additional safe,/instructions for
beUt and disc sander
Safety is a combination of operator common sense and
alertness at all times when the finishing machine is being
used,
WARNING: FOR YOUR OWN SAFETY, NO NOT
ATTEMPT TO OPERATE YOUR FINISHING
MACftlNE UNTIL IT IS COMPLETELY ASSEM-
BLED AND INSTALLED ACCORDING TO THE
INSTRUCTIONS . . . AND UNTIL YOU HAVE
READ AND UNDERSTOOD THE FOLLOWING.

2. Getting To Know Your Sander ................. 18
3 Basic Machine Operation .......................... 21
4. Maintenance ............................ 23
5.. Stability Of Machine
If there is any tendency for the machine to tip over or
move during certain operations such as when finishing
long heavy boards, the sander should be bolted down
6 Location
The machine should be positioned so neither the opera-
tor nor a casual observer is forced to stand in line with
the abrasive belt or disc This machine is intended for
indoor use only
7. Kickback
When finishing on the Disc, always apply the workpiece
to the "Down Side" of the disc, Applying the work-
piece to the "Up Side" could cause it to fly up
(kickback) which could be hazardous
8 Protection: Eyes, Hands, Face, Ears, Body
a Wear safety goggles that comply with ANSZ87 1-
1968, and a face shield if operation is dusty Wear
ear plugs or muffs during extended periods of opera-
tion
b, Do not finish pieces of material too small to hold by
hand
c, Avoid awkward hand positions, where a sudden slip
could cause a hand to move into the abrasive disc or
belt
d. Never climb on the machine
e. Never turn your Sander "ON" before clearing the
table(s) or work surface(s) of all objects (tools,
scraps of wood, etc) except for the workpiece and
related feed or support devices for the operation
planned
f Make sure the abrasive belt runs in the right direction
Always have the tracking adjusted correctly so that the
belt does not run off the pulleys
g. Hold the work firmly when finishing on the abrasive
belt and against the worktable when finishing on the
disc
h Always adjust the worktable to within 1/16 in of the
abrasive disc or belt
When finishing a large piece of material, make sure it
is supported at table height,
Never leave the machine work area with the power on,
before the machine has come to a complete stop, or
without removing and storing the switch key
k Never operate the machine with protective cover on
the unused shaft end of the motor removed
9. If any part of this belt disc sander should break, bend,
or fail in any way or any electrical component fail to
perform properly, or if any is missing, shut off power
switch, remove power supply cord from power supply
and replace damaged missing and/or failed paris before
resuming operation

outward, it puts TENSION on the belt
3 Place both of the 1/2" wrenches on the ADJUSTING
screws and pull the wrenches toward you This will
stretch the belt Move the wrenches back and fortha
few times so that you "get the feel of the belt while
it is stretching (TENSIONING)

basic operation
SURFACE FINISHING ON THE BELT
FLAT SURFACES
Hold the work piece firmly with both hands, keeping your
fingers away from the belt
Keep the end butted against the backstop and move the
work evenly across the belt Use extra caution when fin-
ishing very thin pieces
For finishing long pieces, remove the backstop
Apply only enough pressure to allow the belt to remove
material If the belt stalls and the belt pulleys slip while
applying moderate pressure to the worl<piece, the belt re
quires more tension
\
END FINISHING ON THE BELT
It is more convenient to finish the ends of long work-
pieces with the belt in a vertical position,
Move the work evenly across the belt For accuracy, use
a miter gauge
The table may he tilted for beveled work
See Getting To Know Your Finishing Machine section
for adjusting the belt table and the work table

FINISHING SMALL END SURFACES AND
CURVED EDGES ON THE DISC
Move the work across the "Down Side" of the face of the
disc For accuracy, use a miter guage.

maintenance
WARNING: FOR YOUR OWN SAFETY, TURN
SWITCH "OFF" AND REMOVE PLUG FROM
POWER SOURCE OUTLET BEFORE ADJUST-
ING, MAINTAINING, OR LUBRICATING
YOUR FINISHING MACHINE.
Keep your machine and your wolkshop clean The dust
traps around the disc ancl the belt are designed to deflect
most of the fine dust They should be connected to a
Home-N-Shop Vac for most efficient dust removal
WARNING: DO NOT ATTACH A HOME-N-
SHOP VAC WHEN FINISHING IRON OR
STEEL. THE SPARKS COULD IGNITE THE
DEBRIS AND CAUSE A FIRE.
If power cord is worn or cut, or damaged in any wav.
have it replaced immediately
Frequently blow out any dust that may accumulate
inside the motor
For motor maintenance, follow instructions furnished
with motor
A coat of automobile-type wax applied to the worktable
will help prevent rust and make it a little easier to feed
the work while finishing
Do not apply wax to the belt table because the belt
could pick up the wax and deposit it on the pulleys,
causing the belt to slip
