of
the

Check
for

or
binding
of
moving
parts,
cracked
or

DAILY
Sanding
Discs
(part
#14)
must
be
sharp
and
clean
to
perform
properly.
Depending
on
materials
sanded
and
frequency
of
machine
use,
Sanding
Discs
become
clogged
with
wood,
metal
particles,
and
become
dull. Dull
Sanding
Discs
rub
the
workpiece
rather
than
cut,
which
results
in increased
friction,
higher
temperatures,
and
a
burned
workpiece.
As
often
as
possible,
check
the condition
of
the
Sanding
Disc
and,
if
necessary,
replace
a
worn
Sanding
Disc
with
a
new,
10
Pressure
Sensitive
Adhesive
disc.
(See
"To
Attach
A
Sandina
Disc
To
The

Sander'bection
in
this
manual for
further
information.)
4.
DAILY:
With
a
soft
brush,
cloth,
or
vacuum,
remove
all
debris
from
the
Disc
Sander.
Then,
use
a
premium quality,
lightweight

to
lubricate
all
