3. Remove adjusting tools. Form habit of checking to see that adjusting tools are removed before using machine.
4. Keep all parts in working order. Check to determine that the guard or other parts will operate properly and perform their intended function.
5. Check for damaged parts. Check for alignment of moving parts, binding, breakage, and, mounting or any other condition that may affect a tool’s operation.
6. A guard or other damaged part should be properly repaired or replaced. Do not perform makeshift repairs. ( Use parts list provided to order repair parts.)

KNOW HOW TO USE TOOL

1. Use right tool for job. Do not force tool or attachment to do a job for which it was not
   designed.

2. Keep hands and clothing clear of brake nip joints.

3. The maximum capacity if this machine is 14gauge (0.070＂) mild steel or equivalent. Exceeding capacity may be dangerous to operator and cause damage to machine.

4. Bolt machine to floor to prevent sliding or tipping of machine.

5. Keep bystanders away from area of counterweight movement.

6. Do not attempt to bend round bars-damaged to machine will occur.

7. Work piece must have square-sheared edges. Rolled edges will cause work piece to bow.

1. When the bending leaf (Figure 3, Ref.No.64) is at the bottom dead center position, the edge of the bending leaf must be flush with the beam edge. To adjust, loosen socket head bolts (Figure 3, Ref. No.59), turn hex head bolts (Figure 3, Ref. No. 57) as needed, and retighten the mounting bolts. If the leaf has been adjusted flush on both ends, but is not flu shin the center, adjust nuts located in the center of the beam and bending leaf until center is aligned.

2. Adjust the clamping leaf (Figure 2, Ref. No. 7) to the work piece thickness. Pull both clamping handles (Figure 2, Ref. Nos. 4 and 9)forward and loosen lower hex nuts (Figure2, Ref. No. 29) so that the clamping leaf rests on the beam (Figure 2, Ref. No. 36), but is not under pressure. Rotate hand wheels (Figure 2, Ref. No. 35) so that the front edge of the nose on the clamping leaf is set back from the beam edge equal to the thickness of the workpiece. Minimum distance is work piece thickness. Clamping leaf can be set further away from table edge to produce a larger radius bend. Make sure to adjust the hand wheels equally, so that the clamping leaf edge is parallel to the beam edge. The lower hex nuts will be tightened after the next step.

3. Adjust the clamping pressure. Place sample of the work piece on the table and move the clamping handles forward. Work piece should be held firmly in position. To adjust for more or less pressure, unclamp the work piece and adjust the upper hex nuts (Figure 2, Ref. No. 29)and re-clamp until the desired pressure is obtained. Tighten lower hex nuts securely.

4. If pans or boxes are to be formed, adjust the nose bar (Figure 2, Ref. Nos. 25-28) on the clamping leaf to the length of the bend required and remove the nose pieces on each side of
   the bend to allow clearance for the work piece. Loosen socket head bolts, (Figure 2, Ref. No. 15), remove or reposition nose bar, then tighten bolts.

5. Raise the clamping leaf by moving clamping handles back. Place work piece on beam and position where bend is required at edge of beam. Clamp leaf onto work piece by pulling clamp handles forward. Do not use pipe extensions on the clamping handles.

6. Slowly pull up bending leaf by the operating handles (Figure 3, Ref. No. 71) until desired angle of bend is obtained, continuing bend slightly to allow for material spring back. Each material has its own rate of spring back, so a trial and error process is necessary to achieve the required bend. Use only operating handles to raise bending leaf. Do not use the counterweight rods to raise bending leaf-damage may occur to leaf hinge.

7. For repeat bends, the collar (Figure 2, Ref. No. 39) is located at the desired position on the guide rod (Figure 2, Ref. No. 37) and secured by the set screw (Figure 2, Ref. No. 44).

8. When bending against seams set back clamping leaf and adjust clamping pressure to allow for the multiple thickness of the seam

Maintenance

Refer to Figure 2.

LUBRICATION

Use medium weight, non-detergent oil.
MONTHLY:
Oil the bending leaf pivot joint through the oil fittings (Figure 2, Ref. No. 5) located at the right and left pivot points.
MONTHLY:
Oil the clamping handle bearing surfaces through oil fittings (Figure 2, Ref. No. 5) on top of links (Figure 2, Ref. No. 6). Coat all exposed iron surfaces to prevent rusting.
