Spare parts
Use of unauthorized spare parts
Using unauthorized spare parts can endanger personnel and
damage the product or cause it to malfunction.
• Use only original spare parts or spares authorized by SCHUNK.
Use of special chuck jaws
Requirements of the chuck jaws
When using special chuck jaws, please observe the following rules:
• The chuck jaws should be designed to be as low as possible.
The clamping point must be as close as possible to the housing.
(clamping points at a greater distance cause higher surface
pressures in the jaw guidance and can significantly reduce the
clamping force.)
• Do not use welded jaws.
• Reduce operating pressure for higher clamping points.
Environmental and operating conditions
Required ambient conditions and operating conditions
Incorrect ambient and operating conditions can make the product
unsafe, leading to the risk of serious injuries, considerable material
damage and/or a significant reduction to the product's life span.
• Make sure that the product is used only in the context of its
defined application parameters, (3, Page 16).
• Make sure that the product is a sufficient size for the
application.
• Ensure that maintenance and lubrication intervals are
observed, (8, Page 26).
• Ensure that the environment is free from ferromagnetic
particles or chips.

Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted.
Limit/prevent accidental access for people in this area due
through technical safety measures. The protective cover and
protective fence must be rigid enough to withstand the
maximum possible movement energy. EMERGENCY STOP
switches must be easily and quickly accessible. Before starting
up the machine or automated system, check that the
EMERGENCY STOP system is working. Prevent operation of the
machine if this protective equipment does not function
correctly.

Assembly
The numbers shown for individual components refer to the
assembly illustrations or clamping block connections and to the
"Drawings" chapter. (10, Page 46)
WARNING
Risk of injury due to accidental actuation of the clamping force
block during assembly and connection.
• Make sure the power supply for the clamping block is off
during assembly and connection.
• Perform maintenance, modifications, or installations outside
of the danger zone.
WARNING
Risk of injury from clamping block or chuck jaws falling during
transport, installation or removal!
• Make sure the clamping block and chuck jaws do not fall
during transport, installation or removal.
• Use a crane and/or a transport truck for transportation.
• Only install the clamping block on machines with the
appropriate connection dimensions.

Assembly
20 05.00|0489065 KSH plus, KSH-LH plus, KSH-F plus |en
NOTE
• For vertical installation, the opening of the coolant drain (item
13) must always face downwards
• Surface "X"
is parallel to the guideway of the base jaws (item 2)
so the clamping block can be aligned on the machine table.
Assembly with clamping sleeves:
Mount the clamping block on the machine table together with
clamping sleeves (item 27) and screws (item 19).
Assembly with fitting screws:
There are two fittings in the housing (item 1) that, along with the
optional fitting screws (item 9), are used to center the clamping
block on the machine table with repeat accuracy. Do not realign
the clamping block after removing it from the machine table (e.g.,
after replacing the seals). When using fitting screws (item 9), use
them instead of the clamping sleeves (item 27) and the two
corresponding screws (item 19).
Connecting the clamping block
Make sure the power supply is off when connecting the clamping
block. Observe the "Basic safety notes" and the hydraulic wiring
diagram (5.3, Page 23).
The hydraulic screw fittings must be assembled in accordance
with the installation conditions recommended by the
manufacturer.
For the operation of the clamping block, the hydraulic oil must
correspond to a viscosity of 46 mm/s, and be filtered. Hydraulic
oil that is not prepared can wear out the clamping block
prematurely and lead to malfunctions.
CAUTION
Risk of work piece losses and damage to the automated system
due to loss of oil pressure caused by damaged hydraulic lines.
Always make sure the connections are tight, and protect the
hydraulic hoses or lines against hot chips and falling parts with
suitable protection covers.
