Installing the Discharge Tunnel

handle and moving it rearward (Fig. 5). Hold the
discharge door handle to prevent the spring-loaded
door from closing while you insert the plug.

2. Since the plug is slightly wider than the discharge
tunnel opening, rotate the plug clockwise slightly
while inserting it (Fig. 5).
Note: Ensure that the arrow on the plug decal points
upward.
3. Push the plug all the way in until the spring clip on the
bottom of the plug clicks into place, locking the plug
securely into the discharge tunnel (Fig. 6).

Before Starting

Filling the Crankcase with Oil

Initially, fill the crankcase with 30 ounces (0.88 liters) of
oil. Use only high-quality SAE 30 or SAE 10W30 weight
detergent oil that has the American Petroleum Institute
(API) service classification SF, SG, SH, or SJ.

Note: When the crankcase is empty, pour about 3/4 of the
crankcase capacity of oil in the crankcase, then follow the
procedure in this section.
To add oil:
1. Move the lawn mower to a level surface.
2. Clean around the dipstick (Fig. 7).
3. Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
4. Wipe the dipstick clean with a clean cloth.
5. Insert the dipstick into the filler neck, then remove it.
Note: To ensure an accurate oil level reading, you must
fully install the dipstick.
6. Read the oil level on the dipstick (Fig. 7).
7. If the oil level reading 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.
