FILL THE FUEL TANK
This engine is certified to operate on gasoline. Exhaust Emission Control System: EM (Engine Modifications).
Fill the fuel tank with fresh, clean, unleaded regular, unleaded premium, or reformulated automotive gasoline with a minimum of 85 octane along with a fuel stabilizer (follow instructions on fuel stabilizer package). D use leaded gasoline. We recommend that fuel stabilizer be added to the fuel each time that gasoline is added to the fuel tank.
NOTE: Winter grade gasoline has higher volatility to improve starting. Be certain container is clean and free from rust or other foreign particles. Never use gasoline that may be stale from long periods of storage in the container.
CAUTION: DO NOT use gasoline containing any amount of alcohol as it can cause serious damage to the engine or significantly reduce the performance.
WARNING: Gasoline is flammable. Always use
caution when handling or storing gasoline. Turn engine off and let engine cool at least two minutes before removing the gas cap. Do not add gasoline to the fuel tank while snow thrower is running, hot, or when snow thrower is in an enclosed area. Keep away from open flame, electrical sparks and DO NOT SMOKE while filling the fuel tank. Never fill the fuel tank completely; but fill the fuel tank to within 1-1/2 inches (3.8 mm) from the top to provide space for the expansion of the fuel. Always fill fuel tank outdoors and use a funnel or spout to prevent spilling. Make sure to wipe up any spilled fuel before starting the engine.
Store gasoline in a clean, approved container, and keep the cap in place on the container. Keep gasoline in a cool well ventilated place; never in the house. Never buy more than a 30 day supply of gasoline to assure volatility. Gasoline is intended to be used as a fuel for internal combustion engines; therefore, do not use gasoline for any other purpose. Since many children like the smell of gasoline, keep it out of their reach because the fumes are dangerous to inhale, as well as being explosive.
START THE ENGINE
Be sure that engine oil is at FULL mark on the oil fill cap/dipstick. The snow thrower engine is equipped with an A.C. electric starter and recoil starter. Before starting the engine, be certain that you have read the following information.
If engine floods, set the choke to the OPEN/RUN position and crank until the engine starts.
WARNING: The electric starter is equipped with a three−wire power cord and plug designed to operate
on AC house hold current. The power cord must be properly grounded at all times to avoid the possibility of electric shock which can cause injury to the operator. Follow all instructions carefully as set forth:
Make sure your house has a three−wire grounded system. If you are not sure, ask a licensed electrician. If your house
does not have a three−wire grounded system, do not use this electric starter under any condition.
If your house has a three−wire grounded system but a three-hole receptacle is not available to connect the electric starter, have a three−hole receptacle installed by a licensed electrician.
WARNING: To connect power cord, always connect the power cord first to the switch box located on the engine and then plug the other end into a three−hole grounded receptacle.
WARNING: To disconnect the power cord, always unplug the end connected to the three−hole grounded receptacle first.
Start the engine as follows:
1. Check the oil level. See the “Check/Add Oil” section in the ENGINE MANUAL.
2. Make sure equipment drive controls are disengaged.
3. Push the ON /OFF switch (A
4. Insert the safety key (AA, Figure 18) into the safety key slot and push fully in to the RUN position.

7. Rewind Start: Firmly hold the starter cord handle (AA, Figure 19).
Pull the starter cord handle slowly until resistance is felt, then pull rapidly.
WARNING: Rapid retraction of the starter cord (kickback) will pull your hand and arm toward the engine faster than you can let go. Broken bones, fractures, bruises, or sprains could result. When starting engine, pull the starter cord slowly until resistance is felt and then pull rapidly to avoid kickback.
NOTE: If the engine does not start after three attempts, see the Engine Manual Troubleshooting section.
8. Electric Start: First connect the extension cord to the power cord
receptacle and then into a wall receptacle. If additional extension cord is required, make sure it is three-wire.
WARNING: If the extension cord is damaged, it must be replaced by the manufacturer (or its service agent) or a similarly qualified person to avoid a hazard.
9. Electric Start: Depress the starter push button (AA, Figure 20). After
you start the engine, first disconnect the extension cord from the wall receptacle and then from the power cord receptacle (BB).
IMPORTANT: To extend the life of the starter, use short starting cycles (five seconds maximum). Wait one minute between starting cycles.
NOTE: If the engine does not start after three attempts, see the Engine Manual Troubleshooting section.
STOP THE ENGINE
Before stopping the engine, allow it to run for a few minutes to help dry off any moisture on the engine.
WARNING: Gasoline and vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. DO NOT choke the carburetor to stop the engine.
1. Push the ON/OFF switch (A
2. Remove the safety key (BB). Keep the safety key out of the reach of children.
, Figure 21) to the OFF position.
CLEAR A CLOGGED DISCHARGE CHUTE
DANGER: Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never clear or unclog discharge chute with your hands, or while engine is running. Fingers can quickly become caught and traumatic amputation or severe laceration can result.
A clean-out tool (AA, Figure 22) is attached to either the handle or the top of the auger housing. Use the clean-out tool to remove snow from the auger housing.
OPERATING TIPS
1. Most efficient snowthrowing is accomplished when snow is removed immediately after it falls.
2. For complete snow removal, slightly overlap each swath previously taken.
3. Snow should be discharged downwind whenever possible.
4. For normal usage, set the skids 1/8 inch (3 mm) below the scraper bar. For extremely hard-packed snow surfaces, the skids may be adjusted upward to ensure cleaning efficiency.
5. On gravel or crushed rock surfaces, the skids should be set at 1-1/4 inch (32 mm) below the scraper bar (see “Adjust Skid Height” in the MAINTENANCE section of this manual). Rocks and gravel must not be picked up and thrown by the machine.
6. After the snowthrowing job has been completed, allow the engine to idle for a few minutes, to melt snow and ice accumulated on the engine.
7. Clean the snow thrower thoroughly after each use.
8. Remove ice and snow accumulation and all debris from the entire snow thrower, and flush with water (if possible) to remove all salt or other chemicals. Wipe snow thrower dry.
9. Before starting snow thrower, always inspect augers and impeller for ice accumulation and/or debris, which could result in snow thrower damage.
10. Check oil level before every start. Make sure the oil is at the FULL mark on the oil fill cap/dipstick.
NOTE: Do not lose the safety key. Keep the safety key in a safe place. The engine will not start without the safety/ignition key.
