Initial Lubrication
this mill has numerous moving metal-to-metal
contacts that require proper lubrication to help
ensure efficient and long-lasting mill operation.
however, some lubrication must be performed
manually. lubricate the spindle and quill before
proceeding to the
Test Run or Spindle break-In
sections.
power Connection
After you have completed all previous setup
instructions and circuit requirements, the machine
is ready to be connected to the power supply.
To avoid unexpected startups or property dam-
age, use the following steps whenever connecting
or disconnecting the machine.

1. Turn the machine power switch OFF.
2. Grasp the molded plug and pull it completely
out of the receptacle. Do not pull by the cord
as this may damage the wires inside.
NOTICE
failure to follow reasonable lubrication
practices as outlined in this manual for your
mill could lead to premature failure of your
mill and will void the warranty.
To lubricate the spindle do the following steps:
1. use the coarse downfeed handle, completely
feed out the quill and lock it in position with
the quill lock. rub the quill down with a lightly
oiled rag.
2. While holding the coarse downfeed handle,
release the quill lock and return the quill to its
initial position.
3. add 6 to 10 drops of oil to the spindle lubri-
cation cup and wait 5–10 minutes (see
figure 14).
Note: The spindle lubrication cup is a gradual
gravity powered system. Extending the quill
at this stage will empty the cup too rapidly to
effectively lubricate the spindle.
