6.0 Installation Guide
Refer to the parts lists and drawings in the technical manual for part identification and orientation, as
necessary.
All guards and instruction plates are installed for your safety and information and must remain on the
machine as shipped from the factory.
6.1 Uncrating the Paper Drill
Unless otherwise specified, this machine is shipped in a wooden crate completely assembled. The
machine should be unpacked by carefully removing the wood so as not to damage any of the ma-
chine parts. It is held onto the skid with lag bolts through the inside of machine frame. Remove the
lag bolts and carefully position the machine on the floor. The machine can be safely be picked up by
sliding the forks of a fork lift under the base of the machine or by removing the chip drawer and sliding
the forks under the chip drawer slide brackets (take care not to hit or damage the hydraulic unit in the
rear of the machine). Immediately after uncrating, check off parts received against the packing list.
Also, examine for any physical signs of damage incurred during shipping. The machine is inspected
before and after it is crated at our plant. The responsibility for filing a claim against the carrier for
damages incurred during shipment rests with the receiver of goods (FOB our factory).
Clean all parts with a commercial cleaning solvent before installing or using the machine.
6.2 Power Hook Up
Always disconnect the power when cleaning, servicing, or lubricating your
drill, see Power Lockout Procedure page 4.
For satisfactory operation, be sure that your machine is wired for the correct phase and voltage and
has adequate power. The correct electrical specifications for your machine are shown on the serial
plate. Check the machine serial plate before connecting the power. There is a junction box located
on the left side of the machine with wires for power and a ground lug. After connecting power, briefly
start and stop the machine and check motors for proper rotation. If incorrect, disconnect the power
and switch any two leads coming to the machine.
Watch Setup Voltage- Inadequate power to the machine can be a major source of problems. Too
many machines on the same circuit will reduce the power to each machine. Inadequate voltage will
frequently cause overheating, loss of power, and in extreme cases, failure to operate. Test your volt-
age when the shop is at actual working levels. Challenge recommends a dedicated line with a lock-
able disconnect to provide adequate power for this machine.
SHOCK HAZARD! Always disconnect power at main power panel be-
fore working on the machine. Lock it out to prevent accidental power up. (See Power Lockout
Procedure page 4).
Important: You must have an adequate size circuit and heavy enough wiring for this machine. The
circuit size should be a minimum of 20% greater than the amperage rating on the machine name-
plate. If a wire is run over 75 feet (23 meters), the next size wire should be used. Check local electri-
cal codes.

6.0 Installation Guide

6.2.1 Three Phase Hook-Up
1. Disconnect the power at the main power panel and lock it out to prevent accidental power-up.
See Power Lock-Out procedure, page 4.
2. Thread the power cord through the knock-out hole in the junction box located on the left hand
side of the machine. Secure it with a conduit connector.
3. Fasten the ground lead to the ground terminal lug found in the junction box.
4. Use wire nuts to join the three power leads to the L1, L2 and L3 leads found in the junction
box.
5. Close all doors and guards, unlock the main power and switch it on. Turn on the Main Power
Disconnect Switch located under the table on the front of the machine. The machine should
now have power.
6. Depress the start button to activate the motors and check to make sure that they are turning
the same direction as the arrow on the motor casing. If they are not, disconnect the power
and simply exchange any two leads of the power cord as soon below. The motor will now
turn the correct direction. Double check to make sure.

6.3 Controls
The control panel is mounted on the top left of the
machine.
The blue TABLE LIGHT push button turns the table light
on and off.
The green START push button turns the spindle and
pump motors on.
The red STOP push button will shut both motors off.
The MS-10B drill is equipped with a safety interlock system that prevents the machine from being run
with the chip drawer removed or the spindle guard up. Also, if the cover is raised or the drawer
opened while the machine is running, the motors will shut off and the machine will have to be re-
started when the drawer and/or cover are back in place. This is a safety feature provided to prevent
accidental contact with moving parts and must not be tampered with.
6.4 Vertical Speed
The vertical speed of the drilling head is adjusted with
a control knob on the front of the machine under the table.
This valve regulates the speed of the drill's downward
travel. Light or soft stocks such as mimeographs, etc. are apt
to wrinkle at high speeds, and the speed should therefore, be
regulated to a point where the best results are obtained
.
This is found mostly be "trial and error"
Also, too slow speeds will cause the drill to "burn" through the
paper. If burning or burnishing occurs, either increase the vertical speed
and/or sharpen the drill bits. Slower vertical speeds are recommended
when drilling with the maximum number of heads.
6.5 Assembly
Always disconnect the power when cleaning, servicing, or lubricating your
drill, see Lock Out Procedures, page 4.
The only assembly required is to insert the drill blocks and side guide onto the table and mount the
drill heads in the machine.

