The rst step in the
Tog-L-Loc® process
involves clamping of
the material with a
punch side stripper.
TOG-L-LOC®PROCESS
Next, the punch draws
the material into the
die.
As the material ows
into the die, the
die blades expand,
allowing the metal
to ow into a strong
circular interlock.
BTM’s patented Tog-L-Loc®sheet metal joining
system is the simple solution for fastening
plain or coated sheet metals. Tog-L-Loc® forms
a strong, leakproof joint without welding or
riveting in almost any combination of ductile
sheet metals. The Tog-L-Loc®system is widely
used in the manufacture of automobiles,
appliances, furniture, electrical products,
building supplies, and more.

®
Lance-N-Loc®is a sheet metal clinching
system which creates a strong mechanical
joint without the use of external fasteners or
welding. The metals are lanced and squeezed
to form an interlock below the bottom layer of
the sheet metal.
Lance-N-Loc® is good for joining harder
materials, multiple layers, and is ideal for use
where electrical conductivity is required.
The final result is a joint with a greater width
than the drawn section of the metals. This
accounts for the high strength of Lance-N-
Loc® joints. The entire sequence takes place
in a single press stroke.

SAFETY

3.0 START UP PROCEDURE
Hang the Booster as shown.
Gun should operate lower
than booster.
Start-up continues on the next page.
Read all safety instructions before operating the unit!
1. After removing your Tog-L-Loc/Lance-N-Loc system from its shipping box, make sure that you have
received two sets of Tog-L-Loc, or Lance-N-Loc, tooling. One set is already installed in the gun. The
second set should be in a package attached to the gun. Remove the second set of tooling and store
it aside.
2. Visually inspect the system for damage due to shipping. If damage has occurred, call BTM
immediately.
3. Check hoses, yoke, and the compression mechanism regularly for damage or cracks. Discontinue
use if such conditions exist.
4. Remove the booster unit from the box and hang it from the hole in the handle. Make sure the
booster unit is securely hung and will not fall or injure someone. The booster should be higher than
the gun during operation.
Hang the Booster as shown. Gun should operate lower than booster.

6. Connect your air line to the booster. BTM recommends that the system operates at 80 PSI (5.5 Bar).
Clean, dry air should be used. The removal of air supply is required before tool change or service.
7. Press the trigger on the gun and dry cycle the unit. If the unit fails to cycle, air needs to be bled
from the system. See section 4 on bleeding the gun.
Unit requirements:
Recommended Air Pressure: 80 PSI (5.5 Bar)
BTM recommends that clean, dry air is used.
Maximum Air Pressure: 90 PSI (6.2 Bar)
Recommended Oil: Amoco AW 32 to DTE 26 or any equivalent, non-foaming oil.
Oil should be handled and disposed of properly.

4.0 BLEEDING THE GUN
1. Apply air pressure to the booster by squeezing the trigger. Do this between 5 and 10 times.
2. Press and hold the trigger
(Note: Do not release the trigger until the plug is tightened - See item 3).
3. CAUTION! The unit is under hydraulic pressure. Using a 5mm allen wrench, carefully turn the plug,
located at the center of the press unit’s endcap, counterclockwise by a small increment between
1/4 and 1/3 of a full turn. Some air and oil should be expelled from the press unit.
Note: If plug leaks oil after tightened,
discontinue use and call BTM to order
a replacement plug.
Loosen plug with
5 mm Allen wrench.
4. The bleeding procedure may need to be repeated several times to expel all of the air.
5. This procedure works best when the press unit is lower than the booster.
6. Check the oil level. Make sure the reservoir is lled so that the oil reaches the bottom thread on
the cap.
BLEEDING THE GUN

5.0 OPERATION
1. Verify that the metals to be joined are the same as specied on the tag afxed to the die
(Also see tooling information on section 6 of this manual).
2. Observe all safety instructions as described previously in this manual.
3. Always hold the unit perpendicular to the work in both directions.
THIS NOT THIS
4. Never attempt to make a Tog-L-Loc/Lance-N-Loc joint through another Tog-L-Loc/Lance-N-Loc joint,
spot weld, or other obstruction.
5. The trigger must be pressed and held throughout the cycle to operate the unit.
6. When metals of dissimiliar thickness are to be joined, the thicker layer should be to the punch
side for best results.
7. The die blade, punch, and stripper must be in place when joining metals. These components are
crucial to join quality.
8. Joint quality is monitored nondestructively by measuring the “button dimension” of the formed joint.
Read QUALITY CONTROL in the Tog-L-Loc/Lance-N-Loc user’s guide for more detailed information.
The button dimension is controlled by adjusting the air pressure (See section 6.1).

6.0 TOOLING
Tog-L-Loc tools are preset by BTM to give best joining results with a specic range of metal type and
thickness, as charted above. Higher strenths for a specic metal thickness may be obtained with
optimized tooling from BTM. All Tog-L-Loc/Lance-N-Loc tools are marked with numbers for easy
identication.
TOOL CHANGE PROCEDURE:
Please note: All tooling changes must be done with the press unit in the “open” position.
Removal of the air supply is required before the tool change or service begins.
Use a 2.5mm allen wrench to change the punch and die in the gun.
PUNCH CHANGE:
1. Remove the retaining screw with an allen wrench. Remove the punch from its pocket (It may be
necessary to pry with a wrench).
DIE CHANGE:
1. Remove the retaining screw with an allen wrench (It may be necessary to pry with a wrench).
2. When installing dies, care has to be taken so the springs are not damaged. Load the die on its
side, bottom rst, then slide the bottom of the die toward the front of the gun carefully, so that the
springs do not bend. Note: If the springs are bent, the die does not function properly and the gun
will form inferior joints.
BUTTON ADJUSTMENT:
Adjustment is achieved by increasing the air pressure to increase button size. Decreasing air pressure
decreases button size. Make tests joints until the desired button dimension is achieved.
TOOLING

6.1 JOINT ADJUSTMENT PROCEDURE
Please read all of the procedure before attempting this on your unit. If not, you may cause damage
to your tooling.
WARNING!
Start button adjustment at the lowerst possible air pressure to avoid damaging
the tooling. Increase the air pressure slowly to achieve a satisfactory joint, or
button size.
PLEASE NOTE: THIS PRESS UNIT USES AN AIR PRESSURE RANGE OF 50-90 PSI
TO ADJUST BUTTON SIZES:
Increase the air pressure to increase button size. Decrease the air pressure to decrease button size.
Button sizes are checked with a “Go-No Go” gage (One should be supplied with your unit, additional
gages can be purchased from BTM).
ADJUSTMENT PROCEDURE:
1. To achieve proper button sizes (As noted in the Tooling Component Record - Section 6.2), start at
the lowest operating air pressure (50 PSI).
2. Gradually increase air pressure, and check the button dimension frequently.
3. Repeat until button dimension is proper, or until you reach maximum operating PSI (90 PSI).
4. Mark air pressure at time of proper button dimension. Operate normally at this air pressure, do
not operate the unit above this air pressure.
(If you reach 90 PSI, and you have not made a proper button dimension, per the Tooling Component
Record, call BTM immediately, DO NOT go over 90 PSI.)
Whenever tooling is changed, test the joints to see that they are still proper. If they are not, repeat
the process above to nd correct air pressure.
