ASSEMBLY

1. Attach Locking and Bending Handles with Screws or Pins provided.

2. Do not remove Nylon Wedges. These are pre-adjusted at the Factory for locking pressure.

MAINTENANCE

1. Protect working edges and surfaces from scratches, nicks or gouges.

2. Periodically tighten screws and nuts.

3. Keep bottom of F-Bar and top of Rear Hinge clean. This is where the material is inserted and held for bending.

This cleaning operation takes only a few seconds and should be done at least once a day.

4. With the fewest moving parts of any portable brake, only minimum spray lubricant is needed.

TRANSPORTING

1. When transporting your brake, keep it in an unlocked, open position or insert cardboard or another type of

cushioning material between F-Bar and Rear Hinge. This will prevent abrasion and marks, which could trans-

fer to your material.

2. Whether transporting, storing or using your brake, it should be on an even, solid base to prevent possible sag-

ging or bowing.

ADJUSTMENT

NOTE: Your brake has been pre-adjusted at the Factory for even locking pressure at each casting. However, due to

Nylon Wedge wear and/or a wide range of material thicknesses, it may be necessary to readjust lock pressure.

Proceed as follows.

1. Cut scrap siding or aluminum coil stock into approximately 4” square test pieces. All test pieces must be of the

same thickness and one piece is required for each Casting.

2. Unlock brake by pulling Lock Handle toward Operator.

3. Insert 2 inches of the test piece into the brake at each Casting position, then lock brake closed.

NOTE: Brake is properly locked when at surface of Locking Cam is at rest against slope of Nylon Wedge located on

top of Pivot Arm Casting.

4. Try to pull each test piece straight out and determine through feel whether each piece is held with equal pres-

sure.

CASTING ADJUSTMENT: Unlock brake, loosen screw that secures Wedge to Pivot Arm and slide Wedge toward back of brake 1/8 inch. Re-test and repeat Steps 2-6 if necessary. 7. If Wedges are worn and adjustments cannot be obtained, replace all Wedges. 8. If brake is properly adjusted and material continues to slip, material is beyond the brake capacity.
