Safe Handling of Gasoline
To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.
a.Use only an approved gasoline container.
b.Extinguish all cigarettes, cigars, pipes and other sources of ignition.
c.Never fuel machine indoors.
d.Never remove gas cap or add fuel while the engine is hot or running.
e.Allow engine to cool at least two minutes before refueling.
f.Never over fill fuel tank. Fill tank to no more than ½ inch below bottom of filler neck to provide space for fuel expansion.
g.Replace gasoline cap and tighten securely.
h.If gasoline is spilled, wipe it off the engine and equipment. Move machine to another area. Wait 5 minutes before starting the engine.
i.Never store the machine or fuel container inside where there is an open flame, spark or pilot light (e.g. furnace, water heater, space heater, clothes dryer etc.).
j.Allow machine to cool at least 5 minutes before storing.
k.Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.
l.If possible, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.
m.Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
Operation
1.Do not put hands or feet near rotating parts, in the auger/ impeller housing or chute assembly. Contact with the rotating parts can amputate hands and feet.
2.The auger/impeller control lever is a safety device. Never bypass its operation. Doing so makes the machine unsafe and may cause personal injury.
3.The control levers must operate easily in both directions and automatically return to the disengaged position when released.
4.Never operate with a missing or damaged chute assembly. Keep all safety devices in place and working.
5.Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
6.Do not operate machine while under the influence of alcohol or drugs.
7.Muffler and engine become hot and can cause a burn. Do not touch. Keep children away.
8.Exercise extreme caution when operating on or crossing gravel surfaces. Stay alert for hidden hazards or traffic.
9.Exercise caution when changing direction and while operating on slopes. Do not operate on steep slopes.
10.Plan your snow-throwing pattern to avoid discharge towards windows, walls, cars etc. Thus, avoiding possible property damage or personal injury caused by a ricochet.
11.Never direct discharge at children, bystanders and pets or allow anyone in front of the machine.
12.Do not overload machine capacity by attempting to clear snow at too fast of a rate.
13.Never operate this machine without good visibility or light. Always be sure of your footing and keep a firm hold on the handles. Walk, never run.
14.Disengage power to the auger/impeller when transporting or not in use.
15.Never operate machine at high transport speeds on slippery surfaces. Look down and behind and use care when backing up.
16.If the machine should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.
17.Disengage all control levers and stop engine before you leave the operating position (behind the handles). Wait until the auger/impeller comes to a complete stop before unclogging the chute assembly, making any adjustments, or inspections.
18.Never put your hand in the discharge or collector openings. Always use the clean-out tool provided to unclog the discharge opening. Do not unclog chute assembly while engine is running. Shut off engine and remain behind handles until all moving parts have stopped before unclogging.
19.Use only attachments and accessories approved by the manufacturer (e.g. wheel weights, tire chains, cabs etc.).
20.When starting engine, pull cord slowly until resistance is felt, then pull rapidly. Rapid retraction of starter cord
(kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result.
21.If situations occur which are not covered in this manual, use care and good judgment. Contact Customer Support for assistance and the name of your nearest servicing dealer.

WARNING! Never use your hands to clear a clogged chute assembly. Shut off engine and remain behind handles until all moving parts have stopped
before unclogging.
The chute clean-out tool is conveniently fastened to the rear of the auger housing with a mounting clip. Should snow and ice become lodged in the chute assembly during operation, proceed as follows to safely clean the chute assembly and chute opening:
1.Release both the Auger Control and the Drive Control.
2.Stop the engine as instructed in the engine operator’s manual included with the snow thrower.
3.Remove the clean-out tool from the clip which secures it to the rear of the auger housing.
4.Use the shovel-shaped end of the clean-out tool to dislodge and scoop any snow and ice which has formed in and near the chute assembly.
5.Refasten the clean-out tool to the mounting clip on the rear of the auger housing, and start the engine as instructed in the engine operator’s manual.
6.While standing in the operator’s position (behind the snow thrower), engage the auger control for a few seconds to clear any remaining snow and ice from the chute assembly.

