Specific Safety Rules; Electrical; Extension Cords - KNOVA KN BD-46B Manual Del Usuario

GENERAL SAFETY RULES
• NEVER START A TOOL WHEN ANY ROTATING
COMPONENT IS IN CONTACT WITH THE WORKPIECE.
• DO NOT OPERATE A TOOL WHILE UNDER THE
INFLUENCE OF DRUGS, ALCOHOL, OR ANY
MEDICATION.
• WHEN SERVICING use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.

SPECIFIC SAFETY RULES

• FIRMLY CLAMP OR BOLT your tool to a workbench or
table at approximately hip height.
• NEVER stand or have any part of your body in line with
the path of the workpiece.
• PLAN YOUR WORK TO REDUCE THE RISK OF
THROWBACKS (when the workpiece catches the sanding
drum and is torn from your hands).
• MAKE SURE THERE'S NO DEBRIS between the
workpiece and its supports.
• WHEN SANDING IRREGULARLY SHAPES
WORKPIECES, plan your work support so it will not slip
and be pulled from your hands.
• USE EXTRA CAUTION WITH LARGE, very small or
awkward workpieces.
• NEVER USE THIS TOOL to finish pieces too small to
hold by hand.
• USE EXTRA SUPPORTS (TABLES, SAW HORSES,
BLOCKS, ETC.) for any workpieces large enough to tip
when not secured to the work surface.
• NEVER sand more than one piece at a time. DO NOT STACK
more than one workpiece on the sander table at a time.
• ALWAYS FEED WORKPIECE FROM LEFT TO RIGHT
against the direction the drum sleeve is rotating.
• DO NOT USE DRUMS, sanding sleeves or belts which
show visual signs of wear such as grooves, tears or rips.
• ALWAYS STAY ALERT! Do not allow familiarity (gained
from frequent use of your sander) to cause a careless
mistake. ALWAYS REMEMBER that a careless fraction
of a second is sufficient to inflict severe injury.

ELECTRICAL

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong grounding
plugs and 3-pole receptacles that accept the tool's plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.

• USE ONLY RECOMMENDED ACCESSORIES listed
in this manual or addendums. Use of accessories that
are not listed may cause the risk of personal injury.
Instructions for safe use of accessories are included
with the accessory.
• DOUBLE CHECK ALL SETUPS. Make sure the spindle
or sanding belt assembly is tight and not making contact
with sander or workpiece before connecting to
power supply.
• MAKE SURE THE WORK AREA HAS AMPLE LIGHTING
to see the work and that no obstructions will interfere with
safe operation BEFORE performing any work using your
tool.
• ALWAYS TURN OFF THE SANDER before disconnecting
it to avoid accidental starting when reconnecting to power
supply. NEVER leave the tool unattended while connected
to a power source.
• SUPPORT WORKPIECE with miter gauge, work rest, or
worktable.
• MAINTAIN 1/16 in. clearance between worktable and
sanding belt or disc.
• AVOID KICKBACK by sanding in accordance with
directional arrows.
• IF THE POWER SUPPLY CORD IS DAMAGED, it must
be replaced only by the manufacturer or by an authorized
service center to avoid risk.
• THIS TOOL should have the following markings:
a) Wear eye protection.
b) Support workpiece with miter gauge, backstop
(work support), or worktable.
c) Maintain 1/16 in. maximum clearance between
work table and sanding belt or disc.
d) Do not perform any operation freehand.
e) Avoid kickback by sanding in accordance with
directional arrows.
• SAVE THESE INSTRUCTIONS. Refer to them frequently
and use them to instruct others who may use this tool. If you
loan someone this tool, loan them these instructions also.
When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters "W-A" or "W" on the cord's jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING
working area. Position the cord so that it will not get
caught on lumber, tools or other obstructions while
you are working with a power tool. Failure to do so
can result in serious personal injury.
WARNING
If damaged replace immediately. Never use tool with
a damaged cord since touching the damaged area

could cause electrical shock resulting in serious injury.
