7. Test the blades for balance by balancing
the blade on a round shaft screwdriver
to check. If out of balance, when
sharpening, remove metal from the
heavy side until it balances evenly.
During sharpening the blade, follow
the original angle of grind. Grind each
cutting edge equally to keep the blade
balanced.
WARNING: An unbalanced
blade will cause excessive
vibration when rotating at high
speeds. It may cause damage to
mower and could break causing
personal injury.
8. Slide the blades (b) onto the spindle
shafts with the side marked "Grass Side"
(or with part number) facing the ground
when the mower is in the operating
position.
9. Replace the hex flange nuts (a) and
tighten to torque:
70 ft-lb (min.), 90 ft-lb (max.).
To ensure safe operation of your mower,
periodically check the blade bolt for correct
torque.

Off-Season Storage

Mower
The following steps should be taken to prepare
your lawn mower for storage.
• Clean and lubricate mower thoroughly
as described in Lubrication section on
page 12.
• Apply a coat of chassis grease to
mower's cutting blades to prevent
rusting.
• Refer to Engine Operator's Manual for
correct engine storage instructions.
• Do not use a pressure washer to clean
your unit.
• Store mower in a dry, clean area. Do not
store next to corrosive materials, such as
fertilizer.
When storing any type of power equipment in
a poorly ventilated or metal storage shed, care
should be taken to rust-proof the equipment.
Using a light oil or silicone, coat the equipment,
especially cables and all moving parts of your
lawn mower before storage.
Battery (If Equipped)
• The battery must be stored with a
full charge. Extended storage of a
discharged battery will reduce life and
capacity of the battery. For optimal
battery life, charge the battery once per
month while in storage.
• Remove electric starter push key (if
equipped) and keep in a safe place out
of the reach of children.
