Summary Manual Mark V Model 520
2. Mount the sandpaper on the sanding disc. If
you are mounting sandpaper for the first
time, clean the disc with denatured alcohol
and a clean rag to remove the protective oil.
Otherwise the sandpaper will not stick. Press
the sandpaper firmly on the disc and smooth
it from the center toward the edge.
NOTE
To remove worn-out paper, peel it off the disc.
Then clean the disc with denatured alcohol. To
make it easier to remove the sandpaper, heat the
sanding disc in an oven at a maximum temperature
of 150° (in a convential oven).
3. Position the headstock so that you can reach
the main spindle.
4. Mount the lower saw guard on the main
spindle and open it up by loosening the
cover lock knobs and sliding the cover to the
right. Tighten the guard lock knob.
5. Mount the sanding disc all the way onto the
main spindle. Tighten the setscrew against
the flat of the spindle. Move the guard cover
towards the disc until it is 1" away. Tighten
the two knobs.
6. Position the table 1/16" away from the disc
1/2" away if you are going to use the quill
feed. Adjust the table height so that the table
surface is slightly above the center of the
disc.
7. Check all locks. The table tilt lock, carriage
lock, table height lock, headstock lock and
quill lock (if not used) should be securely
tightened.
WARNING
Do not attempt to move the headstock when the
machine is in the vertical position; the headstock
could fall on you.
Setting Up
the Vertical Drill Press Mode
1. Turn the speed dial to "Slow", then turn off
and unplug the Mark V.
2. Position the headstock 10" away from the
headrest (right side), and the carriage 20"
away from the base mount. Tighten the
headstock and carriage locks. DO NOT
OVER TIGHTEN.
3. Position the worktable surface just above
the top of the headstock. Tighten the table
height lock. Then loosen the tilt lock and tilt
the table to the left 90°. Tighten the tilt lock.
4. Mount the drill chuck all the way onto the
main spindle. Tighten the setscrew against
the flat of the spindle.
5. Loosen the headrest lock. Grasp the way
tubes with both hands, one hand to the left
of the headstock and the other to the right,
then raise the machine into the vertical po-
sition. Tighten the base lock, rock the way
tubes side-to-side. Retighten if possible.
This helps to take the play out of the base
pivot and keeps the Mark V from wobbling.
NOTE
The base lock does not fit dead center in the hole,
but off to one side, as shown in Figure B-131.

6. Move the quill feed handle to the back of the
headstock if you desire.
7. Mount a drill bit in the chuck and tighten
with the chuck key.
WARNING
Never leave the key in the chuck. Remove the key
immediately after securing the bit.
Also, do not attempt to move the headstock when
the machine is in the vertical position; the head-
stock could fall on you.
8. Check all locks. The table tilt, carriage, table
height, headstock and quill (if not used)
locks should be secure.
