SAFETY PRECAUTIONS
If you do not have a manual, contact the
manufacturer and obtain one before using any
power tool.
Always use proper guards and safety devices
when operating power tools and machinery.
Carefully check table saw blades before each
use.
Do not use if damage or defect is suspected.
Do not wear loose clothing or jewelry that may
catch on tools or equipment.
Unplug the tool or machine when mounting or
making any adjustments to mechanical
performance.
Important Safety Precautions
A)Personal Safety
i) Stay alert, watch what you are doing and use common
sense when operating a tool. Do not use a power tool while
you are tired or under the influence of drugs, alcohol or
medication. Serious personal injury could result if complete
attention is not given while operating power tools.
ii) Always wear safety glasses. Everyday eyeglasses are
not safety glasses. Safety glasses have specially constructed
frames, lenses and side shields for better protection.
iii)Use safety equipment. Use a face or dust mask when
the cutting operation is dusty. Safety equipment such as dust
masks, hard hats, non-skid safety shoes and hearing
protection reduces personal injuries when used for
appropriate conditions. If devices and tools allow for dust
extraction and collection, ensure these are connected and
properly used.
iv) Do not overreach. Keep proper footing and balance at
all times. This allows for better control of the power tool in
unexpected situations.
v) Never stand on the machine. Serious injury could occur if
the tool tips or if the cutting tool is unintentionally contacted.
vi) Secure workpieces. Use clamps or vises to hold work
when practical. This is safer than using your hands and frees
both hands to operate the tools
vii) Dress appropriately. Do not wear loose clothing or
jewelry. Ensure you keep clothing, hair and gloves away from
moving parts. Loose clothing, jewelry or long hair can be
caught in moving parts. Roll up long sleeves to the elbow.
Wear protective hair covering to contain long hair.
viii) Avoid accidental starting. Ensure the switch is in the
off position before you plug it in. Carrying a power tool in
your hands with your finger on the switch or plugging in a
power tool that has the switch on is inviting accidents.
ix) Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool could result in personal injury.
B) Work Area Safety
i)
switches, or remove starter keys. ii) Keep work area clean
and well lit. Clutter and/or dark areas encourage accidents
ii)Keep children and bystanders away while operating a
power tool. Complete attention is required when operating a
power tool.
C) Electrical Safety
i) Ground electrical tools. If the tool is equipped with a
three-prong plug, it must only be plugged into a grounded
three-hole electrical outlet. If required, a qualified elctrician
can install one. Never remove the third prong or modify the
plug that is provided in any way.
ii) Never expose a power tool to rain or wet conditions.
You will increase the risk of electric shock if water enters the
powertool.
iii) Using power tools in damp or wet locations or conditions
is extremely dangerous.
iv) Do not operate any power tool in an explosive
atmosphere, in the presence of flammable liquids, gases or
dust. Power tools can create sparks which may ignite the
fumes or dust.
When using the JessEm Mite-R-Excel II™ in
conjunction with any other tool, first read and
follow all instructions and safety information in
that tool's owner's manual.
When using the Mite-R-Excel II™, always keep
your hands clear of the cutter and the line of cut.
Always turn off the power and make sure that the
cutter comes to a complete stop before changing
the setting of any part of the Mite-R-Excel II™
Always securely tighten the large clamping knob
before starting any cut.
Always wear safety glasses, hearing protection,
and follow all normal shop safety practices.
After making any adjustments to the miter angle
of your Mite-R-Excel II™, always verify safe
clearance between the cutter and all parts of the
JessEm Mite-R-Excel II™
Always wear eye protection in compliance with
ANSI safety standards when operating any
power tool.
Make your workshop child proof. Use padlocks, master

Before operating any machinery or
power tool, read and understand all
safety instructions in the owner’s
manual that came with that tool's
owner's manual.

Assembly Instructions
Step 1: Assembly of the Flip Stop
a. Using the 5/32" hex key, attach the flip stop upper
(Part #20) and the flip stop lower (Part #13) using
(1) ¼-20 x ½" button head cap screw (Part #17)
and (1) ¼-20 x ¾" button head cap screw (Part
#18) along with (2) ¼” x 5/8" washers (Part #19).
See Figure 1
b. Attach the clamping handle (Part #11) along with
(1) 1/4" x 5/8" washer (Part #19) to the flip stop
assembly using the Flip Stop T-Bolt - Short (Part
#35) as shown in Figure 1.
a. Loosen the clamping handle (Part #11) and slide the Flip Stop T-Bolt - Short (Part #35) into
the T-slot on the Fence Extrusion (Part #33). See Figure 2

The following instructions are for assembling the Mite-R-Excel II™. Please note that the Mite-R-Excel II™
is factory set and only assembly is required.

b.
Step 3: Assembling the Mite-R-Excel II™
a. Slide the 3/8" x 1" Stainless Steel Washer (Part #41) onto the Handle (Part #10) and thread the
handle into the guide bar (Part #56) as shown in Figure 3.
Step 4: Setting/Tightening the Guide Bar in the Miter Slot
** NOTE ** Since all miter slots are machined differently, it is important to set the
guide bar so that it moves smoothly during operation. If after following our directions
below, you notice a tight spot on the miter slot, you can either file or stone off the
high spot on the Miter Slot in your table saw or reset the Mite-R-Excel II™ in that area.

Step 5: Attaching the Fence Extrusion to the Mite-R-Excel II™ Assembly
**NOTE ** The Fence Locating Pin Knob was designed to always allow for the user to
keep their fence properly referenced from the blade when the gauge is set to 0 degrees.
Not all table saw are the same. The instructions below will allow you to properly
reference the fence to suit your needs.
a. Pull the Fence Locating Pin Knob (Part # 40) back and loosen
both Fence Knobs (Part #45). Slide the fence extrusion through
both of the Fence Clamping T-Bolts - Long (Part #64). See
Figure 5.
Once the extrusion is through both T-Bolts,
line up the Fence Locating Pin Knob (Part
#40) with the 6 inch mark on the ruler
(See Figure 6). Push the knob forward to
engage it as you slowly slide the fence
towards the blade. At roughly the 6-1/8"
mark on the ruler, (See Part 32 in Figure 6)
the locating pin will engage with the preset
Fence Locating Nut in the fence extrusion.
When the locating pin is engaged, tighten
both fence knobs.

Using the 3/32" Hex Key provided, attach the hex key extension (Part #63) to the Hex Key Figure
9A and insert the hex key into each of the two holes next to the Fence Locating Pin Knob and
loosen the #10-32 x 3/16" Flat Point Set Screws (Part #37). See Figure 9
Add a 3" block of wood in between the blade and flip stop (See Figure 8). **Note: You can use any
size of wood you may have lying around your shop for this step, just be sure to set your flip stop to
the appropriate length **
Slide the fence extrusion either closer or further away from the blade until the block of wood
touches the blade. The distance from the Fence to blade should be roughly 1/16" once the fence
is adjusted.
Once the fence is set, using the 3/32" Hex Key and the hex key extension provided, tighten both
of the #10-32 x 3/16" Flat Point Set Screw (Part #37)

How to Set the Vernier Scale
The Mite-R-Excel II™ can be used not only with whole numbers, but is also designed to move 1/10th
degrees on the lower Vernier Scale.
Loosen the Handle (Part #10)
Pull out and lock the Indexing Pin Knob (Part #5) and rotate the gauge to the nearest whole
number.
Using the lower Vernier scale, set your gauge to the 1/10th degree desired.
Once you have your setting, lock only the Handle only (part #10), leaving the Indexing Pin Knob
(Part #5) in the disengaged positon. See Example 1
