A SMALL COMPANY WITH BIG IDEAS

®

CUTTING LARGE MC AND FLEX

For  large  MC,  BX  and  Flex  use  the 

ROTO-FLEX RF-120 or 

RF-170.

    The 

RF-120

 cuts MC from AWG 4-4 up to 2-4 and  Flex 

from 1/2” to 3/4”.  The 

RF-170

 is our largest capacity hand tool 

and cuts MC from AWG 4-4 up to 4/0 and Flex from 1/2" to 1-1/2".

BLADE STORAGE 

All our Roto-Split and Roto-Flex models 

(except the RS-101)

 have a 

blade storage cartridge contained in the knob.  To release the cartridge 

simply pop it out with the tip of a screwdriver.  Place your spare blades 

inside (up to a maximum of six) and snap the cartridge back into the 

knob.  For best results always use genuine 

"BLUE SAPPHIRE"

 Cat. 

B-102

 or 

B-107

 blades. 

BLADE LUBRICATION

Use  our  

Lubricant Stick LS-105 

for longer blade life and to prevent 

blade clogging 

(not for use on aluminum)

.   Lubricant sticks are available 

from your local distributor.  

NOTE:

 our armored cable cutters have an 

opening in front to apply the lubricant stick, simply rotate the handle 

with the 

LS-105

 inserted into the tool.

STEP 4 - REMOVING THE ARMORED CASING

With our 

"BLUE SAPPHIRE" 

blade 2 to 5 brisk turns of the handle 

should be sufficient to split the BX casing.  Hold the cable on each 

side of the cut and twist the armored casing counter-clockwise until 

it separates.  If this last step fails, you have not cut all the way 

through the armor.  Repeat the steps above.

WARNING!!

Never attempt to cut already installed BX, MC or Flex cables on 

live lines, since any contact between a live wire and ground can be lethal.

CUTTING REDUCED SIZE MC CABLE

Use the 

Roto-Split RS-101AC

 to cut  reduced diameter MC cable 

such as Southwire 

MC

AP

 Since this cable requires a reduced depth 

of cut slide the 

lever

 

f

 towards the front of the tool.  Make sure 

button 

g

 is pushed in completely 

(

flush with outer channel

)

 

to center the cable on the blade.

  Cut the cable armor as detailed 

in Step 

c

.   To cut standard MC return 

lever

 

f

 to the rear position.

Warning:  When cutting reduced wall MC the lever must 

be set forward to prevent possible damage to conductors

STEP 5 - DEPTH OF CUT ADJUSTMENT

If the Roto-Split does not completely cut through the armor it may 

be required to 

adjust the depth of cut

.  Turn the set screw in 

the top housing 

counter-clockwise a 1/4 turn 

(

use a 3/32 Allen 

wrench

).  Make a trial cut and adjust the set screw until the cas-

ing separates.  

It is critical to check that the blade does not 

nick a wire after adjusting the depth of cut.  Make a trial cut 

to test.  

Casing can be separated by inserting the tip of a screw-

driver blade into the slot and twisting to crack it open, or simply 

bend the cable slightly at the cut to snap the armored casing.

FOR LEFT HANDED USERS:

 

No problem!

  Hold  the Roto-Split upside 

down in your right hand & turn the crank clockwise with your left.
