INSTALLATION
INSTRUCTIONS
Refer to figure 2 on the previous page as well as the
parts lists and drawings in the back of this manual for
partidentification and orientation, if necessary.
All guards and instruction plates are installed for your
safetyandinformation andmustremain onthemachine
asshipped fromthe factory.
UNCRATINGTHEPAPERDRILL
This machine is shipped on a wooden skid and is en-
closed with a protective corrugated cover. It is held
onto the skid with plastic straps. Remove the straps
and carefully cut the corrugated cover down the side
andunwrapitfromaroundthemachine. Thetable,back-
gauge, and other accessories are packed in separate
boxesand are securedto the machine. Remove these
and carefully position the machine on the floor. Imme-
diatelyafteruncrating, check offpartsreceived against
the packing list. Also, examine for any physical signs
of damage incurred during shipping. The machine is
inspectedbefore andafter itis cratedat ourplant. The
responsibility for filing a claim against the carrier for
damages incurred during shipment rests with the re-
ceiverof goods (FOBour factory).
Cleanall partswith acommercial cleaning solvent be-
fore installing or using the machine.
INSTALLINGTHETABLEAND BACKGAUGE
Locatefour(4)tablemountingboltsshippedinthe back-
gaugebox [(2) 5/16-18x 1” shoulderbolts; (2)¼-20x 1-
3/4”carriagebolts]. Thetwocarriageheadboltsgointo
thereartablemountingholesandthetwo shoulder bolts
go into the front mounting holes. Mount the table, but
leavethe hardware loose. Slidethe backgauge on the
table and align the backgauge face to the 1” mark on
both of the scales; fasten the backgauge to the table
with the thumbscrews provided.
Next, position the table so that the face of the back-
gauge measures exactly the same distance from the
front of each pull down shaft (fig 3). When this is ac-
complishedtighten the tablemounting hardware.
FINAL INSTALLATION
Place the drill block knock-outs in position. Now set
the three drill blocks place. Check to see if the blocks
are flush with the table. Place shims under the blocks
if necessary.
Insert the tapered head of the hollow drills into the
spindles. Besure that the drift holecovers are in place
beforeoperatingthemachine(fig 2). The driftholecov-
ers prevent paper chips from flying out while drilling.
Check the level of the oil in the hydraulic reservoir.
Thischeckismadebyfirstremovingthelouveredpanel
at the left side of the stand (two screws hold it in place)
and locating the breather cap on the top of the reser-
voir. The breather cap has a dip stick attached for
checkingthe oil. When screwed in (and then removed
tocheck) there shouldbe approximately an1/8” (3mm)
ofoil on the stick. Some machinesare equipped with
a clear reservoir in which case the oil level can be
checked by visually inspecting the oil level. There is a
fulllevel line marked on thereservoir. Recommended
oilsare found inthe maintenance sectionof thismanual
(pg. 23).
HOOKING UP THE POWER LINE
The EH-3C is factory wired for 208/230 Volt, 1 phase,
50/60 hz. operation. It is the customer’s responsibility
to wire the machine for the rated voltage using a 30
Ampcircuit(minimum). Therecommendedcircuitover-
load protection device should be 20 Amps. The rec-
ommended wire size for this hookup is #10 gauge.
Itisimportantthattheproperlinevoltagebemaintained.
Failure to do so will result in improper operation of the
machine(seethetroubleshootingsectionofthismanual
(fig. 3)
CAUTION: Always disconnect the
power when cleaning, servicing, or
lubricatingyour drill, see Lock OutPro-
cedures, pg. 4.
CAUTION: Always handle drills with
care to avoid severe lacerations. Even
dull drills are sharp enough to cause
lacerations.

forspecific problems). It may be necessary to provide
a separate branch power line for the machine.
Since the standard machine is intended for a single
phase hookup, simply fasten either wire of the power
cordto either terminalof thestarter and theground wire
tothedesignated terminal (fig.4).
INSTALLINGTHE CHIP BAG
The chip container bag is installed by slipping it over
the two hooks provided on the rear of the machine.
OPERATING
INSTRUCTIONS
STARTINGTHEMACHINE
The power for this machine is supplied by two motors;
one is for the hydraulic power pack, the other is for the
spindle. They are both started and stopped simulta-
neously by a single set of start-stop buttons located on
the stand under the table (fig. 1). Be sure both motors
are operating before trying to drill paper.
