6.3 When pressing a 710 bridge module onto a 710

splice or half-tap module, insert the module

combination between the jaws of the 3M 710-BSP

Presser, cap first, with the 710 splice or half-tap

module flush against the lower jaw of the tool. Insert

the module combination until the cap rests firmly

against the back wall of the lower jaw.

1378-8125-3042-2-E

6.4 Crimp the module combination together by

squeezing the handles of the 710 bridge module

to 3M 710-BSP Splice Presser together until the

factory-set torque handle “clicks,” indicating a

complete crimp. This must be done three times, first

in the center of the module combination, and then

sequentially once on each end.

Note: If you don’t hear or feel the factory set torque

handle click while squeezing the handles, the

crimp may not be complete. Reduce the height of

the presser jaws by turning the height adjustment

nut and repeat the crimping sequence.

6.5 Check visually to confirm complete pressing of the

bridge module onto the splice or half-tap module. If

necessary, complete the assembly using additional

crimps.

7.0 Bottomless Splicing with 3M™710 25-pair Modules using the Gray

Bottomless Splice Module Support

7.1 Place a gray bottomless splice module support

into the splicing rig. The large gaps go to the side

opposite the color code guide. Push in the “L” clip

knob to secure the bottomless module support.

7.2 Place a straight or straight/half-tap module body into

the bottomless support. The module latches fit into

the cuts and face the color code guide.

14 78-8125-3042-2-E

7.3 Wrap the group to be spliced with the conductor

group holder. Dress the pairs over the colored peaks

with the conductor ends exiting towards the color

code guide. Do not pull the conductors tight to the

back of the connector. Use the error tester tool to

check for correct conductor placement.

7.4 Spread the conductors around the “T” bar without

disturbing them in the module body. Pull the “T” bar

up above the module body. Push the “T” bar forward

and down until contact is made with the conductors.

Pull the handle down to the stop, seating and cutting

the excess conductors in the module body. Remove

the excess conductors. Engage the handle into the

retaining clip, pull the “T” bar up, and place into the

open position.

7.5 Place a cap on the module body. Use finger pressure

to push down the cap to pre-engage it to the module

body. The cap latches should face the color code

guide. Pull the “T” bar up above the cap. Push the

“T” bar forward and down until contact is made with

the cap. Pull the handle down to the stop, seating the

cap into the module body. Engage the handle into the

retaining clip, pull the “T” bar up, and place into the

open position.

7.6 Remove the bottomless module from the splicing rig.

The 25-pair bottomless module is complete.

8.0 3M™710 Splicing Rig Blade Assembly Replacement

 CAUTION: Use extreme care when handling old or new blades as even used blades are very sharp.

8.1 With the “T” bar in the up position, use the 3mm hex

wrench to remove the four (4) screws on the handle

side of the splicing rig head.

8.2 Open the “T” bar and use the 3mm hex wrench to

loosen (but do not remove) the two (2) screws on the

faceplate of the splicing rig head.

8.3 Using the middle fingers of both hands, push and

hold the blade guard down. Keeping fingers away

from the blade tips, slide the blade assembly forward

by using thumbs to push metal ends of the blade

assembly forward.

8.4 Place the new cutter blade into the pocket of the

metal blade holder tool so the flat sides of the

individual blades are flush with the surface of the

metal blade holder tool.

16 78-8125-3042-2-E

8.5 Hold back the blade guard and use finger pressure

on the metal ends of the new blade assembly to

insert it behind the stuffer teeth into the blade slot of

the “T” bar.*

*Note: For proper operation you must ensure the blade

guard moves freely on both sides of the blade

assembly.

8.6 Looking at the center of the “T” bar faceplate, align

the tips of the red stuffer with the mid-point of the

individual blade tips of the cutter blade. Use the

3mm hex wrench to lightly-tighten the two (2)

screws on the faceplate.

1778-8125-3042-2-E

8.7 Install an index strip into the splicing rig and pull

the “T” bar to the upright position. Use the 3mm

hex wrench to insert and lightly-tighten the four (4)

screws on the handle side of the “T” bar to secure

the blade assembly and stuffer.

8.8 Pull the handle down to stop and up to release three

(3) times to seat the blade assembly and stuffer.

While the “T” bar is in the fully engaged down

position, use the 3mm hex wrench to securely

tighten all six (6) screws.

8.9 Engage the handle into the retaining clip, pull

the “T” bar up, and place into the open position.

Examine the index strip. Slight knife cuts of uniform

depth should be visible on the cutting ledge, but

not contacting the cathedral windows. If cut is not

positioned correctly repeat steps 8.1–8.9.
