chipped or worn could shatter causing in-
jury to the operator and bystanders and
damage to the machine.
4. Do not use grinding wheels that are larger
than specified, only use grinding wheels
that are rated for the machine. The rota-
tional speed shown on the grinding wheel
should always be HIGHER than the rota-
tional speed of the machine.
5. Use only grinding wheels that are recom-
mended by the manufacturer. Always fit
the blotter or paper washers on either side
of the grinding wheel.
6. When fitting a new wheel ensure blotters
are in place, fit concave side of washers
to face the wheel and tighten the lock nut
firmly.
7. Do not over tighten (over tightening can
crack a grinding wheel).
8. Do not attempt to modify the machine or
its accessories in any way.
9. Do not use excessive force on the grinding
wheel.
10. Only use gradual pressure as this will re-
duce the wear on the bench grinder and
grinding wheels and increase its efficiency
and operating life.
11. Use approved safety glasses or goggles,
face mask and if being used for an ex-
tended period wear ear defenders.
12. Do not start the machine with the work
piece in contact with the grinding wheel
or before checking the position of the tool
rest.
13. Never apply the work piece to the side of
the grinding wheel, this could cause the
grinding wheel to shatter.
14. Keep guards in place and in good working
order.
15. With the machine disconnected from the
mains supply check that the guards are
secure and fitted correctly.
16. Always keep the tool rest as close to the
grinding wheel as possible. The gap be-
tween the work rest and the grinding
wheel should be no more than 2 mm.
17. Do not attempt to grind objects that are
too small to hold safely.

18. Do not use the work piece to slow down
the grinding wheel once the machine has
been switched off.
19. Warning! Do not use Bench Grinders in
areas where there is a risk of explosion
or fire from combustible materials, flam-
mable liquids, paint, varnish, petrol etc.
flammable gases and dust of an explosive
nature.
20. As a precaution it is recommended that
you consult an expert on a suitable fire ex-
tinguisher and its use. The metal particles
(sparks) which are produced during grind-
ing are hot and could ignite any combusti-
ble material in the vicinity of the operation.
21. In case of any malfunction during the op-
eration, switch off and unplug the tool im-
mediately.
22. In case of a blockage, make sure to put
on protecting gloves before clearing
the blockage or dismounting the tool for
the clearance (see "Replacing grinding
wheel").
23. Only use accessories with a diameter ac-
cording to the relevant marking.
24. Always use the tool with accessories on
both spindles in order to limit the risk of
contact with the rotating spindle.
25. Always use the guard, work rest, transpar-
ent screen and spark arrestor as required
for the accessory(ies).
26. Replace damaged or deeply grooved
wheels.
27. Replace used wheels, if the required max.
gap size cannot be ensured anymore.
28. Adjust the spark arrestor and the work
rest frequently so as to compensate for
wear of the wheel.
