accidents while using pedestal grinders. Pedestal grinders
can be extremely dangerous if not used properly! Only those
who have been formally trained should operate a pedestal
grinder. The following safety rules must be observed when
operating a pedestal grinder. |

Safety before working on a pedestal
grinder |
- Fasten pedestal and bench grinders on
a solid surface securely.
- Ensure all the guards are in place
and secure before using a grinder.
- Adjust tool rests to within 3 mm of
wheels.
- Never adjust rests while wheels are
moving.
- Work rest height should be on
horizontal centre line of the machine spindle.
- Check that wheels have blotters on
each side.
- Check the wheel fits properly to the
spindle when mounting. If it is loose, get another
wheel.
- Tighten the nuts before you turn the
grinder on.
- Before you switch on the grinder,
manually spin the wheel to make sure it is spinning
freely
- Visually check wheel for cracks and
damage

Safety while working on a pedestal
grinder |
- Stand to one side of the grinder
until the wheel reaches operating speed.
- Bring work into contact with the
grinding wheel slowly and smoothly, without bumping.
- Apply gradual pressure to allow the
wheel to warm up evenly.
- Use only the pressure required to
complete a job.
- Move the work back and forth across
the face of the wheel. This movement prevents grooves
from forming.
- Only grind on the front of the wheel,
not the side.
- Wheels are made only for grinding
certain items.
- Do not grind rough forgings on a
small precision grinding wheel.
- Support dressing tool so you can
apply leverage without undue effort
- Dress wheels regularly. Do frequent,
light dressings rather than one heavy dressings.
- Support dressing tools so you can
apply leverage without undue effort. With revolving
cutter dressing tools use the lugs as anchors.
- Replace worn wheels if you cannot
dress it.
