Operator Safety (Cont.)
Sanding/nishing wood oors can create an environment that
can be explosive.
The following safety procedures must be adhered to:
• Cigarette lighters, pilot lights, and any other sources
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
(solvents, thinners, alcohol, fuels, certain nishes, wood
dust, etc) are in the atmosphere. Floor sanding machines
can cause ammable material and vapors to ignite. Read
the manufacturer’s label on all chemicals being used to
determine combustibility. Keep the work area well ventilated.
• Hitting a nail while sanding can cause sparks and create
an explosion or re. Always use a hammer and punch to
countersink all nails before sanding oors.
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, 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 machine from all power.
Electrocution could occur if the machine is used on an
ungrounded electrical circuit. Never remove or disable the
grounding supply conductor on the electrical cord.
Consult an electrician if the grounding conductor is missing or
if you suspect your circuit is not grounded properly.
Use of this machine with a damaged power cord or plug could
result in an electric shock. DO NOT pull or carry by cord, use
power cord as a handle, close a door on cord, or pull cord
around sharp edges or corners.
DO NOT unplug by pulling on cord. To unplug, grasp the plug,
not the power cord. DO NOT handle plug or operate machine
with wet hands. DO NOT put any objects into motor openings.
Electrocution or injury could occur if the power cord is run over
and damaged by the sanding machines. Keep the cord away
from contact with the sanding heads. Always lift the cord over
the machine and sand away from the cord.
Moving parts on this machine can cause serious injury and or
damage. Keep hands, feet, hair, and loose clothing away from
all moving parts of the unit.
Operating the machine without all guards, doors, or covers in
place can cause an injury or damage.
DO NOT pass with the machine on objects that are hot,
burning or smoking, such as cigarettes, matches or cinders.

Operator Safety (Cont.)
Injury to the operator or
bystanders could occur if the
machine is plugged in while
performing maintenance,
servicing, changing lter, or
inspecting. Always unplug
machine when not in use.
DO NOT use solvents or other
ammable products to clean
this machine.
Dry use only. DO NOT use for
liquid recovery, which could
result in motor failure, electric
shock, and electrocution.
Airborne sanding dust should not be breathed in while operating a sanding
machine. Always wear an approved particulate respirator while operating
sanding equipment.
Injury to the eyes and or body can occur if protective clothing and or
equipment is not worn while sanding. Always wear hearing protection, and a
dust mask while sanding.
Exposure to high noise levels can cause hearing loss or impairment. Wear
EN-ISO approved hearing protection (earmuffs) when using this equipment.
Bodily injury could occur if power is supplied to the machine with the power
switch already in the “ON” position. Always check to assure the power
switch is “OFF” before connecting the machine to its power source.
DO NOT use this machine to sand steps or furniture. DO NOT ride on this
machine.
DO NOT put any objects into openings. DO NOT use with blocked openings.
Keep free from dust, lint, hair or anything that may reduce airow.
Storage
It is advisable to store the machine in its original
packaging. Doing so makes it possible to form a
column of two packages maximum, with one on
top of the other.
If the machine is removed from the original
packaging and is not used for some time ensure
the wheels and drum are not in contact with
the ground. In this case use two supports at
least 50mm in height to rest the machine on,
ensuring contact is with the base frame.
This equipment is for dry use only and must not be used
or kept outside in wet conditions. Store the machine in a
dry building, otherwise the machine could be damaged.
Storage temperature from -20°C to 50°C.

Prevention Measures for Users
Removing sawdust generated during use
Personal safety measures
Compliance with safety measures and warnings
Sawdust can ignite spontaneously and cause injury or
damage. Empty the contents of the dust bag when it is 1/3 full.
Empty the dust bag at the end of each machine use. Never
leave the dust bag unattended when it contains sawdust.
DO NOT empty the contents of the dust bag above a re.
Sawdust can spread through the air and be inhaled when
using the sander. Always wear a dust mask when using the
sanding equipment.
The eyes and/or body may suffer injury if personal safety
clothing is not used. Always wear safety goggles, protective
clothing and a dust mask during sanding operations.
Lengthy exposure to noise levels during sanding operations
may damage the hearing. Always use ear protectors during
sanding operations.
Never become distracted during sanding operations, check
what is happening continually. Use common sense. DO NOT
use the machine when tired.
Using the machine when not fully assembled may cause injury or damage to people or objects.
DO NOT use the machine when it is not fully assembled. Keep all ttings tightly closed. Maintain

Prevention Measures for Users (Cont.)
Compliance with safety measures and warnings (cont.)
Using the machine without the safety guards and covers in
position may cause injury or damage. Always ensure that all
safety guards and covers are in position and secured well.
The sanding machine may create an explosive environment.
Cigarettes, cigars, pipes, lighters, pilot ames, or any other
source of re may create an explosion if lit during sanding
operations. No sources of re should be kept near the work
area.
Poorly ventilated work areas may create an explosive
environment when some combustible materials are present
in the atmosphere, such as solvents, thinners, alcohol, fuel,
some paints, wood dust or other combustible materials. Floor
sanding may cause various materials and fumes to ignite.
Read the manufacturer’s instructions for each chemical
product used and establish its combustibility. Always keep
the work area well-ventilated.
Striking nails when sanding may generate an explosion or re.
Always ensure all nails are sunk before sanding surfaces.
Serious damage may occur if the power supply circuit trips
repeatedly or is undersized. Have the fuses, safety circuit and
power supply line checked by an authorized electrician.
Performing maintenance and/or repairing the machine when
it is not fully disconnected from the power supply may cause
death due to electrocution. Disconnect the power supply
before carrying out any maintenance and/or repair work.
The use of this machine on a circuit which is not grounded
may cause death due to electrocution. Never disconnect or
disable the grounding conductor. Consult an electrician if the
ground conductor is missing or it is suspected that the circuit
is not suitably grounded.
The use of this machine with a damaged power supply cable
may cause electric shock. Check the power supply cable
regularly for damage such as splitting or wear and tear. DO
NOT use the machine if the power supply cable is damaged.
DO NOT use the electric cable to move the machine.
Injury or damage may occur if the machine runs over the
power supply cable and it becomes damaged. Keep the cable
away from the lower part of the machine to avoid contact
with the abrasive. Always keep the power supply cable raised
above the machine.
The moving parts on this machine may cause serious injury
and/or damage. Keep hands, feet and loose clothing away
from all moving parts of the machine.
Performing maintenance or replacing the dust bag may cause
injury to the operator or people nearby if the machine is
connected to the power supply.
