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.
