Before starting the snowthrower, clear the operating area. Pick up all sticks, doormats, toys, electrical cords or other debris that might cause damage to the snowthrower, you or others. Dress properly for the job. Wear warm clothing and shoes that will improve footing on slippery surfaces. Wear eye protection and avoid wearing loose fitting items that might get caught in the machine’s moving parts. Know how to stop a running snowthrower quickly. If the chute becomes clogged, do the following: Turn off the snowthrower and wait for all moving parts to stop. Remove the spark plug wire. Use a stick, not your hand, to remove the impacted snow. Keep all body parts clear of the chute at all times.
Look for dirty spots in your insulation, which often indicate holes where air leaks into and out of your house. You can seal the holes by stapling sheets of plastic over the holes and caulking the edges of the plastic.
