Lubrication

Lubricating the Model T27140 consists of applying oil to the pivoting and sliding surfaces.

To lubricate machine:

1. Apply 3–4 drops of lubricant, such as Grizzly Model T26685 Moly-D Multi-Function Machine Oil-ISO 32, to areas indicated in Figure 4 so that oil penetrates between slid-

ing surfaces. Raise and lower handle several times to disperse oil.

1. Remove blade guard.

2. Loosen, but do not remove, the four fixed

blade cap screws (see Figure 5).

2. Wipe up any excess oil to prevent dust and

grime build-up.

Adjusting Blade

The fixed (lower) blade on the Model T27140 is adjustable to allow for different materials and to compensate for wear to the blades. The blade position is factory set and only needs to be adjusted if there is excessive binding between the fixed and moving blade or if a gap exists between the blades that causes the workpiece to bend, rather than shear between the blades.

The ideal blade adjustment will vary depending on the material and dimensions of your workpiece. Above all, make sure the fixed blade is parallel with the moving blade and contacts it evenly along the entire width.

3. Rotate blade adjustment set screws with

2.5mm hex wrench to fine-tune position of fixed blade (see Figure 5).

— Turning blade adjustment set screw clock-

wise moves fixed blade outward, toward moving blade.

— Turning blade adjustment set screw coun-

terclockwise moves fixed blade inward, away from moving blade.

4. Once fixed blade is set parallel to moving blade, tighten the four fixed blade cap screws, then re-install blade guard.

5. Test performance of shear on scrap workpiece.

— If results are satisfactory (producing a

clean cut with no bending), no further adjustment is necessary.

— If results are not satisfactory, repeat Steps

1–5 until results meet your standards.
