983001 8370 EWC8370 8318 Issue May 2007 Page 5
1) Installation:
Locate a clear work area 24” wide X 30” deep. The work area must be a solid
and firm cabinet or a heavy duty table with a flat level surface.
EWC-8370:
The EWC-8370 requires an outlet within 5 feet that provides a
15-amp service (16-amp European) which is protected at the
customer’s circuit box. Never attempt to move the EWC-8370 with
one person! Always move your EWC-8370 with two people, one
on each end. To mount your EWC-8370 to an OD or HD vertical punch (except
HD-7500) will require an optional mounting kit. Contact your dealer for the kit that
fits your punch model and follow the instructions inside the kit. The EWC-8370
comes as a stand-alone machine and is ready to operate after setup.

Attach the closing handle with the zinc colored screw, washer, and nut
(with the two wrenches provided) with the nut on the back side of the handle and
the Closing Bar in the UP position. The HC-8318 is ready to operate after setup.
HD-8370:
Attach the closing handle with the zinc colored screw, washer, and nut
(with the two wrenches provided) with the nut on the back side of the handle and
the Closing Bar in the UP position. The HD-8370 can be operated in the stand-
alone or mounted to an OD or HD vertical punch (except HD-7500) as a module.
To mount your HD-8370 to an OD or HD vertical punch will require an optional
mounting kit. Contact your dealer for the kit that fits your punch model and follow
the instructions inside the kit.
2) Machine Specifications:
The maximum book length is 14” (356MM) (HC-8318 up to 18”, Euro A3)
down to a minimum of 5-1/2”, Euro A6. Book stops are placed at the 5-1/2”,
Euro A6, 8-1/2”, Euro A5, 11”, Euro A4 & 14”, and Euro 13” positions. The
book stop positions are placed at the most common book lengths, although
any size book can be bound from 14” (18” HC-8318) down to 5-1/2”. See
chapter 3) Punching Requirements, for exact hole specifications.
3) Punching Requirements: The correct punch hole patterns must to be
used in order to provide a clear path for the wire as it is closed into the
book. All 3 machines require a 3-1 pitch hole pattern, which measures 3
holes to every inch.
Hint: The size and placement on the sheet is also important. If the size of
the hole is smaller, or if the placement of the hole is not in the correct
position, the wire may have a problem closing into the holes of the book.
The following sizes are standards and are manufactured by Performance
Design Inc. for the Rhin-O-Tuff line of paper punch machines.

983001 8370 EWC8370 8318 Issue May 2007 Page 6
The size of hole for all 3 machines should be 11/64” (.172) round (or
larger) or 5/32” (.156) square. The Margin or Backspace for is .168” for
round and .179” for square holes.
4) Setup Guide, STEP 1 through STEP 10; The HD-8370 has a setup guide
intended to make binding easy for new and experienced users. Simply follow
steps 1 thru 10 for the perfect bind. These steps are labeled on the machine
in a simplified format. It is recommended that the first time you use the
machine to follow both the manual and labeled steps on the machine.
Numbers/letters and colors are used to link together same-function or adjust-
this to-that relativity. For instance if you are at 2A, look for 2B on the
machine. Both 2A and 2Bs are colored the same to make their location easy
to find. In 2A and 2B’s case there are two sets as noted on the label. If it’s
not noted do not look for a second set. Before continuing, reset machine
to be consistent with the manual, start with the Book Stops (1) in the
FORWARD most position. Unlock the STEP 4 center winged knob (2),
turn the outer knob until the Book Stops are FORWARD, re-lock the
center knob. Place Upper Wire Guide (3) in UP Position with the Closing
Handle (4) in the Back Position, shown
here.

983001 8370 EWC8370 8318 Issue May 2007 Page 7
STEP 1, Determine the correct wire size for a book: See figure 1.
Determine the correct wire size by placing the book to be bound including
covers into the best fitting slot located on the book table. If the book seems
too tight in the slot, always use the next larger size wire. Once you have
determined which slot fits the book best, note the Wire Number, for example
Wire No.4 , for will be used in this manual.
Fig. 1
You can also use the table below to determine the correct wire size for the
book thickness. Covers are not included in the number of sheets column. This
setup guide uses Wire No. to setup the entire machine. Once you have
determined the Wire No. keep it in mind for the rest of the setup.
Wire Diameter Book Thickness Number of sheets
Inch mm No. Inch mm 20lb 80gsm
1/4 6 43/16 4.8 45
5/16 8 51/4 6.4 65
3/8 10 65/16 7.9 80
7/16 11 73/8 9.5 95
1/2 12 87/16 11.1 110
9/16 14 91/2 12.7 125
STEP 2A & 2B RED, Adjust Closing Bar: See Figure 2, next page.
With the closing handle in the BACK position (EWC-8370 in its normal up
position), adjust the Closing Bar by turning BOTH Adjustment Knobs
simultaneously to the wire number determined in STEP 1 to Both labels 2B.
The Closing Bar Adjustment Knobs have a UP/DOWN turning Indicator as
well as a Position Line. The Position Lines are visual aids to help maintain
parallelism between the Closing Bar and the lower closing bar. Simply turn
the Closing Bar Knobs simultaneously keeping the Position Lines in sync.
Wire varies from any two manufacturers and in rare cases you may need to
lower or raise only one end of the Closing Bar for a consistent close from end
to end. Adjust the upper closing bar to setting No. 4 as shown in Figure 2 next
page.

