7.0 Operation
19
Adjust the handwheel on the top of the machine clockwise until one drill bit starts to drill through.
Next, adjust the remaining drills individually with the adjusting knob on top of each drill head until all
of the drills just cut through the sample. It may be necessary to adjust the handwheel slightly when
drilling a full lift of stock.
The handwheel must turn with a little friction. Adjust the friction by tightening the setscrew in the up-
per front of the dovetail. (See Main Assembly – Front View, Ref. no. 45,46 & 47).
7.4 POSITIONING THE DRILL HEADS
The drill heads can be adjusted to a minimum center-to-center distance of 1 ¼"(3.2cm) and a maxi-
mum of 21"(53cm). To adjust the heads for the desired hole spacing, lift the top cover, locate and
loosen the socket head cap screw that clamps the head to the dovetail. Slide the head to the re-
quired position using the provided scale, and tighten the clamp screw.
The MS-10B is capable of up to ten standard drill heads; or two triple drill heads; or two large-hole
drill heads. When using standard drill heads or two triple heads, it is recommended that no more than
five half-inch drill bits be used at one time.
7.5 POSITIONING THE BACKGAUGE
The backgauge is positioned by aligning the front edge of the backgauge with the scale that is
imbedded in the table. The scale will give you the dimension from the back of the sheet to the center-
line of the holes. After the backgauge is positioned, lock it in place with the two knobs provided. To
drill less than 1" (25mm) from the edge of the sheet, two filler blocks (provided) must be used. The
blocks attach to the face of the backgauge and are locked in place with thumbscrews. The blocks will
add 1" to the face of the backgauge, remember this when using the table scale to set the position of
the backgauge. Example: To drill ¾" (19mm) from the edge of the sheet, install the filler blocks and
set the backgauge to 1-3/4" (4.4cm) on the scale.
7.6 EMPTYING THE DRILL CHIP BIN
A large capacity chip bin, located on the front of the machine below the table, is removed by sliding it
forward and using the two cut outs in the side of the bin, lifting up, and removing the bin. The bin is
safety interlocked. If it is removed while the machine is running, it will shut off. The bin must be in
place for the machine to be restarted.
7.7 TOOL STORAGE
A convenient tool drawer is provided under the table for storing tools, drill bits, etc.
7.8 DRILLING TIPS
Important! To prevent the drill from overheating, always avoid drilling too slowly. The drill should be
brought down as rapidly as possible allowing the drills to easily cut through the paper.
Slotted Holes - Instead of punching slotted holes for five and seven-hole universal binding work,
save time and cost by drilling a 1/2 inch diameter hole in place of the slot. The slot is only intended to
allow the post or ring to be used in either location, and the large hole permits this.
Plastic Bindings - Drilling holes for plastic bindings, instead of punching them, is practical and saves
a great deal of time, particularly on long run jobs.
