Cleaning and Storage

1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
"STOP" to stop the engine. Remove the key.
2. Remove grass clippings, dirt, and grime from the
external parts of the entire machine, especially
the engine. Clean dirt and chaff from the outside
of the engine's cylinder head fins and blower
housing; refer to Check for Debris, page 12.
IMPORTANT: You can wash the machine
with mild detergent and water. DO NOT
PRESSURE WASH THE MACHINE.
Pressure washing may damage the electrical
system or wash away necessary grease at
friction points. Avoid excessive use of water,
especially near the control panel, lights,
engine, and the battery.
3. Check the brake; refer to Brake, page 31.
4. Service the air cleaner; refer to Air Cleaner,
page 24.
5. Grease the chassis; refer to Greasing and
Lubrication, page 30.
6. Change the crankcase oil; refer to Engine Oil,
page 26.
7. Remove the spark plug(s) and check its
condition; refer to Spark Plug, page 29. With the
spark plug(s) removed from the engine, pour two
tablespoons of engine oil into the spark plug
hole. Now use the electric starter to crank the
engine and distribute the oil inside the cylinder.
Install the spark plug(s) and tighten it to 17 ft–lb
(23 Nm). Do not install the wire on the spark
plug(s).
8. Remove the battery from the chassis, check the
electrolyte level, and charge it fully; refer to
Battery, page 39. Do not connect the battery
cables to the battery posts during storage.
IMPORTANT: The battery must be fully
charged to prevent it from freezing and being
damaged at temperatures below 32 F (0 C). A
46
fully charged battery maintains its charge for
about 50 days at temperatures lower than
40 F (4 C). If the temperatures will be above
40 F (4 C), check the water level in the
battery and charge it every 30 days.
9. Check the tire pressure; refer to Tire Pressure,
page 31.
10. For long–term storage (more than 90 days) add
stabilizer/conditioner additive to fuel in the tank
(1 oz. per gallon) (8 ml per liter).
A. Run the engine to distribute conditioned
fuel through the fuel system (5 minutes).
B. Stop the engine, allow it to cool and drain
the fuel tank; refer to Fuel Tank, page 33, or
operate the engine until it stops.
C. Restart the engine and run it until it stops.
Repeat, with the choke ON, until the engine
will not restart.
D. Dispose of fuel properly or use within 90
days for other applications. Recycle in
accordance with local codes.
11. Check and tighten all bolts, nuts, and screws.
Repair or replace any part that is damaged or
defective.
12. Paint all scratched or bare metal surfaces. Paint
is available from your Authorized Service
Dealer.
13. Store the machine in a clean, dry garage or
storage area. Remove the key from the ignition
switch and keep it in a memorable place. Cover
the machine to protect it and keep it clean.
