Screws (6) .
In assembling, pull Bracket (§) as far to the front as possible and secure (Bracket (8)
has 4 oblong holes). Further, adjust position of Ring @ on Shaft (9) sothat there is
no axial play of Shaft (9) within Bracket (§) .
2. Next, remove Ring @ on front end of Shaft (|) , and pull out Hub ® from Shaft
@ together with Lever @ .
3. Next, firmly assemble Hemmer Assembly to Bed takingcare of assembly height.
4. Then, set distance "A" from left folded edgeof double folded under material to needle
drop line. This distance canbe adjusted by the position of Leg part on the right end
of Slide @ secured to Screw @ .
Further, Plunger ® is fixed to the right end of Screw @ and when Hemmer is
closed, right end of Plunger @ should positively stop at the right end of Sleeve @
where Plunger @ fits in.

5. Trial sewing must be performed until desired distance "A" is obtained and when this
hasbeenconfirmed,finally set Slide @ with 2
Washers ^ and Nuts ® .
Next, confirm that Bracket is firmly fastened on Screw clamped from both
sides with2 Washers (Q) and Nuts ® .
Also, it is desireable to position Bracket @ as far as possible to the right on Screw
7. Next, assemble Arm with Plate ® to Hub ® and provisionally tighten Screw
. See illustration.
8. Then, insert Hub ® into Shaft (9) and at the same time, fit Pin (g) on upper end of

9. Assemble Ring @ previously removed onto Shaft ® . Hub @ should rotate
freely on Shaft (9) and held in position by 2 Rings @ from both slides.
10. Also, it may be necessary to adjust Bracket @ horizontally so that Pin @ on Lever
@ fits sufficiently intothe slot.
11. Next, fix Lever @ to Hub @ with 2 Washers @ and Screws @ so that when
Hemmer is in extreme right position, there is a clearance of about 1 mm between Pin
@ and top end of slot on Bracket © .
12. Now, set position of Plate ^ to a position most adequate to the knee and firmly
tighten Screw ® .
13. Next, hook Spring (Jl) to Screw Stud @ on Support (l) and Screw Stud @ on
Lever @ . This Spring @ pulls Lever @ to the right and thru Pin @ , acts to
close the Hemmer.
14. At start and finish of hemming tubular material, Plate @ is pushed by the knee to
the right to open the Hemmer.
15. Adjust the tension of Spring @ so that Lever @ quickly returns to original posi
tion when knee is released from Plate ® . For this, screw in or out Hook on the
left end of Spring @ hooked tothe groove on Screw Stud @ .
16. Next, adjust height of Screw @ so that when Plate ® is pressed bythe knee to the
right, Pin @ does not disengage from slot on Bracket @ .
By extruding Screw ® downwards, rotating range of Hub @ becomes smaller.
Finally, set Screw ® with Washer @ and Nut @ .

3. Next, insert Connection @ from the backside into the holes of Lever @ on Shaft
(D and lower end of Lever @ on Shaft @, and insert 2 Rings @ on both ends of
Connection .
4. Then, with lower partof Lever @ on Shaft @ slanted approximately 15° to the left,
provisionally tighten Screw @ on Crank @ .
5. Next, with Hook @ on Bracket @ which is assembled tothe rear of Shaft @ point
ing tothe left and upwards, provisionally tighten Bracket @ with Screw @ ,
6. Connect Hook ® and Pedal ® with Chain @ as shown in illustration. Length of
