2 Notes on safety
Useful load falling from piston rod!
With a vertical mounting orientation of the cylinder, a load suspended on the
piston rod can fall when the compressed air supply is switched off.
Remove and secure suspended loads from the piston rod before you switch
u
off the compressed air supply.
Mechanical loads!
The cylinder or cylinder parts can be damaged if the scrapers are exchanged
improperly.
Make sure that the cylinder is not damaged by falling parts or incorrect tool
u
usage. Especially avoid damage to the piston rod and seals.
