1. Remove blade guard.
2. Loosen, but do not remove, the four fixed
blade cap screws (see
Figure 5).

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 mov-
ing blade, tighten the four fixed blade cap
screws, then re-install blade guard.
5. Test performance of shear on scrap work-
piece.
— 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.
Cleaning
Periodically wipe down the tool with a cleaner,
such as Grizzly Model
T23692 Orange Power
Degreaser, to remove dust and oil.

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.
Figure 4.
Lubrication locations (left side shown).
2. Wipe up any excess oil to prevent dust and
grime build-up.
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 adjust-
ed 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.
