hello and welcome to this informal tip
video on the bosch professional glide
sorts of 12-inch gliding Mitas all with
a patented axial glide mechanism on the
back and what we're going to show you in
this short video is just to how how to
check the alignment of the blade at zero
bevel so what we've done with this
particular machine is deliberately miss
adjusted it we've got a a square resting
on the aluminium base very important to
have the square on the aluminium and not
resting on the plastic here which could
cause an error in the measurement and
you can see as we go up there there's a
massive gap there between the blade and
the and the back of the gauge there at
the back of the square so we're going to
correct this
there is a procedure outlined in the
manual which is fairly straightforward
the first thing you have to do is to
release the the front locking lever here
of course if you've got that lock down
we have this forward locking lever that
needs to be released and then as per the
instructions we go around the back of
the machine
and we have a couple of locking bolts
there a 10 millimeter bolt they're
numbered
I think 68 yet so there's two of them
there so just use a socket or a drill
driver there on it to loosen those off
okay and then the next thing we need to
do before any adjustment can be made
it's the loosen off grub screw it's I
think it's a four mil allen screw we
marked on the machine here number 70
because that correlates with what's in
the manual so we loosen off number 70 by
by three turns and then we're ready to
go now it's very important to note that
the top screw number 69 that's the one
that the head of the saw is resting on
that's if you like your reference screw
so when you tighten that it will correct
the error we put on this saw in the
correct direction so it will actually
move the head of the saw to your right
or to your left as you can see it as
we're viewing it in the movie so
tightening that top screw there will
actually bring the head up right and
hopefully it will get the saw perfectly
at zero so that it's touching the the
gauge of the square firmly so got a nice
flush fit there the cameras picking that
up it's also important to notice that
the the gauge there that the square is
is is kissing the the core of the blade
and to make sure that you've got that
between teeth at the bottom there don't
have it resting on a tooth make sure
you're going in to a gap between the
teeth otherwise again your adjustment
your reading might be affected the other
thing of course is that because that's a
set screw because that's a stop
effectively on the back that top allen
screw you do need to physically push the
head of the saw over to your left as
you're looking at it and then bring it
back again firmly on to the stop and
double-check that the alignment is still
correct
also if the error is to the left as we
look at it in the video and you need to
correct it to the right it's very
important to note that that top screw
will not move the head to your right
okay it'll create space for that
movement but you do need to push the
head of the machine in the direction of
that stop so I'm hoping that's not too
confusing to see as you can see now
we've got a nice flush fit there between
the square and the blade and so we can
now lock this down so I think it's some
front locking lever down okay to
stabilize the whole thing and then we
just basically reverse what we did to
start with so we tighten number 70 at
the bottom there okay so that's the
lower grub screw the allen screw okay
just tighten that up not too much and
then finally to make it all stable with
the
m10 bolts and and that should do it but
please remember that top screw only
moves the head to the left if you want
to make a correction to the right if
that's where your error is then you do
need to loosen that top screw and push
physically on the side of the machine
the head against the stop so hope you
hope you find that useful it's a very as
I say informal movie but it's a fairly
straightforward procedure thanks for
watching
