Snow blowing 101

Running a snow blower seems like a skill you could master in two minutes. But we wondered: If it’s really that simple, why are there 6,000 blower-related injuries in the United States every year? And why do repair shops get overwhelmed after a big storm?

To get answers, we talked with experts at all the major manufacturers—as well as the guys who fix blowers. It turns out that operator error is the No. 1 cause of clogs and breakdowns, and improper clearing of clogs is the most common cause of injuries. The experts shared some great tips on how to avoid both. So even if you’re an experienced snow blower operator, read on.

Don’t wait for it to stop

If you’re in for a huge snowfall, start clearing the snow before it reaches 6 in. Sure, you’ll spend more time snowblowing, but your machine won’t have to work as hard, and it’ll throw the snow farther. That’ll reduce the height of the snowbanks flanking your driveway.

Get your property ready for snow

Before the snow flies, take a few minutes to inspect your property. Remove rocks, dog tie-out cable, extension cords, holiday light cords and garden hoses. Then stake out paths that run near gardens so you don’t accidentally suck up rocks and garden edging. Mark your walk and driveway perimeters by pounding in driveway markers. If the ground is frozen, just drill a hole using a masonry bit and your battery-powered drill.

Start With Fresh Fuel

Stale gas is the No. 1 cause of hard starting. So don’t use what’s left in the lawn mower can. It’s better to dump that summer blend into your car’s tank, then refill the can with winter blend, which is more volatile and provides better starting.

Take smaller bites to avoid clogs

Cool Off, Then Gas Up

If your snow blower runs out of gas halfway through a tough job, you’ll be tempted to refill it right away. But think about this: The engine is hot and the gas tank sits right on top of that hot engine. Even worse, you’re standing right over the machine holding a gallon of gas. If you spilled gas on the engine or overfilled the tank, you could instantly turn your snow-blowing adventure into a painful burn-unit experience. Even if you managed to escape injury, you could still wind up with a freshly toasted snow blower.

Snow-blower fires happen often enough that the manufacturers strongly recommend that you let the engine cool for at least 10 minutes before refilling. Take that opportunity to grab a cuppa joe or hot chocolate and warm up your fingers and toes. Then, once your personal tank is refilled, refill your snow blower and carry on.

Add stabilizer to the fresh fuel

Switch to Synthetic Oil for Easier Starting

Small engines typically have to reach at least 400 rpm before they’ll fire up. But traditional motor oil thickens when cold, making it much harder to reach that 400-rpm threshold. Synthetic oil allows the engine to spin faster when you yank the cord, so it starts with fewer pulls.

Pre-season maintenance

Get your snow blower ready for action by installing a new spark plug, changing the oil and checking the condition of the belts. Replace the belts if you see cracks, fraying or glazing or notice that chunks are missing.

Next, sand any rusted areas and repaint. Once the paint cures, apply a high-quality polymeric car wax to all painted surfaces. The wax will shed the snow and water and protect the paint. And, wax the inside of the chute to help prevent clogs.

Then consult your owner’s manual to find the lubrication points and the recommended lube. If the type of lube isn’t listed, here’s some general guidance: Use motor oil on metal linkage joints, gears and cables, but dry PTFE lube on plastic parts (knobs, gears and chute). Spray the auger, second-stage impeller and chute with silicone spray to prevent snow from sticking.

Buy parts before you need them

Belts and shear pins always break on a Sunday night in the middle of a blizzard. So buy replacement parts at the start of the season when everyone has them in stock. If you break a shear pin and try to improvise using the wrong shear pin—or worse yet, an ordinary bolt—you risk major damage that can easily cost you $200. A set of belts and a few extra shear pins will cost about $25. Also make sure you have the right size of wrenches and sockets and the correct size pin punch to drive out the broken pin. Then assemble a parts and tool kit.

Prevent major auger damage

The drive shaft applies torque to the shear pin, which then applies it to the auger. However, if the auger rusts to the drive shaft, they’ll become one and the shear pin will never break. If that happens, the auger clog can cause major damage to the machine. Lubricate the drive shaft to prevent it from rusting to the auger.
