Alignment
Mark V Model 520
Page 1
Also, remember that your Mark V could possibly go
out of alignment if it is moved to an area with
varying floor levelness. Remember to recheck align-
ment and make needed adjustments after moving
your Mark V, if needed.
ADJUST THE HEADREST LOCK
1.
To check the headrest lock (15), grasp the way
tubes near the tie bar (25) and pull up, as
demonstrated by the right hand in Figure B-
44.
2.
If there is "give" in the lock, unlock the handle
and use a medium Phillips screwdriver to
turn the lock shaft (6)
clockwise,
as done by
the left hand in Figure B-44. If the lock is
difficult to operate, the shaft is too tight. To
loosen, unlock the handle and turn the shaft
counterclockwise.
SAFETY
WARNING
Make sure the speed dial is set to "Slow", then
turn off and unplug the Mark V before performing
any ALIGNMENT procedure.
1. Complete
ALL
of the following procedures–
and then recheck them at regular intervals.
You
MUST
use an accurate combination
square for alignment and adjustment. To
check that your square is accurate, select a
board with at least one straight and true edge.
Place the square against the good edge and
draw a line across the width. Flop the square
over and hold it against the same edge and
draw another line next to the first one. If the
lines are parallel, your square is accurate.
2. All the parts and accessories which support or
guide the stock
MUST
be aligned
parallel
with
or
perpendicular to
the main spindle's
plane of rotation. During the following align-
ment procedures the saw blade (provided in
the accessories box) will represent the main
spindle's plane of rotation.
NOTE
If you have installed casters (optional) on your
Mark V, make sure they are retracted and the legs
on the Mark V sit firmly on a level floor. Do this
now.
