Safety Interlock System
The MS-5 paper drill is equipped with a safety inter-
lock system which prevents the machine from being
started with the front cover open or the optional drill
guard removed. If the cover is opened or the guard
removed when the drill is in operation, the motors will
shut off and must be restarted when the cover and
guard are back in place. This is a safety feature pro-
vided to prevent accidental contact with moving parts
and must not be tampered with.
Hydraulic Check
Check the hydraulic oil supply for the proper level. This
check is made by removing the rear panel and unscrew-
ing the dip stick located on the hydraulic tank (fig. 4).
The oil level should be no higher than ½” (13 mm) up
from the bottom of the dip stick to allow room for ex-
pansion of the oil when running. Recommended oils
and a cross-reference chart are found in the mainte-
nance section of this manual.
Positioning Drill Heads
Drill heads ordered with your machine have been in-
stalled at the factory. One ¼” drill is supplied as stan-
dard equipment with each head unless otherwise speci-
fied. The MS-5 handles two to five drilling heads
mounted on a dovetail. Each head is independently
adjustable allowing a minimum center-to-center dis-
tance of 1
7 /

" (47.6 cm) to a maximum center-to-center
distance of 15" (381 mm). NOTE: Any number of
heads (up to five) or combination of drill hole sizes
can be drilled at one time. However, when using
½” (13 mm) drills, it is recommended that no more
than three heads be used at the same time.
Always position heads so that the lift of paper being
drilled is centered on the table. Drill heads are mounted
on a dovetail and positioned by a scale mounted on
the front of the dovetail (fig. 5).
To move heads: raise the front cover and release the
drive belt tension by lifting the belt lever. Loosen the
socket head screws holding the head to the dovetail
and position the heads according to the scale (fig. 5).
The dovetail scale is calibrated from the center of the
table and is setup to give readings to the center of the
holes. The scale is read from the outside edge of the
drill heads. (Heads mounted to the right of center read
the scale from the right side, heads to the left of center
are read to the left of the head.) Once the heads are in
the desired position, tighten the socket head screws in
the dovetail.
