6.0 Installation Guide

6.3 Controls

The control panel is mounted on the top left of the
machine.
The blue TABLE LIGHT push button turns the table light
on and off.
The green START push button turns the spindle and
pump motors on.
The red STOP push button will shut both motors off.
The MS-10B drill is equipped with a safety interlock system that prevents the machine from being run
with the chip drawer removed or the spindle guard up. Also, if the cover is raised or the drawer
opened while the machine is running, the motors will shut off and the machine will have to be re-
started when the drawer and/or cover are back in place. This is a safety feature provided to prevent
accidental contact with moving parts and must not be tampered with.

6.4 Vertical Speed

The vertical speed of the drilling head is adjusted with
a control knob on the front of the machine under the table.
This valve regulates the speed of the drill's downward
travel. Light or soft stocks such as mimeographs, etc. are apt
to wrinkle at high speeds, and the speed should therefore, be
regulated to a point where the best results are obtained .
This is found mostly be "trial and error"
Also, too slow speeds will cause the drill to "burn" through the
paper. If burning or burnishing occurs, either increase the vertical speed
and/or sharpen the drill bits. Slower vertical speeds are recommended
when drilling with the maximum number of heads.

6.5 Assembly

Always disconnect the power when cleaning, servicing, or lubricating your
drill, see Lock Out Procedures, page 4.
The only assembly required is to insert the drill blocks and side guide onto the table and mount the
drill heads in the machine.
