Adjusting the Clamping Cylinder Height
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 and/or
ELECTRICAL SUPPLY. Cycle the machine via the foot switch
several times to remove air from the system. Without an air
supply or electrical supply you can be certain the Clamping
Cylinder will not accidentally engage or the drill bit will not
rotate while you are performing maintenance.
Step 1: Loosen the (4) Socket-head Cap Screws (two on
each side) located on the Clamping Cylinder Bracket.
Step 2: Adjust the Clamping Cylinder to allow the material to
pass under the Clamp Pad.
Step 3: Tighten the (4) Socket-head Cap Screws to lock the
Clamping Cylinder in position.

Clamping Duration Control
Clamping Duration Control allows the user to adjust the
duration that the pneumatic clamp engages the material
before, during, and after the drilling operation is performed.
The factory setting of this valve will maintain the correct
amount of time that the material is clamped while drilling. If
the work piece lifts off of the Drill Guide Plate during drilling
then the Clamping Duration Control will need to be adjusted.
Loosen the Locking Collar and turn the Screw in the
clockwise direction to increase the duration (more clamping
time). Turning the Screw in the counter-clockwise direction
decreases the duration (less clamping time). Make certain
to tighten the Locking Collar to prevent the Screw from
accidentally drifting or vibrating out of adjustment.

Feed Rate Flow Control
The Feed Rate Control Valve allows the user to adjust the
speed at which the drill bit advances into the material. The
factory setting of this valve will maintain a consistent feed rate
for various thicknesses of different materials to optimize Drill
Bit life. The Feed Rate Control Valve should only be adjusted
when a faster or slower rate of Drill Bit feed is desired. This
adjustment is only recommended for experienced users
that consistently drill the same thickness of the same type
of material on a daily basis. The Feed Rate Control Valve
is adjusted by loosening the Locking Collar and rotating the
Screw in the direction of the desired change in feed rate. “F”
corresponds to a Faster feed rate, “S” corresponds to a Slower
feed rate. Make these adjustments carefully as only a slight
change in position will result in a large change of feed rate.
Make certain to tighten the Locking Collar to prevent the Screw
from accidentally drifting or vibrating out of adjustment. If you
have changed the setting on the Feed Rate Control Valve and
want to put it back to factory settings, please follow these simple
directions to do so. Turn the locking collar (counter-clockwise) to
loosen it up, then tighten the screw all the way down (clockwise)
to start over. To reset it to the factory setting, turn the screw
(counter-clockwise) 4 complete turns for our DK1100 FE
machine and 3 complete turns for our DK3100 machine. Then
tighten the locking collar back down (clockwise) to prevent the
Screw from accidentally drifting or vibrating out of adjustment.
