How to remove the A5 blades
On the back of the clipper, just below the blade,there is a black metal latch that looks like an L-bracket with a rolled over edge. Push this latch up towards the blade. While you are holding the latch in, gently pull the top of the blade away from the clipper. This blade is now in the fully open position. The blade will move only an inch or so, but you should feel it give a little snap when it gets into the open position. The open position is almost vertical but the blades still lean towards the clipper.
Once you've pulled the blade into this open position, simply slide the blade up off of the single silver lever that it is sitting on.
Caution: The lever will need to be in the open position to re-install the blade. Be careful not to push that silver lever in towards the clippers while there is no blade on it. There is a large spring on it, and it will be quite difficult to get it back into the open position. If you should accidentally close the lever, you will need to use a small flat-head screwdriver to pry it back into the open position. From the side, get just a little bit under and GENTLY work the screwdriver under and then up. If you are struggling to re install the blades, it may be easier once the blades have been positioned on to the lever to turn the clipper/trimmer on as you push the blade back towards to clipper/trimmer.
F5 Connection blade (Jewel and Jester Models)
This cutter and comb come attached to one another as a set. The cutter is ceramic and is longer lasting than traditional metal.
To remove, simply push the blade back from the trimmer until it snaps off. Then to re-install, line the plastic inserts up on the inside of the head of the trimmer and then push the blade back into place as it came off.
