OPERATING INSTRUCTIONS

NOTE: 

Use only on wood frames / structures of low or medium density. Hard woods may cause 

malfunction or partial staple penetration. Always ensure proper staple size is loaded in cable stapler.

STAPLE SELECTION (FIG. 1, FIG. 2):

WORKS EXCLUSIVELY WITH KLEIN TOOLS STAPLES. NOT COMPATIBLE WITH OTHER BRANDS OF STAPLES.

Determine appropriate staple size for cable type (see staple size guide on side of stapler):

• 450-001

 - 1/4" for: CAT3, CAT5e, or speaker wire

• 450-002

 - 5/16" for: CAT3, CAT5e, or CAT6/6A, Coax

• 450-003

 - 19/32" for: NM: 14/3, 14/3G, 12/3, Qty 1 or 2 Coax, or Qty 1 to 3 CAT3/5e/6/6A 

• 450-004

 - 31/64" for: NM: 14/2, 14/2G, 10/2, 10/2G, or Qty 1 or 2 speaker wires

For use with 450-001 or 450-002:

 Ensure the Staple / Cable Size Selector 

6

 is in the down position 

(FIG. 1). If it is in the up position, grasp staple guide firmly and pull down until locked. The Staple / 

Cable Size Selector 

6

 is locked in the down position when the Locking Buttons 

8

 are fully released.

For use with 450-003 or 450-004:

 Ensure the Staple / Cable Size Selector 

6

 is in the up position (FIG. 

2). If it is in the down position, depress both Locking Buttons 

8

 (on both sides of stapler), and slide the 

Staple / Cable Size Selector 

6

 to the up position. Ensure that the cable opening is fully exposed.

STAPLE TENSION ADJUSTMENT:

For use with 450-001 and 450-002:

 Tension Setting Lever 

2

 should be in the lower tension, down position. 

For use with 450-003 and 450-004:

 Tension Setting lever 

2

 should be in the higher tension, up position. 

To change between positions, push in and turn gently. For reference, the higher tension setting may 

be necessary when using the 450-001 and 450-002 with harder woods, and the lower tension may be 

necessary when using 450-003 and 450-004 on softer materials, such as drywall. Perform a test setting 

determination on a non-visible surface.

LOADING STAPLES:

1. Hold staple gun upside down, depress Push Rod Release Latch 

4

, pull out Staple Push Rod 

3

.

2. Insert appropriate staple, with the legs pointing up (FIG. 3). 
3. Firmly push the Push Rod Release Latch 

4

 closed. 

NOTE:

 DO NOT mix staples of different sizes. Partial strips, damaged strips or mixing of different sized 

staples may jam the stapler.

STAPLING CABLE:

1. Locate stapler over cable, ensuring cable is contained within the Cable Guides 

9

 for entire length of 

stapler, front to back.

2. Press Handle 

1

 firmly downward to release staple. 

3. If staples jam, ensure that you are using the proper staple size and tension setting. Also ensure that 

you are not attempting to staple into a surface that cannot be penetrated by a staple. In the event of a 

jam, clear jammed staple gently, wearing gloves to prevent injury to hands.

 WARNINGS

Read all instructions thoroughly prior to use.  Failure to read, understand, and follow all instructions 

may result in serious injury. 

• 

Never work on or near live electric circuits. 

• 

Always wear approved eye protection and hearing protection.

• 

Keep fingers clear of staple discharge area when operating or clearing a jam.

• 

Only direct staple discharge towards surface intended to be stapled; never point towards any body part.

• 

Ensure correct staple size is selected before discharging.

• 

Use proper positioning of the cable guide to prevent staples from piercing the cable

• 

Always be cautious of potential hazards such as electrical wiring, damp or wet conditions, unstable surfaces.

• 

For professional use only.

• 

Keep away from children.

The Klein Tools Cable Stapler features a forward action for greater stability.  It is designed to allow user to 

push the handle, rather than squeeze, delivering easy, consistent performance.  The staples are released 

from the front end of stapler, nearest to where the handle is pressed down. A cable guide along the entire 

bottom surface protects the cable from being crushed during the stapling process.
