WARNING: Some dust, fumes and gases
created by power sanding, sawing, grinding,
drilling, welding and other construction activities
contain chemicals known to the State of
California to cause cancer and birth defects or
other reproductive harm. Some examples of
these chemicals are:
• lead from lead based paint
• crystalline silica from bricks, cement and
other masonry products
• arsenic and chromium from chemically
treated lumber
Your risk of exposure varies, depending on how
often you do this type of work. To reduce your
exposure to these chemicals, work in a wellventilated area and work with approved safety
equipment, such as dust masks that are
specifically designed to filter out microscopic
particles. For more information go to

Uncrating and Clean-Up
1. Remove the HN-16T from the crate.
2. Carefully clean all rust protected surfaces with
a mild solvent or kerosene and a soft rag. Do
not use lacquer thinner, paint thinner, or
gasoline. These will damage painted surfaces.
3. Lubricate all moving parts of the machine with
light grease, or heavy oil.
4. Carefully move the machine to a well lighted
area and attach to a solid, level work bench.
Notcher Setup
Use a machinist’s level and shims if the notcher is
not level. The notcher has been adjusted at the
factory for proper use of capacity material. During
shipment of this unit the machine may have come
out of alignment.
Blade Adjustment
The (#) in the text refers to the breakdown.
1. Remove the table (8-01) and position the ram
(3-01) to its lowest position.
2. Slightly loosen socket head cap screws (5-03).
3. Use the set screw (7-02) to adjust the
positioning block (7-01). The blade gap should
be approximately 0.002”. As a general rule the
blade gap should be approximately 6% of
stock thickness.
4. Tighten screws (5-03).
Blades
The upper blades (4-01 & 4-02) are fac tory set for
“splay” cutting. This method provides that the cut
begins at the outside of the material.
at this setting is 16 gauge. The notcher is also
The capacity
capable of piercing. To accomplish this,
interchange upper blades end for end so that the
cut begins at the apex or corner of inside out.
Align blades at the point flush and tighten screws.
In the piercing capacity the notcher’s capacity is
reduced to 18 gauge mild steel.
Depth of Cut
Adjust set screw (3-08) to stop the ram at a desired
depth and tighten hex nut (3-07).
Ram Brake
The set screw (3-04) acts as a drag on the ram so
that the blade does not free fall. The screw should
be checked and adjusted as needed.
Opening Throat
The notcher’s throat can be opened by removing
hex socket cap screw (1-08). This will allow
squaring, or shearing. Always replace screw when
notching.
Slitting
Remove the upper left blade (4-02) and mount the
right blade in the splay position, and open the
throat. Always replace screw (1-08) when
notching.
Ram Adjustment
Normal wear on the ram (3-01) may require
adjustment. Loosen set screws (3-04) and evenly
tighten the hex socket cap screws (3-03) until the
ram is snug. Tighten set screws from side to side
until the ram has a proper fit. Lubricate the ways.
Lubrication
Lubricate the ways weekly, and lightly oil machined
surfaces to prevent rust. Lubricate daily oil
pinholes that are located on the eccentric bushing
(2-02), and top of the ram (3-01).
