Maintenance Safety
Read the following safety precautions before performing any maintenance on the machine:
-
Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.
-
Always wear eye protection while performing an adjustment or repair to protect your eyes from foreign objects that the machine may throw.
-
Check all fasteners at frequent intervals for proper tightness to ensure that the machine is in safe working condition.
-
Do not change the governor settings on the engine.
Purchase only genuine Toro replacement parts and accessories.
Preparing for Maintenance
-
Move the machine to a level surface.
-
Shut off the engine and wait for all moving parts to stop.

Checking and Adjusting the Skids and Scraper
Maintenance Service Interval | Maintenance Procedure |
---|---|
Yearly |
|
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.
-
Check the tire pressure; refer to Checking and Adjusting the Tire Pressure.
-
Loosen the nuts that secure both skids to the auger sides until the skids slide up and down easily.
Important: The auger blades must be supported above the ground by the skids.
-
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.
-
Move the skids down until they are even with the ground.
-
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.
Checking and Adjusting the Traction Cable
Maintenance Service Interval | Maintenance Procedure |
---|---|
After the first 2 hours |

-
If the auger/impeller cable is properly adjusted but a problem remains, contact an Authorized Service Dealer.
Checking the Auger-Gearbox-Oil Level
Maintenance Service Interval | Maintenance Procedure |
---|---|
Yearly |
|
-
Move the machine to a level surface.
-
Clean the area around the pipe plug (Figure 33).
-
Remove the pipe plug from the gearbox.
-
Check the oil level in the gearbox. The oil should be 9.5 mm (3/8 inch) below the filler opening.
-
If the oil level is low, add GL-5 or GL-6, SAE 80-90 EP gear oil lubricant to the gearbox until the oil level is 9.5 mm (3/8 inch) below the filler opening.
Note: Do not use synthetic oil.
-
Install the pipe plug in the gearbox.
Changing the Engine Oil
Maintenance Service Interval | Maintenance Procedure |
---|---|
After the first 5 hours |
|
Yearly |
|
If possible, run the engine for a few minutes before changing the oil because warm oil flows better and carries more contaminants.
Engine oil capacity | 0.70 L (24 fl oz)* |
Oil viscosity | Refer to Figure 35. |
API service classification | SJ or higher |
*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.
Use Figure 35 below to select the best oil viscosity for the outdoor temperature range expected:
-
Move the machine to a level surface.
-
Clean the area around the oil-drain cap (Figure 34).
-
Slide an oil-drain pan under the drain extension and remove the oil-drain cap.
-
Drain the oil.
Note: Dispose of the used oil properly at a local recycling center.
-
Install the oil-drain cap and tighten it securely.
-
Clean around the oil fill/dipstick.
-
Unscrew the dipstick and remove it.
-
Carefully pour about 3/4 of the engine capacity of oil into the oil-fill tube.
Use Figure 35 to select the best oil viscosity for the outdoor temperature range expected:
-
Wait 3 minutes for the oil to settle in the engine.
-
Wipe the dipstick clean with a clean cloth.
-
Insert the dipstick into the oil-fill tube, screw it in, then remove the dipstick.
-
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.
-
-
Install the dipstick into the oil-fill tube securely.
Lubricating the Hex Shaft
