Maintenance
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 ignition
and "Key Choice" keys.
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 27.
4.
Service the air cleaner; refer to Air Cleaner,
page 22.
5.
Grease the chassis; refer to Greasing and
Lubrication, page 27.
6.
Change the crankcase oil; refer to Engine Oil,
page 24.
7.
Remove the spark plug(s) and check its
condition; refer to Spark Plug, page 26. 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 30 ft–lb
(40 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 34. 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 27.
10. Prepare the machine for storage when non–use
occurs over 30 days. Prepare machine for storage
as follows.
A. Add a petroleum based
stabilizer/conditioner to fuel in the tank.
Follow mixing instructions from stabilizer
manufacture. Do not use an alcohol based
stabilizer (ethanol or methanol).
Note:
A fuel stabilizer/conditioner is most
effective when mixed with fresh
gasoline and used at all times.
B. Run engine to distribute conditioned fuel
through the fuel system (5 minutes).
C. Stop engine, allow to cool and drain the
fuel tank; refer to Fuel Tank, page 29.
D. Restart engine and run it until it stops.
E.
Choke or prime the engine. Start and run
engine until it will not start. Operate primer,
if equipped on machine, several times to
ensure no fuel remains in primer system.
F.
Dispose of fuel properly. Recycle as per
local codes.
IMPORTANT: Do not store
stabilizer/conditioned gasoline over 90 days.
