OPERATION
(CONTINUED)
While
holding your
sander
firmly
in
front of
and
clearly
away
from
you, with the
sanding
surface
clear
of
any
foreign material,
slide
switch
starting
sanding
action.
Place the
sander
gently
onto
the
work and
move
slowly using forward
and backward
strokes.
DO NOT
FORCE.
The
weight
of
the
unit
supplies
adequate
pressure,
so
let
the
sanding sheet
and
sander
do
the
work.
Applying
additional
pressure
only
slows
the
motor,
rapidly
wears
sandpaper and
greatly
reduces speed. Excessive
pressure
will
overload the
motor
causing
possible
damage
from motor
overheating
and can
result
in
inferior
work
as
any
finish
or
resin
on
wood may
soften
from
the
frictional
heat.
Sanding
with the
grain
of
wood
gives the
smoothest
finish
while
sanding
against the
grain results
in
faster
sanding.
(See
Fig.
5)
The
sander can
move
the length
of
the
entire surface,
however,
do
not allow
sanding on
one
spot too long as
its
rapid
action
may
remove
too
much
material
making
the surface uneven.
Always
remove
sander from
work
piece before
sliding
switch
into
"Off" position
stopping sanding
action.
MAINTENANCE
WHEN
SERVICING
USE
ONLY
IDENTICAL
REPLACEMENT
PARTS.
LUBRICATION
All
the
bearings
in
this tool
are lubricated
with a
sufficient
amount
of
high grade
lubricant for the
life
of
the
unit
under normal
operating
conditions,
therefore,
no
further lubrication
is
required.

After
50 hours
use, the platen with
cushion,
Key
No.
20,
should be
removed
by removing
the four
(4)
screws,
Key
No.
22.
The
bearing
block,
Key, No.
18,
and
slide
on
platen with
cushion should be wiped
clean
and
re-lubricated
with
a
good
grade
of
light
grease.
NOTE:
The
Bearing Block,
Key
No.
18,
is
so
designed
that
when
worn
it
may
be
rotated 90°,
engaging
the platen
lever
in
the
alternate
notch,
thereby
giving a
virtually
new
part.
