guard as possible. To tighten the nut, turn the spanner in
the opposite direction to the direction of rotation (Caution!
left-hand thread).
When loosening and tightening the saw blade nut, there is a
risk of injury from the teeth of the saw blade. You should
therefore always ensure that your hand is shielded by the
blade guard when doing this. Always use a socket spanner
with a shaft that is long enough to allow this. The arrow in the
diagram shows the area where you should operate the socket
spanner when loosening or tightening the nut.
