SANDING DUST SAFETY WARNINGS
Some dust created by sanding, and other construction activities contains
chemicals known to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
•leadfromlead-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 exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.
SAFETY SYMBOLS
Read this instruction
booklet carefully.
Wear ear protection.
Wear eye
protection.
Wear a dust mask that is
specially designed to
filter microscopic
particles.

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved 13 amp BS 1363 plug, or a suitably fused isolator switch.
If the plug has to be changed because it is not suitable for your socket, or
because of damage, it must be removed and a replacement fitted, following
the wiring instructions shown below. The old plug must be discarded safely, as
insertion into a power socket could cause an electrical hazard.
If the colours of the wires in the power cable do not agree with the markings
on the plug.
• The BLUE wire must be
connected to the
terminal which is
marked N or coloured
black.
• The BROWN wire must
be connected to the
terminal which is
marked L or coloured
red.
AN APPROVED RESIDUAL CURRENT DEVICE (RCD) WHICH HAS A TRIPPING
CURRENT OF LESS THAN 30mA MUST BE USED.
If you are not sure, consult a qualified electrician. DO NOT try to do any repairs
This symbol indicates that this is a Class II product, and does not require

ASSEMBLY
SECURING THE SANDER TO A WORKBENCH
If sander is to be used in a permanent location, it should be fastened securely
to a workbench via the four securing holes (one on each corner).
1. Mark out the position of the holes.
2. Secure using suitable bolts, washers, and nuts (not supplied).
An alternative method is to fasten the sander to a mounting board.
The board should be sufficient size to avoid tipping while in use. Any good
grade of 3/4" plywood or chipboard will be sufficient.
The mounting board can then be clamped to a workbench when required.
DUST EXTRACTION
1. Connect a suitable dust collector
to the dust extraction port.
• The dust exhaust port has an
internal diameter of 36 mm and
an outside diameter of 39 mm.
NOTE: Even with a dust collection
system, it is necessary to
periodically clean sanding
dust from the recess in the
table. A build up of dust in the
table recess may prevent the belt or spindle from making a complete
oscillation.
WARNING: CONTACT WITH, OR INHALATION OF DUST FROM LEAD BASED
PAINTS CAN ENDANGER THE HEALTH OF THE OPERATOR AND
BYSTANDERS. ALWAYS WEAR A SUITABLE DUST MASK WHEN USING THE
SANDER.
