Remaining Hazards; Technical Data; Noise Emission - Jet JMG-50 Gebrauchsanleitung

Wear safety shoes; never wear
leisure shoes or sandals.
Always wear the approved working
outfit.
Use safety goggles at all times.
Use ear protection at all times.
Wear a face and dust mask when
working in a dusty environment.
Do NOT stop the abrasive wheel by
forcing the machine or by using
sideways pressure.
The material to be grinded must be
held firmly so it can not move during
the grinding operation.
Never grind pieces that are too small.
Support long work pieces with helping
roller stands.
Never place your hand near the
grinding area while machine is in
operation.
Do not perform any operation
freehand; always have the
workpiece supported by the tool
rest.
Allow the abrasive wheel to come to a
complete standstill before making
adjustments.
Do not touch the machined
workpiece until it cools or you may
be burned!
Install the machine so that there is
sufficient space for safe operation
and workpiece handling.
Keep work area well lighted.
The machine is designed to operate
in closed rooms and must be bolted
on a firm workbench or stand.
Make sure that the power cord does
not impede work and cause people to
trip.
Keep the floor around the machine

3.3 Remaining hazards

When using the machine according to
regulations some remaining hazards
may still exist
The moving abrasive wheel in the
work area can cause injury.
The moving abrasive belt in the work
area can cause injury.
Broken abrasive wheel can cause
injury.
Broken abrasive belt can cause
injury.
Thrown grinding chips, dust and
noise can be health hazards.
Be sure to wear personal protection
gear such as safety goggles, dust
mask and ear protection.
Some dust and gases created by
grinding can be heath hazards.
To reduce your risk of exposure, work

The use of incorrect mains supply or
a damaged power cord can lead to
injuries caused by electricity.
Avoid body contact with earthed or
grounded surfaces (e.g. pipes,
radiators, ranges and refrigerators).
