BEFORE YOU BEGIN PLEASE REVIEW:
Proper hole preparation procedures.
The KATO Linear Arm (2KLRM-1) to reduce operator fatigue and injury.
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
.
•
The KATO 2KRE series tools can also be used with the KATO KFS-20 (CT5420) brushless electric
driver. The optional hex kit (2KHEX-1K) is required. The hex kit includes a Hex Sleeve and Pin.
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 2KHE 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
2KRE Series Installation Tool includes the following parts:
1 Round Mandrel Assembly (1 threaded Mandrel, 1 Pawl, 1 Spring, 1 Pin)
1 Adjusting Sleeve Housing
1 Nylon Guard
1 Lock Nut
2 Wrenches (select sizes only)
DEPTH ADJUSTMENT AND TOOL ASSEMBLY
1. Use two wrenches (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 to be installed onto the Mandrel until the Pawl engages the drive notch.
Tangless inserts are Bi-Directional, so there is no need to orient the insert.
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 Torque Adjustment Knob 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
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 another non-residual solution will provide
lubrication and help facilitate installation.
USING ALCOHOL ON LOCKING
INSERTS WILL CAUSE THE RED DYE TO BLEED.
•
Back off the insert approximately one turn so that the notch disengages from
the Pawl, and attempt installation from this position.
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
2KPE 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.
MANUAL INSTALLATION:
If desired, a handle (2KREH-UI) can be purchased for manual Tangless installation with the 2KRE
Series tools.
INSERT REMOVAL
If necessary KATO Tangless inserts can be easily removed without damaging the workpiece or the
insert by using the KATO 2KRT Series Tangless Removal Tool. The KATO removal tool can also be
used to back up inserts that are installed too deep.
