General Maintenance; Replacing The Cutting Blade - Ryobi P1104 Manual Del Operador

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.
NOTICE:
Never use a hose, water, or any liquids to clean the lawn
mower, as water and liquids can damage electronic com-
ponents and the battery pack. Remove any buildup of
grass and leaves on or around the motor cover. Wipe the
mower clean with a dry cloth occasionally.
LUBRICATION
All of the bearings in this product are lubricated with a
sufficient 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.
Contact 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 from the battery port.
 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).
MAINTENANCE
 Remove the blade nut, spacer, and blade.
 Place the new blade on the shaft against the blade posts.
Ensure blade is properly seated with shaft going 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.
 Replace the 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
310 - 360 in.lbs.
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.
