The snow thrower has been shown here from an upside down perspective in order to better explain the controls. Please note that the snow thrower cannot be operated in this position.

Figure 10

(Refer to Figure 10 for illustration of controls described below.)

SHIFT LEVER

The shift lever is located in the center of the handle panel. The shift lever may be moved into one of eight positions. Use the shift lever to determine ground speed.

Forward—one of six speeds. Position number one

(1) is the slowest. Position number six (6) is the fastest.

Reverse—two reverse (R) speeds. “R” closest to the operator (all the way back) is the faster of the two.

AUGER DRIVE

The auger drive clutch is located on the left handle. Squeeze the clutch grip to engage the augers. Release to stop the snow throwing action. (Traction drive clutch must also be released.)

TRIGGER LEVER

The left and right turn triggers are located on the underside of the handles and are used to assist in

steering your snowthrower. Squeeze the right turn trigger when turning right and the left trigger when turning left.

TRACTION DRIVE/AUGER CLUTCH LOCK

The traction drive clutch is located on the right handle. Squeeze the traction drive clutch to engage the wheel drive. Release to stop.

This same lever also locks the auger clutch so you can turn the chute crank without interrupting the snow throwing process. If the auger drive clutch is engaged with the traction drive clutch engaged, the operator can release the auger drive clutch (on the left handle) and the augers will remain engaged. Release the traction drive clutch to stop both the augers and wheel drive (auger drive clutch must also be released).

CHUTE CRANK

The chute crank is located on left hand side of the snow thrower.

To change the direction in which snow is thrown, turn chute crank as follows:

1.Crank clockwise to discharge to the left.

2.Crank counterclockwise to discharge to the right.

CHUTE TILT CONTROL

The distance snow is thrown can be adjusted by adjusting the angle of the chute assembly. Move the chute tilt control forward to decrease the distance, toward the rear to increase.

HEADLIGHT

The headlight is on whenever the engine is running.

THROTTLE CONTROL

The throttle control is located on the engine. It regulates the speed of the engine. When blowing snow, always run engine with throttle in the fast position.

SAFETY IGNITION SWITCH

The ignition key switch must be inserted completely in the switch before the unit will start. Do not attempt to turn the key.

FUEL SHUT-OFF VALVE

The fuel shut-off valve, located under the fuel tank, controls fuel flow from tank. Make sure it is not turned off before starting the engine.

SECTION 7: OPERATION

GAS AND OIL FILL-UP

Service the engine with gasoline and oil as instructed in the separate engine manual packed with your snow thrower. Read instructions carefully.

WARNING: Never fill fuel tank indoors, with engine running or while engine is hot. Do not smoke when filling fuel tank.

Electric Starter

WARNING: The electric starter is equipped with a three-wire power cord and plug, and is designed to operate on 120 volt AC household current. It must be properly grounded at all times to avoid possibility of electric shock which may be injurious to the operator. Follow all instructions carefully. Determine that your house wiring is a three-wire grounded system. Ask a licensed electrician if you are not certain. If your house wiring system is not a threewire grounded system, do not use this electric starter under any conditions. If your house wiring system is grounded but a three-hole receptacle is not available at the point the starter will normally be used, one should be installed by a licensed electrician.

When connecting the power cord, always connect cord to starter on engine first, then plug the other end into a three-hole grounded receptacle.

When disconnecting the power cord, always unplug the end from the three-hole grounded receptacle first.

TO START ENGINE

(See Figure 11)

IMPORTANT: If unit shows any sign of motion (drive or augers) with the clutch grips disengaged, shut engine off immediately. Readjust as instructed in the “Final Adjustments” section of the Set-Up Instructions.

1.Attach spark plug wire to spark plug. Make certain that the metal loop on the end of the spark plug wire (inside the boot) is fastened securely over the metal tip on the spark plug.

2.Make certain the fuel shut-off valve is in the open (vertical) position.

3.Make certain the auger and drive clutch levers are in the disengaged (released) position.

4.Move throttle control to FAST position.
