9 Electrical and Dust Collection Connections
Hoffmann MU3-series dovetail routing machine are equipped with power cords for 120 volt US household
current.
Connect the power cord to a suitable outlet or, if using an extension cord, use the shortest extension cord
possible. Check to make sure extension is undamaged in safe working order.
Dust Collection
The machines are equipped with a 50mm (2”) diameter dust
collection port, located underneath the router bit. The port is
accessed by carefully tilting the machine forward.
Connect a properly sized suction hose from shop vacuum or
connect the dust collection hose to central dust collection
system.
Proper dust collection should always be used for best results
and to keep the machine and work area as clean as possible.
A minimum suction value of 150 cubic feet per minute is
required.
When using a shop vacuum, we recommend using a model
with build-in “tool trigger outlet” to cycle the vacuum on and off
with the routing machine. This reduces strain on the vacuum,
it greatly reduces noise levels and it extends the life of your
vacuum.
If your vacuum is not equipped with a tool-trigger outlet,
aftermarket accessories are available online from retailers like
Amazon.com, etc.
This is an example of an add-on tool trigger outlet available online.
It is shown as an example only, other models and sizes may be available.

10 Changing Router Bits
ALWAYS DISCONNECT THE ELECTRICAL POWER SUPPLY BEFORE ATTEMPTING ANY SERVICE,
MAINTENANCE OR REPAIR WORK!
Follow proper “Lock-Out / Tag-Out” procedures as specified by the Occupational Safety and Health
Administration “OSHA” if applicable.
1. Verify that electrical power has been
disconnected –keep power cord and plug in your
line of sight.
2. Remove the old chip breaker from
the table recess and discard.
3. Loosen the lock-nut (1) and raise the motor
carriage manually by turning the black star knob
(2) on the right side of the motor carriage. Raise
the carriage until the router bit is approx. 1/4”-3/8”
above the machine table.
4. Loosen the Allen head screw (3) on the underside
of the motor bracket to release the motor.
Carefully slide the motor out toward the back.
5. Use the included open-end wrenches (SW18mm
and SW22mm) to open the ¼” collet nut and
remove the old router bit.
6. Install new bit and tighten collet securely.
7. Distance (German: Einstellmaβ) between tip of router bit and top of collet should be (approximately):
For W-0 router bit: 14.3 mm = 0.563”
For W-1 router bit: 15.5 mm = 0.610”
For W-2 router bit: 17.0 mm = 0.669”
For W-3 router bit: 19.0 mm = 0.749”
For W-4 router bit: 24.2 mm = 0.953”
When installing a new bit try to get close to the listed dimensions but don’t spend too much time trying
to get a “perfect” setting. The final adjustment will be made by moving the whole motor in and out – see
next page!

10 Changing Router Bits - continued
8. Slide the motor all the way into the motor
bracket and tighten the Allen head screw (3 on
previous page) by hand.
9. Loosen the Lock-Screw or Locking Lever (4) on
top of the motor bracket and adjust the motor in or
out by moving the motor fine adjustment knob (5)
10. Use the square stop (6) to set the proper distance.
The stop has three steps in one side (W1, W2,
W3) and one large step machined in the opposite
for W4 router bits.
11. Slide the square stop out of the fence rail and
remove the locking lever, washer and square nut.
Place the stop upside down on the table and push
it tightly against the back fence. Turn the motor
fine adjustment knob (5) until the tip of the router
bit (7) touches the corresponding step.
Use the smallest step for W-1, the middle step for
W-2 and the deepest step for W-3.
12. Tighten the the Lock-Screw or Locking Lever (4)
on top of the motor bracket and lower the carriage
to its home position.
13. Make a test cut and verify proper settings by
inserting a Hoffmann key –adjust setting if
necessary
14. Raise the carriage again and install a new chip
breaker insert. Place a piece of scrap wood over
the insert and slowly lower the running router bit
down through the wood. The scrap wood
eliminates tear out on the surface of the chip
breaker.
15. Hold the scrap wood securely in place and be
aware of the turning bit at all times. Lower the
router carriage by turning the black star knob
slowly. When the motor has shut off, secure the
threaded stem with the locknut.
Important Tip!
Due to its weight, the rear of the motor will tilt downward when the Lock-Screw or Locking-Lever (4) is loosened.
Before using the motor fine adjustment knob (5), lightly re-tighten the Lock-Screw or Locking-Lever just enough
to bring the rear of the motor back up. If the motor is left too loose while turning the adjustment knob,
subsequent tightening of the Lock-Screw or Locking-Lever will bring the motor back to its proper horizontal
position and cause the router bit projection to be off.
Always wear safety glasses when operating this machine!