983001 8370 EWC8370 8318 Issue May 2007 Page 8
Fig. 2
STEP 3A & 3B BLUE, Adjust Lower Closing Bar: See Figure 3.
Locate Both Step 3A decals on both sides of the machine in Fig. 3 balloon
(1). Adjust the Closing Lower Bar Knobs located behind the machine to the
Wire No. 4 Position of the 3B (2) decals. This is the recommended start point
of No.4 and 5 wires. Further adjustments may be required here, but for now
follow the steps in order.
Fig. 3

983001 8370 EWC8370 8318 Issue May 2007 Page 9
STEP 4 GREEN, Adjust Wire Rest: See Figure 4.
Locate Step 4 decal only on the left side of the machine (1). Adjust the Step 4
Knob by unlocking the center winged knob then turn the outside dial so that
the Wire Rest (2) aligns with the appropriate Wire Number on decal 4B shown
in Fig.4 (3). Lock the center winged knob.
Fig. 4
STEP 5A & 5B YELLOW, Adjust Book Stop: See Figure 5.
Locate the Book Stop Adjustment Knob 5A (1) only on the left side of the
machine. Unlock the center winged knob and turn the outside dial until the
Book Stops (2) and Book Stop Indicator Pin (3) align with No.4 on the
Adjustment Decal 5B (4). Lock the center winged knob.
Hint: If the holes are not punched in the standard position relative to the
edge of the book (.168” for round, .179 for square), the book stop
adjustment knob may have to be moved from the normal setting.
Fig. 5

983001 8370 EWC8370 8318 Issue May 2007 Page 10
STEP 6, Load Wire: See Figure 6a.
Place a piece of wire to be closed into the book load area with the wide loop
facing down (1).
Fig. 6a
See Figure 6b. Place the first loop on the left side of the wire in-between the
twin book stops on the left side of the machine.Place the last loop of wire just
to the right of the book stop next to the appropriate last loop position.
Magnets will hold the wire in place; lightly press the entire length of the wire
down against the bottom closing bar.
Hint: Any wire length from 14” (18” for the HC-8318) down to 5-1/2” can
be used. If you are using a nonstandard length, place the first loop on the
left side of the wire into the twin book stop position as you would normally
do and let the end loop fall freely into the closing tool. The only time you
may run into a problem with nonstandard lengths is if the wire is
manufactured under or over pitch by a substantial amount.

983001 8370 EWC8370 8318 Issue May 2007 Page 11
STEP 6, Adjust Table Height: See Figure 6c.
Locate the table height adjustment knob (1) only on the left side of the
machine, unlock center winged knob and turn the outside dial until the wide
loops of wire are slightly below table’s edge. As shown in Figure 6c Cross
Section. Lock the center winged knob.
Hint: The purpose of the book table is to support the book and guide the
bottom covers or sheets of the book into the wire. Some fine adjustment
may be necessary if some of the bottom covers or sheets are not located
in the closed wire after the book has been bound. At eye level to the book
table, move the book table as described above until you cannot see the
wide loops above the table.
Fig. 6c
(Blank)

983001 8370 EWC8370 8318 Issue May 2007 Page 12
STEP 7, Upper Wire Guide: See Figure 7.
The Upper Wire Guide, when fully rotated down, (1) hides the narrow loops
(2) of the wire, adjust until the narrow loops of the wire are hidden (3) with the
Wire Guide in the down position. Loosen the pivots on both ends (4) (Black
levers on the EWC-8370) and adjust the Upper Wire Guide (1) up or down
until you have reached the desired results. Lightly retighten when adjusted.
Both ends of the Upper Wire Guide will need to be adjusted evenly.
Hint: The purpose of the wire guide is to guide the sheets of the book
under the narrow loops of the wire. Some fine adjustment may be
necessary if some of the top sheets are not in the closed wire after the
book has been bound. To set this adjustment, make sure the wire is in the
loaded position with the Upper Wire Guide down, resting above the narrow
loops of the wire. At eye level to the book table, move the upper wire
guide as described above until you cannot see the narrow loops below the
upper wire guide (The Upper Wire Guide on the EWC-8370 must be down
before machine can operate). With all other adjustments set, lift up the
upper wire guide by pulling it up away from the book table to expose the
narrow loops of the wire. The narrow loops should line up with the center
of the holes in the book. Move the book stop knob to bring the holes in the
book to the correct position relative to the narrow loops of wire.
Fig. 7

983001 8370 EWC8370 8318 Issue May 2007 Page 13
STEP 8, Load Book:
Just prior to loading the book, the Rear inside Cover needs to be moved to
the front of the book. This has three benefits. First, after binding, when you
roll the rear cover back to its correct position, the rear cover hides the wire
bind in the last page of the book making a professional presentation. Second,
it allows for use of the Book Guide to compensate for overhanging covers
described later. Third, having the thicker cover sheet directly adjacent to the
bind prevents pages from falling out of a loose bind. Follow the three steps in
Figure 8a to Roll the Rear Cover and position the Book on the Machine.
Fig. 8a

