Operator Safety (Cont.)
Sanding 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. All
sources of ignition should be removed entirely from the work
area.
Poorly ventilated work areas may create an explosive
environment, when some combustible materials (solvents,
thinners, alcohol, fuel, some paints, wood dust, etc) are
present in the atmosphere. 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 injury and/or death due to electrocution 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
serious injury and/or 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 serious injury and/or 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. DO NOT
close a door on cord. DO NOT pull cord around sharp edges
or corners.
DO NOT unplug by pulling on power supply cable. To unplug
grasp the plug. DO NOT handle plug or operate machine with
wet hands. DO NOT put any objects into motor openings.
Serious injury and/or death due to electrocution may occur if
the machine runs over the power supply cable and it becomes
damaged. Keep the cable away from the sanding tool. Always
keep the power supply cable raised above the machine and
sand away from the power supply cable.
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.
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.
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. Always unplug the 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.

Operator Safety (Cont.)
Never become distracted during sanding operations, check
what is happening continually. Use common
sense. DO NOT use the machine, if you are tired, have
consumed alcohol or have taken medication that
may affect your judgement or your body control.
DO NOT smoke during sanding operation.
DO NOT use this machine to sand steps and 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.
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.

Commencing Operation (Cont.)
Instructions for electrical connection (cont.)
If the machine is not connected correctly to the electricity
network, death due to electrocution may occur. To prevent
electric shocks always use a grounded three wire electrical
system. For maximum protection against electric shocks use a
circuit protected with a differential cut-out switch.
Tampering with the grounding plug in any way may result in
death from electrocution. DO NOT cut, remove or break the
grounding plug. If the socket does not match the plug consult
a qualied electrician.
Using the machine with unsuitable and/or excessively long
cables may cause injury or damage to people or objects.
Do not use the machine if the switch malfunctions.
If the machine is used with a damaged plug or power supply
cable, death may occur from electrocution. If cables or plugs
are worn or damaged in any way, have them replaced by the
manufacturer or certied machine repair center in order to
prevent risks to safety.
The machine must never be moved using its cable and the
cable must never be pulled when disconnecting from the
socket.
Keep the cable away from sources of heat, oil and sharp
edges.
Only use approved cables. The maximum recommended cable length is 10 m; for greater lengths use cables
with a larger cross-section.

Prevention Measures for Users
Removing sawdust generated during use
Personal safety measures
Sawdust can ignite spontaneously and cause injury or
damage. It must be disposed of appropriately. Always empty
the sawdust into metal containers which are located outside
the building.
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.
For minimized dust environment use a vacuum cleaner
intended for wooden dust.
Sawdust can spread through the air and be inhaled when
using the sanding machine. Always wear a dust mask of at
least class P2, when using the sanding equipment.
The eyes and/or body may suffer injury if personal safety
clothing is not used. It is adviceble to wear safety goggles,
protective clothing during sanding operations.
