Checking The Engine Oil Level; Changing The Engine Oil; Checking/Adding Auger Gear Box Grease - Toro 38078 Operator's Manual

POTENTIAL HAZARD
If you leave the wire on the spark plug, someone could start the engine.
WHAT CAN HAPPEN
Accidental starting of engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
Pull the wire off of the spark plug before you do any maintenance. Also, push it aside so it
does not accidentally contact the spark plug.

Checking the Engine Oil Level

Check the oil level every five operating hours or each
time you use the snowthrower.
1. Move the snowthrower to a level surface.
2. Clean the area around the dipstick (Fig. 14).
3. Remove the dipstick from the crankcase (Fig. 14).
4. Wipe the dipstick clean with a clean cloth.
5. Fully install the dipstick.
Note:
To ensure an accurate oil reading, you must fully
install the dipstick.
6. Remove the dipstick from the crankcase (Fig. 14).
7. Read the oil level on the dipstick.
8. If the oil level is below the Full mark, slowly add oil,
checking the level frequently, until the dipstick reads
full.
Use only a high–quality, SAE 5W–30 or SAE 10
weight, detergent oil, having the American Petroleum
Institute (API) "service classification"—SE, SF or SG.
IMPORTANT:
Do not overfill the crankcase and run
the engine; engine damage will result. Drain the excess
oil until the oil level on the dipstick reads Full.
9. Install the dipstick.

Changing the Engine Oil

Initially, change the oil after the first two hours of
operation; thereafter, under normal conditions, change the
oil as given in the Recommended Maintenance Schedule
on page 16. If possible, run the engine just before
changing oil because warm oil flows better and carries
more contaminants.
CAUTION
1. Pull the wire off of the spark plug and ensure that the
wire does not contact the plug (Fig. 19).
2. Clean the area around the oil drain plug (Fig. 20).
3. Slide the oil drain pan below the drain extension and
remove the oil drain plug (Fig. 20).
1. Drain plug
4. After draining the oil, install the oil drain plug.
5. Fill the crankcase with oil. Refer to Filling the Engine
with Oil on page 10.
6. Wipe up any spilled oil.
Checking/Adding Auger Gear
Box Grease
Check the auger gear box grease initially, after every ten
hours of use, and upon removal from annual storage.
1. Pull the wire the off of the spark plug and ensure that
the wire does not contact the plug (Fig. 19).
2. Position the snowthrower on a level surface.
3. Clean the area around the pipe plug (Fig. 21).
4. Remove the pipe plug from the gear box (Fig. 21).