11 Router Bit Adjustments
Hoffmann Dovetail Keys are designed to create permanent and reliable joints in a wide range of wood
products.
For optimum strength and reliability, it is important to adjust the router bits properly.
X The medium or factory settings for the router bit
projection (measurement “X”) are:
Size W0 2.3 mm 0.0906”
Size W1 3.5 mm 0.1378”
Size W2 5.1 mm 0.2008”
Size W3 6.9 mm 0.2717”
Size W4 12.1 mm 0.4764”
These are the minimum setting at which the Keys will still create a tight joint.
If the material allows, a deeper setting will increase the “draw” or “pull” of the Key.
Incorrect:
If the router bit projection is set too shallow, the Key is not able to pull the
miter faces together. An open joint is the result.
Incorrect:
If the router bit projection is set too far, the Key and/or the material can split
resulting in damage to the material.
Final router bit adjustments are always made by moving the router
motor in or out as needed.
A small movement will make a noticeable difference!
We recommend the use of our Digital Multi Gauge (W20001300)
for precise adjustments.
Tip:
Do not try to fine tune the router bit projection by moving the bit in
or out of the collet –it is much easier, more precise and faster to
move the whole motor instead of only the bit.
Operating and Maintenance Manual

12 Selecting Key Length and Setting Routing Stroke
The machine is equipped with a routing height tape scale
(1) which is attached to the routing height adjustment bar
(2). The scale indicates the height the router bit will
travel into the material.
To adjust the height, simply loosen the top locking lever
(3), move the bar to the desired height and tighten the
locking lever,
Always use the longest Key possible to
achieve a tight joint on the face side of the
workpiece!
All Dovetail Keys listed on our website www.hoffmann-
usa.com have the recommended material thickness
listed.
For example, W2 –5/8” Keys are listed as:
W2 –5/8” Keys for 3/4” and thicker stock
Do not use Keys which are too short as the resulting
joints will not be as strong or tight as they could be.
If correct length Keys are not available, stacking two
Keys is advised.
When using Solid Wood Dovetail Keys it is important to
remember that wood Keys are only intended to be a
decorative item. They should not be used alone as a fastener.
Due to the grain direction and possible dimensional variations
with changes in humidity the inherent strength of wood Keys
is less than that of our plastic Keys.
We strongly recommend to use a plastic Key for strength and
“cap” it with a wood Keys for looks.
Wood Keys are available in 12” lengths and are easily cut
to any length.
A fine toothed handsaw (Japanese Style) is a safe
way to cut wood Keys to length.
For larger quantities we found using a bandsaw with a
fine toothed blade is safer than any type of miter of chop saw.
Always read and follow all safety instructions that came with
your power tools!

miter tip to keyway center with a pencil (we used 25.00mm as
example)
2. Place workpiece on machine and adjust center fence plate until
pencil mark is aligned with Center Line Locator
Display should read the same or very similar to measurement on
caliper (slight variation may be due to reading errors, width of pencil
line, etc.)
If distance shown on display varies by more than 0.5mm, adjust
reference value in Parameter 9 up or down as needed.
