Repeat the process of loosening the top nut and adjusting the bottom nut on the low
side until the knife blade rests evenly in the cutting plate groove. If the blade is unable
to rest evenly in the groove, follow the section titled “Heating Element replacement” to
swing the hot knife blade assembly out. This will allow for easy visual inspection to
determine if the heating block or knife is warped. While uncommon, this can be caused
by overtightening of the set screw and subsequent damage to the heating element,
resulting in uneven heating and block warpage. Warped blocks will need to be
replaced, as it will be impossible to remove and replace heating elements.

Once satisfactory blade alignment has been achieved, tighten upper and lower nuts,
as well as any others that may have been loosened.
The carrier on these cutters has slots milled in them to allow for vertical adjustment. While rare,
it is possible that enough misalignment is present to require the linear motion block to need
adjusted to allow for correct blade alignment. To do this, loosen the bolts on either side of the
linear motion block so that the entire assembly can be tilted to correct blade misalignment.
This problem is encountered mostly after removal of side plates to replace drive roller.
Cold Knife Cutters:
The TRC 1000 series cold cutter features durable A2 steel blades, ground to a fine apex on
precision grinding machines. These blades can dull, and should be sent back to TRC Industries
for sharpening. Attempting to sharpen the front of the bevel as one would with a typical knife
blade will result in a secondary bevel and poor cut quality. This also may cause the blades to
be impossible to resharpen. For this reason, it is recommended that blades in need of
sharpening be sent back to TRC Industries.
The alignment of these blades is also very important. The Top Blade (CC4-3 and CC7-3) should
not be parallel to the bottom blade (CC7-3 and CC7-5); See the section below on blade
adjustment. Aside from making sure the edges are sharp, blades should be coated in a light
coat of oil, such as sewing machine oil or WD-40 to prevent corrosion. The holes for the Top
Blade Shoulder Bolt (CC-6) should be kept free of debris or dirt, and should be kept lightly oiled
as well to allow for adjustment during operation. These blades can pivot slightly and move
along the length of the shoulder bolt shaft. Because the top blade can move on the shoulder
bolts, it is important that springs be checked periodically.
The top blade springs (CC-7) should also be replaced periodically as they wear out. Springs of
different compression rates may be used to adjust tension on the top blade, although heavier
springs may cause premature wear.
Cold Cutter Blade Adjustment
Cold cutter blade adjustment is critical and sometimes tricky. Some experimenting is required
to get satisfactory results for different types of materials and prevent premature blade dulling.
We recommend the use of Loctite on all screws on the knife assembly to prevent the air
cylinder, shoulder bolts, and other fasteners from coming loose.
