Preparing for Maintenance
1. Move the machine to a level surface.
2. Stop the engine and wait for all moving parts to stop.
3. Disconnect the spark plug wire. Refer to Replacing
the Spark Plug.
Checking the Engine Oil Level
Service Interval:
Before each use or daily—Check
the engine oil level and add oil if
necessary.
1. Remove the dipstick, wipe it clean, then fully install
the dipstick.
2. Remove the dipstick and check the oil level
(Figure 43). If the oil level is below the Add mark
on the dipstick, add oil. Refer to Filling the Engine
with Oil.

Checking and Adjusting the
Skids and Scraper
Service Interval:
Yearly—Check the skids and the
scraper and adjust them if necessary.
All models except model 38657
Check the skids and the scraper to ensure that the auger
does not contact the paved or gravel surface. Adjust the
skids and the scraper as needed to compensate for wear.
1. Check the tire pressure. Refer to Checking the Tire
Pressure.
2. Loosen the nuts that secure both skids to the
auger sides until the skids slide up and down easily
(Figure 44).

1/2 inch (1.3 cm)
3. Support the side plates so that they are
at least
1/2
inch (1.3 cm) above a level surface.
Important:
The auger blades must be
supported above the ground by the skids.
4. Ensure that the scraper is 1/8 inch (3 mm) above
and parallel to a level surface.
Note:
If the pavement is cracked, rough, or uneven,
adjust the skids to raise the scraper. For gravel
surfaces, adjust the skids further down to prevent
the machine from picking up rocks.
5. Move the skids down until they are even with the
ground.
6. Firmly tighten the nuts that secure both skids to the
auger sides.
Note:
To quickly adjust the skids if they loosen,
support the scraper 1/8 inch (3 mm) off the
pavement, then adjust the skids down to the
pavement.
Note:
If the skids become excessively worn, you
can turn them over and set the unused side toward
the pavement.
