4.0 SETTING UP
Open the cabinet and remove the plastic bag(s) with the operating manual, spare fuses, rubber-
lined coil springs, and black rubber spacer.
Tilt the cabinet, and remove the two bolts on the bottom. They hold the floating base plate to
the cabinet for shipping. Save the bolts and washers in case you have to ship or transport the
mill.
Push the black rubber spacer down over the right rear tapered post. Aluminum spacers have
probably been installed on the front and left rear tapered posts; if there are plastic ties securing
those spacers, remove them. Then push the lined coil springs down on the posts –the long
spring on the front post, and the two shorter springs on the two rear posts. Lift the floating
base plate and place it on top of the springs; each bracket has a pin that fits into the
spring/hose assembly.
Cut the tie that holds down the clamp, and make sure the control cable is plugged into its
receptacle on the right inner side of the cabinet.
4.1 Electrical Hookup
The power inlet, a fuse tray, and the On/Off switch (controlling power to the motor and timer),
are located at the back of the unit. The On/Off switch is a rocker switch marked with a circle (0)
and a bar (|). To turn on the power, press down the bar (|) side of the switch. Before plugging
in the mill, set the power to Off by pressing down the circle (0) side of the On/Off switch, then
plug the power cord into the mill’s power inlet. Plug the mill into a standard 3-prong grounded
electrical outlet; a fused 20-amp circuit for the 115V/60 HZ version is recommended. The mill
uses 10-amp “slow-blow” fuses. The 230V/50 HZ model uses 5-amp “slow-blow” fuses and
comes with a European-style polarized plug; outside of Europe the 230V model’s cord should
be adapted to local requirements.
4.2 Standard Safety Features
Manual Lid Latch: The lid has a manual latch, just below the lid handle, which should be closed
whenever the mill is run. To close the latch, pull the tab up and out, engage it with the lid, and
push the tab down. To open the latch, pull the tab up and out.
Pneumatic Cylinder: When the lid is raised all the way, the pneumatic cylinder braces the lid
open, and keeps it from being closed accidentally or abruptly. However, when raising or
lowering the lid always hold the handle.
Clamp Locking Tab: The clamp is opened and closed by a knob on the end of its threaded shaft.
The locking tab is on the shaft between the knob and the clamp. Whenever the clamp is closed
on a vial, lock the clamp by tightening the locking tab clockwise against the clamp crossbar.
When opening the clamp, first loosen the locking tab.
