Release the button and apply turning force as needed. To change the grip size, press the button again, reposition and reclamp.

Usage recommendations

For long tool life and safe operation, keep the pliers clean and lightly lubricated at the joint; avoid using them on live electrical circuits and do not use as a hammer. Select the correct jaw position for the workpiece to minimise slippage and damage.
