Now that winter is upon us, cleaning snow can be a daunting task for most residence. Especially in more recent winters our region has received it’s fair share of snowfall and storms. It’s important to be prepared with the right tools to weather any storm safely.
Safety while using a snowblower:
It’s here. This time of the year means one of two things: fluffy white landscapes reflecting a season of merriment or months of wet blizzards with blinding, wind-driven snow. Whatever your feelings about winter, you don’t want to get caught in the storm unprepared.
If you’re notorious for waiting until the last minute and wake up one day to strong winds, flurries and freezing rain, here’s a quick emergency survival guide for a snow blower that won’t start. Start from the top of the list and move down until any snow equipment problem is remedied
Check Fuel Tank
Look to see if it is low or empty. When gasoline is stored over a long period of time and no fuel stabilizer is added, it loses volatility. As gasoline ages it turns into a varnish like coating in the carburetor, blocking fuel from the engine and preventing start.
If this occurs, take your Sno-Thro to your local Ariens servicing dealer to clean your carburetor or replace it.
If the fuel is from last winter, summer, or fall season and/or no fuel stabilizer was added before storage, drain the system through the carburetor. Once drained, pour in known fresh fuel (purchased within 30 days) and a fuel stabilizer
Check Fuel Shutoff Valve
Check if the engine switch is in the OFF position. If it is, turn the switch to the ON position.
Check Engine Switch
Many of the engines on Ariens Sno-Thro units have a “key switch” and a red toggle switch. Ensure that the red plastic key is properly inserted into the holder and the red toggle switch is in the “run” position. If either is not in the correct position, the engine will not fire causing the chance of flooding.
Check Choke Position
Check the choke position; turn to ON position for cold engine starts. Always use the choke to start a cold engine, turning to “Full Choke.” Check your Owner's Manual for proper choke positioning.
If the temperature is above 32 degrees, priming the carburetor may flood the engine easily so try only choking the engine.
Check Throttle Position
Check the throttle position (if applicable); turn throttle position to at least 3/4 speed.
Check Spark Plug
Check the spark plug for fuel and correct air gap. Remove the spark plug and see if it is wet (this will confirm flooding). If the spark plug is wet, turn the engine over several times without the spark plug installed to help disperse the excess fuel out of the spark plug hole. Clean the spark plug of excess fuel and reset the air gap. Reinstall the cleaned spark plug or replace with a new spark plug. Perform starting procedure again, this time without the choke on.
If all of these items are checked and the unit will not start, take your unit to an Ariens servicing dealer.

Does your snow thrower have the flu?
You may find that during a snowstorm the snowblower auger (s) stops turning all of a sudden.
This may be due to broken auger shear bolts. Luckily it's a simple and inexpensive fix.The purpose of auger pins or bolts are to act as a safety mechanism to prevent any severe damage due to overload. So, if you were to go thru heavy snow or catch something in the auger, the bolts 'shear' to prevent any damage to the auger differential gears.
When you break a shear pin, make sure to replace it with the proper bolts or pin made for your machine. Don't use any ordinary bolt or nail because they may not break under heavy load and can cause major damage. It's always a good idea to keep couple of spares in case you need them .
Other causes of snowblower not throwing snow:
- Loose/worn Auger belt
- Worn impeller bearing
- Broken impeller bolts
- Worn differential gears
