WHEEL DRESSING
Wheel dressing is done to renew sharpness or to true up the face of a wheel. A build up of metals and
dirt will become embedded in a wheel as it is used. Use a wheel dressing tool (not supplied) to clean
wheels on a regular basis. In doing so, it will improve the bench grinder’s performance.
NOTE: New wheels may sometimes require dressing to true up their surface.
CLEANING
Use only mild soap and a damp cloth to clean the bench grinder. Never let any liquid get inside the tool.
DO NOT immerse any part of the bench grinder into a liquid.
Service beyond recommended maintenance on this bench grinder should only be performed by an
authorized, qualified technician.
WARNING
Ensure the bench grinder is disconnected from the
power supply when performing maintenance tasks
to avoid injury.
!
n. Keep guards in place and in good working order. With the machine disconnected from the mains
supply check that the guards are secure and fitted correctly.
o. Always keep the tool rest as close to the grinding wheel as possible. The gap between the tool rest
and the grinding wheel should be no more than 3mm.
p. Do not attempt to grind objects that are too small to hold safely.
q. Do not use the work piece to slow down the grinding wheel once the machine has been switched off.
r.
WARNING! Do not use bench grinders in areas where there is a risk of explosion or fire from
combustible materials, flammable liquids, paint, varnish, petrol etc. flammable gases and dust of an
explosive nature. As a precaution it is recommended that you consult an expert on a suitable fire
extinguisher and its use. The metal particles (sparks) which are produced during grinding are hot
and could ignite any combustible material in the vicinity of the operation.
