Workpieces with diameters below 1 3/8 in may not
be worked with the belt grinder GX75!
Special safety instructions.
Wear personal protective equipment. Depending on appli-
cation, use face shield, safety goggles or safety glasses.
Where appropriate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stopping small
abrasive or workpiece fragments.
The eye protection
must be capable of stopping flying debris generated by
various operations. The dust mask or respirator must be
capable of filtrating particles generated by your opera-
tion. Prolonged exposure to high intensity noise may
cause hearing loss.
Before switching on, make sure that all clamping levers
and tensioning devices are well tightened.
If the machine
suddenly sinks or the workpiece comes loose during the
working procedure, this can lead to serious accidents.
