1. Safety instructions
Risk of injury!
The experiment motor
is designed for
open experiment
setups and, naturally
for that reason,
cannot be equipped
directly with
mounted safety mechanisms
to
protect against flying parts or
with shielding for the
rotating components.
Consequently the following
safety instructions
must be read thoroughly and
strictly obeyed
while operating the motor!
Long hair, loose
clothing as well
as jewelry could
get caught in
the
rotating
parts and result in injury. To avoid this hazard
persons with long hair should wear a hair net.
Inappropriate clothing or jewelry should be re-
moved.
When working with the belt pulley (9)
and drive belts (10), an additional
danger exists, e.g..a finger could get
caught between the belt and the
pulley.
The safety instructions attached to the motor
must remain visible and should not in any way
be visibly obscured by the experiment setup.
Should it prove impossible to comply with this
requirement, the appropriate warnings must be
attached to the experiment stand.
Proper use in compliance with directives:
The motor must be mounted on a stable sur-
face (stable bench, solid stand equipment or if
necessary a bench clamp). Use as a hand-held
drill or power screwdriver is inadmissible due to
the grip lacking the appropriate ergonomic form
(machine guidelines 98/37/EC). For the sake of
operator safety, a protective wall is erected to
effectively shield observers from any flying ob-
jects which might be unleashed when operating
the machine at high speeds. This wall is made
of safety glass (e.g. plexiglass, polycarbonate,
etc.).
