ENGLISH
The Klein 53725 has an exclusive auto-clamping feature and strips
reduced diameter cable. Cuts armored cable up to 3/8" diameter: BX,
AC, MC, MCAP
and Greenfield. MCAP
is a registered trademark of
®
®
Southwire Company.
STEP 1 – ASSEMBLY (SEE FIG.1 oN BACK PAGE)
1. Using a small screwdriver, remove storage cartridge (A) from
drive knob (B).
2. Remove cutter blade (C) from the storage cartridge. Replace
cartridge after blade is removed.
3. Remove small thumbscrew (D) on cutter body to fully open two
cutter body halves.
4. Remove nut (E) from end of drive axle (F) opposite the handle.
5. Insert drive axle and handle assembly into cutter body (G).
6. Place blade onto drive axle with Klein Tools logo facing outwards
(H), ensuring blade is fully seated on hex portion of axle.
7. Secure the blade onto the shaft by re-installing the nut.
8. Reinstall thumbscrew while squeezing cutter body halves together.
STEP 2 - CABLE CLAMPING (SEE FIG. 2 oN BACK PAGE)
Insert cable (1) into channel and squeeze auto-clamping lever (2)
until clamping stud (4) reaches bottom of cable groove. Hold tool
near cutting head and squeeze until blade makes contact with cable.
Note: For small diameter MC, cable lever (6) must be in forward
position and button (7) must be pushed in completely (flush with
outer channel) to properly position cable.
STEP 3 - CUTTING MC CABLES
After MC cable has been clamped, hold tool near the cutting head
and squeeze. Do not apply too much pressure while pushing blade
against the cable. Rotate the crank handle (3) smoothly in clockwise
direction and adjust pressure to get most efficient cutting action.
When the force required to turn crank suddenly decreases, you have
cut all the way through. Release pressure and turn crank slightly to
return top to original position.
CUTTING rEDUCED SIZE MC CABLE
The 53725 cuts reduced diameter MC cable such as Southwire
MCAP
. Since this cable requires a reduced depth of cut, slide
®
lever (6) towards front of tool. Make sure button (7) is pushed in
completely (flush with outer channel) to center cable on blade. Cut
cable armor as detailed in Step 3. To cut standard MC, return lever
(6) to rear position.
STEP 4 - rEMoVING ArMor
Two (2) to five (5) brisk turns of the handle should be sufficient to
split BX casing. Hold cable on each side of the cut and twist armored
casing counter-clockwise until it separates. If this last step fails, you
have not cut all the way through the armor. Repeat steps above.
STEP 5 - SET DEPTH oF CUT
If the 53725 does not completely cut through the armor, you may
need to adjust depth of cut. Use a 3/32 hex wrench to turn set screw
in the top housing counter-clockwise a 1/4 turn. Make trial cut and
adjust set screw until casing separates. It is critical that the blade
does not nick a wire after adjusting depth of cut. Make trial cut to
test. Casing can be separated by inserting screwdriver blade into slot
and twisting to crack open or by bending cable slightly at cut.
BLADE LUBrICATIoN
Lubricate blade each time it is replaced to extend blade life and
prevent clogging.
BLADE STorAGE AND rEPLACEMENT
The 53725 contains a blade storage cartridge in the knob (B) which
holds up to six replacement blades. To release cartridge, pop out with
screwdriver. To replace blade, remove thumbscrew (D) on outside
of cutter body near blade. Remove nut on blade side of drive axle
(F). Remove old blade. Place new blade onto drive axle (F) with Klein
Tools logo facing outwards (H), ensuring blade is fully seated on hex
portion of axle.
