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. Loosen the nuts that secure both skids to the auger sides until the skids slide up and down easily.

   

   Figure 23

   1. 3 mm (1/8 inch)

   Important: The auger blades must be supported above the ground by the skids.

2. Ensure that the scraper is 3 mm (1/8 inch) 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.

3. Move the skids down until they are even with the ground.

4. Firmly tighten the nuts that secure both skids to the auger sides.

   Note: To quickly adjust the skids if they loosen, support the scraper 3 mm (1/8 inch) 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.

1. Move the machine to a level surface.

2. Clean the area around the pipe plug and remove the pipe plug from the gearbox (Figure 33).

   Note: If needed, use pliers to assist in removing the pipe plug.

   

   Figure 33

3. Check the oil level using a suitable measuring device, such as a clean cable tie. The oil should be approximately 3.8 cm (1.5 inches) below the filler opening (Figure 34).

   

   Figure 34

4. If the oil level is low, add GL-5 or GL-6, SAE 85-95 EP gear oil lubricant to the gearbox, then check the oil level again.

   Note: Do not use synthetic oil.

5. Install the pipe plug in the gearbox.

If possible, run the engine for a few minutes before changing the oil because warm oil flows better and carries more contaminants.

*There is residual oil in the crankcase after you drain the oil. Do not pour the entire capacity of oil into the crankcase. Fill the crankcase with oil as directed in the following steps.

1. Move the machine to a level surface.

2. Clean the area around the oil-drain nut (Figure 35).

   

   Figure 35

   1. Oil-drain nut

3. Slide an oil-drain pan under the drain extension and remove the oil-drain nut.

4. Drain the oil.

   Note: Dispose of the used oil properly at a local recycling center.

5. Install the oil-drain nut and tighten it securely.

6. Clean around the oil fill/dipstick.

7. Unscrew the dipstick and remove it.

8. Carefully pour about 3/4 of the engine capacity of oil into the oil-fill tube.

   Use Figure 36 to select the best oil viscosity for the outdoor temperature range expected:

   

   Figure 36

9. Wait 3 minutes for the oil to settle in the engine.

10. Wipe the dipstick clean with a clean cloth.

11. Insert the dipstick into the oil-fill tube and screw it in, then remove the dipstick.

12. Read the oil level on the dipstick.

    • If the oil level on the dipstick is too low, carefully pour a small amount of oil into the oil-fill tube, wait 3 minutes, and repeat steps 10 through 12 until the oil level on the dipstick is correct.

    • If the oil level on the dipstick is too high, drain the excess oil until the oil level on the dipstick is correct.

    Important: If the oil level in the engine is too low or too high and you run the engine, you may damage the engine.

13. Install the dipstick into the oil-fill tube securely.

Use a Toro spark plug or equivalent (Champion® RN9YC or NGK BPR6ES).
