Sanding/finishing wood floors can create an environment that can be explosive. The following safety proce-
dures must be adhered to:
Cigarette lighters, pilot lights and any other source of ignition can create an explosion when active during a
sanding session.All sources of ignition should be extinguished or removed entirely if possible from the
work area.
Work areas that are poorly ventilated can create an explosive environment when certain combustible
materials are in the atmosphere, i.e., solvents, thinners, alcohol, fuels, certain finishes, wood dust and
other combustible materials. Floor sanding machines can cause flammable material and vapors to burn.
Read the manufacturer’s label on all chemicals used to determine combustibility. Keep the work area well
ventilated.
Spontaneous combustion or an explosion can occur when working with sanding dust. The sanding dust
can ignite and cause injury or damage. Sanding dust should be disposed of properly. Always empty the
sanding dust into a metal container that is located outside of any building(s).
Hitting a nail while sanding can cause sparks and create an explosion or fire. Always
use a hammer and punch to countersink all nails before sanding floors.
Operating a machine that is not completely or fully assembled could result in injury or property damage. Do
not operate this machine until it is completely assembled. Keep all fasteners tight. Keep adjustments
according to machine specifications

DANGER:
DANGER:
Electrocution could occur if the machine is used on a power circuit that repeatedly trips or is undersized.
Have a licensed electrician check the fuse, circuit breaker or power supply
Electrocution could occur if maintenance and repairs are performed on a unit that is not properly disconnected
from the power source. Disconnect the power supply before attempting any maintenance or service.
This tool has not been waterproofed; so do not use water on work piece surface or operate in water.
Use of this machine with a damaged power cord could result in an electrical shock. Do not use the machine
if the power cord is damaged. Do not use the electrical cord to move the machine. Hold tool by insulated
gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
Electrocution or injury could occur if the power cord is run over or damaged by the sander. Keep the cord free
from under the machine to avoid contact with the sandpaper. Always lift the power cord over the machine.
Moving parts of this machine can cause serious injury and/or damage. Keep hands, feet, and loose clothing
away from all moving parts of the sander. Disconnect machine from the power source before changing the
abrasive or performing any maintenance. Do not operate unless all covers and guards are in place.
Never leave machine unattended while motor is running or connected to power source.

Failure to read and observe all safety statements found on your machine or in this Owner’s Manual can result in
serious injury or damage. Read and observe all safety statements. Make sure that all labels, decals, warnings,
cautions, and instructions are fastened to the machine. Get new labels from your authorized US Sander distributor.
Sanding dust can be airborne and can be breathed in while operating a sander. Always wear a dust mask while
operatingsanding equipment.Somedust createdbypower sandingandother constructionactivitiescontains chemi-
cals known ( to the state of California) to cause cancer, birth defects, or other reproductive harm. Some examples of
these chemicals are:
Lead from lead based paints, Crystalline silica from bricks and cement and other masonry products, and
Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposureto thesechemicals;work inawell ventilatedarea,and workwithapproved safety equipment,such as those
dust masks that are specially designed to filter out microscopic particles.
Injury to the eyes and/or body can occur if protective clothing and/or equipment is not worn while sanding. Always
wear safety goggles, protective clothing, and a dust mask while performing any sanding operation.
Bodily injury could occur if power is applied to the machine with the power switch already in the “ON’ position.
Always check to assure that the power switch is in the “OFF” position before applying power to the power cable.
Any alterations or modifications of this machine could result in damage to the machine or injury to the operator or other
bystanders.Alterations or modifications not authorized by the manufacturer voids any and all warranties and liabilities.
Accessories must be rated at least 30% more than the speed recommended on the tool warning label. Wheels and
other accessories running over the rated speed can fly apart and cause injury
Check the backing pad carefully for cracks, damage, or deformity before operation. Replace cracked damaged or
deformed pad immediately. Damaged rotating parts can fly off and cause injury to you or other persons.
Servicing of this unit must always be referred to an authorized US Sander distribu-
tor.
Pay attention that the wheel continues to rotate after the tool is switched off.

Do not leave tool running. Operate the tool only when hand-held
WARNING: Use of this machine to climb on could result in injury or damage. Do not use this machine as a step or furniture.
Serious damage to the floor can occur if the machine is left running in one spot while the sanding disc is in contact
with the floor. To avoid damage to the floor, do not dwell while lowering or raising the sanding disc. Always sand
with a constant motion and pressure.
Do not rest machine on sanding disc. To do so may cause a flat spot and reduce the quality of performance. Tip
machine back or rest on side when not in use.
Do not sand metal surfaces. Watch out for flying sparks. Hold the tool so any sparks or debris will fly away from
you and other persons or flammable materials.
Damage could occur to the machine if not properly kept in a dry building for storage. Store the machine in a dry
building.
Keep hands away from rotating parts. Use the grips provided. Hold the tool firmly.

SANDINGCUTSANDSANDPAPER
Initial Cut
The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. A coarse
abrasive should be used.
If glazing, loading, or burning takes place immediately into an initial cut, select a
coarser abrasive. If this should occur during an initial cut, the abrasive has dulled and must be replaced.
Final Cuts
The purpose of a finishing cut is to remove the scratches produced during the initial cut. Use a fine (60 -80
grit) grain abrasive.If the surface remains rough after a finishing cut, it may be necessary to use an even
finer grain of abrasive (80 -100 grit). Care should be taken in selecting the grit size of the abrasive. A very
fine grain will close the pores on a wood floor making admission of a stain difficult.
For removing gross imperfections and restore evenness to
old flooring. To remove build-up of paints and varnishes.
For first sanding of new flooring (maple, oak).
For removing minor imperfections and finishes from old flooring

OPERATINGINSTRUCTIONS
!
1. Move machine to the location of your work. Set any exposed nails with hammer and punch to avoid encounter with abrasive.
Bodily injury could occur if power is applied to the machine with the power switch already in the “ON” position. Always check to assure
that the power switch is in the “OFF” position before applying power to the power cable.
WARNING
2. Make sure the control switch is in the “Off’ position then connect the supply cable to an appropriately grounded fused circuit.
3. With the machine in the reclined position firmly grasp both handles and pull the control switch to the “ON” position.
4. Gradually lower pad to surface intended for sanding. Make sure the machine is in motion while the pad is engaged with the surface to be
sanded. You may use broad circular motion as you sand along the length of the surface or your may use a combination of forward and sideward
motions. In time you will develop your own technique to optimize coverage. It is advisable to not add effort to the pad as this may lead to “nosing
in” or “tipping” which produces grooves or lines on the surface.
5. When replacing abrasive or sanding operation is completed, return machine to reclined position, release the control switch to “Off” then
disconnect the motor pigtail from the supply cable.
DANGER:
Failure to disconnect the supply cable from machine whenever servicing, or replacing abrasive could result in electrocution or severe injury.
Never leave machine unattended while the supply cable is connected.
