▶ Wear eye protection and protective gloves.
▶ Use suitable connection material in combination with the correct crimping dies.
▶ Before and during the crimping operation, make sure that the crimping dies are correctly positioned.
CAUTION
Short-circuit due to formation of flash produced by crimping operations! A faulty crimping operation
can lead to the formation of flash, which can cause short-circuiting/arcing.
▶ Use the correct crimping die.
▶ Use suitable connection material.
▶ Remove the flashes that form in the course of crimping work.
In cold weather the hydraulic oil can thicken and slow the crimping operation. Perform 5 to 10 empty
crimping operations to heat up the crimping tool.
