Things You'll Need
Spark plug socket
Always clean the snowblower after use.
Disconnect the spark plug wire and place it away from the plug before starting any maintenance. Allow sufficient time for snowblower to cool before starting any maintenance.
Husqvarna produces a range of snowblowers designed to move snow using a two-stage auger and impeller system. Problems can occur, and it may be worth troubleshooting the blower yourself before making a potentially expensive service call. The various models have different specifications but all use the same basic system and the troubleshooting steps are applicable to each.
The Snowblower Won't Start
Turn the fuel shut-off valve to "Open" position.
Insert safety ignition key.
Fill fuel tank with gasoline.
Ensure "On/Off" switch is switched to "On."
Turn choke knob counterclockwise until it reaches "Full" position.
Push the primer twice if the temperature is between 15°F and 50°F. Push the primer four times if the temperature is lower than 15°F. You don't need to prime it if the temperature is above 50°F.
Ensure the spark plug wire connects securely. Tighten, if required, by pushing firmly on the connector cap.
Remove spark plug wires by pulling on the connector cap. Do not pull the wire itself. Remove the spark plug by using a wrench with a spark plug socket and turning clockwise. Insert a new spark plug and reconnect the wires.
Disconnect the fuel line under the tank and drain fuel into a suitable container. Clean the fuel line with cold water. When dry, reconnect the fuel line and refill the tank with fresh gasoline.
Grasp the recoil starter handle and slowly pull as much rope out of the starter as possible. Release the handle and let it snap back against the starter.
The Snowblower Starts but Operation is Impaired
Remove any ice and snow from on or around the fuel cap.
Clean the muffler and remove any debris from the augers, impeller and snow chute.
Turn choke off by turning knob clockwise until it reaches the "Off" position.
Check to see if the auger or drive belts are worn or have slipped off their pulleys. Replace or reinstall the belts, if required, by following the steps below.
Replacing the Auger and Drive Belts
Drain gasoline from the fuel tank. Loosen the locknut securing the chute rotator head to its mounting head. Lift the chute rotator head and remove the discharge chute. Remove belt cover by unscrewing the two screws connecting it to the frame. Remove the bolt securing the outside pulley to the engine crankshaft. Then remove the pulley from the crankshaft. Remove the two bolts holding the auger housing and frame together while your assistant holds the handles with the snowblower in the operating position. Carefully pull the auger housing and frame apart.
Remove the auger belt from the auger pulley. Insert a 3/8" ratchet into the square hole in the idler arm and rotate clockwise to relieve tension. Remove the drive belt from the drive pulley.
Put a new auger belt on the auger pulley and a new drive belt on the drive pulley, being sure to seat both in the pulley grooves.
Bring the auger housing and frame together and replace the two connecting bolts. Bring the auger pulley and crankshaft together and replace the connecting bolt. Attach the belt cover with the two connecting screws.
Position discharge chute on top of chute base with the discharge opening facing the front of the snowblower. Position chute rotator head over chute bracket and secure to the mounting head with the locknut.
