      For more controller action on the thre ad,  l00sen the stop screw
(P,Fíg. 18) at the right of the controller and set the stop lower, and
for less action  set the stop higher.

      To strengthen the actian of the controller spring on the thre ad,
Toosen the  spring stud screw (0.Fig. 18) at the rear of the stop screw
and turn the spr ing stud (0,F1g. 18)  sl1ghtly  to the left with a screw
ariver,  or to l1ghten 1ts action turn to the r1ght and retighten the
spring stud SCrew.

                 To Set the Need le Bar
      See that the needles are up in the holder as far as they wil1 go.
 There are two lines across the needle bar about two Inches above the
 lwer end.  When the needle bar 1s at 1ts lOwest pos1tion, the upper
 mark  should be just visible at the end  of  the needle  bar  frame.

      In case the needle bar 1s not correctly  set, l00sen the ne ed le bar
 connecting stud pinch screws  (G,F1g.4)  and place  the needle bar in
 cor rect position as directed above, then retighten  the screws  (G).


        To Set a Needle Bar  Which Has No Mark

      Adjust the feed eccentr 1c (B,F1g. 17) so that there 1s no feed
 movement  of the  ne edle bar frame, then set the needle bar so that when
 1t rises 1/8 inch  fram 1ts lowest pos1t 1on, the points of the sewing
hooks w1ll be about  1/16 Inch above the eyes  of the needles.


       Rel ative  Positions of Vibrating Presser  Bar
                and  Lift ing Presser Bar

     The distance between  the vibrat ing presser bar and lifting presser
bar, after adjusting the feed eccentric (B,Flg. 17) so that there 1s no
 feed movement  of the needle bar, should be 5/8 Inch as shwn in F1g. 4.

      If the distance  between  the vibrating presser bar and the l1fting
presser bar  1s more  or less,  1nsert a screwdriver  In the hole at
 (C,FÍg.3) at the rear of the mach ine and lo0sen the clamp screw which
holds the needle bar rock îrame rock shaft.   While  this screw 1s l00se,
the  need le bar frame can be moved forward or backward to the required
 distance.  A píece of   me tal of the correct width may be used to deter
míne the correct  distance.   When making this adjustment be sure to see
that the feed eccentric (B,F1g. 17)  1s set so that there is no feeding
movement  of the need le bar.  When the adjustnent has been made, securely
tighten the clamp screw at C.

            To Change the Amount of Lift of
             the Alternating  Pressers
     The height of 11ft of the pressers 1s adjustable by  mov  ing the
1ink (F,F1g.4) to any of the four holes in the rock shaft crank.  The
maximum  l1ft 1s secured with the link in the bottom  hole.  The  amount
of lift should be regulated accord ing to the thickme ss of the mater1al
be ing sewn.   The  feet should  11ft  Jus t high enough  to clear the
material.

        To Adjust the   Relat ive Height of Lift
        of the Vi brat ing and Lifting Pressers
      As a rule, the vibrat ing and lifting  pres sers should  11ft an equal
 height,  but some grades of work may require that they l1ft an unequal
 he 1ght.  To change the relative l1ft of the presser feet, l00sen the
 screw  (E, Fig.3) at the back  of the machine and move  the vibrat ing
 presser bar upward or downward  as required,  then secure ly t1ghten
 the screw  (E).


               To Time the Sewing Hook
      Adjust the feed eccentr1c (B,F1g. 17) so that there 1s no  feed íng
 motion.
      Remove the thr oat plate  and turn the balance wheel over toward
 you unt1l the lower mark across the needle bar 1s Just vis1ble at the
 end of the ne edle bar frame on the upward  stroke of the needle bar.
 If the needle bar and sewing hookS are correctly t med, the points  of
  the hooks wi11 be at the centers of the needles and about 1/16 inch
  above the eyes.
      In case the sewing hooks are not correctly  timed, trn the balance
  wheel  over toward you  unt11 the needle bar has descended  to  its lawest
  point and has risen unt1l the   l  wer timing mark across the needle bar
  is Just vis1ble at theend of the needle bar frame.

       Loasen the two screws  in the hub of each hook driv ing gear (T,F1g.
   19) and tap this gear to the right or left on the hook driving shaft
    unt 1l the point  of the hook 1s at the center of the needle.  Tapping  tO
  the right gives an earller hook timing, and to the left a later hook
  timing.   Secure ly tíghten the two set screws in each gear (T).

18
   To Set the Sewing  Hooks To or From the Needles
     To prevent the points  of the hooks from div id1ng the strands                        f
the thread, they should rn as close  to the need les (within the scare)
as poss1ble.





