1. Fix the intermediate presser variable shaft
2 setscrews so that the length of the shaft section becomes 229.5mm.
(Both setscrews
2. Insert the washer

3. Pressing the intermediate presser variable arm
pressing the thrust collar
first screw first so that it is fixed level to the intermediate presser variable shaft
screw. To be done in the same manner hereafter.)
(Caution) If there is rattle in the variable shaft of the intermediate presser
ward directions, this can be a cause of intermediate presser step-out. Be careful when you try
to fix the thrust collar
4. Adjust the distance to 4.4mm between the thrust collar

5. When the intermediate presser motor
tentatively fix it to the frame with 2 setscrews
presser motor asm. to the position where the amount of backlash becomes zero. Since then, tighten 2
setscrews .
6. Insert the sensor slit
intermediate presser lifting shaft
ring on the intermediate presser lifting shaft
7. Pressing the intermediate presser lifting shaft
the direction of the Arrow G and tighten the two setscrews
8. Fix the intermediate presser lifting cam
0.5mm between both end planes of the intermediate presser lifting cam
lifting link .
9. Turn the intermediate presser variable shaft
trailing bevel gear
means of the 2 setscrews
order to reduce the backlash to zero).
10. Press the sensor slit
section toward the setscrew
tentatively.
11. According to adjustments of intermediate presser variable as described in 3-(11), make adjustments of
intermediate presser variable and fasten the setscrews of the drive bevel gear
