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, (3.2, Page 18).
• Make sure that the product is a sufficient size for the
application.
• Ensure the contact surfaces of the interface and recesses
towards the locating surfaces above the bolting points are kept
clean at all times.
• Under all circumstances, prevent any type of chips from
entering the interface and prevent cooling emulsion from
seeping into the interface. This may occur particularly during
vertical alignment of the clamping pin axis. The best way to
ensure both of these requirements is to use the SDE protection
covers or the cone seal provided for the quick-change pallet
system. If the interface should become filled with cooling
emulsion, initiate the unlocking process and allow the interface
to dry out while in an actuated state. It may be blown out
carefully with compressed air but only when using the required
protective equipment.
• Only use high-quality cooling emulsions with anti-corrosive
additives during processing.
• Protect the cone seal from high-pressure direct spraying with
cooling emulsion.
