How do I fit Lister blades to the Star clipper?

How to fit a blade on the Lister Star Clipper.

• Firstly, disconnect the clipper from the power source
• Turn the clipper upside down and carefully fit the top blade to the clipper head (the crank roller must be in-between the socket of the top blade)
• Fit the bottom blade, ensuring the two holes are fitting over the comb pegs and pins
• Insert the tension bolt through the central hole
• Fit the tension spring over the tension bolt and screw the tension nut down as far as it will comfortably go
• Set the tension – using the marker on the tension nut as a guide, turn the tension nut back 1 ½ turns
