USE INSTRUCTIONS.
Before starting up the sander, we recommend that
you carefully read all of the instructions as indicated.
Please respect all regulations regarding the
prevention of accidents, health and safety directives,
laws and applicable restrictions for work places. The
sander must only be used by persons who have been
instructed in its use and only for the purposes for
which it has been designed.
POWER SUPPLY.
Make sure the power supply is adapted to the
requirements shown on the information panel of the
sander (1). Using the motor at low voltage will make
it operate slowly. This will reduce performance and
may cause the motor to overheat.
EXTENSION CORD.
If the working area is at some distance from the power
supply, use an extension cord of enough diameter
and quality.
START-UP.
When unpacking the sander, make sure it is intact,
complete and has not been damaged in transport.
Never use a damaged sander. Before use, check that
the backing pad is correctly attached and tightened.
Connect the power cord to a grounded outlet (220–
240 VAC, 50/60 Hz). In order to get the maximum
power from this sander it is recommended to use it
with a vacuum cleaner and a net sanding disc.
OPERATION.
The sander is intended to be operated as a hand
held tool. The sander can be used in any position.
Note! The sander can develop a torque reaction
when started. Make sure the sander is switched
off. Select a suitable abrasive and secure it to the
backing pad. Make sure the abrasive is centred on
the backing pad. Switch on the sander by pressing
the ON/OFF button (2). The sander can now be
started by pressing the lever (3). The speed can be
adjusted between 4000 and max RPM by adjusting
the position of the lever. The max RPM can be
adjusted by pressing RPM + or RPM - (4). Each
press increases or reduces the speed by 1000 RPM,
until it reaches the limits. The RPM can be adjusted
in the range 4000 to 10000 RPM. When sanding,
always place the sander on the work surface before
starting. Always remove the sander from the work
surface before stopping it. This will prevent gouging
of the work surface due to excess speed of the
abrasive. Move the sander in long sweeping strokes
along the surface being sanded, letting the sander do
the work (5). Pushing down on the sander slows the
removal rate and produces an inferior quality surface
(6). Never operate with the sander inclined, this can
damage the base and break the sandpaper (7). Be
sure to check your work often. This sander is capable
of removing material rapidly, especially with coarse
paper. To produce the best finish possible, start with
coarse grit sandpaper and change gradually to finer
and finer paper. A final sanding with a piece of well-
worn fine sandpaper will produce a professional
looking finish that in many cases will need no hand
sanding at all. When sanding painted surfaces, you
may find that the sandpaper loads up and clogs with
paint. A heat gun will work much better to remove
paint before sanding. Avoid overloading the sander.
Overloading will result in a considerable reduction in
speed and efficiency and the sander will become hot.
In this event, run sander at a no-load condition for a
minute or two. When sanding is finished, turn off the
sander by pressing the ON/OFF button.
PRECAUTIONS TO TAKE WHEN SANDING PAINT.
Sanding of lead based paint is not recommended due
to the difficulty of controlling the contaminated dust.
The greatest danger of lead poisoning is to children
and pregnant women.
