TK 816 Leaf Brake
RECEIVING THE MACHINE
Inspect before signing Bill of Lading.
Upon receipt closely examine the Leaf Brake for damage during shipment. Any loss or damage should
be noted in detail on the delivery receipt and reported to your distributor immediately. Free replacement
from TK International is dependant upon the notation and the Bill of Lading on delivery slip.
INSTALLING THE MACHINE
Locate the Leaf Brake in a well-lighted area on a solid, level floor. The Leaf Brake must be securely
bolted to the floor. Be sure you have adequate room to swing both handles and Bending Leaf.
PRECAUTIONS
DO NOT use the Leaf Brake to bend rods, nails or wires. This will cause damage to the edge of the top
blade. DO NOT exceed the capacity of the Leaf Brake.
OPERATING & ADJUSTMENT OF THE TK 816
Adjusting for Metal Thickness
Clearance for bends is obtained by moving Top Leaf back at bending edge. If material is to be bent is
within four gauges of capacity, move the Top Leaf back twice the thickness of the material. With lighter
material, move Top Leaf proportionately forward if sharper bends are desired.
1. Unclamp Handles (H) slightly.
3. Loosen Top Adjustment Plate Bolt (N). Adjust Top Leaf with Top Adjustment Bolts (L). Tighten
Locking Nuts and Top Adjustment Plate Bolt (N). Clamping pressure of the Links (K) is changed
by adjusting the Nuts. (M)
Duplicate Bends
Adjustable Stop Gauge (O) may be positioned at any point on Rod (P) by means of Lock Bolt (Q) to
limit the degree of bend.
Counterbalance
Counterweight (J) can be raised or lowered on Rod to properly counterbalance the Bending Leaf.
Overbending Adjustment
If sheet bends over further on one side than the other/ set the Top Leaf back on the end where sheet is
overbending.
1. Unclamp Handles (H) slightly on side that is over bending.
2. Adjust Top Leaf with Top Adjustment Bolts (L).
3. Reclamp Handle (H).

4
Creeping Top Leaf Adjustments
Should Top Leaf creep forward when clamping material:
1. Check that brake sets level on floor.
2. Check Top Adjustment Plate (M) and Top Adjustment Bolts and Lock Nuts (L) to eliminate any
movement of step bracket (15).
3. If still creeping, wedge under rear of Leg (A) at end that creeps until stopped. Replace wedge
with permanent block of correct height.
Capacity:
The bending capacity of the brake is determined by the bending edge thickness provided by the Bending
Leaf Bars (U/V) when mounted on Leaf.
1. Insert Bar (U) with Angle Bar (V) allow the full rated 1" minimum flange on capacity material.
2. Insert Bar alone without Angle Bar reduces capacity of brake four gauges.
3. Removing both Insert Bar and Angle Bar reduces capacity of brake seven gauges. These Bars are
removed only to make narrow offset bends.
Narrow Offset Bends
Remove Angle Bar (V) and Insert Bar (U) - use Bending Leaf only.
Cautions
Bend short pieces of material in center of brake to equalize the strain. Never bend against seams unless
Links (K) are adjusted to clamp the full multiple thickness of seam; and Top Leaf is set back for clearance
of the same full multiple thickness. Always have both Angle Bar (V) and Insert Bar (U) mounted to Lead
when making capacity bends. When forming sections of wide girth such as cornices, to equalize the
buckles in the sheet:
1. Start bend near the center of sheet, or,
2. Make a kink in the opposite end of sheet from the bend first made.
Sheets are not always perfectly flat and a buckle left in one end while the other is straightened by clamping
in the brake will throw the first bend out of line when it, in turn, is straightened.
Always use material with square-sheared edges - rolled-edges will cause material to bow.
Never use brake to bend rods - these will nick Nose Bar. Always adjust for differences in the metal
gauges. N ever force-clamp the material.
Lubrication
Lubricate occasionally with SAE-30 oil.
