Checking The Tire Pressure; Cleaning The Cooling System; Draining The Fuel Tank - Toro 71209 Operator's Manual

Checking the Spark Plug
1. Look at the center of the spark plug (Fig. 24). If you see
light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator
usually means that the air cleaner is dirty.

Important
Do not clean the spark plug. Always
replace the spark plug when it has a black coating, worn
electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 24) and bend the side electrode if the gap is not
correct.
Installing the Spark Plug
1. Install the spark plug and metal washer.
Note: Make sure that the air gap is set correctly.
2. Tighten the spark plug to 15 ft-lb (20 N m).
3. Connect the wire to the spark plug (Fig. 23).
4. Close the hood.

Checking the Tire Pressure

Maintain the air pressure in the front and rear tires at 20 psi
(138 kPa). Check the pressure at the valve stem (Fig. 25)
after every 25 operating hours or yearly, whichever occurs
first. Check the tires when they are cold to get the most
accurate pressure reading.

Draining the Fuel Tank

Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Park the tractor so that the left front side is slightly
lower than the right side to ensure that the fuel tank
drains completely.
2. Disengage the blade (PTO).
3. Shift the ground speed lever into Neutral.
4. Set the parking brake.
5. Stop the engine and wait for all moving parts to stop.
6. Remove the ignition key.
7. Open the hood.
