Experiment Motor with Gearbox 1021806
Instruction Sheet
11/18 TB
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.
1. Safety instructions
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 re-
quirement, the appropriate warnings must be at-
tached to the experiment stand.
Proper use in compliance with directives:
The motor must be mounted on a stable surface
(stable bench, solid stand equipment or if neces-
sary a bench clamp). Use as a hand-held drill or
power screwdriver is inadmissible due to the grip
lacking the appropriate ergonomic form (ma-
chine guidelines 98/37/EC). For the sake of op-
erator safety, a protective wall is erected to ef-
fectively shield observers from any flying objects
which might be unleashed when operating the
machine at high speeds. This wall is made of
safety glass (e.g. plexiglass, polycarbonate,
etc.).
