6.2 Preparing for Maintenance
6.2.1
Move the snow thrower to a level surface.
6.2.2
Stop the engine and wait for all moving parts to
stop.
6.2.3
Disconnect the spark plug wire.
6.3 Checking the Engine Oil Level
Service Interval:
Before each use or daily
Each time before using the snow thrower, first ensure
that the oil level is between the LOW/ADD and the
FULL marks on the dipstick.
6.3.1
Clean around the dipstick.
6.3.2
Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
6.3.3
Wipe the dipstick clean with a clean cloth.
6.3.4
Put the dipstick into the filler neck, then remove
it.
Note:
To ensure an accurate oil level reading, you
must fully install the dipstick.
6.3.5
Read the oil level on the dipstick.
6.3.6
If the oil lever is below the LOW/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 detergent oil. For extremely cold conditions (below
0
º
F or -18
º
C, use 0W-30 detergent oil.
6.3.7
Rotate the cap clockwise until it is tight.
6.4 Adjusting the Skids and Scraper
Service Interval:
Yearly
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.
（
FIG 19
）
6.4.1
Move the snow thrower to a lever surface.
6.4.2
Check the tire pressure in the tires. Refer to
Checking the Tire Pressure in Setup.
6.4.3
Loosen the 2 flange nuts that secure both skids
to the auger side plates until the skids slide up and
down easily.
6.4.4
Support the auger blades so that they are 1/8
inch
（
3mm
）
off the ground.
6.4.5
Check the scraper adjustment. The scraper
should be 1/8 inch
（
3mm
）
above and parallel to a level
surface.
A
：
For concrete and asphalt surfaces:
If the snow thrower does not clear the snow close
enough to the pavement, adjust the skids to lower the
scraper; if the pavement surfaces are cracked, rough,
or uneven, adjust the skids to raise the scraper.
B
：
For gravel surfaces:
Support the auger blades a few inches above the
ground, and adjust the skids to prevent the snow
thrower from picking up rocks.
6.4.6
To adjust the scraper, loosen the 5 mounting
screws, level the scraper, and tighten the mounting
screws.
6.4.7
Move the skids down as far as possible.
6.4.8
Tighten the 4 flange nuts that secure both skids
to the auger side plates.
FIG 19
6.5 Adjusting the Speed Selector
Adjust the speed selector linkage initially and when
the snow thrower is slow, first gear has no speed, or
the speed selector lever does not move into third gear.
6.5.1
Drain gasoline from the fuel tank and the engine
oil from the crankcase. Refer to Emptying the Fuel
Tank and to Changing the Engine Oil.
6.5.2
Tip the snow thrower forward and block it so
that it cannot fall.
6.5.3
Remove the upper and the bottom cover.
