Loosen each Socket-head Cap Screw on the left and right side
of the Fence using the 1/4” Allen Wrench.
3. Align the Fence perpendicular to the Top Plate for the setting
that corresponds to the material thickness. These settings are
outlined below.
4. Tighten the (2) Socket-head Cap Screws to lock the Fence into
position.
3/4” Setting
This is the standard setting of the Fence to center a screw in 3/4”
material. The Fence is located 5” from the front of the Tool Plate as
shown in the figure below. If necessary adjust the Drill Bit Depth Stop
as outlined in the “ADJUSTMENTS” – “Adjusting the Drill Bit Depth

Adjusting the Clamping Pad Height (Fig. 9B)
The Clamping Pad can be adjusted for material of different
thicknesses. The factory setting will clamp materials of approximate
thicknesses of 3/4”. For materials thicker than 3/4”, the Clamping
Pad will need to be moved upward to allow the material to locate
below the Clamp Pad. For materials less than 3/4” in thickness adjust
the Clamping Pad downward to a gap of 1/8” above the material.
Before adjusting the Clamping Pad make certain your machine is
DISCONNECTED from the ELECTRICAL SUPPLY. Without an electrical
supply you can be certain the Drill Bit will not accidentally rotate while
you are performing this adjustment.
1. Rotate the Brass Lock Nut away from the Adjustment Shaft and up
the Hold Down Bolt to free the rotation of the Adjustment Shaft.
2. Rotate the Adjustment Shaft up the Hold Down Bolt to allow a
1/8” gap above the material under the Clamping Pad.
3. Tighten the Brass Lock Nut against the Adjustment Shaft to
prevent the accidental movement during normal drilling operations.

Adjusting the Clamping Cylinder Height (Fig. 13B)
The Clamping Cylinder can be adjusted for material of different
thicknesses. The factory setting will clamp materials of approximate
thicknesses between 1/2” and 3/4”. For materials thicker than 7/8”,
the Clamping Cylinder will need to be moved upward to allow the
material to locate below the Clamp Pad. Before adjusting the
Clamping Cylinder make certain your machine is DISCONNECTED from
the AIR SUPPLY. Cycle the machine via the Handle to remove air from
the system. Without an air supply you can be certain the Clamping
Cylinder will not accidentally engage or the Drill Bit will not rotate
while you are performing the adjustment.
1. Loosen the (2) 1/2” nuts located on the rear of the Clamping Tower.
2. Adjust the Clamping Cylinder to allow a 1/4” gap above the material
under the Clamp Pad.
3. Tighten the (2) 1/2” nuts to lock the Clamping Cylinder in position.
Automatic Oil Lubricator (Fig. 13C)
An Automatic Oil Lubricator is provided to maintain proper lubrication
to the pneumatic motor. The Automatic Oil Lubricator is preset at 1/2
turn open. The oil level in the Air System Lubricator should be routinely
checked and refilled with air motor oil comparable to the oil provided.
Normal use of the machine will cause a light film of oil to accumulate on
the back on the machine cabinet where the pneumatic motor exhausts.
To increase the amount of oil added the system turn the Adjustment
Screw counter-clockwise. Likewise to decrease the amount of oil added
to the system turn the Adjustment Screw clockwise. Make certain
your machine is DISCONNECTED from the AIR SUPPLY when filling the
Automatic Oil Lubricator. Cycle the machine via the Handle to remove air
from the system.