OPERATINGTHEDRILL
Pressingdown on thefoot switch activates the hydrau-
lic unit which brings the drill heads down through the
stock. Whenthe drillsreach thebottom oftheir stroke,
they will automatically return the “up” position. (Note:
Thevertical strokeof thedrills mustbe setbefore drill-
ing to provide the proper drill depth. See the following
sectionforadjustment procedures). Thepedalmust be
released and depressed again before drilling the next
setof holes, assuringfull control andallowing norepeat
stroke. By releasing the pedal, the operator can stop
the drills in their downward stroke at any time allowing
them to return to their normal position, thus preventing
costly errors. NEVER REST YOUR FOOT ON THE
TREADLEWITHOUTINTENDING TO BRING DOWN
THE DRILLS!
ADJUSTINGTHEVERTICALSTROKE
Theverticalstrokeofthemachinedeterminestheexact
depth the drills will reach at the bottom of their stroke.
Wheneverinstallinganewsetofdrills,thevertical stroke
mustbe adjustedbefore drilling.
The two outside heads are provided with independent
heightadjustmentwhile the centerheadworksfrom the
center overall adjusting screw. This is necessary be-
cause of the variance in length of the drills. Start by
adjusting the center head to its highest point. This is
accomplishedbyturningthedrilldepthadjustmentscrew
(fig. 2) counterclockwise until it stops turning. Then
adjust the side heads all the way up by turning the
knurled ring on the heads clockwise (use the provided
drill drift in the holes if necessary). Now, with the new
drills in the place, put two or three sheets of paper un-
der the heads. The center spindle should then be ad-
justed so that the center drill just cuts through the pa-
per. Too deep will cause a ragged hole in the bottom
sheetsas wellas ashorter drilllife fromdrilling intothe
cutting block. After the center drill is adjusted, each
outside spindle can be adjusted. Turn counterclock-
wise to lower and clockwise to raise. No locking is
necessary. Once all three drills are set, drill through a
full lift of stock. A final adjustment of the drill depth
adjusting screw may be necessary to obtain the best
results.
ADJUSTINGTHECENTERTOCENTERDISTANCE
BETWEENDRILLHEADS
This machine incorporates three drilling heads operat-
ing on three belt-driven spindles. The center head is
stationary while the two outside heads have a lateral
adjustment of 13/4” each.
This provides an adjustment range of 23/4” to 41/2” (7
cm to 11 cm) between the center drill and either of the
outsidedrills, or a range of 51/2”to 9” (14 cm to 23 cm)
between the two outside drills.
The lateral adjustment is accomplished by loosening
the clamp knob (a black, plastic hand knob) located at
the rear of each outside head, and then turning the 4-
lobed, black knob located at the outside of each head.
Thismovestheheadsalongashaft.Ascaleandpointer
located at the front of the heads gives a reading in
inchesand millimeters ofthe center line relationship to
the center head. When a setting is made, make cer-
tain that the clamp knob is tightened again.
(fig. 4)

F.352-J/EH-3C DRILL/JUN 98
Any combination of three heads can be used, that is
one, two, or three holes may be drilled if desired. It is
recommended,howeverthatnomorethan two half inch
hollow drills be used at the same time.
ADJUSTING THE BACKGAUGE POSITION
The backgauge position is adjusted by first loosening
the two thumb screws under the table. This will allow
thebackgauge to movefreely. Then usethe two scales
on the top of the table to set the backgauge to the de-
sired position. The scales read in inches and millime-
ters and will give the distance from the edge of the
sheet to the center of the holes. Be sure the 1” (2.5
cm) square pieces mounted to the backgauge are
alignedon top of the scales to providethe proper read-
ing (fig. 2). Tighten the thumbscrews when finished.
USING THE SIDE GUIDE
To adjust the position of the side guide, loosen the two
black knobs until the side guide is free to slide side-
ways. Slide the side guide to the desired position and
thentighten the twoknobs. For certain hole positions,
it may be necessary to remove the rectangular spacer
from the side guide assembly (fig. 5).
ADJUSTING THE STROKE SPEED
Thehydraulic unitis equippedwith an adjustable valve
forregulating the speedon the drillstroke (up anddown
travel). Soft stocks such as mimeographs, etc., are
aptto wrinkle athigh speeds, andthe speed shouldbe
set to a point where the best results are obtained.
Thisadjustmentis made byturningtheadjustable valve
(located on the right side of the drilling machine stand)
counterclockwiseto reduce speed and clockwise to in-
crease speed (fig. 6)
(fig. 5)
REMOVING THE CUTTING BLOCKS
Each cutting blocks is removed by inserting your fin-
gers in the hole provided in the frame (under the table)
and pushing up on the cutting stick knock out. There
arethree holes;one on eachside ofthe frameand one
in the front.
