4. Maintenance .......................... 20
5. Stability of Machine
If there is any tendency for the machine to tip over
or move during certain operations such as when
sanding long heavy boards, the sander should be
bolted down.
6. Location
The machine should be positioned so neither the
operator nor a casual observer is forced to stand
in line with the sanding belt or disc. This machine
is intended for indoor use only.
7. Kickback
When sanding on the Disc, always apply the work-
piece left of center to the left side of the disc. Ap-
plying the workpiece to the right side could cause
it to fty up (kickback) which could be hazardous.
8. Protection: Eyes, Hands, Face, Ears and Body
a. Always wear safety goggles (not glasses)
that comply with ANS1 Z87.1, Wear face shield
if operation is dusty, Wear ear plugs or muffs
during extended periods of operation, Do not
wear gloves, jewelry or watches. Roll long
sleeves above the elbow. Tie back long hair.

MOUNTING BELT AND DISC SANDER
TO WORKBENCH
If belt and disc sander is to be used in a permanent
location, it should be fastened securely to a firm sup-
porting surface such as a workbench. A 5/16" bolt, flat-
washer, Iockwasher, and hex nut (not included) should
be used at each mounting hole to secure the belt disc
sander to the workbench.
If mounting to a workbench, holes should be drilled
through supporting surface of the workbench as follows:
1. Set the belt disc sander on the workbench in the
exact position where it is to be mounted,
2, Push a pencil through one of the mounting holes
and place a mark on the workbench that marks the
center of the mounting hole opening. Mark the other
three mounting hotes using the same method.
SPECIAL NOTE: Make sure the pencil marks are
placed very near the center of the mounting hole
openings,
WARNING: Check under workbench before drilling
holes to make sure electrical wires, gas pipes, etc.,
will not be hit by drill bit.
3. Remove the belt disc sander from the workbench.
Drill four 3/8" diameter holes using the pencil marks
as the center of the drilled holes.
SPECIAL NOTE: It is highly recommended that you
place a soft foam pad between your belt disc sander
and workbench. The use of this pad will reduce noise
and vibration.
4. Place the belt disc sander back on the workbench.
Align the mounting holes in the sander with the
drilled holes in the workbench.
MOUNTING HOLES
.
6,
Insert four 5/16" bolts through the mounting holes
and through the dritled holes in the workbench.
Place a 5/16" flat washer, 5116" lockwasher, and a
5/16" hex nut on the bolt and tighten,
SPECIAL NOTE: Do not overtighten mounting
bolts - leave some cushion in the foam pad for ab-
sorbing noise and vibration.

7. If you prefer to mount your sander to a leg set we
recommend the leg set for bench top tools which is
available through Sears Retail or Catalog Stores,
The number of this leg set is 9-22244. This leg set
is an optional accessory and instructions to mount
the belt and disc sander to this leg set are included
in the leg set package.
ALTERNATE MOUNTING METHOD
An alternate method of mounting the belt and disc san-
der is to fasten the sander to a mounting board. The
board should be of sufficient size to avoid tipping of
sander while in use. Any good grade of plywood or
ch_pboard with a 3/4" minimum thickness is recom-
mended. (Thinner chipboard can break.)
1, Follow instructions for mounting sander to work-
bench, substituting a board 18" X 24" minimum size
in place of the workbench.

and remove plug from power source outlet before
adjusting, maintaining, or lubricating your belt and
disc sander.
f power cord s worn or cut, or damaged in any way,

Frequently blow out or vacuum out any dust that may
accumulate inside the motor.
A coat of automobile-type wax applied to the worktable
will make it a little easier to feed the work while finishing.

the belt could pick up the wax and deposit it on the
pulleys, causing the belt to slip.

The BALL BEARINGS in this machine are packed with
grease at the factory. They require no further lubrica-
tion.
