Changing The Engine Oil; Inspecting And Replacing The Spark Plug - Toro 38621 Operator's Manual

Changing the Engine Oil

Change the engine oil after the first 2 operating hours, then
yearly thereafter. If possible, run the engine just before
changing the oil because warm oil flows better and carries
more contaminants.
Max. fill: 26 oz. (0.77 l), type: automotive detergent oil with
an API service classification of SF, SG, SH, SJ, SL, or higher.
•
For temperatures above 32°F (0°C), use SAE 30W.
•
For temperatures between 0°F and 32°F (-18°C to 0°C),
use SAE 5W30 or SAE 10W.
•
For air temperatures below 0°F (-18°C), use SAE 0W30.
1. Clean the area around the oil drain cap (Figure 42).

2. Slide an oil drain pan under the drain extension and
remove the oil drain cap.
3. Drain the oil.
Note: Dispose of the used oil properly at a local
recycling center.
4. Install the oil drain cap.
5. Fill the crankcase with oil. Refer to Filling the Engine
Crankcase with Oil.
Lubricating the Hex Shaft
Lightly lubricate the hex shaft yearly with automotive engine
oil (Figure 43).

2. Aluminum friction plate
Important: Do not get oil on the rubber wheel or
the aluminum friction drive plate because the traction
drive will slip (Figure 43).

1. Drain the gasoline from the fuel tank.
2. Tip the snowthrower forward onto its auger housing
and block it so that it cannot fall.
3. Remove the back cover (Figure 44).

4. Move the speed selector lever to Position R2.
5. Dip your finger in automotive engine oil and lightly
lubricate hex shaft.
6. Move the speed selector lever to Position 6.
7. Lubricate the other end of the hex shaft.
8. Move the speed selector lever forward and rearward
a few times.
9. Install the back cover and return the snowthrower to
the operating position.
Inspecting and Replacing the
Spark Plug
Use a Champion RJ-19LM or equivalent spark plug. Check
and gap the spark yearly, and replace the plug if necessary.
1. Clean around the base of the spark plug.
2. Remove the spark plug.
3. Examine the spark plug and replace it if it is cracked,
fouled, dirty, or if the electrodes are worn.
Important: Do not clean the electrodes because
grit could enter the cylinder and damage the
engine.
4. Set the gap between the electrodes on the spark plug at
0.030 inch (0.76 mm) (Figure 45).

5. Install the spark plug by hand and then torque it to 15
ft-lb (20.4 N·m).
