2 Basic safety notes

Improper handling, assembly and maintenance of this product

may result in risk to persons and equipment if this operating

manual is not observed.

2.1 Appropriate use

lThe product is used for clamping metal and plastic workpieces

on machine tools.

lThe product may only be used within the scope of its technical

data.

lThe product is intended for industrial and commercial use.

lAppropriate use of the product includes compliance with all

instructions in this manual.

lThe maximum speed and the necessary clamping force must

be determined by the operator for each clamping task in

accordance with the valid standards or technical

specifications of the manufacturer.

(See also "Calculation for clamping force and speed of

rotation" in the chapter "Technical data").

lUse suitable top jaws with a suitable interface.

lThe interference circuit diameter of the workpiece must be

smaller or at most equal to the outer diameter of the

clamping device.

lThe workpiece must not experience plastic deformation under

clamping force (clamping pressures are permissible).

2.2 Inappropriate use

The product is not being used appropriately if:

lthe product is used as a press, a punch, a toolholder, a load-

handling device or as lifting equipment.

lthe specified technical data for use of the product are

exceeded.

lworkpieces are not properly clamped, paying particular

attention to the specified clamping forces.

lthe top jaws are not mounted properly.

lthe product is not being operated properly.

lthe product is operated in the stroke end positions.

lthe guideways are overloaded due to the chuck jaws being

too high or the clamping point being selected too high.

lthe product has been insufficiently maintained.

lthe product is brought into contact with aggressive media,

especially acids.

lthe product is used in abrasive blasting processes, especially

sandblasting.

2.3 Structural changes

Implementation of structural changes

Modifications, changes or reworking, e.g. additional threads,

holes, or safety devices, can damage the product or impair its

functionality or safety.

lStructural changes should only be made with the written

approval of SCHUNK.

2.4 Spare parts

Use of unauthorized spare parts

Using unauthorized spare parts can endanger personnel and

damage the product or cause it to malfunction.

Only use original spare parts and spares authorized by SCHUNK.

2.5 Ambient conditions 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 in

the service life of the product.

lMake sure that the product is only used within its defined

application parameters.

lEnsure that the product is of a sufficient size for the

application.

lEnsure that maintenance and lubricating intervals are

observed.

lOnly use cooling emulsions with anti-corrosive additives

when machining.

Depending on the operating conditions, the function and

clamping force must be checked after a certain period of

operation.

With the smallest possible actuation pressure on the clamping

cylinder, the base jaws should move evenly. This method is not a

substitute for measuring the clamping force.

If the clamping force has dropped too much or if the base jaws

and/or the release mechanism no longer move properly, the

clamping device must be disassembled, cleaned, and relubricated.

2.6 Material limitations

The product is made of steel alloys, elastomers, aluminum alloys

and brass. In addition, Linomax plus grease, Branotect anti-rust

oil and Renolit HLT2 are incorporated into the product as auxiliary

and operating materials. The safety data sheet for LINOMAX plus

can be found at www.schunk.com.

2.7 Chuck Jaws

Requirements of the chuck jaws

Rotational or if applicable, accumulated energy, can make the

product unsafe and risk the danger of serious injuries and

considerable material damage.

lChange chuck jaws at a standstill and without a clamped

workpiece.

lDo not use welded jaws.

lDesign the chuck jaws to be as light and as low as possible.

The clamping point must be as close as possible to the chuck

face (clamping points at a greater distance lead to greater

surface pressure in the jaw guidance and can significantly

reduce the clamping force).

lIf the clamping point is at a greater distance from the

housing, the operating pressure must be reduced.

lAfter a collision, the clamping device and the chuck jaws must

be subjected to a crack detection test before being used

again. Replace damaged parts with original SCHUNK spare

parts.

lThe chuck jaw mounting screws and if present, the T-nuts,

must be replaced if there are signs of wear or damage. Only

use screws of quality grade 12.9 in compliance with the

specified tightening torques. For clamping devices with fine

serration, the jaw mounting screws must be screwed into the

holes closest to the clamping point.

2.8 Personnel qualifications

Inadequate qualification of personnel

Any work on the product by inadequately qualified personnel can

lead to serious injuries and considerable material damage.

lAll work must be performed by appropriately qualified

personnel.

lPersonnel must have read and understood the complete

manual before beginning any work on the product.

lObserve country-specific accident prevention regulations and

the general safety notes.

The following personnel qualifications are required for the

various activities on the product:

Qualified electrician Qualified electricians have the professional training, knowledge,
