WARNING! Before each use
rotate the grinding wheel by hand to check it is undamaged and secure.
Remove adjusting keys and wrenches before turning the machine on.
Ensure you wear approved safety goggles, gloves, ear
defenders and, if the machine generates dust, respiratory protection.
WARNING! Avoid subjecting machine/wheel
to excessive strain or harsh impact.
DO NOT
force the workpiece against the wheel
.
Failure to comply with this instruction may cause the wheel to break resulting in
severe personal injury.
WARNING! DO NOT
switch the machine on whilst the workpiece is in contact with the wheel
.
Keep all guards and holding screws in
place, tight and in good working order. A guard, or other part, that is damaged should be replaced to ensure that it will operate
properly and perform its intended function,
before
the machine is used. The safety guard is mandatory when the machine is used in
premises covered by the Health & Safety at Work Act.
4.2.
GRINDING
4.2.1. All grinding should be done slowly, maintaining a controlled progression
.
Rather than attempting to grind the workpiece in one go,
complete the task in even, controlled stages. Never force the workpiece into the grinding wheel and remember that metals being
ground will increase in temperature quickly.
DO NOT
touch the workpiece close to the cut as it may be very sharp.
S
erious personal injury may result if the above advice is not followed.
