Servicing The Spark Plug - Toro 30436 Operator's Manual

Changing the Engine Oil
1. Start the engine and let it run five minutes. This warms
the oil so it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to assure the oil drains
completely.
3. Disengage the PTO and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose. Rotate oil drain
valve to allow oil to drain (Fig. 31).
7. When oil has drained completely, close the drain
valve.
8. Remove the drain hose (Fig. 31).
Note: Dispose of the used oil at a recycling center.

Servicing the Spark Plug

Service Interval and Specification
Check the spark plug(s) after every 100 operating hours.
Make sure the air gap between the center and side
electrodes is correct before installing the spark plug. Use a
spark plug wrench for removing and installing the spark
plug(s) and a gapping tool/feeler gauge to check and
adjust the air gap. Install a new spark plug(s) if necessary.
Type: Championr RCJ8Y or NGKr BPR4ES
Air Gap: 0.030 inch (.75 mm)
Removing the Spark Plug
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Pull the wire(s) off the spark plug(s) (Fig. 33). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.
