The machine head. frame and
motor
etc.are packed separately. First assemble
the
frame,thcn set
the
motor
at
the
long hole
of
the
frame beam, and fix it with screw.
Then
place
the
table
and
machine head
and align their positions. Thighten all screws and nuts.
2.Cleaning grease dirt.
The
machine are coated with anti-rust grease
to
p~vint
if
from rusiting before packing. But it may be
through long time storage and long
way
transport, the grease may become hardened
or
dust may
accumulate
On
it ,
The
grease on
the
surface
of
the
machine
must
be cleaned with gasoline and clean soft
clothafter unpacking.
3.Checkingthe
machine
The
machine may
get
strong shaking
in
the
transport leading
to
loosening
or
shifting
of
its parts.
Check
the machine completely after cleaning it ,
Tum
the belt pulley
of
the
main shaft with hand and
observe wheather the feeding wheel and the grinding wheel impact
the
edge
of
the.circular knife
or
not,
If
there is any impact,adjust
the
machine according
to
the
methods
of
this instruction book, make
the
feeding
wheel and
the
grinding wheel keep a clearance with
the
edge
ofthe
knife.
4.Filling oil and testing.
Before starting
the
machine, fill oil
at
oil holes and moving parts.
Let
the
machine run a few minutes
for testing,
The
belt pulley
of
the
main
shaft sttould fum clockwise.(observe from
the
t?ght
of
operator)
IV
.How to use and adjust the machine.
l.To adjust the position
of
the circular knife.
13
From the library of: Superior Sewing Machine & Supply LLC
The edge
of
the knife should keep a clearance about 0.4-0.Smm with the side
of
presser foot(figure
l)
This clearance is an important factor for assuring skiving quality, The edge
of
the knife will get dull
through skiving, and need to regring. After several times or long time regrinding the relative position
of
the edge
of
the knife to the feeding grinding wheel and the side
of
presser foot will change, and can
be
m.ade
up by means
of
adjusting the axial position
of
the knife.
JS-801:The circular knife adjustment consists
of
precise worm and worm wheel whick can make
micro-adjusting by means
of
tui:t_ting
the adjusting handle
of
the knife. Turn clockwise to increase the
clearance and tum it counterclockwise
··o
decrease the clearance.(see Figure 2)
2.To regrind the circular knjfe
The grinding wheel
of
the knife rotales when the machine works normally, so the edge
of
the knife
can
be
regrund continually. Also can regrind it afterthe edge
of
the knife get dull. When
tum
the adjusting
screw bar
of
the grinding wheel counter-clock wise, the grinding wheel closes to the dege
of
the knife and
does grinding;turn the adjusting screw bar
_clackwise,
the grinding wheel leaves
t.t'l.e
edge
of
the knife and
stop grinding.(see Figure
3)
Caution: When grinding the
edge
of
theknife, the grinding wheel should advance slowly
to
prevent
the grinding wheel from impacting the edge
of
the knife, leading to destorythe grinding wheel orthe edge,
even work accidents,
3.
To
adjust the beight and centre
of
the
feedi~g
wheel arc.
The feeding wheel has two functions, The main one is feeding material, anotheris grinding burrs
of
the inner side
of
the knife. The R centre
of
the feeding wheel should be identical with the R centre
of
the
knife. Tills will do quite well
to
feedi'.lg the material
md
grinding the knife.The R centres should be
adjusted
if
they are not on the same axis.
The
method
is;
loosen the R adjusting nut
of
feeding wheel,
turn
the R adjusting screw bar
of
feeding wheel when the clearance
is
big between the inner diameter
of
the
knife and the right side
of
feeding wheel, tum the adjusting screw bar clockwise,
on
the cluntrary side,
turn the adjusting screw bar counterclockwise until the clearance is consistent between the feeding wheel
Rand
both sides
of
the inner diameter
of
the knife.Then retighten the adjusting nut
R.
The outer diameter
of
the feeding wheel should connect the inner diameter
of
the knife. The big
clearance between them will cause unsmooth feeding and poor quality skiving. The over interference will
destroythe knife, The height
of
the feedif!g wheel
is
adjusted by means
of
loosening the adjusting nut, and
turning the adjusting screw bar, tum clock wise to increase the height, turn counterclockwise
to
decrease
the height, and tighten the height adjusting nut to adjust their connect.(Figure 3)
4.
To
adjust the height
and
angle
of
the presser foot.
(a).
To
adjust the height
of
the presser foot.
To
do heavy leather skiving or
srr.n!J
volume skiving, ii is to incerease the height
of
the presser
foot.And to do light leather skiving or big volume skiving, it is to decrease the height
of
the presser foot.
The height
of
the presser foot
is
adjusted by means
of
adjusting the presser foot height adjusting screw bar.
Tum it clock wise to decrease the height, tum it counterclockwise to increase the height.
(B).
To
adjustthe angle
of
the presser foot.

To
do big width and smail angel edge-skiving, the
angl<!
between the presser- foot and the circular
knife should
be
small. On the contrary, the angle should be big. The height
of
the angle is adjusted by
means
of
loosening the angle adjusting nut
of
the presser. foot and turning the angle adjusting screw bar
Tum
it clockwise to increase the angle, and turn it counterclock wise to decrease the angei.After the
required angle is adjusted, retighten the adjusting nut.(see Figure 4)

To
adjust skiving speed.
The leather skiing machine with the circlar knife has three speeds to choose depending
on
operator
skill and the skiving matitial. To adjust the speed,
:frrst
open andtake a way belt cover, slide
the
beot into
required skiving spped with screw driver, right side is lowspeed and left is high speed.(see Figure 6)

.To
dress the grinding wheel.
1.
To dress the feeding grinding wh'!el.
After long time use, various kinds
of
skiving chips are stuck on the surface
of
the feeding
wheel.weaken feeding friction force, lead to unsmooth feeding. Toresume normal feeding, the surface
of
the feeding wheel must be dressed with grinding wheel dresser. First remove the feeding sliding plate to
let the feeding wheel lie bare.switch on the machine, aim the dresser
at
the feeding wheel. The teeth
of
the
dresser rotate with the feeding wheel and move left
and
right until
the
surface
of
the feeding whell become
sharp.(see Figure 7)
2.To dress the grinding wheel.
After regrinding the edge
of
the knife several times, grinding chips
of
metal and the grinding wheel
are stuck on its surface, weaken grinding speed and quality. So its surface must
be
dressed with tile
grinding wheel dresser.(seeFigure 8)