6.0 Installation Guide

Swing the front cover back unit it rests on top of the machine. Loosen the drill head clamp located on
the back of the drill head. Place the head on the dovetail of the drill and slightly tighten the clamp
screw. Position the head by sliding it along the dovetail and then aligning the drill head indicator with
the scale and tightening the clamp screw. (Figure 7)
Figure 7
Insert the spline shaft through each head (you may have to rotate the spline to align the it with the drill
head gear) until it seats in the left hand spline bearing. The spline must go in far enough to enable
the spline lock ring to secure the spline shaft pin. Insert the spline pin into the lock ring and rotate to
lock. (See Figure 5,on page 15) Close and secure plastic cover.
6.5.3 Mounting the Side Guide
The side guide is mounted to the table with the two cap screws provided. It can be positioned as nec-
essary along the line of mounting holes in the table. After it is positioned, the guide plate can be ad-
justed by loosening the knurled lock nut and turning the micro-adjust knob. (Figure 8)

6.5.4 Installing/Removing the Hollow Drills
Always handle drills with care to avoid servere lacerations. Even dull drills
are sharp enough to cause lacerations.
TO INSTALL : Insert the tapered head of the hollow drill into the spindle. Press the drills firmly into
place so they do not fall out when the machine is started.
To prevent the drill chips from flying out, be sure that the drift hole covers (black spring bands) are
over the drift holes in the spindle. (Figure 9, below)
TO REMOVE : Slide the drift hole cover to expose the drift hole in the side of the spindle. Insert the T
-handle drill drift into the hole with the flat side down and lift up. (It may be necessary to also twist the
handle.) (Figure 10,below)

7.0 Operation
7.1 STARTING THE MACHINE
Two motors supply the power to the machine: one is for the hydraulic pump, the other is for driving
the drill spindles. Both motors are simultaneously controlled by the start and stop buttons located on
the top left of the machine. ( See Controls, pg. 13) Make sure both motors are running in the proper
direction before trying to drill paper.
Never rest your foot on the foot pedal without intending to bring the
drills down!
Replace all guards. Do not operate this machine with any guards
removed. Severe personal injury could result.
Always wear safety glasses when operating this machine.
Note: the MS-10B drill is equipped with a safety interlock system which prevents the machine from
being started with the chip drawer opened or the front plexiglass cover up. If the chip drawer is
opened or the cover raised while the drill is in operation, the machine will shut off and the drills will
return the full up position. After the cover or drawer is put back in place the machine can be
restarted. This is a safety feature to prevent acccidental contact with moving parts and must not be
altered.
7.2 OPERATING THE DRILL
After the machine is turned on, depressing the foot switch will bring the drill heads to the table. When
the drills reach the bottom of the stroke, the drills will automatically return to the full up position.
(Note: The vertical stroke of the drills must be set before drilling to provide the proper drill depth. See
section…7.3). The foot switch must be released and depressed again before drilling the next set of
holes, assuring full control and allowing no repeat stroke. By releasing the foot switch the operator
can stop the downward travel of the drills at any time allowing them to return to their normal position,
thus preventing costly errors. 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. The drill heads are
mounted on a dovetail in the machine and are turned by a belt driven spline shaft.
7.3 ADJUSTING THE VERTICAL STROKE
The vertical stroke of the machine determines the exact depth the drills will reach at the bottom of
their stroke. Whenever installing new drills, the vertical stroke must be adjusted before drilling.
After the drill heads are installed, raise the drill heads to their full up position by turning the handwheel
on top of the machine counter-clockwise until it stops. Raise the individual drill heads all the way up
by turning the knurled knob on top of the heads counter-clockwise until they stop. After you inserted
the drills, place a couple of sheets of the stock you are drilling on the table under the drills. Start the
machine. Depress the foot switch, at the bottom of the stroke the drills should not be drilling through.

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.
