SPECiFiC
SAFETY INSTRUCTIONS
FOR BELT / DiSC SANDER
For your own safety, do not try to use your belt / disc sander
or plug it in until it is completely assembled and installed
according to the instructions, and until you have read and
understood this instruction manual:

THIS SANDER IS DESIGNED TO SAND WOOD OR
WOOD-LIKE
PRODUCTS ONLY. Sanding or grinding
other materials could result in fire, injury or damage to
workpiece.
USE sander on horizontal surfaces only. Operating
the sander when mounted on non-horizontal surfaces
might result in motor damage.
TO STOP it from tipping over or moving when in use,
the sander must be securely fastened to a bench top
or supporting surface.
PLACE the sander so neither the user nor bystanders
are forced to stand in line with the abrasive belt or disc.
MAKE SURE the sanding belt is installed in the correct
direction. See directional arrow on back of belt.
5,
6.
ALWAYS have the tracking adjusted properly so the
belt does not run off the pulleys.
7.
DO NOT USE sanding belts or discs that are damaged,
torn, loose. Use only correct size sanding belt and disc.
Narrower belts uncover parts that could trap fingers.
8.
MAKE SURE there are no nails or foreign objects in
the part of the workpiece to be sanded.
9.
ALWAYS HOLD the workpiece firmly when sanding.
Keep hands away from sanding belt or disc. Sand
only one workpiece at a time.
10. ALWAYS HOLD the workpiece firmly on the table
when using the disc sander and when using the belt
sander.
11. ALWAYS SAND ON THE DOWNWARD SIDE of the
sanding disc when using the disc sander. Sanding on
the upward side of the disc could cause the workpiece
to fly out of position, resulting in injury.

ALWAYS maintain a minimum clearance of 1/16 inch
or less between the table or backstop and the sanding
belt or disc.-
DO NOT sand pieces of material that are too small to
be safely supported.
KEEP fingers away from where the belt goes into the
dust trap.
WHEN sanding a large workpiece, provide additional
support at table height.
DO NOT sand with the workpiece unsupported.
Support the workpiece with the backstop or table. The
only exception is curved work performed on the outer
sanding drum. Plan your work support.
NEVER USE ANOTHER PERSON as additional
support for a workpiece longer or wider than the table.
ALWAYS remove scrap pieces and other objects from
the table, backstop or belt before turning the sander
"ON."
NEVER perform layout, assembly or set-up work on the
table while the sander is operating.
NEVER use solvents to clean plastic parts. Solvents
could dissolve or other wise damage the material. Use
only a soft damp cloth to clean plastic parts.
SHOULD any part of your sander be missing, damaged,
or fai! in any way, or any electrical components fail to
perform properly, shut off switch and remove plug from
power supply outlet. Replace missing, damaged or
failed parts before resuming operation.
NEVER PULLTHE POWER CORD out of the receptacle.
Keep cords away from heat, oil and sharp edges.
HAVE AN ELECTRICIAN
REPLACE OR REPAIR
damaged or worn cords immediately.
When using the belt to grind or sharpen metal or
plastic material:
o DO NOT wet grind or polish. Never use a steady
stream of water on the workpiece. Dip or quench
the workpiece in water to cool it.
• DO NOT OVERHEAT THE WORKPIECE.
Move
metal across the abrasive and cool it when it
becomes hot.
o DO NOT grind or polish magnesium. It could
CATCH on fire.

GROUNDING
INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric
current and reduces the risk of electric shock. This tool is
equipped with an electric cord that has an equipment
grounding conductor and a grounding plug. The plug
MUST be plugged into a matching receptacle that is
properly installed and grounded in accordance with ALL
local codes and ordinances.
DO NOT MODIFYTHE PLUG PROVIDED. If it will not fit the
receptacle, have the proper receptacle installed by a
qualified electrician.
IMPROPER CONNECTION
of the equipment grounding
conductor can result in risk of electric shock. The
conductor with the green insulation (with or without yellow
stripes) is the equipment grounding conductor. If repair or
replacement of the electric cord or plug is necessary, DO
NOT connect the equipment grounding conductor to a live
terminal.
CHECK with a qualified electrician or service personnel if
you do not completely understand the grounding instructions,
or if you are not sure the tool is properly grounded.
USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE
3-PRONG GROUNDING
PLUGS AND 3-POLE
RECEPTACLES THAT ACCEPT THE TOOL'S PLUG.
REPAIR OR REPLACE DAMAGED OR WORN CORD
IMMEDIATELY.
GUIDELINES
FOR
EXTENSION
CORDS
USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The table below shows the correct size to use
depending on cord length and nameplate ampere rating. If
in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Be sure your extension cord is properly wired and in
good condition. Always replace a damaged extension cord
or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive
heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit
must not be less than #12 wire and should be protected
with a 15 Amp time lag fuse. Before connecting the motor to
the )ower line, make sure the switch is in the OFF
position and the electric current is rated the same as the
current stamped on the motor nameplate. Running at a
lower" voltage will damage the motor.
SAVE THESE
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in FIGURE A.
FIGURE A shows a 3-prong electrical plug and receptacle
that has a grounding conductor. If a properly grounded
receptacle is not available, an adapter (FIGURE B) can
be used to temporarily connect this plug to a 2-contact
ungrounded receptacle. The temporary adapter should be
used only until a properly grounded receptacle can be
installed by a qualified technician. The adapter (FIGURE B)
has a rigid lug extending from it that MUST be connected
to a permanent earth ground, such as a preperly
grounded receptacle box. The Canadian Electrical Code
prohibits the use of adapters.
CAUTION: In all cases, make certain the receptacle in
question is properly grounded. If you are not sure have a
certified electrician check the receptacle.
This belt / disc sander is for indoor use only. Do not
expose to rain or use in damp locations.