REMOVINGDRILLS FROM THE SPINDLE
Remove the drift hole cover from the spindle to ex-
pose the drift hole. Then, with the flat side down, in-
sert the drill drift into the hole and lift upward. The
upward movement forces the drill down and releases
it from the spindle.

DRILLING TIPS
Important! To prevent the drill from overheating, always avoid drilling too slowly. The drill stroke speed should
be set at the fastest speed possible that still allows the drills to cut easily 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” (1.3 cm) 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
oftime, particularly on long runjobs.
Keep Drills Sharp - A dull drill is the major cause of drill breakage and production tie-ups. Usually after three
hoursof drilling,depending onthe typeof paperbeing processed,the drill should be sharpened. A dull drill results
in poor quality work.
Keep Drills Clean - A dirty and rusty drill will not permit the free upward passage of the drill chips. Pressure built
upby aclogged drill will split or break thedrill. To keepit freefrom dirt or rust, clean the drill of all chips after each
use and apply a light oil to the inside and outside. Drills should be cleaned out immediately after each use. This
isparticularly trueif acoated orvarnished stockhas beendrilled. On thesejobs thecoating onthe chipsfrequently
fuse the chips into one solid mass when the drill cools, causing breakage the next time the drill is used.
Lubricate Drills - Lubrication assists in the passage of the chips and helps avoid overheating of the drills. Use
readilyavailable stick lubricantsfor this purpose. Hold the endof the stick against the side of therotating drill. Be
sure to touch the cutting edge with the lubricant also. Wipe off excess oil before drilling. CAREMUSTALWAYS
BETAKENWHENHANDLINGDRILLS.
Keep Spindle Clean - Cleanout thedrill spindle frequently. This will prevent any buildupin thespindle of the drill.
Set the Drills Correctly - Do not cut too deeply into the cutting block. The drill should just touch the block and
cleanly cut through the bottom sheet. During drilling, do not set the drill deeper into the block but change the
position of the block frequently. Drilling deeper into the block dulls the drills quickly. Use a piece of chipboard
underneath your stock. This will make handling the stock easier and will ensure that the last sheet is cut cleanly
through.
Check for Drill Wobble-Ifspindles are badlyworn or bentthrough misadjustment,have them replacedimmedi-
ately. A wobbly or loosely held drill can break.
Check Your Drill Sharpener - The cutting edge of the sharpening bit should be inspected frequently to make
certain that it is sharp and free of nicks. Never let a drill drop onto the sharpening bit. It will chip the sharpening
edge. Usegentle pressure when sharpening - let the sharpeningbit do the work. Check thesharpness of thedrill
aftersharpening. The cutting edgeshould be razor sharp.
Check Belt on the Drilling Machine -Thebelt should be kept tight toassure properspeed ofthe drill. When the
drill slows down, it acts more like a punch which results in poor quality work and drill breakage.
Justalittle time andeffort taken witheachuse of yourpaperdrilling machineshouldresult in troublefreeoperation
overmanyyears.

OPTIONAL AUTO-TRIP BACKGAUGE
Thisoptional backgauge assemblyprovides additional
versatilityto theEH-3C. The automatictrip onthe side
guide permits step and repeat type of operation with a
minimum distance between holes of3/8” (9.5mm) with
the standard stops or 1/4” (6.3 mm) minimum by the
use of a fixed gage, available as optional equipment.
As each set of holes is drilled, the side guide is auto-
matically tripped, and as soon as the drills clear the
stock on their up stroke, the guide is free to move to its
next stop. This is accomplished by pushing the stock
totheleftandmovingtheguideatthe sametime. When
drilling one, two or three holes only, that fall within the
9” (23 cm) limitations of the machine, the automatic
trip bracket (located at the left of the machine) can be
turned so that it does not engage the trip lever.
SETTING THE SIDE GUIDE STOPS
First set the rear gage to the desired back margin. Be
sure both sides are set to the same dimension and
tighten the two thumbscrews. Next, remove the guide
shaft and set the guide stops to the desired distance
betweenholes (a scalein theguide shaft isprovided for
this purpose). The guide shaft is then replace in the
rear gage and final adjusting or centering of holes is
accomplished with the knurled screw at the extreme
leftend of the guide shaft.
The automatic trip gage comes equipped with seven
stops. Additional stops can be purchased at a very
nominalprice. Challengefixed index gagesarerecom-
mendedwhere the samejob is tobe handled overand
over again. They are easily and quickly attached and
removed. NOTE: Whendrilling narrow strips,the side
guideroller assemblyshould bemounted on the inside
of the side guide assembly.
