g. The dust produced when sanding lead-based paints is particularly hazardous to children,
pregnant women, and people with high blood pressure. DO NOT allow these people near
to the work area, even if wearing appropriate personal protective equipment
h. Whenever possible, use a vacuum dust extraction system to control dust and waste
i. Be especially careful when using a machine for both wood and metal sanding. Sparks from
metal can easily ignite wood dust. ALWAYS clean your machine thoroughly to reduce the
risk of fire
j. Empty the dust bag or container (where applicable) frequently during use, before taking
breaks and after completion of sanding. Dust may be an explosion hazard. DO NOT throw
sanding dust into an open fire. Spontaneous combustion may occur when oil or water
particles come into contact with dust particles. Dispose of waste materials carefully and in
accordance with local laws and regulations.
GB
k. Work surfaces and sandpaper can become very hot during use. If there is evidence of
burning (smoke or ash), from the work surface, stop and allow the material to cool. DO
NOT touch work surface or sandpaper until they have had time to cool
l. DO NOT touch the moving sandpaper
m. ALWAYS switch off before you put the sander down
n. DO NOT use for wet sanding. Liquids entering the motor housing can cause severe electric
shocks
o. ALWAYS unplug the sander from the mains power supply before changing or replacing
sandpaper
p. Even when this tool is used as prescribed it is not possible to eliminate all residual risk
factors. If you are in any doubt as to safe use of this tool, do not use it

Unpacking Your Tool

• Carefully unpack and inspect your new tool. Familiarise yourself with all its features and
functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.
Selecting the right grade of sanding sheet
• Sanding sheets are available in a variety of different grades: coarse (60 grit), medium (120
grit) and fine (240 grit)
• Use a coarse grit to sand down rough finishes, medium grit to smooth the work, and fine
grit to finish off
• Always use good quality sanding sheets to maximise the quality of the finished task
• It is advisable to do a trial run on a scrap piece of material to determine the optimum
grades of sandpaper for a particular job. If there are still marks on your work after sanding,
try either going back to a coarser grade and sanding the marks out before recommencing
with the original choice of grit, or try using a new piece of sandpaper to eliminate the
unwanted marks before going on to a finer grit and finishing the job
Fitting a sanding sheet
Note: Do not continue to use worn, torn or heavily clogged sanding sheets. Ensure foreign
objects, such as nails and screws, are removed from the workpiece before starting to sand.
WARNING: Do not use a sanding sheet on wood that has previously been used on metal.
This may cause scouring on the wooden surface.
1. Remove any dust or debris from the Sanding Base (8), before fitting a sanding sheet
2. Match the holes in a suitable sheet with the holes in the base (Image A)
3. Simply press the sheet to the base to attach it
4. To remove the sheet, peel it away from the base
Note: To maximise the life of the hook and loop base, peel the sanding sheet off slowly rather
than rapidly removing it to avoid damage to the hook and loop system.
WARNING: Take care to regularly clean out the build-up of dust on the base underneath the
sanding sheet and not to let the sheet wear completely down before replacing it. Failure to
observe these two precautionary measures can lead to damage to the hooks and loops on
the base, and the sanding sheet will not attach properly.
WARNING: Never use the sander unless the entire base is covered by the sanding sheet.
Adjusting the auxiliary handle
• This sander features two handles: the Main Handle (5) with rubber grip and the Auxiliary
Handle (1). The latter can be adjusted to suit the operator's needs
1. To adjust the Auxiliary Handle, loosen the Auxiliary Handle Locking Knob (9) until you are
able to move the handle easily into the desired position, (Image B)
2. Re-tighten the Auxiliary Handle Locking Knob, (Image C)
WARNING: Always use both handles when operating this sander. NEVER use the machine
when the Auxiliary Handle is not properly adjusted and securely fastened.
Changing the base
WARNING: Always ensure that the tool is switched off and disconnected from the power
supply, before making any adjustments or carrying out maintenance procedures.
• This sander is supplied with two interchangeable bases: a 150mm Sanding Base (8)
fitted to the tool on purchase, and a 125mm Sanding Base (10) which is supplied as an
accessory
• To change Sanding Bases:
1. Turn the sander upside down and remove the four hex screws using the supplied hex key,
(Image D). Take off the base assembly
2. Place the replacement base assembly on the tool and secure it with the four hex screws,
using the hex key
