7.4.2 Basic cleaning

 DANGER

Danger to life in case of improper disassembly.

With the AS variant, the cylinder piston and the cover are under
tremendous spring force, which can eject the parts.

With the AS variant, when dismantling the chuck piston and
cover, use a device that prevents the cover and cylinder piston
from being ejected.

It is recommended to have the maintenance work and change
of seals carried out by SCHUNK.

For basic cleaning, the product must be disassembled, cleaned and
reassembled. With the "PM" variant, the pneumatic jaw end
position control must also be set.

Disassembly

Before disassembling the product, switch off the machine and
secure it against being switched on again. Then remove all
compressed air lines. No residual energy may be left in the
product.

• Pull out the plug (81).
• Unscrew the screws (84) and the fitting

screws (82) and disassemble the clamping
system from the machine table.

• If using clamping sleeves (85), remove them

from the housing.

• Remove screws (64) and take off the cover

strip (8).

• Remove screws (66) and take off the guide

strip (6).

• Variant "PM" also includes a compression

spring (27), O-ring (43), sphere (24) and O-
ring (42).
