Safety Tips For Grinders - Deprag GDS027-320BY Operating Instruction Booklet

1.2. Safety Tips for Grinders

· Use only approved grinding inserts with a correct shaft diameter.
· Make sure the rated speed of the insert is higher than the speed
of the grinding resp. milling machine.
· Never use a grinding resp. milling machine that is not in good
working order or one with defective parts.
· The grinding inserts (wheels/disks) must be handled and stored with care
and in accordance with manufacturers instructions.
· Check the grinding inserts (wheels/disks) for damages prior to the use in
grinding resp. milling machines. Never use damaged grinding inserts
(wheels/disks). Only use the grinding inserts (wheels/disks) in accordance
with the manufacturers' instructions.
· In case of a power interruption, the machine must be disconnected from
the air supply.
· When connecting/disconnecting the grinding resp. milling machine to/from
the air supply - please pay careful attention NOT to actuate the start lever
while doing so.
· Disconnect machine from air supply prior to changing grinding inserts.
· Never remove protective devices from machines where fitted and ensure
they are in good condition and properly adjusted before starting the
machine.
· Guards where provided should be adjusted to deflect sparks and debris
away from the operator.
· Strong vibrations may occur because of loose or damaged grinding
inserts.
· Do not use cut-off wheels (when using machines with a collet).
· Do not exceed the maximum allowable operating speed. Check the
maximum operating speed regularly.
· Check the grinding inserts (wheels/disks) for correct and tight clamping,
prior to start-up of operation. Test the grinding resp. milling machine
without load in a safe position and environment for a trial period of some
30 sec. When feeling considerable vibrations or in any other case of
irregular behaviour or operation switch off the machine immediately.
Analyze and eliminate all causes of irregular behaviour and vibration prior
to new start-up.
· When working with specific materials, dust and abrasion as well as steam
outs can be created which could result in an explosive endangered
environment.
· Make sure to sufficiently fasten the work piece(s) prior to grinding/milling.
· Do not use the machine close to inflammable liquids or gas.