                                                                      E2459                     R  S        U   S T  R

     Turn tke balance wheel over toward you until the   po ints of the
sewing hooks are at the centers  of the ne ed les.  Lo0sen the four screws
(R,F1g. 19) nderneath  the bed of the machine and move the hook s ad dles
tothe rlght or left, as may be requlred,  until the points  of the hooks
are as clos e to the needles as poss1ble without str1king them, then
securely tighten the four screws (R).
     The   ne edle guard  (Y,F1g. 21), which 1s attached  to the side of each
sewing hook, should be sprung unt1l 1t prevents the needle from str1king
the hook  in case the needle 1s detlected towards the hook,

    To Remove the Bobbin Cases  from the  Sewing Hooks
      Remove the bobbin  case  opene rs (M,Fig. 20); remove the four hook
 o1b screws (W,Fig. 20) irom each  sew ing hook,  l1ft off the hook gibs
 (7.Fig.21) and remove the bobbin cases (X,Fig. 20).
     To Remove  the  Sewing Hooks  from the Mach ine
      Remove the throat plate, feed dog and the bobb in case openers.
 L.o0sen  the twO Screws in each hook shaft gear (S,Fig. 19) and lift out

           To Raise or Lower the Feed  Dog
     Usually  when the feed dog is at 1ts highest pos1tion,  1t should
show a full tOoth above the throat plate.
     Remove the throat plate; clean the lint and dust from between the
feed  points and replace  the throat plate;  tip the machine  back and
trn the balance wheel towards you until the feed dog 1s at 1ts highest
position;  l00sen screw (U,F1g. 19) in the feed l1fting cam fork on the
feed bar and raise or lower  the feed dog, as may be required,  and
retighten the screw (U).
                                                                                                                                d og, be careful  that lts nder     When raising or lwering  the feed
S1de d0es not drop low enough to strike  the sewing hooks.
     The feed dog should be set so that the needles are centered  in
the needle  holes.   In case the needles do not enter the holes  in the
Teed dog  correctly, loos en the pinch screw  (H, F1g.5)  and adjust  the
feed dog as required,  then securely  tighten  the pinch  sorew  (H).

    To Remove the Need le Bar Rock Frame Rock Shaft
      Remove the face plate and needle bar  r 0ck  frame, then loosen  the
clamp screw at (C,F1g.3) and draw  out the rock shaft.
       To Remove the Arm Shaft  Connecti on Belt
                    from  wi thin the Arm
      Sl1de the connection belt off the lower belt pulley;  remove the
balance  wheel; l00sen the three sCrews in the arm shaft bush ing near
the balance  wheel and remove the bushing;  l1ft the belt up through  the
arm cap hole as far as poss1ble and draw  1t out through  the space
normally  occupled  by the bushing.
      Owing to the fact that the sewing  hooks make two revolutions to
one  revolut  i on of the hook driving shaft, and that the feed liting
eccentric  1s on the hook  driv ing shaft,  1t 1s possible to have the
sewing hooks correctly  timed without hav1ng the feed correctly  timed.
To  overcame this, the plate  (J,F1g.5)  1s attached  to the unders 1de  of
the bed of the machine.  This plate is marked with an arrow at 1ts
lower end and directly  alongs1de of the plate  is the collar (K,F1g.5)
nounted on the hook shaft, which is also marked with an arrow.  After
replacing the belt over the upper pulley, replace the arm shaft bush ing
and  securely fasten 1t In position by 1ts three screws; replace the
balance wheel.  W1th the belt on the upper pulley,  turn the balance
wheel fram you nt1l the thread take-up lever is at 1ts highest po lnt.
Then  turn the hook shaft with the fingers  unt11  the two arrOwS, one on
the plate  (J) and the other on the collar  (K), are directly in line.
NOw, without dlsturbIng e1ther the arn shaft or the hook shaft, slip
the belt over the lower pulley.  The  feed will then be correctly timed
with  the needle bar.

                        Belt Replacer  285058

21

     To facilitate  the replac ing of the belt  on the lower pulley,  use
belt replacer 285058  (A,Fig.22).  Rest the replacer  in the loop of the
the belt and sl1de  1t ver the hub of the pulley, as shown in Flg. 22,
hav ing the notches in the replacer engage the two set screws in the
hub  of the pulley.   Catch the be lt cllps in the groove at the lower
part of the pulley and turn the balance wheel toward you unt1l  t he
belt 1s fully over the pulley, assisting the belt clips from under the
pulley rim with a screwdr iver when necessary.  Then remove the replacer.
      NOTE:   As belt replacer 265058 w1ll  serve for several machines
 it 1s not regularly furnished with the  mach ine, andmust be ordered
separately.
          To Re-engage the Safety Clutch
     The hook driv ing shaft and the shafts of the sewing hooks are
splined to prevent the hooks from getting out of time.  The safety
clutch l0cated  in the lower belt pulley  prevents  damage  in the event
of any unusual  strain on the sewing hooks by releas ing the locking
lever 1n the pulley from the notch (D1,F1g. 24) 1n the collar of the
hook dr iving shaft.
