SI1304003E-000 = 8mm ZS feeder maintenance procedures 1

2.11.2 Install the EL box

Step 1 Install the connector interfaced with the machine by screwing (tightening torque

30Ncm) using Loctite 241. Also install the feeder board assy by screwing (tightening

torque 20Ncm).

Use a Phillips screwdriver (No.1).

Step 2 Fit the nut plate on the limit switch so that the limit switch’s protruded part is inserted

in the nut plate’s hole. Then fasten the limit switch with a screw using a 1.5 hex

wrench.

Apply Loctite 241 on the screw and tighten it to 30Ncm.

Step 3 Fit the EL box onto the feeder frame by inserting the EL box’s positioning pin into the

feeder frame’s mating hole.

Step 4 Fasten the EL box with three screws using a Phillips screwdriver (No.2).

Tighten the screws to 75Ncm.

Step 5 Connect the limit switch to the feeder board assy at its connector.

Route the limit switch harness over the mount screw of the EL box.

Step 6 Place the cable cover on the EL box. Then install the earth cable of the peel motor on

the feeder body with a screw using a Phillips screwdriver (No.1).

Tightening torque of the mount screw is 40Ncm.

Note

The cable cover must be placed on the correct position to avoid its interference with mount

holes of the feeder side cover and others.

Step 7 Connect the harnesses from the feed motor, ABS board, peel motor, operation switch

and splice sensor (optional) to the feeder board assy at respective connectors.

Step 8 Install the feeder side cover referring to “2.4 Replace the feeder side cover”, step 2.

Step 9 Install the EL box cover referring to “2.3 Replace the EL box cover”, step 2.

2.12 Replace the P/O1 roller, P4 and P5 idle gears

Note

Each of those gears can be replaced separately; they do not need to be replaced as a set.

2.12.1 Remove the P/O1 roller, P4 and P5 idle gears

Step 1 Remove the top tape box cover referring to “2.2 Replace the top tape box cover”,

step 1.

Step 2 Remove the two screws fastening the “Idle gear 2” cover using a Phillips screwdriver

(No.1) then remove the “Idle gear 2” cover from the feeder body.

Note

It is recommended to insert a precision screwdriver under the cover to remove it, as it is

difficult to remove because of the two positioning pins.

Remove the two screws fastening the P/O tooth 1 block with a hex wrench (Size 2).

Step 3 Insert a scale between the P/O lever assy gear and the feeder body. Then remove the

P/O tooth 1 block and the P/O 1 roller. (Pull them together little by little to remove from

the feeder body.)

Step 4 Remove the three screws fastening the “Idle gear 1” cover with a Phillips screwdriver

(No.1). Then remove the cover from the body.

Step 5 Remove the P4 and the P5 idle gears.

2.12.2 Install the P/O1 roller, P4 and P5 idle gears

Apply a tiny amount of NSK NSL grease at where relevant positioning pins and gears come in

contact.

Note

Do not apply grease to the gear section. If the gear is contaminated with grease, wipe the

gear clean.

Step 1 Set the Idle P4 gear to the shaft close to the EL box so that the side with more teeth

faces down.

Step 2 Set the Idle P5 gear to the upper shaft so that the side with fewer teeth faces down, and

then rotate the gears slightly in order to mesh them properly.

Step 3 Fit the “Idle gear 1” cover into the holes of the positioning pins, and fasten the cover

with three screws using a Phillips screwdriver (No.1). Tightening torque is 40Ncm.

Step 4 Insert a scale between the P/O lever assy gear and the feeder body to install the P/O

tooth 1 block and P/O 1 roller.

Note

Insert the claw of the P/O tooth 1 block into the groove of the P/O 1 roller, then set them

together little by little to the feeder body.

Fasten the P/O Tooth 1 block to the feeder body with two screws using a hex wrench (Size 2).

Tightening torque is 20Ncm.

Step 5 Remove the scale and rotate the P/O lever gear to check that the gear rotates

smoothly.

Step 6 Fit the “Idle gear 2” cover into the holes of the positioning pins, and fasten the cover

with two screws using a Phillips screwdriver (No.1). Tightening torque is 40Ncm.

Step 7 Install the top tape box cover to the feeder body referring to “2.2 Replace the top

tape box cover”, step 2.
