Drill Unit Selection
The DK4100 and DK5100 machines were designed for multiple
pocket hole drilling for applications normally associated with car-
cass construction. The DK4100 will drill up to four pocket holes at
8-inch centers across a 24-inch span. The DK5100 will drill up to
five pocket holes at 6-inch centers across a 24-inch span. Each of
the Drill Units can be independently selected via the Drill Unit Se-
lector Switch. This simple “ON/OFF” switch will enable or disable
the associated Drill Unit’s operation. By selecting Drill Units to
“OFF” that Drill Unit will not actuate during the drilling cycle. This
option will allow the operator to vary the pocket hole spacing in
increments of 6-inch and 8-inch spacing depend on the model.
For example: two pocket holes may be drilled spaced 8-inches
apart on the end of a 12-inch wide shelf by switching two Drill
Units to “OFF” on a DK4100 machine. Another example would be
to drill four pocket holes in a 28-inch panel with two holes spaced
2-inches from the each end and 6-inches apart by switching the
middle Drill Unit to “OFF” on a DK5100 machine.
Swing Stops
Two Swing Stops are provided to assist in drilling pocket holes in
the same location on multiple work pieces of the same dimension.
When the Swing Stop is not used, it will pivot out of the way to al-
low the work piece to slide underneath and rest against the fence.
To change the location of the Swing Stop simply loosen the Knob,
move to the new location and tighten the Knob to lock the Swing
Stop in position.

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. 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.
