Off-Season Storage
The following steps should be taken to prepare your lawn mower
for storage.
Clean and lubricate mower thoroughly as described in the
•
lubrication instructions.
Coat mower’s cutting blade with chassis grease to prevent
•
rusting.
Refer to engine manual for correct engine storage
•
instructions.
Secure side discharge chute to handle as shown in Fig. 7-2.
•
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.
Blade Care
WARNING:
When removing the cutting blade for
sharpening or replacement, protect your hands with
a pair of heavy gloves or use a heavy rag to hold the
blade.
Periodically inspect the blade adapter for cracks, especially if you
strike a foreign object. Replace when necessary. Follow the steps
below for blade service.
Disconnect spark plug boot from spark plug. Turn mower

on its side making sure that the air filter and the carburetor
are facing up.
Remove the bolt and the blade bell support which hold the

blade and the blade adapter to the engine crankshaft. See
Fig. 7-1.
Remove blade from the adapter for testing balance.
3.
Balance the blade on a round shaft screwdriver to check.
4.
Remove metal from the heavy side until it balances evenly.
When 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.
Place the blade on the adapter such that the side of the blade
