Cleaning and Storage
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” 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.
IMPORTANT: You can wash the machine
with mild detergent and water. Do not
pressure wash the machine. Avoid excessive
use of water, especially near the control panel,
lights, engine, and the battery.
3. Check the brake; refer to Brake, page 24.
4. Service the air cleaner; refer to Air Cleaner,
page 19.
5. Grease the chassis; refer to Greasing and
Lubrication, page 24.
6. Change the crankcase oil; refer to Engine Oil,
page 21.
7. Remove the spark plug(s) and check its
condition; refer to Spark Plug, page 23. 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 15 ft–lb
(20.4 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 31. 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
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 24.
10. During long-term storage, either drain gasoline
from the fuel tank (step A) or add a fuel
stabilizer/conditioner additive to a full tank of
gasoline (step B).
A. Drain gasoline from the fuel tank; refer to
Fuel Tank, page 26. After fuel is drained,
start the engine and let it idle until all
gasoline is consumed and the engine stops.
This eliminates gum-like buildup in the fuel
system, which causes hard starting. Try to
start the engine two more times to assure
that no gasoline is in the fuel system.
B. Add the correct amount of a fuel
stabilizer/conditioner to a full tank of
gasoline.
Note: Stabilizer/conditioners normally
preserve gasoline for six to eight
months.
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.
