Changing The Transaxle Fluid - Toro 07253 Operator's Manual

Checking and Replacing the Spark Plug
1. Clean the area around the spark plugs so that foreign
matter cannot fall into the cylinder when the spark plug
is removed.
2. Pull the spark plug wires off of the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center electrode insulator to ensure that
there is no damage.
Figure 39
Important
A cracked, fouled, dirty, or malfunctioning
spark plug must be replaced. Do not sand-blast, scrape, or
clean the electrodes by using a wire brush because grit may
eventually release from the plug and fall into the cylinder.
The result is usually a damaged engine.
4. Set the air gap between the center and side electrodes at
0.030 in. (0.762 mm). Install the correctly gapped spark
plug and tighten the plug to 18–22 ft.-lb. (24–30 N m).
If a torque wrench is not used, tighten the plug firmly.
5. Install the spark plug wires.

Changing the Transaxle Fluid

Change the transaxle fluid every 800 operating hours or
yearly, whichever occurs first.
1. Position the vehicle on a level surface, set the parking
brake, turn the ignition off, and remove the key.
2. Remove the drain plug from the right side of the
reservoir (Fig. 40) and let the fluid flow into a drain
pan. Install and tighten the plug when the fluid stops
draining.
Note: Dispose of used oil at a certified recycling center.
