Safety is a combination of common sense, staying alert and knowing how your item works.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instruc-
tions may result in electric shock, fire and serious injury. To avoid mistakes and serious injury, do not
plug in your tool until the following steps have been read and understood.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not work on floor surfaces that
are slippery with sawdust or wax.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders at a safe distance from the work area. Never allow children or pets near the tool.
ELECTRICAL SAFETY
1. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric
shock.
2. Power tool plugs must match the outlet. Never modify the plug in any way. Modified plugs with unmatching out-
lets will increase the risk of electric shock.
3. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
PERSONAL SAFETY
1. Stay alert. Watch what you are doing and use common sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
2. Use personal protective equipment. Always wear safety goggles at all times that comply with ANSI Z87.1. Use ear
protection such as plugs or muffs during extended periods of operation. Wear a face mask or dust mask to fight the
dust produced by sanding operations.
3. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when operating the tool. Inappropri-
ate clothing and items can get caught in moving parts and draw you in. Always wear non-slip footwear and tie back
long hair.
4. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool.
POWER TOOL USE AND CARE
1. Avoid accidental start-ups. Make sure the power switch is in the OFF position before connecting to power source,
picking up or carrying the tool.
GENERAL SAFETY RULES
WARNING: Dust generated from certain materials can be hazardous to
your health. Always operate the tool in a well-ventilated area and provide
for proper dust removal. Use dust collection systems whenever possible.

4
2. Check power tool for damaged parts. Check for misalignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Do not use the power tool if the switch does
not turn ON/OFF. Any part that is damaged should be properly repaired or replaced before use.
3. Do not force the tool to do a job for which it was not designed. Use the correct power tool and accessories and
follow the instructions for your application to prevent hazardous situations.
4. Remove adjustment tools. Always make sure all adjustment tools or wrenches are removed from the tool before
turning on the power tool. A key left attached to a rotating part of the power tool may result in personal injury.
5. Keep guards in place and in working order before operating the tool.
6. Use dust extraction. If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of dust collection is highly recommended to reduce dust-related haz-
ards.
7. Never leave a running tool unattended. Do not leave the tool until it has come to a complete stop.
8. Disconnect the plug from the power source. ALWAYS remove the power cord plug from the electrical outlet
when making adjustments, changing parts, or storing power tools. Such preventive safety measures reduce the risk
of starting the power tool accidentally.
9. Maintain power tools properly. Safely store power tools out of the reach of children. Always keep tools clean and
in good working order. Follow instructions for lubricating and changing accessories.
GENERAL SAFETY RULES
WARNING! EXTREME CAUTION REQUIRED WHEN SANDING PAINT. The dust residue may con-
tain LEAD which is poisonous. Exposure to even low levels of lead can cause irreversible brain and nervous system
damage, to which young and unborn children are particularly vulnerable. Any pre-1960s building may have paint
containing lead on wood or metal surfaces that has since been covered with additional layers of paint. Lead based
paints should only be removed by a professional and should not be removed using a sander. If you suspect that paint
on surfaces contains lead please seek professional advice.
WARNING! USE A FACE MASK AND DUST COLLECTION. Some wood and wood type products such as
MDF (Medium Density Fiberboard) can produce dust that can be hazardous to your health. We recommend the
use of a dust extraction system and an approved face mask with replaceable filters when using this machine.
1. Maintaining a Stable Stance
Ensure proper balance when using the tool. Do not stand on ladders and step ladders during operation. If the ma-
chine is to be used on a higher and otherwise unreachable surface, a suitable and stable platform or scaffold tower
with hand rails and kick boards should be used.
2. Preparing the Workpiece
Check the workpiece for any protruding nails, screw heads or anything else that could tear or damage the belt.
SPECIFIC RULES FOR THE SANDER

5
SPECIFIC RULES FOR THE SANDER
3. Securing the Workpiece
Never hold the workpiece in your hand or across your legs. Small workpieces must be adequately secured so that
the rotating belt doesn’t pick them up during the forward motion of the sander. Unstable support causes the belt
to bind, resulting in a loss of control and possible injury.
4. Checking the Powercord
Make sure that the power cord is prevented from coming into contact with the machine or getting caught up on
other objects preventing completion of the sanding pass.
5. Holding the Sander
Keep handles and hands dry, clean and free from oil and grease. Hold the power tool by the insulated gripping
surfaces only in case the belt contacts its own cord. Cutting a “live” wire may make exposed metal parts of the tool
“live” and could give the operator an electric shock.
6. Sand on Dry Surfaces Only
This machine is to be used for dry sanding only. Do not attempt to use for wet sanding operations, as fatal electric
shock may occur.
7. Starting the Sander
Always start the sander before the sanding belt is in contact with the workpiece. Let the sander reach full speed
before using the tool. Do not start the machine whilst it is in contact with the workpiece.
8. Sanding the Workpiece
CAUTION: when the machine contacts the workpiece it will have a tendency to grab and pull forward. Resist the
forward motion and keep the belt sander moving at an even pace. Never pull the tool backwards over the work-
piece. Sand in the direction of the grain whenever possible. Remove the sanding dust between each grade of sand-
ing sheet. Never leave the machine unattended while it is still running.
9. Setting Down the Sander
Wait for the belt to stop before setting the tool down. An exposed rotating belt may engage the surface, leading to
possible loss of control and serious injury. Always lay the sander on its side to prevent accidents if the machine is
inadvertently started.
10. Unplug Your Sander
Ensure that the sander is disconnected from the main supply before servicing, lubricating, making adjustments,
changing accessories, or replacing sanding belts. Accidental start-ups may occur if the tool is plugged in during an
accessory change. Before plugging the tool back in, check that the trigger is OFF.
11. Replacing the Sanding Belt
Replace the sanding belt as soon as it becomes worn or torn. Torn sanding belts can cause deep scratches that are
difficult to remove. Ensure that the sanding belt is the correct size for the machine. After changing a sanding belt,
rotate the belt to make sure it doesn’t hit any part of the tool.
12. Cleaning your Sander
Clean and maintain your tool periodically. When cleaning a tool, be careful not to disassemble any portion of the
tool. Internal wires may be misplaced or pinched and safety guard return springs may be improperly mounted.
Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

GUIDELINES FOR USING EXTENSION CORDS
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 result-
ing in loss of power and overheating. The table below shows the correct size to be used according to cord length
and nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier
the cord.
Make 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/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be pro-
tected with a 15 A time-delayed fuse. Before connecting the motor to the power 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.
WARNING: This tool must be grounded while in use to protect the operator from electric shock.
ELECTRICAL INFORMATION
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an 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 outlet that is
properly installed and grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a
licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conduc-
tor 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 licensed electrician or service personnel if you do not completely understand the grounding instruc-
tions or whether the tool is properly grounded.
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a li-
censed electrician check the outlet.
WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.
