Maintenance
Lubrication
To maintain the safe operation and high quality of the chuck, it
must be regularly lubricated at the lubrication nipples with LINO
MAX.
For optimum grease distribution, the clamping piston must travel
the entire clamping stroke several times after lubrication.
Lubrication
Operating conditions
Depending on the operating conditions, the function and clamping
force must be checked after a specific period of operation (see
"Maintenance intervals" chapter(ļ 9.2, Page 39)). Only use a
calibrated clamping force tester for measuring in the clamping
force test (SCHUNK SGT 270).
Technical condition
With the smallest possible actuating pressure (hydraulic cylinder),
the base jaws should move evenly. This method only provides a
limited indication and is not a substitute for measuring the
clamping force.
If the clamping force has dropped too much or if the base jaws and
piston no longer move properly, the chuck has to be disassembled,
cleaned, and relubricated.
Only use original SCHUNK spare parts when replacing damaged
parts.
