Before you start the product
To fill the engine with oil
Do not rotate the dipstick when you check the oil. Do not fill above the mark.
To fill fuel
If available, use low-emission/alkylate gasoline. If low-emission/alkylate gasoline is not available, use good quality unleaded gasoline or leaded gasoline. Use gasoline with an octane number of 90 RON out of North America (87 AKI in North America) or higher, and with a maximum of 10% ethanol (E10).
Do not use gasoline with an octane number less than 90 RON out of North America (87 AKI in North America). This can cause damage to the product.

The product has a 120 V A.C. electric starter. Do not use the electric starter if your house is not a 120 V A.C. three-wire grounded system. Serious personal injury or damage to the product could occur. The electric starter has a three-wire power plug, and is designed to use 120 V A.C. household current. Make sure that your house is a 120 V A.C. three-wire grounded system. If you are uncertain, ask a licensed electrician.
To operate the product
Do not operate without snow or water to lubricate the auger blades. Incorrect use can cause high temperatures in the auger blades, especially if the product is new. This can cause damage to the auger blades and scraper bar.
Do not partially engage drive or auger levers for an extended period of time; this can lead to premature wear or burning of the belts.
Note: When both the drive engagement and auger engagement are engaged, the drive engagement will lock the auger engagement in position. Use the right hand to control the snow discharge chute.
Note: Do not change the speed when the drive lever is engaged. This can cause damage to the transmission.
To stop the product
To use the throttle control
To use the fuel switch
To use the choke control
To adjust the skid plates
No adjustment is required for normal installation.
To prevent freeze-up after use
Note: Controls and moving parts can be blocked by ice. Do not apply much force to the controls. If you cannot operate a control or a part, start the engine and let it operate for some minutes.
