Specifications
1. Overloading this tool can cause injury
from flying parts if tool breaks. Do not
exceed tool capacities.
2. NEVER operate bench shear without
plastic safety guard in place.
3. Always chamfer and de-burr sharp
sheet metal edges after cutting. Sharp
edges on sheet metal can result in
severe cuts.
4. NEVER place your fingers or hands
between shear blades. Amputation or
severe cuts can easily occur!
5. Always wear leather gloves and
approved safety glasses when using
this tool.
6. Inspect bench shear for any cracked
components or loose fasteners. Correct
any problems before use. Loose hard-
ware or cracks could result in sudden,
unexpected movements during use.
7. DO NOT allow children to have unsper-
vised access to bench shear.
Damage to your eyes and hands could
result from using this tool without proper
protective gear. Always wear safety glasses
and heavy gloves when operating this tool.
If you have never used this type of machine
or equipment before, we strongly recom-
mend that you read books, trade magazines,
or get formal training before beginning any
projects. Regardless of the content in this
section, Grizzly Industrial will not be held
liable for accidents caused by lack of train-
ing.

shear blades with cut line marked on work-
piece.

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.
Tools Needed: Qty
Hex Wrench 4mm .............................................. 1

To adjust blade:
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.