Starting and Stopping the Engine
Refer to the Engine Operator’s Manual packed with your snow thrower for instructions on starting and stopping the engine.
To Engage Drive
1.With the throttle control in the Fast (rabbit) position, move shift lever into one of the six forward (F) positions or two reverse (R) positions. Select a speed appropriate for the snow conditions and a pace you’re comfortable with.
NOTE: Use slower speeds in higher snow and/or until you are familiar with the snow thrower operation.
2.Squeeze the drive control against the handle the snow thrower will move. Release it and drive motion will stop.
CAUTION: NEVER move the shift lever without first releasing the wheel drive control. Doing so will cause premature wear on the drive system’s friction wheel
3.To turn the snow thrower to the left or right, squeeze the respective wheel steering control. Refer to Figure 4-1.
To Engage Augers
1.To engage augers and start throwing snow, squeeze the auger control against the left handle. Release to stop augers.
2.While the auger control is engaged, squeeze the drive control to engage the interlock mechanism and to drive the snow thrower. The interlock mechanism locks the auger control so you can turn the chute control without interrupting the snow throwing process.
3.Release the auger control; the interlock mechanism keeps the auger control engaged until the drive control is released.
4.Release the drive control to stop both the augers and the wheel drive. To stop auger, both levers must be released.
Operating Tips
NOTE: Allow the engine to warm up for a few minutes. The engine will not develop full power until it reaches operating temperature.
WARNING: The temperature of the muffler and the surrounding areas may exceed 150° F. Avoid these areas.
1.If possible, remove snow immediately after it falls.
2.Discharge snow downwind whenever possible.
3.Slightly overlap each previous path.
4.Set the skid shoes 1/4” below the shave plate for normal usage. Adjust them upward for hard-packed snow and downward when using on gravel or crushed rock.
Replacing Shear Pins
Each of the auger spiral assemblies are secured to the spiral shaft with a shear pin and bow-tie cotter pin. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. If the augers will not turn, check to see if the pins have sheared. See Figure 5-1.
CAUTION: NEVER replace the auger shear pins with anything other than OEM Part No. 738-04155 replacement shear pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.

Maintenance & Adjustments
WARNING! Before performing any type of maintenance/service, disengage all controls and stop the engine. Wait until all moving parts have come to a complete stop. Remove the key to prevent unintended starting. Always wear safety glasses during operation or while performing any adjustments or repairs.
Engine
Refer to the Engine Operators Manual Maintenance section included with the snow thrower.
Lubrication
Drive and Shifting Mechanism
At least once a season or after every 25 hours of operation, remove rear cover. Lubricate all chains, sprockets, gears, bearings, shafts, and the shifting mechanism. Use engine oil or a spray lubricant. Refer to Figure 6-3.
NOTE: Before tipping the unit on the front housing, run the fuel tank empty so fuel does not leak out of the fuel cap.
1.Carefully pivot the snow thrower up and forward so that it rests on the auger housing.
2.Remove the frame cover from the underside of the snow thrower by removing the self-tapping screws which secure it. Refer to Figure 6-8.
3.Apply a light coating of engine oil (or 3-in-1 oil) to the hex
shaft. See Figure 6-3.
NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum drive plate or the rubber friction wheel. Doing so will hinder the snow thrower’s drive system. Wipe off any excess or spilled oil.
4.At least once a season grease the wheel axle with Arctic grease, part number 737-0318. The grease fitting is located on the wheel axle tube behind the wheel axle support bracket.

Wheels
At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels.
Chute Directional Control
Once a season, lubricate the eye bolt bushing and the spiral with 3-in-1 oil.
Auger Shaft
At least once a season, one at a time, remove all of the shear pins from the auger shaft. Spray lubricant inside the hub of each auger spiral assembly and around the spacers on the auger shaft.
Grease fittings can also be found at each end of the auger shaft.
Lubricate with a grease gun once a season. See Figure 6-4.
Gear Case
The auger gear case is equipped with a grease fitting. Lubricate with grease once a season (order part number 737-0168). See Figure 6-4.
NOTE: To relieve pressure, remove the vent plug before lubricating the gear case. See Figure 6-4. Failure to do so could result in damage to the gear case seals.
Augers
Each of the auger spiral assemblies is secured to the spiral shaft with a shear pin and cotter pin. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear.
1.If augers do not turn, check to see if pins have sheared.
2.Replace the pins if needed. Two replacement shear pins and cotter pins have been provided with the snow thrower. Spray an oil lubricant into shaft before inserting new pins and securing with new cotter pins. See Figure 6-4.
