Determine the type of snow thrower you need by the size of the areas to be cleared. A two-stage, gas-powered snow thrower is the largest and most powerful variety. The two-stage thrower is self-propelled, has a high-speed, metal augur for gathering snow and an impeller that shoots the snow great distances.
Single-stage snow throwers cost less than two-stage models and use a rubber augur. Single-stage throwers are light and relatively easy to handle, but they also are more prone to tipping over than larger versions.
Electric, single-stage snow throwers are the least costly and smallest snow removal machines. Electric throwers work fine in small areas.
Regularly check nuts and bolts for tightness as the vibrations of a snow thrower will loosen them over time. Service the snow thrower's engine completely at least once a year by changing the oil and replacing the spark plugs. Add stabilizers to the gas tank to prevent the fuel from gumming up the carburetor. Mix the correct ratio of gas to oil if your snow thrower has a two-stroke engine.
Never reach into a running snow thrower to clean out a jam or clog. Make certain the machine is turned off or unplugged before attempting a repair. Do not remove shields or safety guards from the machine, and fill the thrower with gas and oil before starting. Avoid hitting rocks or pieces of metal with a snowthrower, as the object will be propelled long distances at high speeds. Keep an eye on the extension cord if you are using an electric snowblower, as running over it will slice the cord and could result in severe injury
