Bostitch: Operation and Maintenance Manual
FOREWORD
This instruction book and parts catalog is provided for operators of single stitch
wire stitching machines equipped with the following models of BOSTITCH Bliss
Wire Stitcher Heads:
In preparing this manual, the aim has been to give the essential details covering
the operation and maintenance of the Stitcher Head, and to provide a complete
breakdown of component parts of the head for the purpose of ordering repair parts.
The first section of Part I gives a general description of the BOSTITCH Bliss
Stitcher Heads, and includes a table listing the full range of wire types and sizes
handled by the heads.
The second section, Operating Adjustments, gives detailed instructions, with ac-
companying illustrations, for making the various required adjustments for the proper
operation of the heads. These instructions include simple formulas for calculating
the wire draw (length of wire to be fed) for any thickness of work within the stitch-
ing capacity of the heads.
The third section of Part I, Maintenance, gives detailed instructions, with accom-
panying illustrations, covering procedures for properly maintaining the head. A
Trouble Shooting Chart, which illustrates perfect and imperfect stitches, and lists
the causes of imperfect stitching with instructions for remedying the imperfections,
is also included in this section.
In order to expedite the ordering of repair parts, fully illustrated parts lists cover-
ing component parts of the above listed models of BOSTITCH Bliss Stitcher Heads
are provided in Part II of this book. Instructions on how to order a part, as well as
complete instructions for disassembling and reassembling the head, are included in
this section. In addition, a Numerical Index (all parts numbers listed in numerical
order and cross referenced to the Parts List and illustrations) is provided at the back
of the book.

OPERATING ADJUSTMENTS
The quality and quantity of work that can be pro-
duced by a BOSTITCH Bliss Stitcher Head is depen-
dent upon the operator making the various operating
adjustments as accurately as possible. The following
illustrated instructions are provided so that the oper-
ator wiH clearly understand how to make the various
required adjustments.

6. HOW TO ALIGN GRIPPER BAR AND FORMERS
(See Fig. 13)
a. Turn over the machine manually and, as the
formers (1) descend, check that the grooves in the
formers are in exact alignment with the wire length
being held by the gripper bar (2).
.b If they are not in alignment, (usually resulting in
deformed crown surface), loosen the clamp block
holding screw (3). Then turn gripper bar adjusting
screw (4) in or out, as required, until alignment is cor-
rect. After adjustment has been made, tighten clamp
block holding screw (3).
CAUTION
After replacing the above mentioned parts, or
after installing a new part, turn over machine
manually and check that head operates freely.
Do not operate machine under power until certain
that head is operating freely
1. LUBRICATION (See Fig. 16)
Use an S.A.E. No. 10 oil for lubricating the
BOSTITCH Bliss Stitcher Head. Machines that are in
constant operation should be lubricated daily; machines
that are operated periodically should be lubricated just
prior to running a job. Figure 14—Wire Fed Gear Tension
Usually only a drop of oil is required at each point Adjustment
of lubrication.
Depending upon the type of work being stitched,
care must be taken that those parts of the head that
contact the work are free of oil. Lubricate regularly
instead of excessively. After lubricating the head, wipe
off any excess oil.
In addition to the above lubricating points, apply a few drops of oil as required to wire oiler
fel't (not shown in illustration) to clean and lubricate stitching wire. Friction points of all sliding,
rotating or oscillating parts, for which oil cups or holes are not provided, should be oil moisteried
just prior to running a job. It is recommended that a tooth pick, or matchstick, tipped with oil
moistened cotton dressing be used to lubricate these parts.

(Continued on page 12) .
2—Manually holding cutter plunger (4 )under spring
tension, back-out cutter plunger holding screw (5)
sufficiently to release plunger (4 ) and cutter (6) from
cutter block.
3—To replace cutter into cutter block, first loosen
stationary cutter holding screws (7) and back-out sta-
tionary cutter (8 ) slightly.
4—Fit top of movable cutter (6) into groove in
plunger (4), with flat cutting surface of cutter turned
toward plunger. Slide cutter and plunger into their
holes in cutter block, and then compress plunger by
hand until top of plunger is just below the top of cutter
block body; then, tighten plunger holding screw (5)
until it engages slot in side of plunger, thereby holding
plunger in place. (If plunger holding screw (5 ) pro-
trudes from its hole in cutter block body, it is not cor-
rectly engaged with slot in plunger.)
5—Slide stationary cutter (8 ) back into cutter block
body until its cutting end surface contacts and is paral-
lel with cutting surface of movable cutter. (Upon
contact with stationary cutter, movable cutter will
automatically align itself with stationary cutter.) When
cutters are correctly aligned, tighten stationary cutter
holding screws (7).
6—Reinstall cutter block (2) onto its holding plate
( 3 ) . On all heads other than Models BHOL and
BHL485 be sure to position cutter block so that the
cutter block adjusting screw head (9) engages in the Figure 17—Inspecting Wire Feed Gears, Tubes,

(Models BHOL and BHL485 are not equipped with
this control slide ). With cutter block correctly posi-
tioned, replace and tighten cutter block holding screw
(1).
7—Turn over machine by hand and check that mov-
able cutter operates freely; check that cutter stroke is
correct. If cutter has been resharpened, or a new cutter
has been installed, cutter stroke may need resetting.
(Refer to para. 5, pg. 8)
e. GRIPPER (See Fig. 19)—Check for excessive
wear at edges of gripper bar (1) anvil (surface upon
which staples are formed), usually evidenced by
rounded corners on formed staple.
Check for signs of wear on gripping surface of grip-
per bar clamp piece (see Index No. 152 in Fig. 23);
check for sufficient tension in gripper bar clamp piece
spring. If clamp piece is overly worn, or spring tension
is not sufficient, wire will slip while being held in the
gripper usually resulting in a one-legged staple.

After the arc'd wire forming parts have been installed
and all standard adjustments have been made, turn
drive pulley by hand to make sure all parts move freely.
Thread wire between Wire Feed Gears. Turn throwout
handle to close gears. Then operate the machine until
wire passes through the cutter block and is being cut
off. Check the wire to see that there is the right amount
of arc. Wire should have an arc of .026 to .029 (.66mm
to .74mm).
If there is not enough arc in the-wire, increase the
wire feed pressure by turning the wire feed pressure
adjusting screw clockwise one or two turns. The stitcher
is now coverted for arc'd wire stitching.
TROUBLE SHOOTING
The quality and quantity of work that can be pro-
duced with BOSTITCH Bliss Wire Stitcher Heads are
dependent upon the operator making all adjustments
as accurately as possible, and carefully maintaining the
heads. The cause of staple imperfections usually can be
traced to inaccurate settings or adjustments, or normal
wear of parts. In the event of trouble of this nature
occuring, the operator can, by referring to the following
Trouble Shooting Chart, quickly locate and remedy the
cause, or causes, of the trouble, thereby reducing to a
minimum the time the Stitcher is non-operative.
The first column of the chart illustrates perfect and
imperfect stitches; the second column describes the
imperfections (troubles); the third column lists the pro-
bable cause, or causes, for the given trouble, while the
fourth column lists the remedy, or remedies, for the
troubles. Reference is also made in the fourth column
to the paragraph in this book in which will be found
detailed information for making the necessary remedial
adjustments. Figure 20—Removing and Assembling
