Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Inspect the traction cable and adjust it if necessary. • Inspect the auger/impeller cable and adjust it if necessary. After the first 5 hours • Change the engine oil. Before each use or daily • Check the engine-oil level and add oil if necessary. Every 50 hours • Change the engine oil.
PAGE 17
Checking the Engine-Oil Level Service Interval: Before each use or daily—Check the engine-oil level and add oil if necessary. g257528 Checking and Adjusting the Skids and Scraper 4. 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 Service Interval: Yearly—Check the skids and scraper and adjust them if necessary. uneven, adjust the skids to raise the scraper.
PAGE 18
Checking and Adjusting the Traction Cable Service Interval: After the first 2 hours—Inspect the traction cable and adjust it if necessary. Yearly—Inspect the traction cable and adjust or replace it if necessary. If the machine does not drive in the forward or reverse speeds or it drives when you release the traction lever, adjust the traction cable. g001021 Figure 26 1.
PAGE 19
Checking the Auger-Gearbox-Oil Level Service Interval: Yearly—Check the auger-gearbox oil and add oil if necessary. 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 30). Note: If needed, use pliers to assist in removing the pipe plug. g260108 Figure 28 3. Auger clutch arm 1. 1.5 mm (1/16 inch) 2. Frame 4. If the auger/impeller cable is not properly adjusted, do the following steps: 5. Loosen the jam nut (Figure 29).
PAGE 20
Changing the Engine Oil Service Interval: After the first 5 hours—Change the engine oil. Every 50 hours—Change the engine oil. Change the engine oil every 25 operating hours when operating the engine under a heavy load. 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 0.95 L (32 fl oz)* Oil viscosity Refer to Figure 33.
PAGE 21
Lubricating the Hex Shaft Replacing the Spark Plug Service Interval: Yearly—Lubricate the hex shaft. Service Interval: Every 100 hours—Replace the spark plug. Lightly lubricate the hex shaft yearly with automotive engine oil (Figure 34). WARNING Replacing the spark plug while the engine is hot can result in burns. Wait until the engine is cool to replace the spark plug. Use a Toro spark plug or equivalent (Champion® RN9YC or NGK BPR6ES). 1. Remove the boot (Figure 36). g001027 Figure 34 1.
