Maintenance; Lubrication; Replacing The Cutting Blade; General Maintenance - Ryobi RY40104 Manuel D'utilisation

WARNING:
Before performing any maintenance or cleaning the lawn
mower, make sure the mower blades come to a complete
stop and the batteries and start key are removed to avoid
accidental starting and possible serious personal injury.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
WARNING:
When servicing, use only authorized replacement parts.
Use of any other parts can create a hazard or cause
product damage.
WARNING:
Never use a hose, water, or any liquids to clean or
rinse off the lawn mower. Corrosive liquids, water, fer-
tilizers, and chemicals used to treat lawns can enter the
lawn mower and/or battery compartment and damage
electronic components and/or the battery pack, which
can result in a short circuit, increased risk of fire, and
serious personal injury. Remove any buildup of grass
and leaves on or around the mower housing and/or un-
derneath the mower deck. Wipe the mower clean with a
dry cloth occasionally.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,
etc. Tighten securely all fasteners and caps and do not
operate this product until all missing or damaged parts
are replaced. Please contact customer service or an
authorized service center for assistance.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken, or
destroy plastic which can result in serious personal injury.

MAINTENANCE

Remove any build-up of grass and leaves on or around the
motor cover. Wipe the mower clean with a dry cloth occa-
sionally. Do not use water.

LUBRICATION

All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
bearing lubrication is required.
WARNING:
Always protect hands by wearing heavy gloves and/or
wrapping the cutting edges of the blade with rags and
other material when performing blade maintenance. Con-
tact with the blade could result in serious personal injury.

REPLACING THE CUTTING BLADE

See Figures 13 - 14.
NOTE: Only use authorized replacement blades.
 Stop the motor and remove the start key. Allow blade to
come to a complete stop.
 Remove the battery pack.
 Turn the mower on its side.
 Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.
 Loosen the blade nut by turning it counterclockwise (as
viewed from bottom of mower) using a 15 mm wrench or
socket (not provided).
 Remove the blade nut, spacer, blade insulator, and blade.
 Make certain the blade support is pushed completely
against the motor shaft.
 Place the new blade on the shaft against the blade
support. Ensure blade is properly seated with shaft go-
ing through center blade hole and the two blade posts
inserted into their respective holes on the blade. Make
sure it 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
support.
 Replace the blade insulator and spacer, then thread the
blade nut on the shaft and finger tighten.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
 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
350-400 in. lbs.
WARNING:
Ensure blade is properly seated and the blade nut is
tightened to the torque specifications above. Failure to
properly attach the blade could cause it to come loose
and result in possible serious personal injury.
