Instructions for electrical connection
HAZARD
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 the K&T technical support service or similarly qualified
person, in order to prevent risks to safety.
Cables, extensions and plugs
Only use approved cables. The maximum recommended cable length is 7m; for greater lengths use cables with a
larger cross-section.
CAUTION
Using the machine with unsuitable cable cross-sections and/or excessively long cables
may cause injury or damage to people or objects.
WARNING
The machine must never be moved using its cable and the cable must never be pulled
when disconnecting from the socket.
WARNING
Keep the cable away from sources of heat, oil and sharp edges.
CAUTION
MACHINE WITH 230V50Hz SINGLE PHASE MOTOR
For machines with a 230-240V~50Hz single phase motor (Europe), a HO5VV-3x1.5 mm2HAR-approved
power supply cable must be used along with an approved SCHUKO 2P+T16A 200÷250V plug.
For non-European versions contact an authorised K&T distributor.

SCORPION DCS QX45 User Manual_January 2014 Edition
Recommendations on prevention measures for users
Personal safety measures
WARNING
Sawdust can spread through the air and be inhaled when using the sander. Always
wear a dust mask when using the sanding equipment.
WARNING
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.
WARNING
Lengthy exposure to noise levels during sanding operations may damage the hearing.
Always use ear protectors during sanding operations.
CAUTION
Never become distracted during sanding operations, check what is happening
continually. Use common sense. Do not use the machine when tired.
Compliance with safety measures and warnings
HAZARD
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 fittings tightly
closed. Maintain machine settings in accordance with the specifications.
HAZARD
Using the sander 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.
HAZARD
The wood flooring sander may create an explosive environment. Cigarettes, cigars,
pipes, lighters, pilot flames, or any other source of fire may create an explosion if lit
during sanding operations. No sources of fire must be kept near the work area.
HAZARD
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
machines 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.
HAZARD
Striking nails when sanding may generate an explosion or fire. Always ensure all nails
are sunk before sanding surfaces.
HAZARD
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 authorised
electrician.
HAZARD
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.
HAZARD
The use of this machine on a circuit which is not earthed may cause death due to
electrocution. Never disconnect or disable the earthing conductor. Consult an
electrician if the earth conductor is missing or it is suspected that the circuit is not
suitably earthed.

Abrasive assembly procedures
SCORPION DCS QX45 Expansion (centrifugal drum)
Fit the abrasive disc to the drum ensuring that the abrasive
protrudes approximately 1.5 mm from the drum itself.
.
CAUTION
Do not start the machine without the
abrasive inserted,
otherwise the drum will be damaged and
must be replaced.
WARNING
The abrasive is in the correct position when it protrudes approximately 1.5 mm
from the sander drum.
HAZARD
Using a damaged abrasive which could then tear while sanding may damage the
machine or floor.
SCORPION DCS QX45 EasyFit (with bubble mat surface)
Loosen the paper press screws on the drum with the correct screwdriver, being careful not to remove the
screws and paper press from the drum.
Insert one end of the abrasive under the paper press. Turn the drum so the abrasive winds around the drum itself.
Insert the other end of the abrasive under the paper press. Centre the abrasive on the drum and smooth out any
creases. Tighten the paper press screws carefully. If unsure loosen the paper press screws and repeat the
procedure.
HAZARD
An abrasive which is not stretched correctly or is damaged could tear while
sanding and damage the machine or floor.
