NOTE: For angles greater than 10 degrees, use your
free hand to support the mill head, taking some weight
off the brass worm gears. Doing so will greatly length-
en the life of the worm gears.
The worktable has 5/8-inch T-slots for clamping the
work piece to the table.
Set motor switch to STOP position.
Place the work piece on the table.

!
Make sure the machine base is secured to the floor
before repositioning the mill head. The center of
gravity can shift enough to cause the machine to tip
over, resulting in serious injury to the operator and
damage to the machine.
Loosen four large hex nuts that secure the mill head
to the ram adapter (refer to Figure 18).
1/4 turn should be sufficient to allow the head to
move.