983001 8370 EWC8370 8318 Issue May 2007 Page 14
STEP 8, Adjust Book Guide:
Locate the book guide adjustment knob in Figure 8b item 1 only located on
the left side of the machine. Unlock the center winged knob and turn the
outside dial until the book guide indicator is in front of the book length to be
bound. Fine tune while the Book is aligned to the Book Guide (2) and the
punched holes align with the Wire (3). See Figure 8c. If overhanging covers
are to be used (4), offset of book to cover can be obtained by loosening the
overhanging cover guide knob (5) and offsetting the contents of book to cover
with the Covers under the Overhanging Cover Guide (6). The alignment of the
Cover Holes and Book Holes (7) to the wire will have to be done manually
when using overhanging covers. Retighten when adjusted.
Hint: The book guide will have to be adjusted manually if the book is not a
standard size or if overhanging covers are used. To do this, make sure all
other adjustments are made and a wire is in its loaded position. Simply lift
up the upper wire guide away from the book table and line the holes of the
book laterally to the upper, narrow loops of the wire. Adjust book guide to
edge of book.

Fig. 8c
STEP 9, Bind: See Figure 9.
Bind (Close) the book (EWC-8370, Push buttons). Pull the Binding handle all
the way forward and down then return to the upward and back position. Lift
the Upper Wire Guide while removing the book then go to STEP 10.
Fig. 9
STEP 10, Check the Bind:
Wire varies from any two manufacturers, after you have closed your first wire,
check the quality of the close. With the EWC-8370, reverse the correction
direction, these levers move in the opposite direction.
Even Close: An Even Close is the optimal wire close. The machine
is setup and ready to begin the job. Flip the book rear cover back to
the back of the book (Notice this hides the bind).
Over Close: An Over Close can be corrected by repeating STEPs
3A and 3B and adjusting the lower closing bar towards the next
higher wire No.. Then repeat setup STEPs 4 through 10.
Under Close: An Under Close can be corrected by repeating STEPs
3A and 3B and adjusting the lower closing bar slightly rearward.
Then repeat setup STEPs 4 through 10.

5) Calendar Binding (HC-8318 only):
The HC 8318 Wire Inserter can bind books up to18” (457MM) long or documents
with a calendar hanger inserted into the two wire elements. When binding any
continuous wire up to 18” long, use the prior instructions for binding a book. All
setup instructions are the same for the 18” version except where listed below.
Books will have to be punched with a thumb cut style die that have two loops
missing where the thumb cut is placed. The pitch has to remain continuous from
the first to the last hole.
Binding a document with a calendar hanger: The calendar hanger will always
be placed in the center of the machine into the wire elements. The two wire
elements will be placed to the left and the right of the hanger.
¾There is a label on the table specifying the placement of the hanger that is
located at the centerline of the machine. On each side of the hanger label
are single book stops. Place the left element so the loop on the extreme
right side is placed on the right side of the book stop. Now place the right
elements extreme left loop over the left side of the book stop.
¾Place the hanger between both wire elements. Make sure hanger falls into
slot on table.
¾Rotate the Upper Wire Guide down. Magnets will hold the wire elements
firmly in place while inserting calendar.
¾Place the calendar into the opening with covers down. Make sure it is all
the way in against book stops and to the left against the book guide.
¾Pull the handle all the way down to close the wire.
¾Place the handle to its full open position.
¾Remove document and check close.

6) Glossary of Terms:
Fig. 11 Fig. 12
¾Element / Wire
References to the wire as a whole. I.e.: 32 loops
¾Narrow Loop
The section of the element that is closed into the holes of the book. Faces up
when loaded properly. One loop = 1 hole.
¾Wide Loop
The part of the element that is loaded facing in the down position.
¾Pitch
Measured from element to element or the number of elements in an inch.
¾Under / Over Pitch
Measured from the first loop of any given wire length to the last loop. If the
pitch is too far under, the wire will have to be stretched a slight amount over
book stop when element is loaded. Wire should be slightly under pitch. If wire
is over pitch adjust the Book Guide to center the book over the length of the
wire.
¾Shape
The shape of any given wire should resemble two half circles. If the wire looks
like one half is smaller than the other, you may have problems closing the
wire evenly (Cross-match).

¾Close
How near the narrow loop is to the wide loop when element is closed. Narrow
loop should overlap wide loop by about 1/32” when closed.
¾Cross-match
The evenness of the bind. Viewed from end.
Even Close: An even close is the most desirable type of bind.
Over Close: When the wide loops are closed under the narrow loops, the covers
may slip out of the bind if not closed tight enough.
Under Close: When the narrow loops are closed under the wide loops, the wire
forms a wedge, which will keep the covers in the wire from falling out. This is also
a desirable bind. The wire still has to be closed tight enough with the closing bar
adjustment knobs.
