REPLACING BLADES
See Figures 13 - 15, page 13.
The planer blades are reversible. When one edge becomes
dull, the blade can be reversed so that the other side can
be used.
Always replace or reverse blades in pairs. Do not attempt
to sharpen blades. If the blades in the planer show signs of
becoming dull, chipped, or damaged in any way, replace them.
When replacing the blades, use recommended replacement
blade only, RYOBI part number 690861001.
WARNING:
The blades are sharp. Use extreme caution when
replacing blades. Failure to heed this warning can result
in serious personal injury.
 Unplug the planer.
 Secure the planer in an upside-down position.
 Loosen the three screws securing the blade on the blade
holder using the blade wrench provided.
NOTE: Do not over-loosen the screws. If screws are too
loose, alignment of the new blade will not be accurate.
NOTE: Before removing the old blades, take notice of
the direction of cut as well as how the tapered edge of
the old blades are oriented. The tapered edge of the new
blades must be in the same orientation as the original
blades, with the tapered edge on the same side as the
screw heads and the flat edge facing the cutter block.
 Push the blade (to the right) out of the blade holder using
the tip of a screwdriver.
 Remove the old blade from the blade holder.
