6.1 Performing crimping operation
DANGER
Electric shock hazard! Working in adverse outdoor conditions can cause electric shocks and/or short
circuits.
▶ Never work on electrically live lines while a thunderstorm is in progress.
▶ Call a halt to work immediately whenever weather conditions impair the insulation characteristics, vision
or movement of the workers.
WARNING
Risk of burn injury due to faulty crimping operations. Burns can result.
▶ Use crimping terminals of the correct type and size for the cable and use with the corresponding crimping
dies.
▶ Before every crimping operation, make sure that pivoting bar and lever are securely engaged.
▶ Listen for the acoustic signal and check that the piston has retracted. If no acoustic signal sounds and/or
the piston does not retract, the crimping operation is faulty.
WARNING
Risk of injury due to oil escaping under high pressure! Oil escaping under high pressure can injure the
skin and the eyes.
▶ Do not use the crimping tool if damage is visible.
▶ Do not use the crimping tool if oil escapes.
▶ Make sure that the piston retracts after every crimping operation.
▶ If the piston does not retract after the crimping operation, press the piston return switch for manual
retraction.
WARNING
Risk of injury due to flying fragments! Flying fragments present a risk of injury to the eyes and body.
▶ 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.
