Checking The Engine Oil Level; Checking The Auger Gearbox Grease; Adjusting The Skids And The Scraper - Toro 38078 Operator's Manual

If you leave the wire on the spark plug, someone could accidently start the engine and seriously
injure you or other bystanders.
Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so
that it does not accidentally contact the spark plug.

Checking the Engine Oil Level

Every time you use the snowthrower, first ensure that the
oil level is between the Add and the Full marks on the
dipstick.
1. Stop the engine and wait for all moving parts to stop.
2. Move the snowthrower to a level surface to ensure an
accurate oil level reading.
3. Clean around the dipstick (Fig. 13).
4. Remove the dipstick by rotating the cap
counterclockwise and pulling it out (Fig. 13).
5. Wipe the dipstick clean with a clean cloth.
6. Install the dipstick into the filler neck, then remove it.
Note: To ensure an accurate oil level reading, you must
fully install the dipstick.
7. Read the oil level on the dipstick.
8. If the oil level is below the Add mark on the dipstick,
slowly pour only enough oil into the filler hole to raise
the oil level to the Full mark on the dipstick.
Note: Use only a high-quality, SAE 5W–30 or SAE 10
weight detergent oil that has the American Petroleum
Institute (API) service classification SF, SG, SH, or SJ.
For extremely cold conditions (below 0 F or –18 C),
use 0W–30 weight detergent oil that has the American
Petroleum Institute (API) service classification SF, SG,
SH, or SJ.
Important
Do not overfill the crankcase with oil and
run the engine; engine damage will result. Drain the excess
oil until the oil level on the dipstick reads Full.
9. Insert the dipstick into the filler neck and rotate the cap
clockwise until it is tight.
Checking the Auger Gearbox
Grease
Check the auger gearbox initially, after every 10 operating
hours, and when you remove the snowthrower from annual
storage.
1. Stop the engine and wait for all moving parts to stop.
2. Move the snowthrower to a level surface.
Caution
3. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 18).
4. Clean the area around the pipe plug (Fig. 21).
1. Pipe plug
5. Remove the pipe plug from the gearbox (Fig. 21).
6. Check the level of grease in the gearbox. The grease
should be visible through the opening.
7. If the level of grease is low, add Lubriplate MAG-1
grease (a low-temperature, high-pressure grease) to the
gearbox until the point of overflow.
8. Install the pipe plug in the gearbox.
9. Connect the wire to the spark plug.
Adjusting the Skids and the
Scraper
Adjust the skids and the scraper initially and then as needed
to ensure that the auger does not contact the paved or gravel
surface. Also, adjust them as needed to compensate for
wear.
1. Stop the engine and wait for all moving parts to stop.
2. Move the snowthrower to a level surface.
3. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 18).
4. Check the tire pressure in the tires. Refer to Checking
the Tire Pressure on page 13.
5. Loosen the 4 flange nuts that secure both skids to the
auger side plates (Fig. 22) until the skids slide up and
down easily.
