1. Safety instructions 

When  carefully  assembled  and  properly  used, 
safety  of  experimenting  with  the  reversible  pen-
dulum can be guaranteed.  There is, however,  a 
possible risk of injury or damage to the pendulum 
if care is not taken. 

 

Read  this  instruction  manual  all  the  way 
through and observe it in full. 

 

Set  up  the  stand  on  solid,  level  ground  and 
fasten the assembly screws tightly. 

 

Fasten  the  securing  screw  for  the  movable 
pendulum bob tightly so that the bob cannot 
move unchecked. 

 

Use the adjustment screws in the base plate 
of the stand to align the bearing plate in such 
a way that the bearing axes of the pendulum 
bob can be even. 

 

Always handle the pendulum with both hands 
when setting it up or adjusting it. 

 

Carefully  suspend  the  pendulum  from  the 
bearing plate and check that the bearing axes 
are in the correct positions. 

 

Do  not  subject  the  pendulum  to  excessive 
pushes and do not deflect it by more than 10 
cm at the bottom end.
