Lubricating The Snowthrower; Replacing The Spark Plug; Emptying The Fuel Tank - Toro 38078 Operator's Manual

5. Adjust the forward speed by rotating the speed selector
rod in the trunnion (Fig. 6).
Lengthening the rod makes the forward speed faster.
Shortening the rod makes the forward speed slower.
6. Insert the speed selector rod into the speed selector
arm and secure it with the washer and cotter pin.

Lubricating the Snowthrower

Lightly lubricate all moving parts according to the
Recommended Maintenance Schedule on page 16.
1. Pull the wire off of the spark plug and ensure that the
wire does not contact the plug (Fig. 19).
2. Drain gasoline from fuel tank. Refer to Emptying the
Fuel Tank on page 22.
3. Tip the snowthrower forward onto the auger housing
and block it so that it cannot fall.
4. Remove the eight screws that secure the back and
bottom covers and remove the covers (Fig. 30).

6. Wipe up any excess oil.
7. Lightly grease the axle gear (Fig. 31).
8. Wipe up any excess grease.
IMPORTANT: Do not get oil or grease on the rubber
wheel or friction drive plate. This can cause the wheel
to slip and the rubber to deteriorate.

Replacing the Spark Plug

Check the spark plug periodically as given in the
Recommended Maintenance Schedule on page 16. If the
electrodes in the center of the plug are dark or have
deteriorated, install a new Champion RJ–19LM spark plug
or equivalent.
1. Clean the area around the spark plug.
2. Pull the wire off of the spark plug (Fig. 19) and
remove the plug from the cylinder head.
IMPORTANT:
Replace a cracked, fouled or dirty
spark plug. Do not sand blast, scrape or clean
electrodes because grit may eventually release from the
plug and fall into the cylinder, causing engine damage.
3. Set the air gap between the electrodes of the spark
plug at 0.030 in. (0.76 mm) (Fig. 33).
4. Install the spark plug in the cylinder head.
5. Torque the plug to 15 ft-lb (20.4 N m).
6. Push the wire onto the spark plug (Fig. 19).

Emptying the Fuel Tank

1. Pull the wire off of the spark plug and ensure that the
wire does not contact the plug (Fig. 19).
