1. Safety
1.1 General safety instructions for your safety and
the safety of others
1. Keep theworking area tidy. Cluttered surfaces and benches invite accidents.
2. Do not use themachine in dangerous environments. The machine should not
be used on moist or wet surfaces or in rain. Make sure that thework area is well
lit. When working in dusty atmospheres, make sure that theair is adequately
circulated. Do not operate power tools in explosive atmospheres, such as in
thepresence of flammable liquids, gases or dust.
3. Avoid electric shocks. Avoid body contact with earthed or grounded surfaces such
as pipes, radiators, ranges and refrigerators when using power tools.
4. Keep children and bystanders away. Keep children and visitors at asafe distance
from electrical machinery/tools and electric cables in theworkplace.
5. Store power tools out of thereach of children. When not in use, power tools
should be stored locked away in asafe place, away from children.
6. Do not force themachine. The correct feed rate makes thework better and safer.
7. Use thecorrect tool for thejob. Do not force atool to perform atask that it was
not designed for.
8. Wear suitable attire. Do not wear any loose-fitting clothing, gloves, necklaces,
bracelets or other jewellery that can get caught in moving parts. Non-slip footwear
is recommended. Wear ahairnet or similar if you have long hair.
9. Always wear safety glasses. Normal glasses are not tough enough to withstand
impacts. Use adust mask or dust filter when working in dusty environments.
10. Connect dust extraction equipment. If themachine is equipped with dust
extraction equipment, ensure that it is connected and used properly. Make sure
to empty thedust bag regularly.
11. Do not abuse themains lead. Do not carry themachine by its mains lead. Do not use
themains lead to pull or unplug thepower tool, pull theplug out instead. Make sure
that themains lead does not come into contact with heat, oil, or sharp edges.
12. Secure theworkpiece firmly. Where possible, use clamps or avice. You can then
operate thetool using two hands. This is much safer than holding theworkpiece in
one hand.
13. Do not overreach. Make sure that you stand steady and balanced all times.
14. Look after you tools. Keep blades sharp and clean for thebest and safest performance.
15. Follow themanuals recommendations regarding lubrication and replacement of
accessories. If it is damaged it should be replaced by aqualified service technician.
Inspect all leads and cables regularly to check for any damage. Make sure that
themachine’s handles and controls are clean, dry and free from oil and grease.
16. Turn thepower off. Pull out theplug and push in theemergency stop button before
servicing or changing any blades, drill bits, cutters or sanding discs.
17. Remove all spanners and repair tools. Make ahabit of checking to make sure that
themachine is free of all spanners and tools before turning thepower on.

18. Avoid accidental starts. Do not walk around with your finger on thetrigger of apower
tool if it is plugged in. Make sure that thepower switch is set to [0] before plugging
in any power tool.
19. Use thecorrect extension leads. If you use extension leads outdoors, only use
those designed for outdoor use. Only use extension leads with adequate wire core
area and roll out thewhole lead.
20. Use common sense and be careful. Think carefully before carrying out every
action, so that it is carried out safely. Never operate machines/power tools when
you are tired or under theinfluence of medicine.
21. Inspect thetool for damage. Before starting thetool, make sure that theguards
and other parts are undamaged and working properly, that moving parts can rotate
freely and are correctly aligned, that no moving parts can get caught and that there
is no fault or defect that could affect theperformance of themachine. A safety guard
or any other part that is damaged should be repaired by atradesman or replaced.
Damaged power leads and switches must always be replaced by atradesman.
Never operate atool if you cannot stop or start thetool comfortably.
22. Use only recommended accessories. The use of non-recommended accessories
can cause accidents and personal injury.
23. Should only be repaired by aqualified technician. This tool conforms to current
safety requirements. Repairs to thetool should only be carried out by atradesman
using original spares; otherwise thetool could cause accidents and personal injury.
24. Use aResidual Current Device on all 230 V power tools. This can help minimise
therisk of anelectric shock if anearth fault or short circuit occurs. The product
must not be modified or used for any other purpose than that for which it has been
designed. Regularly check that all screws and nuts are securely tightened.
1.2 Specic safety regulations for bench sanders
• Place themachine on astable, level surface with plenty of room for manoeuvre.
• Think about how you are going to hold theworkpiece during theentire sanding
operation. Be wary of kickbacks and injuries. The workpiece could catch in
thesanding belt or disc and be ripped from your grasp.
• When using thesanding disc, always hold theworkpiece against theside of
thedisc moving downwards towards thetable. If you sand against theupward
side theworkpiece can easily be ripped from your grasp.
• The distance between thebelt/disc and work rest must never exceed 2 mm.
• To prevent therisk of fire; keep themachine free of sander dust. Sparks produced
when sanding metal can start fires. Prevent this by:
- Disconnecting any dust extractor suction hose that might be attached.
- First blowing off any dust particles on or in themachine.
- Removing any particles of metal before sanding wood again.
• Using thesander in adry place, indoors and out of therain. Make sure that
thework area is well illuminated.
• Position thesander in such away neither theuser nor any observer need stand in
line with thesanding belt or disc.
• Remove everything from theside table except theworkpiece and themitre guide.

• Avoid placing your hands in such away that anaccidental slip might cause afinger
or hand to come into contact with theabrasive surface. Keep your fingers well away
from theopening to thedust extractor.
• Keep your face and as much of your body as possible out of range of possible
kickbacks.
