Replacing The Cutting Blades - Ryobi RM480e Traduction Des Instructions Originales

REPLACING THE CUTTING BLADES

See fig. 24 - 26
WARNING
Use only original replacement blades and
blade bolts authorised by the manufacturer
of your ride-on mower. Use of blades
and blade bolts that are not authorised is
hazardous and may damage your ride-on
mower.
1. Make sure that the direction control
switch is in neutral (N) position, and blade
engage knob is down.
2. Turn off the product, engage the parking
brake, and remove the start key.
3. Set the cutting deck to the maximum
height to allow access to the blades.
NOTE: If necessary, raise the mower by
placing on a lift or using a jack and jack
stands, or remove the cutting deck as
described in the previous section to gain
access to the blades.
WARNING
If raising the mower to access the blades,
make sure that the mower is properly
secured and the parking brake is engaged
before proceeding. Failure to properly
secure the mower could cause it to fall,
resulting in death or possible serious
personal injury.
4. Wedge a block of wood between the
blade and mower deck to prevent the
blade from turning.
5. Loosen the blade nut by turning it
counterclockwise (as viewed from bottom
of mower) using a 15 mm wrench or
socket (not provided).
6. Remove the blade nut, spacer, blade
insulator, and blade.
7. Place the new blade on the shaft against
the corresponding blade posts. Ensure
that blade is properly seated with the
shaft going through centre blade hole
and the two blade posts inserted into their
respective holes on the blade. Make sure
that the blade is installed with the curved
ends pointing up toward the mower deck
and not down toward the ground. When
seated properly, the blade should be flat
against the blade posts.
8. Reinstall the blade insulator and spacer,
making sure that the flat sides on each
piece align and the straight sides of the
opening on the spacer are aligned with
the straight sides of the blade shaft.
NOTE: Make sure that all the parts are
replaced in the exact order in which they
were removed.
9. Thread the blade nut on the shaft and
finger tighten.
10. Torque the blade nut down clockwise
using a torque wrench (not provided) to
ensure the bolt is properly tightened. The
recommended torque for the blade nut is
68 - 74 Nm (600-650 in. lbs.)
WARNING
Ensure that the blade is properly seated
and the blade nut is tightened to the torque
specifi cations above. Failure to properly
attach the blade could cause it to come
loose and result in possible serious personal
injury.
Repeat the steps with the second blade, if
needed.
