Replace radial shaft sealing rings
If oil leaks from the rotary module, the radial shaft seal-
ing rings must be replaced immediately. If the radial
shaft sealing rings are replaced erroneously, components
may become damaged. The warranty is void. This is why
we recommend contacting SCHUNK Service and having
the radial shaft sealing rings replaced by SCHUNK.
WARNING
Risk of burns due to contact with hot surfaces and hot
oil!
Ø
Prior to starting work on the module, allow it to cool
down to no more than 40°C.

the module.

CAUTION

Hydraulic oil may cause irritation if it comes into contact
with the skin and eyes. If hydraulic oil leaks, this poses a
danger of slipping.
Ø
Avoid skin contact with hydraulic oil.
Ø
Wear protective gloves and safety goggles.

Properly remove spilled or leaking hydraulic oil im-
mediately.
