the height/bevel adjusting handwheel clockwise.

To loosen the blade:
 Using the open end blade wrench, place the flat open
end on the flats on the arbor shaft.
 Insert the closed end blade wrench over the blade nut.
Holding both wrenches firmly, pull the closed end wrench
forward to the front of the machine.
To tighten the blade:
 Using the open end blade wrench, place the flat open
end into the flats on the arbor shaft.
 Insert the closed end blade wrench over the blade nut.
Holding both wrenches firmly, push the closed end wrench
to the back of the machine. Make sure the blade nut is
securely tightened. Do not overtighten.
