BEFORE YOU BEGIN PLEASE REVIEW
Proper hole preparation procedures.
The KATO Linear Arm (2KLRM-1) to reduce operator fatigue and injury.
TIPS & TRICKS
Having difficulty getting the insert started? Try one or more of these helpful tips:
Tap the Trigger on the Electric Driver in Short intervals until the insert begins
to enter the tapped hole
Dipping the insert in Alcohol or other non-residual solution will provide
lubrication and may help facilitate installation. USING ALCOHOL ON LOCKING
INSERTS WILL CAUSE THE RED DYE TO BLEED.
IMPORTANT NOTES
• A step by step instructional video can be found in the KATOpedia section of the KATO website
www.katofastening.com.
• The Installation Mandrel (see figure 1) is designed to be used with the KATO SB-400C Electric
Driver (CT5405) for sizes 2-56 thru 6-32, and M2.5 thru M4; or the KATO SB-650C Electric Driver
(CT5406) for sizes 6-32 thru 3/8”, and M5 thru M8.
Please note that the Power Transformer SBT-50 is no longer available from the manufacturer;
therefore, KATO is no longer offering the Power Transformer, the SB-400C and the SB-650C.
KATO recommends using the CT5420 driver with the KHE series installation mandrel.
REQUIRED COMPONENTS
The KATO Non-Prewinder Electric Installation System consists of:
•SBT-50 Power Transformer (CT5407)
•SB-400C Electric Diver (CT5405), and/or SB-650C Electric Diver (CT5406)
COMPONENTS LIST
The KRE Series Installation Tool includes the following parts:
1 Round Mandrel
1 Adjusting Sleeve Housing
1 Nylon Guard (already assembled on housing)
1 Lock Nut
DEPTH ADJUSTMENT AND TOOL ASSEMBLY
1. Use two wrenches (not provided) to loosen the Lock Nut and Adjusting Sleeve on the Mandrel.
2. Thread the Lock Nut and Adjusting Sleeve towards the back of the Mandrel to fully expose the
front threads.
3. Thread the insert onto the Mandrel until the Drive Contour engages the tang.
4. Turn the Adjusting Sleeve until the Nylon Guard is approximately 1 thread behind the end of the
insert. This will ensure proper installation depth (3/4 - 1 1/2 threads below the surface for a hole
with a countersink; 1/4 - 1/2 threads below the surface for a hole without a countersink).
Note: Inserts may vary ± 0.25 coil. KATO recommends that the installation depth of each lot be
tested using a sample tapped hole prior to installing the inserts into the production part.
5. Use the two wrenches to lightly tighten the Lock Nut against the Adjusting Sleeve. (Be careful not
to move the Adjusting Sleeve when tightening)
6. Install the Mandrel into the Standard Chuck and tighten using the provided chuck key.
TORQUE ADJUSTMENT & INSERT INSTALLATION
BULK INSERTS:
7. Always use the minimum amount of torque that will install the insert. This will minimize the
possibility of breaking the Mandrel or Pawl and increase the life of the tool. Start with a very low
torque setting on the electric driver. Tighten the Knurled Nut to increase torque and loosen to
decrease torque.
8. Hold the electric tool perpendicular to the tapped hole and align the insert. Straight alignment will
provide smooth installation and longer tool life.
9. Actuate the driver by pressing the Trigger.
10. Continue to hold down the Trigger as the Installation Mandrel threads the insert into the tapped
hole.
11. Once the insert is fully installed, the Electric tool will automatically reverse. Be sure to hold the
Trigger down until the Mandrel fully retracts from the installed insert. If you release the Trigger
prematurely the Electric Driver will reset. When the Trigger is depressed again the Driver will run
forward. Hold the Trigger until the Mandrel exits the tapped hole.
Note: The insert can be loaded onto the mandrel manually, or you can hold the insert in one hand
and tap the Trigger on the Electric Driver with the other hand.
STRIP-FEED INSERTS:
KATO does not recommend using strip-feed inserts with non-prewinder electric tools. The KATO KPE
Series Electric Tool Front End Assembly is strongly recommended when using strip-feed inserts.
DO NOT APPLY ANY DOWNWARD PRESSURE OR TRY TO FORCE THE INSERT INTO THE
HOLE, LET THE WEIGHT OF THE TOOL DO THE WORK. FORCING THE INSERT INTO THE
TAPPED HOLE MAY RESULT IN INSTALLATION FAILURE AND CAUSE DAMAGE TO THE
TOOL AND/OR WORKPIECE.
TANG REMOVAL
In accordance with NASM33537 Section 13.3 “The Tang should be removed from the insert after
installation.” For easy Tang removal use the KATO Tang Break-Off Tool (KTBT Series).
