Techniques and examples explained are not intended to be fully-exhaustive and definitive. The best method depends on the specific construction of the building
worked on, the brand and type of material used, and the particular skills of the applicator.

Basic-Note: Use parts sheet for reference number clarification.

1. Mark both ends of material to be bent (use pencil, punch or snips). 2. Insert material in brake to marks, lock brake by pushing Lock Handle (15) all the way
to the stop position. 3. Bend to desired angle in one continuous, smooth motion. NOTE: During bend, hold Bending Handle equal distance from ends of Handle. If over bend on one end occurs
while standing at center of brake, move your body in opposite direction of over bend.

Note: The above shapes are based on common profiles used on many job sites. The exact measurements of each bend may vary from job to job, trim piece to trim
piece. We recommend taking a few moments to familiarize yourself with the basic functions of the brake. Practice making bends with scrap or left over material until you are satisfied with the
results.

Maintenance
|
1. When scoring material, be mindful of knife damage to hinge area by scoring past the ends of material.
2. Protect working edges and surfaces from scratches, nicks or gouges.
3. Periodically tighten screws and nuts.
4. Keep bottom of L-Bar (No. 3) and top of Rear Hinge (No. 6) clean. (This is where material is inserted and held for bending). This cleaning
operation takes only a few seconds, and should be done at least once a day.
|
|
Lubrication
|
1. Regularly remove old grease and dirt.
2. Use fine sandpaper or emery cloth on bottom of Slide Bar (1) and top of L-Bar (3). These surfaces should be fairly smooth to the touch.
3. Re-lubricate these surfaces using medium grade oil, silicone spray, lithium #2 grease or similar lubricant.
4. Top of Wedges (17) and Wedge Block (18) can be lubricated with petroleum jelly or light waterproof grease.
|
|
Transporting
|
1. When transporting your brake, keep it in an unlocked, open position, or insert cardboard or other cushioning material between L-Bar (No. 3) and Rear Hinge
(No. 6). This will prevent abrasion and marks which could transfer to your material.
2. Whether transporting, storing or using your brake, it should be on an even, solid base to prevent possible sagging/bowing.

Adjustment (perform Lubrication step above first)
|
1. Unlock brake slightly, to opening of approximately 1/16 inch
2. Cut aluminum coil stock into approximately 2 x 2 inch pieces.
Test pieces must all be of the same thickness and are required for each C-Member (ie:T850 requires 4, T1050 requires 5, etc.).
3. Insert test pieces about halfway into the brake at each C-Member position, then lock brake in closed position.
4. Try to pull each piece straight out. If test piece feels snug or is held tight, no additional adjustment is required. If test piece pulls easily out,
adjustment is required.
5. Total and simultaneous adjustment at all C-Members (No. 24).
6. Unlock Brake fully.
7. Remove Clevis Pin and Cotter that connects Locking Handles (No. 19) to Lock Handle Clevis (No. 22).
8. Loosen Hex Jam Nut located next to clevis.
9. To reduce locking force, rotate Clevis clockwise 1/2 revolution. This will shorten overall length of Clevis Assembly. To increase locking force, rotate clevis counter clockwise 1/2
revolution. Re-test per Clamp Test Procedure.

Individual C-Member Adjustment
|
1. After determining C-Members that require additional adjustment, disassemble as per instructions in Lubrication section.
2. Remove and replace the wedge at the station requiring adjustment or make a shim piece from coil stock the same shape as the Wedge. Punch 2 holes in shim for screws, and re-install Wedge
with shim in-between Wedge and Slide Bar. You have now raised the Wedge.Re-test via Clamp Test Procedure.
|
Note: The toggle locking principle does not require much locking pressure to generate a great deal of locking force. That is, when adjusted
properly, the handle should be very easy to lock, almost to a point of feeling too loose, and still provide much holding power.
